General danger warning

Information about danger due to electrical voltage

Important information

General Information

General danger warning: The dosing fluids used are corrosive and or inflammable. Never allow the two ends of the pressure hoses on vacuum pumps to hang loose, as this will permit the corrosive and inflammable fluids to escape.

Important: During installation and operation, always observe the relevant health and safety regulations when installing and using the device. It must only be installed and operated by qualified expert personnel.

General danger warning: Changing the system settings (default values) can be dangerous to persons under certain circumstances. Therefore, changes must only be made by trained technicians. The operator assumes liability if the equipment is used improperly or the settings are modified incorrectly!

General danger warning: The system must be switched off immediately and protected against being switched on again if it is probable that the system cannot be operated safely and without danger. This is the case, for example, if • the system is visibly damaged, • the system no longer appears to be functional for whatever reason, • the system was stored for lengthy periods under unfavourable conditions (e.g. improper winter

storage)

1 Installing the pH FUN Perform all installation work carefully and comply with the applicable safety regulations.

Important: In addition, comply with the applicable regulations regarding the installation of electrical devices. During installation, disconnect the measurement, control and dosing device and all other electrical loads such as the electrical heating or the circulating pump from the mains.

1.1 General notes on installation: • Ensure that the hoses are laid without kinking and that chafing cannot occur. • Avoid laying the hoses over sharp edges. • Carefully connect all hoses and check that the connections are firmly attached. • Avoid unnecessarily long hose lengths. • Do not guide the hoses directly over heat-conducting pipes or systems. • Check that the float in the measurement chamber can float freely. • Adjust the water flow through the cell so that the float just barely lies against the upper end in its guide bore.

• Ensure that connections and hose connections are tight.

1.2 Selecting the installation location To mount pH FUN, select a dry, frost-protected, sheltered and level location on a vertical wall. Ensure that the area is readily accessible and well-ventilated. There should be no energised electrical cables, contactors, electric motors, etc. in its vicinity. The installation location should be as close as possible to where the measurement water is extracted and returned.

1.3 Mounting the pH FUN on the wall • The base plate with the mounted controller and measurement cell can be used as a drilling template by holding

it up against the mounting location and marking the drill holes on the wall. • After the holes have been drilled in the wall, securely attach the pH FUN to the wall using suitable countersink

screws.


Page 6 of 28

1.4 Installing the measurement water circuit • Place the measurement water extractor and return as shown in the installation plans (see Chapter 2.8). To do

this, use saddle clamps into which you then screw in the measurement water extractor and measurement water return.

• Connect the measurement water extractor and prefilter at the measurement chamber of the pH FUN using a piece of measurement water hose.

• Connect the measurement water return and output of the measurement chamber of the pH FUN using a section of measurement water hose.Electrical connection

The system has been designed and constructed according to the applicable regulations. It was carefully inspected before leaving the factory and left the factory in a perfectly safe condition. The equipment can only be operated safely if all of the instructions contained in this manual are followed. The equipment should be installed by a licensed electrician. The supply voltage for the device may not exceed 240V/50 Hz. The allowable operating temperature range is from 0 to 50OC, and the allowable humidity level equals 0-90%. Ensure that all plug-in connections are protected against water, as is standard practice for electrical connections.

Danger warning: For safety reasons, the pH FUN should be connected in such a way so that it is only supplied with current when the circulating pump is running. Together with the float switch in the measurement cell, this ensures the maximum amount of operational safety. It is thus impossible for the dosing pump to dose pH-Minus (pH-Plus) into standing water.

1.5.1 Connections on the controller housing

Page 7 of 28

1.5.2 Earthing of the pH value measurement Measurement water extractor and return are each provided with an earthing. These earthings ensure that any interfering electrical potentials that may possibly be present in the pool water are safely diverted.

Note: The supplied earthing of the measurement water extractor and return MUST be installed. This earthing MUST be run to a separate secure earthing. Always ensure that fault current is not flowing into the water of the swimming pool. Professional measurement is recommended.

1.6 Connecting the dosing line for pH-Minus Connect the supplied pH pressure line on one side with the pressure side (right connector) of the vacuum pump. Connect the other side with the injection piece at the measurement cell (only BAYROL pH-Minus; BAYROL pH-Plus is directly dosed in the circulating line via an injection piece, see following chapter). Connect the suction line which is located on the suction lance with the suction input (left connection) of the dosing pump. Ensure that all connections are tight and securely fastened.

1.7 Dosing of pH-Plus (increase of the pH value)

Danger warning: Should pH-Plus be utilised for increasing the pH value instead of pH-Minus for reducing the pH value, the pH-Plus may not be feed into the measurement cell, it must be fed directly into the circulating line.

