► Restore earthing connections to their original con-dition after completion of the work.


Risk of injury from moving parts ► Switch device on only with air flow baffles fitted.

Injuries and environmental damage due to refrigerantThe unit contains harmful and environmentally dan-gerous refrigerant. If refrigerant leaks out of the unit:

1. Switch off the unit.

2. Notify authorised after sales service.

2.5 Disposal

Environmentally hazardous mediaImproper disposal of environmentally hazardous me-dia (refrigerant) will damage the environment:

► Collect media safely.

► Dispose of the media in an environmentally sound manner in accordance with to the local regula-tions.

2.6 Avoid material damageThe ambient air at the heat pump’s installation site, as well as the air drawn in as a heat source, must not contain any corrosive components!

Constituents such as

● Ammonia

● Sulphur

● Chlorine

● Salt

● Sewage gases, flue gases

can cause damage to the heat pump, which can even result in the complete failure/total loss of the heat pump.

Decommissioning/draining the heatingIf the system/heat pump is decommissioned or drained after already being filled, it must be ensured that the condenser and any heat exchangers have been drained completely for the event of freezing temper-atures. Residual water in heat exchangers and con-densers can result in damage to the components.

► Completely drain the system and the condenser, and open vent valves.

► Blow them clear with compressed air, if required.

Improper actionRequirements for minimum scale and corrosion dam-age in hot water heating systems:

● Professional planning and commissioning

● Closed system with regard to corrosion

● Integration of an adequately dimensioned pres-sure maintenance

● Use of demineralised heating water (VE water) or water corresponding to the VDI 2035 norm

● Regular servicing and maintenance

If a system is not planned, commissioned and operat-ed in accordance with the given requirements, there will be a risk of the following damage and malfunc-tions:

● Malfunctions and failure of components, e.g. pumps, valves

● Internal and external leaks, e.g. at heat exchangers

● Reduction in cross-section and blockages in com-ponents, e.g. heat exchangers, pipes, pumps

● Material fatigue

● Gas bubble and gas cushion development (cavi-tation)

● Negative effect on heat transfer, e.g. due to for-mation of deposits, and associated noises, e.g. boiling noises, flow noises

► Observe the information in this operating manual for all work on and with the unit.

Unsuitable quality of the water for filling up and replenishing the heating circuitThe efficiency of the system and the service life of the heat generator and the heating components depend decisively on the quality of the heating water.

If the system is filled with untreated drinking water, cal-cium deposits will form as scale. Lime scale deposits accumulate on the heat transfer surfaces of the heat-ing. The efficiency is reduced and energy costs in-crease. In extreme cases, the heat exchangers will be damaged.

► Fill the system with deionised heating water (VE water) or with water corresponding to the VDI 2035 norm only (low-salt operation of the system).

3.4 FunctionLiquid refrigerant is evaporated (evaporator). The en-ergy for this process is ambient heat coming from the outside air. The gaseous refrigerant is compressed (compressor), which increases the pressure and thus also the temperature. The gaseous refrigerant with high temperature is liquefied (condenser). Here, the high temperature is transferred to the heat-ing water and used in the heating circuit. The liquid re-frigerant with high pressure and high temperature is expanded (expansion valve). The pressure and tem-perature drop and the process restarts.The heated heating water can be used for the domestic hot water or for heating the building. The temperatures required and the use are controlled by the heat pump controller. Any required reheating, support in screed drying or increase in the domestic hot water temper-ature can be carried out using an electric heating ele-ment, which is activated by the heat pump controller as required.

The integrated vibration decoupling for the hydraulic system prevents structure-borne sound and vibrations from being transferred to the fixed pipes and thus to the building.

