1.0 HOW THE CALOREX DELTA SYSTEM WORKSThe Calorex 'DELTA' range consists of 9 models 1, 2, 4, 6, 8, 10, 12, 14, 16.The model number increases in relation to the recirculated air flow, from 2500m³/h for a Delta 1to 12000m³/h for a Delta 16.All models have the facility to exhaust a percentage of the recirculating air and introduce aslightly lesser amount of fresh air. (Slight differential creates a negative pressure on pool hall tolocalise pool environment and protect the building fabric).All models are fitted with a fully controlled air heater battery and pool water heatexchanger. These are designed to operate with LPHW at 80°C/60ºC provided by a standardboiler. Provision is made for this boiler to be initiated by the 'DELTA' controller. All models haveair and water heat exchangers deriving energy from the refrigeration/dehumidification process.These are also fully controlled with priority given to water.The range divides into two specification levels between model 2 and 4 so that models 1 and 2are lesser specified than models 4 upwards.The main difference being that models 1 and 2 are not fitted with a heat exchanger in theexhaust air stream so do not mechanically reject heat into the atmosphere but rely only on freshair heat rejection. The models 4 upwards however, have fresh air and mechanical rejectiongiving them air conditioning capacity.

THE CALOREX DELTA RANGEFEATURESAll DELTA models have two fans, a main recirculating fan and a smaller exhaust fan.Models 1 and 2 use direct drive fans but all larger models have belt driven fans,all models havemotor driven variable dampers on the exhaust and fresh air dampers.Models 1 and 2 have circular ducting spigots, 12" diameter for fresh air inlet and exhaust and 18"diameter on air OFF for all configurations of outlet.Models 4 to 12 have rectangular duct spigots for fresh air, exhaust air and "pool air off" for allconfigurations other than downdraught. In this case the unit is supplied with an extra spigotflange which is bolted to the floor ducting and is connected to the fan outlet spigot by a flexible20" diameter connector which, along with the securing straps, floor spigot and flexible ducting,are supplied with the machine, with the exception of model 14 upwards that has a sealedchamber from the machine to the floor.The power to models 1 to 12 in the DELTA range is fed in via a connecting box on the top of theunit. This is an aluminium box with 2 holes for cable glands already cut. Models 14 upwards arefed via the main electrical box.Delta 14 and 16 have extra features: fitted with two speed fans, when there is not a demand forair heating, dehumidification or air conditioning, the fans automatically switch to the lower speedthus saving energy; can be supplied with an air quality sensor.
CONTROL PANEL. All ModelsDelta models 1 and 2 have no refrigerated air conditioning facility, there is only one indicator toindicate a demand for air heating, whereas there are two indicator lights for AIR on models 4upwards, to indicate a demand for heating and cooling. The panel has the following equipment:1. Relative Humidity Controller: with red indicator light below it showing dehumidification taking place.2. Air Temperature Controller: with red indicator light to show heating or cooling taking place.3. Water Temperature Controller: with red indicator light to show heating taking place .4. Damper Control Switch: enabling damper to be set to automatic operation (normal) or to befully opened or fully closed manually. The MIN and MAX positions are for use by experiencedoperators to allow, for example, quick start up without air induction and quick ventilation shouldan emergency necessitate this.5. Power Switch: to switch the machine ON and OFF. With the unit switched OFF, onlythe mains indicator light and the clock are energised .6. A time clock to control the "occupied/unoccupied" timings with battery 'back up' andmanual override. This clock is NOT for turning the Delta unit on and off.7. A row of indicator lights showing:Mains ON, Fault, Defrost, Automatic OperationThe control panel is protected by a tinted plastic cover enabling the controls to be viewed withoutbeing opened.Behind the right hand electrical control box panel on all Delta machines are two manually setthermostats, one for ambient air temperature monitoring, one for setting the unoccupied pool hallair temperature. On Deltas 14 and 16 stage 1 of the air temperature controller is used for nightset back.In the same area are the control circuit and motor protection units, these are in the form of circuitbreakers, as a result fuses are not required in the DELTA range with the attendant advantages.On all models the control circuit is protected by a single circuit breaker (MCB). On single phasemachines all motors are also protected by MCBsOn three phase machines models 1 and 2, the two fans are single phase and are protected byMCBs whilst the compressor is protected by a three phase motor rated circuit breaker. OnDeltas 12 to 16 the compressor is also protected by a phase rotation relay.8. Delta 14 and Delta 16 are fitted with an economy switch allowing the user to select betweenwater heating only or the full functions of the machine.