You will require the following accessories (available at your BAYROL dealer): • 100 509 PE hose (length depending on the installation situation) • 171 207 Injection piece 0.5 bar (1 piece) • 112 283 PVDF Plug screw (1 piece) • 112 174 Saddle clamp 50mm ½“

or 112 148 Saddle clamp 63mm 1“ + 112 151 Adapter 1“-1/2“ or 112 149 Saddle clamp 75mm 1“ + 112 151 Adapter 1“-1/2“ (dependent on the pipe diameter of the circulation system in each case)

Installation: • If possible, fit the saddle clamp for the injection piece for pH-Plus directly in front of the return of the water to the

pool, but after all built-in parts (e.g. heat exchanger) into the circulation system. • Screw in the injection piece 171 207 into the threads of the saddle clamp. Ensure a secure sealing. • Remove the upper white PVDF elbow on the measurement chamber of the pH FUN and instead screw in the PVDF

plug screw 112 283 in the measurement chamber. Ensure a secure sealing. • Connect the PE hose 100 509 to the pressure side of the pH dosing pump of the pH FUN. Run this hose in the

most direct path as possible to the injection piece. Do not run the hose over sharp edges and do not run it directly past heat-conducting pipes. Ensure a secure and tight connection at pH dosing pump and injection piece.

• Connect the suction line which is located on the suction lance with the suction input (left connection) of the dosing pump. Ensure that all connections are tight and securely fastened.

2 Putting into operation Before putting the system into operation, all previously described steps must be performed and the conditions specified there must be met! Then proceed as follows:

• Insert the suction lance into the full canister with pH-Minus (pH-Plus) and tighten the screw connection firmly. Ensure that the tip of the suction lance with the switch is located at the very bottom of the canister.

• Connect the BNC connectors of the suction lance with the socket on the lower side controller (see also Chapter 1.5.1 Connections on the controller housing

• Connect the pH FUN to the mains (connection via the power supply of the circulating pump). The menu for the initial operation is then displayed.

Initial operation menu of the pH FUN The initial operation menu appears automatically after a new pH FUN device is switched on for the very first time. This menu guides you through the most important settings:

• Language Select the desired language using the arrow keys and confirm with .

• Default Select the default value set (standard settings) corresponding to your location using the arrow keys . There are 5 sets available. Use "Europe" for all countries not listed. Confirm with .

• Pool volume Enter the volume of the swimming pool in m³ (cubic meter) using the arrow keys and confirm with . The input of the pool volume serves as basis to the pH FUN for the determination of the optimal dose amount.

• pH7-Calib. Perform the pH7-Calib. (calibration of the pH measurement) to guarantee a correct and precise measurement of the pH value in the pool water. Please proceed as described in Chapter 6 Performing the pH7 calib.

• To ensure that the pH FUN is able to quickly and safely perform its measuring and controlling function from the very beginning, it is recommended that you bring the pH value of the pool water to the optimal value (pH setpoint) of 7.2 manually. To do this, you can trigger a manual dosing (see Chapter 5 Performing a manual dosing). You can read the current pH value on the display of the pH FUN. Alternatively, for larger deviations of the pH value, you can also utilise pH-Minus/pH-Plus from BAYROL in granular form. Here you must absolutely observe the dosing instructions on the product packaging. A check of the pH value is possible using a commercially available pool tester. You can also perform this step before putting the pH FUN into operation.

• Once the pH value is in the optimal range, you can proceed with your preferred method for water disinfection.

3 Maintaining the pH FUN

ATTENTION: Disconnect all power connections before beginning maintenance work!

3.1 Maintenance plan Monthly maintenance:

• Visually inspect all dosing lines and hoses for leakage • Check the filter sieve and clean it if necessary. Repeat this step more often for strong contamination. • Check the pH value using a test kit (commercially available), adjust the settings if necessary

Quarterly maintenance: • Visually inspect all dosing lines and hoses for leakage's • Check the filter sieve and clean it if necessary • Check the pH value using a test kit (commercially available), adjust the settings if necessary • Calibrate the pH electrode with supplied buffer solution (see Chapter 6 Performing the pH7 calib)

Annual maintenance: • Visually inspect all dosing lines and hoses for leakage's • Check the filter sieve and clean it if necessary • Check the pH value using a test kit (commercially available), adjust the settings if necessary • Replace and calibrate the pH electrode with supplied buffer solution (see Chapter 6 Performing the pH7 calib) • Replace the hoses of the dosing pumps

3.1.1 Checking the hoses Check all hoses for damage (e.g. kinks, tears or leakage's), contamination (e.g. leaves, hair, dust or earth) and deposits (e.g. limescale). If there is any doubt, always replace the affected lines. This is the only way to ensure a proper operation.

3.1.2 Cleaning the filter Close the valve of the measurement water extractor and then the valve of the measurement water return. No further water is now transported through the measurement cell and filter and the float of the flow switch sinks downwards. Now unscrew the transparent cover of the filter. Use a container to catch any water that runs out. Remove the filter sieve and clean it carefully. Use clear water to rinse it. Now reinsert the filter securely in its seat and screw on the cover again. Make sure the connection is tight.