CoolingCooling is integrated in the units. The following op-tions are possible for the cooling function ( operat-ing manual of the heating and heat pump controller):

● Active coolingCooling in combination with hydraulic module or hydraulic station up to a minimum flow temperature of 18 °C. In combination with wall-mounted control-ler up to a minimum flow temperature of 7 °C

● Cooling below 18 °C is only possible in the case of hydraulic integration with separation buffer tank

● The cooling function is controlled via the heating and heat pump controller

● Switching over between heating and cooling mode

4 Operation and care

Basic information relating to the electrical connection

● Any specifications by the local energy supply company apply to electrical connections

● Equip the power supply for the heat pump with an all-pole circuit breaker with at least 3 mm contact spacing (according to IEC 60947-2)

● Note the tripping current level ( “Technical data / scope of supply”, page 17)

● Comply with the electromagnetic compatibility regulations (EMC regulations)

● Install unshielded power supply cables and shielded cables (bus cables) sufficiently far apart (> 100 mm)

Connecting the heat pump module to the hydraulic module, the hydraulic station or the wall-mounted controllerThe connection is established using the EVS 8 or EVS accessory.

● EVS 8 load and bus connector with 8 m cable. (Can be extended inside buildings with a maxi-mum of 2 additional EVS 8)

EVS 8 installation instructions

● EVS: Load and bus connector. Cable on site, maximum cable length of 30 m. The bus cable must be a shielded cable of at least 4 x 0.5 mm². As load line:

● For the 12 kW unit a 5 x 2.5 mm² cable with protective conductor

● For the 8 kW unit a 3 x 2.5 mm² cable with pro-tective conductor

EVS installation instructions

1. Route the two plug-in connections of the load and bus cables to the slots on the heat pump module.

2. Join the connections.

3. Fit the cover for the plug connections.

8 Flushing, filling and venting

8.1 Heating water quality

NOTE ● For detailed information refer, among

other things, to the VDI Guidelines 2035 “Vermeidung von Schäden in Warmwasserheizanlagen” (preventing damage in hot water heating systems)

● Required pH value: 8.2 … 10; for aluminium materials:

pH value: 8.2 … 8.5 ► Fill the system with deionised heating water

(VE water) or with water corresponding to the VDI 2035 norm only (low-salt operation of the system).

Advantages of low-salt operation:

● Low corrosion-promoting properties ● No formation of mineral scale ● Ideal for closed heating circuits ● Ideal pH value due to self-alkalisation after filling

the system

► If the required water quality is not achieved, con-sult a company specialising in the treatment of heating water.

► Keep a system log for hot water heating systems in which relevant planning data is entered (VDI 2035).


Antifreeze in the heating circuitFor air/water heat pumps installed outdoors, it is not necessary to fill a water/antifreeze mixture into the heating circuit.The heat pumps have safety devices that prevent the water from freezing, even when the heating is switched off. A prerequisite is that the heat pump re-mains switched on and is not disconnected from the mains. Should there be a risk of frost, the circulation pumps are activated.

The following points must be observed if antifreeze is added, depending on the concentration of the mixture:

● Heat output of the heat pump is reduced ● COP value becomes worse ● In the case of on-site circulating pumps, the deliv-

ery rate is reduced; in the case of integrated cir-culating pumps, the specified free pressure drops

● The compatibility of the material of the compo-nents used with the antifreeze mixture must be ensured

8.2 Flushing, filling and venting the heating circuit

Outlet pipe of the safety valve is connected.

► Ensure that the response pressure of the safety valve is not exceeded.

NOTEThe venting program on the controller can also be used to support the flushing and vent-ing process. It is possible to control individual circulation pumps and even the changeover valve via the venting programs. As a result it is not necessary to remove the valve motor.

1. Vent the system at the highest point.

2. Vent the heat pump at the hydraulic connection set.

9 Insulation of hydraulic connections

Insulate hydraulic lines in accordance with the local regulations.

1. Open shut-off devices.

2. Perform a pressure test and check for leaks.

3. Insulate external piping on site.

4. Insulate all connections, fittings and pipes.

5. If the unit is used for cooling below 18 °C (only pos-sible in combination with the wall-mounted control-ler), the insulation must be vapour diffusion-tight.

6. Insulate the condensate drain in a frost-proof manner.

7. Fit the cover hood on the connection set.

8. The unit must be completely closed on all sides to ensure rodent protection.

10 Setting the overflow valve

NOTE ● The activities in this section are only nec-

essary for the integration of the storage tank in series.

● Complete the work steps quickly, other-wise the maximum return temperature could be exceeded and the heat pump will switch to high-pressure fault.

● Turn the rotary-push button on the over-flow valve to the right to increase the tem-perature difference (the spread), turn it to the left to reduce it

The system is running in heating mode (ideally in cold condition).