page 5
OPERATIONWhen the DELTA is connected to the mains supply via an isolator, and the isolator is energised,the MAINS light on the panel will light indicating mains ON, and the clock will commenceoperating. The clock has a battery reserve fitted which when charged has an operating time of100 hours so that isolating the DELTA unit for short periods will not change the clock setting.The DELTA unit is switched on to normal operation by an ON(I)/OFF(0) switch on the controlpanel.Providing that the controls are set to the correct parameters, nominally 60% RH, 28°C airtemperature and 26°C water temperature and the fresh air switch is set to it's middle position(AUTO), then the machine will operate automatically. The 'unoccupied' temperature is set on thethermostat mounted inside the electrical control panel and will be switched at the time set on theclock.(Factory setting 24ºC)As the unit operates, the indicator lights will indicate the state of the control conditions, with thelights indicating dehumidification, heat to air and heat to water and on models 4, 6, 8, 10, 12, 14and 16 in the air conditioning mode, heat from air to atmosphere.
On models 4, 6, 8, 10, 12, 14 and 16 there are two indicator lights to the right hand side of the airtemperature controller, one for heat, one for cooling, also an air cooling switch is fitted to allowthe air conditioning feature to be turned off.
On models 1 and 2 which have no refrigerated air conditioning capacity there is only one airindicator lamp and that is for heating.
At the bottom of the panel are four further lights:Red for Mains ON (showing that the isolator is made and the unit is energised).Amber for Fault (high or low refrigerant pressure trip).Clear for Defrost.Green to indicate automatic operation.
PARAMETER CONTROLLERSEach parameter; Relative Humidity, Water Temp and Air Temp is sensed within the machineand the signal is taken to the relevant controller.With the exception of Deltas 14 and 16 air controller, each temperature controller has twoswitching channels:K1 (OUT1) which is set from the front panel K2 (OUT2) which is factory pre-set. The aircontroller on Delta 14 and Delta 16 has a three switching channels, OUT1 which controls theunoccupied periods, OUT2 which is set from the front panel and OUT3 which is factory preset.Each channel has a switching differential which is also pre-set in the factory. These should notbe tampered with.When the re-settable channels K1 (OUT1) or OUT2 are adjusted all other settings anddifferentials automatically follow at the correct relationship.OPERATIONTIMECLOCKThe time clock setting determines the OCCUPIED/UNOCCUPIED periods and is set tomatch the operators' requirements regarding times when the pool is covered or uncovered.There are two settings as mentioned OCCUPIED or daytime (uncovered), and UNOCCUPIEDor night time (covered).The most obvious action in this change is to lower the pool hall air temperature to a determinedtemperature to conserve air heating energy. This lowering of temperature is allowable becauseof the quiescent, and hopefully covered, condition of the pool. The UNOCCUPIED pool hall airtemperature is controlled by a dedicated thermostat mounted within the control panel. Note thaton Delta 14 and Delta 16 there is a 60 minute time delay on water heating when in theunoccupied mode.
page 6
DAMPER CONTROL SWITCHOn the front control panel is a 3 position switch which controls the inlet/exhaust air dampers.It's centre position is AUTO with a MIN and MAX either side.In OCCUPIED operation AUTO will allow the units control system to drive the damper motors toachieve the optimum condition for operation, but provision is made to manually drive the damp-ers to MAX or MIN.In UNOCCUPIED operation the AUTO setting will drive the dampers to MIN as will the MIN set-ting, however, if the switch is set to MAX the dampers will stay at MAX until the switch ischanged, regardless of clock setting. An optional air quality sensor can be fitted in Delta 14 andDelta 16. This also opens the dampers to maximum if the air quality is not acceptable.