3.1.3 Dosing pump hoses The hose of the dosing pump must be replaced annually or earlier if worn. Use the original replacement hose only. You can obtain this at your swimming pool dealer under BAYROL Art. no.: 171 219 Replacement hose set 0.9 l/h (identifiable by the white hose nozzles).

Like the pH electrode, the hose of the dosing pump is also a wear part and is exempted from the guarantee/warranty.


Page 11 of 28

3.1.4 Replacing hoses To replace the hoses, please proceed as follows:

• Rinse the pump with fresh, lukewarm water for about 30 minutes. To do so, place the suction lances into a pail filled with tap water and start a manual dosing (see Chapter 5 Performing a manual dosing).

• Subsequently ensure that the system is fully disconnected from the power grid. This prevents the pump from switching on during the maintenance procedure.

• Remove the blue cover of the pump, loosen the sleeve nuts on the hose (2) and remove the suction and pressure hose.

• Press the band (1) together at the recessed grips and turn the catch (4) clockwise all the way. • Move both hose ends outward and remove the band (1) with the hose (2). • Pull the old hose (2) out of the two guides and insert the new hose. • To mount the band (1) and hose (2), proceed in reverse order. Ensure that the hose (2) is firmly seated in the

guides and that the catch (4) has engaged. • As soon as all connections have been closed, you can purge the air from the dosing hose. To do so, connect

pH FUN with the mains and start a manual dosing. The purging is complete when you can no longer detect air bubbles on either the suction side (canister – pump) or on the pressure side (pump – measurement cell for pH-Minus or injection piece for pH-Plus dosing).

3.2 Electrode information The electrodes must be replaced according to the maintenance plan annually or earlier if worn. Use original replacement electrodes only. These can be obtained from your swimming pool dealer under BAYROL Art. no.: 185 301. Like the dosing hose, the pH electrode is also a wear part and is exempted from the guarantee/warranty.

3.2.1 Electrode wear The following conditions, among others, indicate that the electrodes are worn:

• During the pH7 calibration procedure, the electrode takes unusually long to reach the value of the buffer solution.

• The deviation of the electrode during the pH7 calibration procedure is too large, the pH7 calibration is not possible.

• The white KCL salt rings in the electrode are used up or discoloured.

ATTENTION: Electrodes wear very quickly if there is an electrical potential on the pool water!

3.2.2 Electrode care • The pH-sensitive membrane glass must be handled with care and protected against damage. • The inner reference solution in the glass electrode must cover the inner surface of the membrane glass. Any

air bubbles are removed by gently shaking the electrode vertically (like shaking a medical thermometer). Contamination deposited on the surface of the membrane glass must be removed by carefully wiping it with a moist paper towel. Alternatively, you can use the supplied electrode cleaning solution.

3.2.3 pH7 Calibration of the electrode For instructions on the pH7 calibration of the electrode, please refer to 6 Performing the pH7 calib.

3.3 Decommissioning / Winter storage of the system If the system is put out of operation for lengthy periods, e.g. for winter storage, certain precautionary measures need to be taken. In particular, it is very important that the entire system is protected against freezing temperatures and humidity.

Dosing system • Rinse the pump with fresh, lukewarm water for about 30 minutes. To do so, you can place the suction lances

into a pail filled with tap water and start a manual dosing (see Chapter 5 Performing a manual dosing). • Subsequently ensure that the system is fully disconnected from the power grid. • Loosen the dosing hose set to prevent permanent deformation.

Measuring system • Take the electrode out of the measurement cell and place it upright in the containers a frost-free location. The

three molar KCL solution in the containers protects the electrodes from drying out. Alternatively, the electrodes can also be stored in buffer solution or clear tap water.

• Close the electrode drill hole of the measurement cell with the supplied cover screw. • Let the water drain from the measurement chamber and measurement lines. Connect the valves of the

measuring water extractor and return.

Page 17 of 28

Manual dosing The parameter specifies in litres the dose amount of a manual dosing. In addition, the pH FUN shows the duration of the manual dosing (in minutes) which results from the respective dose amount (see also Chapter 5 Performing a manual dosing).

Dose amount Using the dose amount parameter, the amount of the pH-Minus (or pH-Plus) which the pH FUN doses into the pool water can be varied. In most cases, the standard setting "normal" delivers optimal results. Should the dosing achieved with this setting be generally too high or too low, a corresponding correction can take place:

Setting Description normal Standard setting low Dose amount is generally reduced by 30% compared to the standard setting ("normal"). high Dose amount is generally increased by 50% compared to the standard setting ("normal").