The IBN assistant already provides the option, in the event of the integration of the storage tank in series to adjust the overflow valve according to to the hydrau-lic system.

Confirm the IBN assistant or:


The “Set bypass valve” menu item is set by default to “No”. The overflow valve adjustment function is deac-tivated.

● The UWP control signal is the indication of the currently required pump capacity in %

● If the flow rate is the current flow rate (measuring accuracy +/- 200 l/h)

1. Fully open the overflow valve, close the heating circuits

2. If the “Set bypass valve” menu item is set from “No” to “Yes”, the circulation pump is activated with 100% – and the pump starts up.

3. If the control signal UWP reaches 100%, close the overflow valve to the extent that the maximum flow rate ( “Technical data / scope of supply”, page 17) can be ensured.

1 Rotary-push button2 Overflow valve

4. If you exit the “Set bypass valve” menu or at the latest after one hour, the circulation pump switch-es back to standard regulation

5. Open valves to heating circuit.

11 Commissioning

12 Maintenance

NOTEWe recommend that you conclude a mainte-nance agreement with your specialist heating company.

12.1 Basic principlesThe cooling circuit of the heat pump does not require any regular maintenance.

Local regulations – e.g. EU directive (EC) 517/2014 – specify tightness checks beforehand and/or for a log book to be kept for certain heat pumps.

► Ensure compliance with the local regulations re-lating to the specific heat pump system.

12.2 Maintenance as required ● Check and clean the components of the heating

circuit, e.g. valves, diaphragm expansion vessels, circulation pumps, filters, dirt traps

● Test the function of the safety valve for the heat-ing circuit

● Always regularly control for unimpeded air in-feed accordingly. Constrictions or even blockages which, for example occur

● when applying house insulation with polysty-rene balls

● through packaging material (foils, films, car-tons etc.)

● through foliage, snow, icing or similar weath-er-related deposits

● through vegetation (bushes, tall grass etc.) ● through air shaft covers (fly protection screens

etc.) and which must be prevented and/or removed im-mediately

● Check at regular intervals that the condensate can drain out of the unit freely, without obstruc-tion. To this end, check the condensate pan in the unit and the evaporator regularly for dirt/clogging and clean as necessary

Check the evaporator and the condensate pan and clean them, if required1. Remove the front panel, the side panels and the

cover, thus gaining access to the cover of the cleaning opening (①).

2. After the cover is removed (①), the entire conden-sate pan area before (②) and after (③) the evap-orator is visible and can be cleaned if necessary.

Heat source inlet sensor

As an alternative, the fan module can be removed to obtain additional access.

 “Optional separation of the fan module“, page 9


12.3 Cleaning and flushing the condenser

► Clean and flush the condenser according to the manufacturer’s instructions.

► After flushing the condenser with chemical clean-ing agent: neutralise any residues and flush the condenser thoroughly with water.

12.4 Annual maintenance ► Determine the quality of the heating water by

analysis. In the event of deviations from the speci-fications, take suitable measures without delay.

13 Malfunctions ► Read out the cause of the malfunction via the diag-

Aufstellungshinweise für Anschluss der Kondensatleitung außerhalb des Gebäudes.

KS Kiesschicht zur Aufnahme von bis zu 50l Kondenswasser pro Tag als Pufferzone zum Versickern.3 Kondensatablaufrohr DN 40

Wichtig: Bei direktem Einleiten des Kondenswassers in eine Abwasser- oder Regenwasserleitung muss ein Syphon gesetzt werden (Abbildung 1b). Es muss ein oberhalb des Bodenreichs senkrecht verlegtes Kunststoffrohr verwendet werden. Weiterhin dürfen im Abflussrohr keine Rückschlagklappen oder ähnliches installiert sein. Das Kondensatablaufrohr muss so angeschlossen werden, dass das Kondensat frei in die Hauptleitung einfließen kann. Wird das Kondensat in Drainagen oder in die Kanalisation abgeleitet, ist auf eine Verlegung mit einem Gefälle zu achten.

In allen Fällen (Abbildung 1a und Abbildung 1b) muss gewährleistet sein,dass das Kondenswasser frostfrei abgeführt wird.