CONTROLThe unit is automatically controlled by reference to three parameters, each one having adedicated controller mounted in the control panel.
On Deltas 1-12 each controller has one user adjustable set point with a 2nd switch point presetin relation to it. On Delta 14 and 16 the air stat has two adjustable set points with a 3rd switchpoint preset in relation to it.For example:The user adjustable RH set point controls the ON-OFF point of the dehumidification compressordirectly. 2.5% RH above this set point, the fresh /exhaust air dampers are opened by the secondchannel.The user adjustable air temperature set point controls the ON-OFF point for the LPHW heaterbattery directly, and, indirectly controls the "air conditioning" mode ON-OFF 2°C above the setpoint.The user adjustable water temperature set point controls the dehumidification driven waterheating condenser directly and, indirectly 0.2°C below the set point, controls the LPHW waterheater calorifier.
OCCUPIED AND UNOCCUPIED DIFFERENCES.The time clock determines the OCCUPIED and UNOCCUPIED periods according to its setting.The general operational difference is as follows:The time clock has a set of contacts which are energised during occupied periods.These contacts energise in turn the AS2 or AS3 (air conditioning) contacts on the airtemperature thermostat and a relay which deselects the UNOCCUPIED thermostat, selects theOCCUPIED thermostat, and selects full automatic control for the dampers.In essence the unit operates in all modes in OCCUPIED condition. In UNOCCUPIED condition itoperates similarly with the exceptions as follows:a) No refrigerated air conditioning models (4 upwards only)b) Pool hall air temperature lowered to the setting of the UNOCCUPIED thermostat. Delta 14 and16 setting of AS1c) Fresh/exhaust air dampers (if fitted) driven to MIN when 3 position switch is set to AUTO orMIN but stay on MAX when switch left on MAX, unless air quality is poor as detected by optionalair quality sensor which will open dampers to max on Delta 14 and Delta 16.

WHAT IS IT FOR?
The indoor swimming pool is a great source of pleasure to it’suser and provides enjoyment and exercise throughout the
year. Whether the pool is privately owned and used by familyand friends or as part of a commercial venture in a club or
hotel, the owner needs to be sure that the expensive structureis protected for the future and that the many economy
measures available are at his disposal to keep running costs toa minimum. So how do you best combine the provision for
maximum comfort with the assurance of economy, efficiencyand reliabiliy? The Calorex DELTA system is the answer.
DELTA operating on maximum dehumidification of pool airwith full heat recovery to pool water and air. Available energyis removed from exhaust air stream. Supplimentary heat ifrequired,supplied by LPHW (water to air).
DELTA operating on light dehumidification with full heatrecovery and reduced fresh air stream-control systemautomatically selects correct operating mode and damperposition. LPHW heat available when required.
Air Temperature set back control is incorporated as standard inall Delta units and is controlled by a time clock. Pool hall air isdropped to a lower temperature for maximum economy. Airrecirculation is maintained, dampers allow low fresh air flow.

2.3 PLUMBING
a) The Calorex ‘DELTA’ must be connected after the filter in the return pipe to the pool. If an existing heateris being retained, then the ‘DELTA’ should be connected upstream of the existing heater (see followingschematics).b) Calorex ‘DELTA’ units 1 to 12 have plastic stubs 1½” dia for connecting (solvent weld) the pool water inletand outlet. Delta 14 and Delta 16 have 1½” BSPM threaded plastic connectors.c) Suitable breakable couplings, isolation, and drain down valves should be installed in the pool water inlet/outlet pipes local to the ‘DELTA’ unit.d) The heat exchanger in the ‘DELTA’ unit will on small pools, take the full flow rate of the recirculationsystem. On larger pools a bypass or separate auxiliary pump may be necessary. This method can also beused to reduce energy consumption, by the installation of a two speed or auxiliary pump by-passing themain pump/filter to satisfy pool water heating and dehumidification without the need for the main pump to berunning. Further savings on both the above methods can be made by utilizing the standard feature on all‘DELTA’ units to control the main or auxiliary pumps (see section 2.4 electrical wiring).e) When the pipe work installation is complete the circulating pump(s) should be switched on and thesystem checked for leaks. Also check the filter gauge to see that there is not excessive back pressure.f) A flow meter should be fitted (or pressure gauges).