Min.dos.rate With increasing proximity of the pool water pH value to the pH setpoint, the pH FUN automatically reduces the dose rate, i.e. less and less pH-Minus (or pH-Plus) is dosed. However, this can lead to the setpoint not being reached completely. The minimum dosing rate of the pH FUN acts against this. It will never be fallen below as long as the setpoint was not yet reached. The standard setting should only then be modified when the pH value of the pool water either does not reach the desired setpoint or overshoots the desired setpoint. (see also Chapter 9.3 The pH value in the pool is not correct)

pH setpoint The parameter specifies the desired pH value in the pool water. A pH value in the rage of 7.0..7.4 is recommended for swimming pool water.

pH alarm limits Should the pH value of the pool water depart from the setpoint value due to a problem, the pH FUN triggers a measurement alarm. The alarm values are set as range around the current setpoint e.g. 7.20 ± 0.4 pH. The setpoint in this example lies at 7.2 pH, the lower alarm limit at 6.80 pH and the upper alarm limit at 7.60 pH.

Acoust. alarm Activation or deactivation of the acoustic alarm of the pH FUN.

Language You can switch the menu language of the pH FUN here.

Pool volume You can enter the volume of your swimming pool in m³ (cubic metres) here. The pH FUN automatically adapts the pH-Minus (or pH-Plus) dose amount to the entered pool volume (see also Chapter 7.2 Calculating the dosing rate).

Important: The pool volume must absolutely be entered correctly to ensure an optimal dosing and thus a proper control of the pH value by the pH FUN. Furthermore, there is the possibility, where necessary, to increase the dosing amount by input of a larger pool volume or to reduce the dosing amount by input of a smaller pool volume.

Dosing direction You can set the desired dosing direction here:

Setting Dosing direction

Pool care

product

Description

pH- pH-reducing pH-Minus In the most cases, the pH value of the pool fill water lies above the recommended range 7.0..7.4 pH, and the pool water generally tends to an increase of the pH value. The standard dosing of the pH FUN is therefore pH-reducing, with dosing of pH-Minus.

pH+ pH-increasing

pH-Plus In some cases the filling water or pool water tends to lower pH values. For this, the dosing direction of the pH FUN can be switched over to pH+ (pH -increasing). pH-Plus must then be dosed.

Danger warning: The pH regulation of the pH FUN can only work correctly if the dosing direction is set correctly and the appropriate pool care product is used. For the dosing direction pH-, you must use pH-Minus as pool care product; for the dosing direction pH+, you must use pH-Plus. If this combination is not observed, an overdosing can occur despite the comprehensive safety mechanisms of the pH FUN. In extreme cases, this can lead to health hazard.

Dosing alarm The pH FUN checks at regularly specified time intervals whether the pH value of the pool water has sufficiently approached the set setpoint. If this is not the case, there is probably a problem and the pH FUN blocks the dosing. A dosing alarm is triggered. You can set the time interval according to which the criteria for the dosing alarm are checked. The standard setting of 60 minutes delivers good results in most cases. If unnecessary or undesired dosing alarms occur or the dosing alarm does not activate as expected, the time interval can be adapted accordingly (see Chapter 9.1 The pH FUN reports an alarm).

Danger warning: By setting the time interval to 0 minutes, the dosing alarm is completely deactivated. Doing this will override an important safety mechanism of the pH FUN. With deactivated dosing alarm, under certain circumstances, an overdosing can occur which in the extreme case can also lead to health hazard. We therefore expressly advise you against deactivating the dosing alarm. The responsibility lies with the operator for a deactivation of the alarm.

4.4 Initial operation of the pH FUN The first time a factory-new pH FUN is switched on, a special initial operation menu is automatically run through which will lead you step-by-step through the most important basic settings. The menu tree in Chapter 4.2 The pH FUN menu will provide you with an overview of the initial operation menu. Perform the parameter settings in the individual steps of the initial operation menu according to the general mechanism as described in Chapter 4.1.2 Performing a parameter setting. If the initial operation is not run through completely until it reaches the normal view, the initial operation will be started again the next time the pH FUN is switched on. The execution of the initial operation is described under 2 Putting into operation

4.5 The energy-saving mode of the pH FUN After 15 minutes, the pH FUN will automatically switch to an energy-saving mode. The display illumination is switched off in this mode. All measurement and control functions of the pH FUN are, however, active without restriction in the energy-saving mode. The display illumination automatically switches on and blinks for alarms. You can exit the energy-saving mode at any time by pressing any button.

5 Performing a manual dosing

Danger warning: The dose amount or length of time of a manual dosing must be selected with care and expert knowledge. An overdosing, which in the extreme case can lead to a health hazard, could be the result. The setting of a suitable dose amount or length of time is the sole responsibility of the operator. To ascertain the appropriate manual dose amount, please see 5.1 Calculating the manual dosing.