2.3.2) CONDENSATE DRAINa) The condensate drip tray at the base of the ‘DELTA’ unit collects the water removed by thedehumidification process. It is therefore necessary to ensure that the ‘DELTA’ unit is placed on a level plinthso that the condensate can run away and not overflow the edges of the drip tray inside the machine.b) All ‘DELTA’ units have a ¾” BSPM threaded condensate drain connection. The drain pipe should be runaway with the adequate fall to waste i.e. ½” per foot min. DO NOT fit a trap as it is a standard fitting insidethe unit. An air break or tun dish should be incorporated to prevent back flow of foul water and smells seeFig 3.1.
2.3.3) L.P.H.W. WATER PLUMBINGa) Calorex ‘DELTA’ 1/2/4/6/8 units have 28mm copper stubs whilst models 10 and 12 have 35mm stubs forconnecting (compression or solder) the boiler water flow and return. Models 14 upwards have 1½” BSPMthreaded connections.b) Suitable breakable couplings, isolation and drain down valves should be installed in the boiler waterflow/return pipes local to the ‘DELTA’ unit.c) A mixing valve and/or bypass may be required to maintain a minimum boiler return temperature and/orkeep a constant load to the boiler pump. Refer to the boiler manufacturers instructions before designingthe pipework system.d) If boiler and water pump is not controlled by ‘DELTA’’ then a boiler bypass will be required.e) A flow meter should be fitted (or pressure gauges).
2.3.4) IMPORTANT GENERAL POINTSa) Do not route water pipes across service access panels or Air inlet/outlet.b) The water circuits to and from the ‘DELTA’ units should be capable of maintaining within the specifiedlimits the water flow required. (see section 4, Data Sheet)c) All pipework must be adequately supported with allowance for expansion and contraction especiallywith regard to the plastic pipework.d) It is recommended that when installing water systems the last connections to be made should beadjacent to the ‘DELTA unit to avoid undue stresses on the unit connections.e) All pool Purifying Devices and Chemical Injection Systems must be fitted down stream of the DELTAunit with a non-return valve to prevent concentrated chemicals back feeding into the heat exchangers.The practice of dosing chemicals direct into the Skimmer Basket which results in concentrated corrosiveliquids passing over vulnerable metal components must not be allowed.f) Water quality must be maintained not only relating to solids, etc. but for pH between 7.4± 0.4, (and ifpool water is saline at a maximum concentration of 3% wt/wt). See section 6, Warranty Exclusions fortotal list of water quality limits.
2.3.1) POOL WATER
page 13
2.3.5 DETERMINING WATER FLOW
a) Flow Meter Method (see fig 3)Ensure isolation valves 'A' and 'B' and bypass valve 'C' are fully open. Slowly close downbypass valve 'C' until correct flow rate (see Data Sheet page 23) is shown on the flow meter.Remove handle and lock off valve 'C'.
b) Differential Pressure Method (see fig 3)By simply installing two filter pressure indicating gauges, one each on the inlet and outlet of theheat pump, and a locking type gate bypass valve in the bypass line, the flow rate through theheat pump can be accurately determined by the difference in the readings of the gauges. Thispressure drop is proportional to flow.Flow rate should be set at the maximum differential with a clean filter if fitted. This differentialpressure will drop as the filter becomes dirty. Provided the filter is cleaned before the minimumdifferential is reached (which would normally be the case with a well managed system) then noproblems should be encountered.
Setting up the differentialWhen installation is complete, the procedure for setting the flow rate through the heat pumpusing two gauges is as follows:
1. With the heat pump switched off ensure isolation valves 'A', 'B' and bypass valve 'C' are fullyopen.
2. Note the System Pressure on both gauges - they should read the same, but due to manufac-turing tolerances they may be different.
3. Switch on water circulating pump.
For example; with a water System Pressure of 5mhd the gauge on the inlet may read 5 and theoutlet gauge 5.5 therefore there is a STATIC ERROR DIFFERENCE of 0.5mhd.
4. Gradually close the bypass valve 'C' until there is a difference in pressure between the twogauges. It will be noted that the INLET gauge goes up in pressure.
EXAMPLEPump off Pump onBypass valve fully open After adjusting bypass valvegauge pressure is gauge pressure is
INLET 5.0 Static Head 6.7OUTLET 5.5 Static Head 4.0STATIC ERROR DIFFERENCE 0.5 2.7
Therefore pressure difference is 2.7+0.5=3.2mhd
5. Lock the bypass valve, or render it tamper proof, when correct setting is achieved.

2.4 ELECTRICAL INSTALLATION
2.4.1 Electrical Safety – It is important to ensure that all aspects of the installation complywith the latest I.E.E (16th) Regulations. Normally as the machine would be encom-passed within a plant room and providing the door is lockable, special regulations laidout in Chapter 6 of the rules do not apply. It is also important to ensure that any remotedevices which terminate within the pool hall are of the type and voltage as specified inthe I.E.E Regulations Chapter 6.
2.4.2 Protected Supply – Whilst not mandatory, Calorex recommend that an R.C.C.B isalways fitted or that the supply is to local electricity authority recommendations, andthat all ducting is bonded in in accordance with these regulations.
The supply to the machine should incorporate fuses or motor rated circuit breakers(Type GU, FAZC) to specified rating, (see Data Sheet). H.R.C fuses are recom-mended. An isolator must be fitted within clear view and not more than 2 meters away.The isolator must have a minimum 3mm air gap in the off position.
All units must be correctly earthed/grounded. An earth leakage trip of the currentoperating type (30mA) is recommended to be fitted to all pool electrics.
2.4.3 Inconsistent Electrical Supply – The following limits of operation must not be ex-ceeded if Calorex machines are to be guaranteed either in performance or warrantyterms:-
Voltage Minimum MaximumSingle phase machines 207v 253vThree phase machines 360v 440vFrequency 47.5hz 52.5hz
N.B The voltage must be measured at the heat pump mains terminals with all the fans/compres-sors running at the rated load condition.
2.4.1 Correct Cable Sizing – The cable supplying electricity toa machine with a given load must increase in crosssectional area (C.S.A) as the length increases in order thatthe voltage drop within the cable does not exceedrecommended limits. Cable sizing should be calculatedby an approved electrician with due consideration toI.E.E and local codes of practice.
NOTE: Delta 12, Delta14, and Delta 16 units are fitted with phase protection and will not run if phases are connected incorrectly.

NOTE 1. REMOTE OCCUPIED/UNOCCUPIED
These contacts are to enable the set back air temperature to be remotely overridden.There is a 12 Volt output from these terminals and closing a remote switch will enable the unit to regain thenormal operating air temperature for when the pool is in use.This can be done via a voltage free pool cover switch or some other form of voltage free switch.If this facility is used, the time clock on the control panel of the unit should be set to the "unoccupied" (II or0) position.If this facility is not to be used then these terminals can be ignored.
NOTE 2. POOL PUMP START SIGNAL
These are voltage free contacts rated at 2 Amp at 230 Volt.If the pool water pump is to be run via a time clock then these connections should go across the switchingcontacts of the clock to ensure that if dehumidification demand occurs the pool water pump will start.The pool water pump will exceed the rated curent of these contacts therefore a contactor/relay should beused to take the load of the pump. The switching action of the time clock should energise the contactor/relay coil.If the pool water pump is to be run continuously these contacts can be ignored.
NOTE 3. BOILER PUMP/GO SIGNAL
These are voltage free contacts rated at 2 Amp at 230 Volt.If the low pressure hot water supply to unit is to be governed by the unit then these contacts should beutilised to bring water to the unit via the boiler, motorised valve, boiler pump etc.This is dependant on how the low pressure hot water supply to the unit has been designed.If the supply of low pressure hot water to the unit is not dependent on a signal from the unit these contactscan be ignored.