In certain situations, e.g. after a new filling of the pool, it can make sense to specifically dose a larger amount of pH-Minus (or pH-Plus) into the pool water. The manual dosing mechanism exists for this purpose. During a manual dosing, the dosing pump runs for a limited time with full dosing rate (100%). The dose amount of a manual dosing and the resulting time duration can be set in the menu (0.1…4.0 litre, see Chapter 4.3.3 Setting options in the menu setting options in the menu). You can start a manual dosing from the normal view by switching the operating mode of the pH FUN to Man.- (or Man.+). The duration in time of the manual dosing is then counted down (in minutes) in the display:

7.40 pH

67min_ D-100%

After completion of the manual dosing, the pH FUN automatically jumps back to the previously valid operating mode "Auto" or "Off". You can abort a running manual dosing at any time by resetting the operating mode to "Auto" or "Off".

5.1 Calculating the manual dosing The following approximation formula can be used to calculate the appropriate pH-Minus dose amount: pH-Minus dose amount = Desired lowering of the pH value x Pool volume in m³ x 0.1 litres Example:

In a 40m³ pool, the pH value shall be reduced from 7.6 pH to 7.2 pH. The desired lowering of the pH value thus amounts to 0.4 The pH-Minus dose amount calculates to 0.4 x 40 x 0.1 litres = 1.6 litres. The dosing pump of the pH FUN has a dosing rate of approx. 0.9 litres/h. Thus, the time duration for the dosing of a specified dosing amount is calculated as follows: Dosing duration in min = Dose amount in litre x 60 / 0.9 For the dose amount of 1.6 litres from the above example, this thus results in a dosing duration of just under 107 minutes.

5.2 Safety functions for a manual dosing With a manual dosing as well, there are various safety functions active:

• The pH FUN will block the manual dosing for a missing flow signal (no flow through the measurement cell)

• The manual dosing is blocked by a level alarm (canister empty)

• A manual dosing in pH-reducing direction is limited by the lower alarm limit

• A manual dosing in pH-increasing direction is limited by the upper alarm limit

In contrast, the dosing alarm is not active with a manual dosing. For a precise description of the alarm and safety functions of the pH FUN, see Chapter 8 Alarms and safety functions.

6 Performing the pH7 calibration

Danger warning: The regular performing of a pH7 calibration is an important prerequisite for a correct measurement of the pH value and thus for the correct control and dosing function of the pH FUN. A missing or incorrect pH7 calibration can have as a result a pH value in the pool water that is too high or too low, which in the extreme case, can lead to a health hazard. It is therefore imperative that a pH7 calibration be performed with the initial operation as well as subsequently at least every 3 months. A new pH7 calibration must also be performed again after a replacement of the pH electrode. Moreover, the pH value in the pool water should be regularly tested using pH test strips or a Phenol Red colour test (commercially available).

For the pH7 calibration, you will require the pH7 buffer solution, which is included in the scope of supply of the pH FUN. Please follow exactly the following sequence step-by-step for the pH7 calibration:

1. In the normal view of the pH FUN, press the button (at least 2 seconds) to call up the menu.

2. A screen page for the pH7-Calib. appears immediately:

pH7-Calib. OK_

7.09 pH The currently measured pH value is displayed in this page, in the example 7.09 pH.

3. Stop the measurement water flow through the measurement cell by closing the appropriate shut-off valve. Open the container with the pH7 buffer solution.

4. Remove the plastic cover of the pH FUN measurement cell and carefully unscrew the pH electrode out of the measurement cell. Loosen the BNC connector of the electrode on the pH FUN device beforehand so that the electrode cable does not get twisted when unscrewing the electrode. Handle the electrode by its plastic shaft only.

5. Rinse the electrode in clean water and then dry it carefully using a soft cloth.

6. Now immerse the electrode in the container with the pH7 buffer solution. You should not sway the electrode but rather immerse it to the bottom of the container and hold it as still as possible.

7. Observe the displayed pH value on the pH FUN. After immersion in the pH7 buffer solution, it will usually change slowly. After approx. 1-2 minutes in the buffer solution, the display should stabilise again and only fluctuate by a maximum of 0.01..0.02 pH.

8. When the displayed pH value for the buffer solution has stabilised, press the button to perform the pH7 calibration.

9. The pH measured value on the pH FUN is corrected to 7.00 pH by the calibration. After the calibration, the value 7.00 pH should therefore appear in the display of the pH FUN, whereby slight fluctuations in the range of approx. 6.97...7.03 pH are normal and acceptable.

10. Now press the button again (at least 2 seconds) to return to the normal view of the pH FUN.

11. Remove the pH electrode from the buffer solution, rinse it in clean water and then dry it carefully using a soft cloth.

12. Screw the electrode back into the measurement cell again. Tighten the electrode firmly by hand. Ensure a secure sealing.