3.2 CONTROL CONSOLE AND SETTINGSa) Time Clock Will require initial setting to time of day followed by setting up for switching
periods occupied/unoccupied (see section 3.5.1)b) Power Switch Should be switched to ' I ' (ON) to turn on the Delta unit . Note that on the off 'O'
(OFF) position the Delta unit is still powered up and the machine should beisolated at the mains supply before removing any service panels.
c) Fresh Air Switch AUTO' position will allow the dampers to be controlled as required by the controlcircuit of the Delta unit.'MIN' position will override the Delta control and keep the dampers at minimumfresh air. Typically this feature would be used on start up, until the pool water andair reach the desired settings.
d) Air Cooling Switch Should be switched to 'I' (ON) to provide air conditioning when required .When switched 'O' (OFF) no air conditioning will be allowed.NOTE. Air damperswill still be controlled automatically irrespective of air cooling switch position.
e) Economy Switch This switch enables the user to select either water heating only or the fullDeltas 14 and 16 only. functions of the machine. (Please note that in economy mode there is a 60
minute time delay when water heating is required).
SETTING THE DIGITAL STATSIMPORTANT NOTE: We strongly recommend that once the control panel digital stats are programmed to theoptimum settings, that they are left to their own devices and not tampered with unnecessarily. Adjustment ofthe stat settings outside of the original parameters used to select the equipment may result in failure of theunit to achieve the required pool conditions or create inefficient operation.The digital stats for controlling Water Temperature, Humidity on Deltas 1 - 16 (and Air Temperature on Deltas1 - 12) Set Points (desired temperature/humidity) can be changed by following these instructions:* With current reading displayed press ‘P’ button once and release. ‘SP1’ (Set Point) and set point valuee.g.’60’ will be displayed alternately.* Press the or button to adjust the stat to the required set point. Press P to confirm change. Displaywill return to room value.NOTE: If anything else shows on display, leave alone for about 1 minute, until display returns to normal.
The digital stat for controlling Air on Deltas 14 and 16 can be changed as follows:To program the Set Point, Press P button once and release it. SP1 (Set Point) and set point value e.g. 28will be displayed alternately. Press P again, AL1 and AL1 value(-4.5) will be dislayed alternately. This is thedifference between the Set Point and AL1 plus HSEt. e.g. 28-4.5+0.5=24ºC (Night Set Back temperature)SP1 and AL1 can be changed in the same way as described for Humidity and Water. For all tecnologicparameter settings see pages 29 - 31.f) Humidity Control Should be set at the desired maximum relative humidity in the pool hall
(typically 60 %).g) Water Temp Control Should be set at the desired water temperature required in pool (Typically 26ºC)h) Air Temp Control Should be set at the desired air temperature required in pool hall (Typically 28ºC
but always 2ºC above pool water temperature).
Setting the alternative Stork Stats (unsuitable for Air stat on Deltas 14 and 16)Set by holding down the SET or P button and raising or lowering the digital display by pushing the orsymbol buttons to show the required setting. For parameter settings see page 28Do not change the diff Factory Settings. Humidity 5%, Air 2ºC, Water 0.1ºC.
i) Set Back Air Temp Located behind right hand electrical control panel and preset by commissioningThermostat engineer to required set back or unoccupied temperature (Typically 24ºC).
Delta 1-12 only. This feature is included in the Air Temp Controller on Delta 14 andDelta 16.
j) External Ambient Located behind right hand electrical control panel and preset by commissioningThermostat engineer to required temperature below which the dampers will not open to
maximum on ‘AUTO’ (for humidity control) unless there is a demand for airconditioning (Typically set to 15ºC).

a) Dehumidification Light - Indicates that there is a demand for the Delta unit to dehumidify.
b) Air Heating Light -Indicates that there is a demand for the Delta unit to heat the pool hall air.
c) Air Cooling Light -Indicates a demand for the Delta unit to cool the pool air. NOTE:This feature is not found on Delta models DT1/DT2 , and can be de -selected on DT4/6/8/10/12/14/16 by "Air Cooling Switch" .
d) Water Heating Light -Indicates that there is a demand for the Delta to heat the pool water.
e) Mains Light -Indicates that there is a power supply on to the Delta unit.
f) Fault Light -Check that the pool hall air flow and the pool water flow through the Delta unit are within specified limits. Check contactor overloads, MCB's and soft start overload (if fitted) and push all to reset. If fault light stays on call for service check .
g) Defrost Light -Indicates that the Delta unit is temporarily defrosting one or both of the evaporators to ensure efficient operation.
h) Auto light -Indicates that the Fresh Air Switch is set to 'Auto' see above.
a) Is the building finished in accordance with the original plans and specification?
b) Is the plenum chamber and all the duct work insulated? Special attention should be made to theinsulation of the Exhaust Air ducting and Fresh Air inlet ducting to prevent condensation problems.
c) Are there any significant draughts in the pool hall or plant room (plenum installation) through poorlyfitting doors, windows , pipe ducts, etc? This will let in unwanted Ambient Air raising the heating dutyrequired.
d) Is Fresh Air suction and Exhaust Air discharge ducting perfectly sealed from plant room .
NOTE: (c) and (d) above should be checked by measuring plant room and pool hall air temperatures.If the plant room is acting as a plenum chamber both temperatures should correspond. If the plant roomair temperature is lower, then ambient air is leaking in. This leak should be located and rectified.
e) Are the Fresh Air inlet and Exhaust Air outlet free from obstructions, i.e .undersized grilles,objects in path of Exhaust Air deflecting it back to the fresh air inlet, etc.
f) On three phase machines check that the fans are running in the correct direction. Note that wrongrotation gives a reduced air flow but not a reversed air flow. Correct the rotation by reversing two of thesupply phases to the Delta unit .
g) Are Set Back and Ambient Air thermostats set correctly on Deltas 1-12?
h) Is Time Clock set correctly ?
i ) Is Start Up, Fresh Air Min feature required and if so is customer aware of when to switch machineback to Auto?
j) Is Pool Water flow rate set correctly as specified?
k) Is Boiler Water (L.P.H.W) flow rate as specified?
l) Are Air Flows balanced and at design as specified?

NIGHT TIME POOL PUMP RUN PERIOD
TYPICAL DAY TIME SAMPLING PERIOD
OPTIONAL AIR QUALITY SENSORLocated next to the electric box on Delta 14 and Delta 16 and preset by the commissioning engineer to therequired level.The exhaust dampers are driven to maximum if the air quality drops below the set level at any time.The position of the shorting plug on the sensor controls the quality of the air and should be set to the -position for adequate air quality with minimum energy consumption.When the shorting plug is in the mid position a good air quality level is achieved giving optimum energyconsumption.When the shorting plug is in the + position a very good air quality level is achieved at the expense ofincreased energy consumption.In the interests of safety the position of the shorting plug can only be changed by an electriciandue to a danger of electric shock from touching mains carrying wires or parts.The air quality sensor adapts itself to the local air quality. The sensor takes about one minute to reach itsoperating temperature, but takes about two days to stabilize. For this reason the power supply to thecontroller should not be interrupted.
3.5.2 EXTERNAL CUSTOMER SWIMMING POOL PUMP/FILTERTIME CLOCK
If pool pump is used during cheap tariff (ie economy 7), the customer’s pool pump/filter time clock(not part of Delta unit) should be set up as required but with approximately two fifteen minute samplingperiods to allow the Delta unit to maintain pool water temperature.
If the pool water temperature is not satisfied during the sampling periods the Delta unit will continue to heatthe pool water and run the customer’s pool pump until the correct water temperature is achieved. (Poolwater Set Point factory set at 26ºC).
PLEASE NOTE: THE DELTA UNIT MAY OVERRIDE THE TIMECLOCK.