13. Now connect the BNC connector of the electrode to the pH FUN device again and attach the plastic covering of the pH FUN measurement cell again.

14. Start the measurement water flow through the measurement cell again by opening the appropriate shut-off valve.

If the pH7 calibration does not function, please observe the information in Chapter 9.5 The pH7 calibration does not work.


Page 21 of 28

7 Measurement and control of the pH value The pH FUN continuously measures the current pH value in the pool water and constantly adjusts it by automatic addition of pH-Minus (or pH-Plus) to the setpoint specified in the menu. The recommended pH value for swimming pool water lies in the range 7.0..7.4 pH. The pH FUN continually calculates the optimal dose amount or dosing rate in the respective situation.

7.1 Dosing rate and dosing cycle The pH-Minus (or pH-Plus) dosing occurs within a fixed cycle of 60 seconds length. Within this 60 second dose cycle, the dosing pump is switched on and off again depending on the dosing rate. The dosing rate is specified in % and states how long the dosing pump is switched on based on the 60 second dosing cycle:

Dosing rate Dosing cycle Switched-on time of the dosing pump

Switched-off time of the dosing pump

0% 0s 60s 5% 3s 57s 10% 6s 54s 25% 15s 45s 50% 30s 30s 75% 45s 15s 90% 54s 6s

100%

fixed 60s

60s 0s

7.2 Calculating the dosing rate The optimal dosing rate for the respective situation is continually recalculated by the pH FUN depending on the current pH value of the pool water, the desired setpoint and additional parameters. The following factors come into play when calculating the dosing rate:

Parameter Explanation Current pH value in the

pool water Desired

pH setpoint

The stronger the currently measured pH value of the pool water deviates from the set setpoint value, the higher the dosing rate will be i.e. the more pH-Minus (or pH-Plus) is dosed into the pool water. Since the dosing rate increases proportionally to the deviation between the current pH measured value and the pH setpoint, we call this a proportional regulation.

Pool volume The calculated dosing rate is proportionally adapted to the entered pool volume. With larger pools, the dosing rate is increased, with smaller pools, the dosing rate is reduced.

Dose amount low / normal / high

Using this setting, the dose amount / dosing ra te can be increased or reduced as needed. In the most cases, the standard setting of "normal" ensures a correct regulation of the pH value. In the "low" setting, the pH FUN reduces the dose amount / dosing rate compared to the "normal" setting by 30% usually. In the "high" setting, the pH FUN increases the dose amount / dosing rate compared to the "normal" setting by 50% usually.

Min.dos.rate (minimum dosing rate)

To ensure a reliable achievement of the setpoint, the pH FUN works with a minimum dosing rate (standard setting 5%), that is never fallen below provided the setpoint is not yet reached. The minimum dosing rate ensures that even when approaching the setpoint that sufficient pH-Minus (or pH-Plus) is dosed.


Page 22 of 28

8 Alarms and safety functions The wide range of safety functions and alarm mechanisms of the pH FUN ensure that possible problems are reliably detected and signalled early on.

8.1 The alarm view of the pH FUN As soon as the pH FUN has detected a possible problem, it signals this in the following way:

• The pH FUN automatically switches to the alarm view (see also 8.4), where possible problems and alarms are displayed. The entire display blinks additionally.

• Acoustic alarm, provided it is switched on in the menu (see 4.3.3 Setting options in the menu). In the normal view, the pH FUN signals pending alarms by blinking of the current pH value display. Using the buttons, you can switch back and forth between the normal view and the alarm view.

8.2 Acknowledging alarms Press any key to acknowledge the displayed alarms. This will stop the blinking of the display and the acoustic alarm (if activated).

8.3 Blocking dosing For safety reasons, the pH FUN blocks the dosing of pH-Minus (or pH-Plus) for the following events:

• Missing measurement water flow through the measurement cell

• During the power-on delay

• During a level alarm

• During a dosing alarm

Only when the reason for the blocking is no longer present will the pH FUN again enable the dosing. When dosing is blocked, the pH FUN always shows a dosing rate of 0% in the normal view.

8.4 Possible displays in the alarm view The following displays can appear in the alarm view:

Display Explanation

No alarms There are no alarms pending and the f low signal is present.

No flow No measurement water flow through the measurement cell (missing flow signal).

Delay Xmin A power-on delay is running after the switching on of the pH FUN or after an interruption of the measurement water flow. The pH FUN shows the remaining time of the power-on delay in minutes.

Upper alarm Upper threshold alarm. The current pH measured value lies above the upper alarm limit.

Lower alarm Lower threshold alarm. The current pH measured value lies below the lower alarm limit.

Level alarm The pH-Minus (or pH-Plus) canister is empty and must be replaced.

Dosing alarm The pH FUN has detected a dosing alarm since sufficient approaching of the pH value to the desired setpoint was reached.

Flow monitoring A measurement and regulation of the pH value is only possible if the pool circulation is running and pool water is continually flowing through the measurement water circuit. A flow sensor is installed in the measurement cell of the pH FUN for this reason.


Page 23 of 28

If the flow signal is missing, the pH FUN blocks the additional dosing of pH-Minus (or pH-Plus) to prevent a dosing into standing measurement water.

Power-on delay After switching on of the pH FUN, as well as after every interruption of the flow signal, a power-on delay of 5 minutes elapses before the pH FUN enables dosing again. This delay primarily serves for the stabilisation of the pH measurement water.

Upper and lower threshold alarm If the current pH measured value moves outside of the specified alarm limits (see 4.3.3 Setting options in the menu), the pH FUN will report an upper or lower threshold alarm. In this case, you should check whether there is a problem. The dosing in pH-reducing direction is NOT blocked by an upper threshold alarm, likewise the dosing in pH-increasing direction is NOT blocked by a lower threshold alarm.

Level alarm The suction lance of the pH FUN that is attached in the pH-Minus (or pH-Plus) canister, contains an empty sensor. If the pH FUN receives and empty signal, it signals a level alarm. The fill level of the canister in this case is no longer sufficient for an additional dosing; the dosing is blocked. Replace the empty canister. The pH FUN subsequently resumes with the dosing.

Dosing alarm If the current pH measured value deviates from the desired setpoint, the pH FUN will continually dose pH-Minus (or pH-Plus) in order to compensate for the deviation. In this case an approaching of the pH measured value to the setpoint is to be expected in the course of time. The pH FUN checks at specified intervals (see also 4.3.3 Setting options in the menu) whether the expected proximity to the setpoint has actually occurred. To do this, the pH FUN checks different criteria. If these proximity criteria are fulfilled, the dosing is continued. If the criteria are not fulfilled, the pH FUN reports a dosing alarm and blocks the additional dosing. In this case, there is most likely a problem or the current settings for the pool are unsuitable. You can learn about the possible problem causes and information on their remedy in Chapter 9 Possible problems and their remedy. The entire system should be inspected for possible problems in the event of a dosing alarm. The dosing alarm and the blocking of the dosing are ended when you manually confirm the dosing alarm by pressing any button.

9 Possible problems and their remedy

9.1 The pH FUN reports an alarm In the event of an alarm, the display of the pH FUN starts to blink and a signal tone is emitted in short intervals (provided the acoustic alarm is activated). Acknowledge the alarm by pressing any key. The blinking of the display and the signal tone are then ended.

Cause Remedy The pH FUN reports "No flow"

The pool circulation is not running. In this case, the "No flow" display is normal. It disappears as soon as the pool circulation is switched on again.

The pH FUN reports "No flow" despite running pool circulation

The measurement water circuit or the float of the flow sensor in the measurement cell is blocked.

Check the measurement water circuit and the float and remedy the blockage if necessary.

The pH FUN reports "Upper alarm" (for dosing of pH-Minus)

The measured pH value of the pool water is too high.

After a new or partial filing, the pH value of the pool water can lie above the upper alarm limit. The pH FUN automatically lowers the pH value in this case by addition of pH-Minus and in this way approaches the setpoint.

The pH FUN reports "Lower alarm" (for dosing of pH-Minus)

The measured pH value of the pool water is too low. An overdosing of pH-Minus may possibly have occurred.

Reduce the value of the "Min.dos.rate" parameter (see 4.3.3 Setting options in the menu) in 3% steps to reduce the dosing rate to the proximity of the setpoint. Additionally, you can change the "Dose amount" parameter from "normal" to "low" or from "high" to "normal" in order to generally decrease the dose amount.

The pH FUN reports "Upper alarm" (for dosing of pH-Plus)

The measured pH value of the pool water is too high. An overdosing of pH-Plus may possibly have occurred.

Reduce the value of the "Min.dos.rate" parameter (see 4.3.3 Setting options in the menu) in 3% steps to reduce the dosing rate to the proximity of the setpoint. Additionally, you can change the "Dose amount" parameter from "normal" to "low" or from "high" to "normal" in order to generally decrease the dose amount.

The pH FUN reports "Lower alarm" (for dosing of pH-Plus)

The measured pH value of the pool water is too low.

After a new or partial filing, the pH value of the pool water can lie below the lower alarm limit. The pH FUN automatically approaches the pH value to the setpoint by the addition of pH-Plus.

The pH FUN reports "Level alarm"

The pH-Minus (or pH-Plus) canister is empty.

Replace the empty canister with a new one.

The pH FUN reports "Dosing alarm"

The pH FUN does not achieve the desired pH setpoint in the water despite the dosing of pH-Minus (or pH-Plus).

Acknowledge the dosing alarm by pressing any button. The pH FUN resumes with the dosing and thus adjusts the pH value in the water to the setpoint again.

The pH FUN continues to report a "Dosing alarm"

Despite the dosing of pH-Minus (or pH-Plus), the pH FUN is again not able to bring the pH value of the pool water close to the desired setpoint.

The dosing rate may possibly not be sufficient enough to achieve sufficient proximity to the setpoint. In this case, increase the dosing rate as follows: • Increase the value of the "Min.dos.rate" parameter (see 4.3.3 Setting options in the menu) in 3% steps to increase the dosing rate specifically near the proximity of the setpoint. • Change the "Dose amount" parameter from "normal" to "high" or from "low" to "normal" in order to generally increase the dose amount. You can also increase the dosing alarm response time. To do this, double the set value of the "Dosing alarm" parameter, e.g. from 60 min to 120 min.


Page 25 of 28

9.2 The pH FUN does not display the correct pH value Cause Remedy The displayed pH value on the pH FUN deviates greatly from the check measurement using colour strips or Phenol Red tablets.

• The check measurement may possibly be incorrect.

• A new pH7 calibration of the pH FUN may possibly be necessary or even a replacement of the pH electrode under certain circumstances.

• The pH measurement of the pH FUN may be skewed due to an external voltage on the pool water.

• Repeat the check measurement following the associated instructions precisely. If necessary, use a different method for the check measurement. We recommend the use of Phenol Red tablets.

• Perform a pH7 calibration and observe the sequence described in Chapter 6 precisely.

• Check the earthing of the measurement water circuit.

You will achieve optimum results through two-sided earthing both in the measurement water feed as well as in the measurement water return.

9.3 The pH value in the pool is not correct If the displayed pH value on the pH FUN deviates greatly from the check measurement using colour strips or Phenol Red tables, please follow the instructions in Chapter 9.2.

Cause Remedy The pH value in the pool lies above the setpoint

The pH FUN requires more time to adapt the pH value of the pool water to the set setpoint.

Observe whether the pH value gets closer to the setpoint. If it does not get sufficiently close, the pH FUN triggers a dosing alarm. In this case, please observe the appropriate instructions in Chapter 9.1.

The pH value in the pool overshoots the set setpoint

An overdosing of pH-Minus has occurred. The dosing rate of the pH FUN is too high for the pool, particularly in the area of the setpoint.

Reduce the value of the "Min.dos.rate" parameter (see 4.3.3 Setting options in the menu) in 3% steps to reduce the dosing rate to the proximity of the setpoint and thus prevent an overdosing. Additionally, you can change the "Dose amount" parameter from "normal" to "low" or from "high" to "normal" in order to generally decrease the dose amount.

9.4 The dosing pump is not running Cause Remedy The pH FUN shows a dosing rate of 0% in the normal view and the dosing pump is not running.

The pH value of the pool water has the reached the setpoint (or lies below the setpoint).

In this case, no additional pH-Minus dosing is required. This is thus correct and the dosing pump does not run.

The pH FUN shows a dosing rate of 0% in the normal view and the dosing pump is not running. But the displayed pH value lies above the setpoint.

The dosing of the pH FUN is blocked. The following causes are possible for this: • No flow • Power-on delay • Level alarm • Dosing alarm

Switch to the alarm view of the pH FUN to determine the cause of the blocking. Please observe the information about the different alarms in Chapter 9.1 to remedy the blocking.

The pH FUN shows a dosing rate of 0% in the normal view but the dosing pump is not running.

It is normal that the dosing pump is switched on and off in intervals. Depending on the current dosing rate, it may only run for several seconds per minute under certain conditions. (see also Chapter 7.1) If the dosing pump does not run at all over multiple minutes, the fuse for the pump may possibly be defective.

Replace the fuse for the dosing pump and contact BAYROL service if necessary.


Page 26 of 28

9.5 The pH7 calibration does not work For the pH7 calibration, the pH FUN allows a maximum deviation of ±1pH which is compensated by the calibration. If the calculated deviation is greater than ±1pH, there is a problem present. In this case, the pH FUN does not perform the pH7 calibration. The error message disappears again by pressing any button.

Cause Remedy The pH FUN shows "Error! Calibration invalid."

• The pH electrode is defective or too worn out. It no longer supplies correct measured values.

• The pH7 buffer solution may possibly be contaminated and shows an incorrect pH value.

• The correct sequence for the pH7 calibration may not have been adhered to precisely. The pH measured value may possibly have not yet sufficiently stabilised in the pH7 buffer solution

• Please absolutely replace the pH electrode.

• Use a new pH7 buffer solution and perform the pH7 calibration again.

• Perform the pH7 calibration again and proceed step-by-step exactly as described in 6 Performing the pH7 calib.

9.6 The display of the pH FUN is dark Cause Remedy The display of the pH FUN is dark

The energy-saving mode is activated (see 4.5).

Press any key to end the energy-saving mode of the pH FUN.
