► Dispose of the media in an environmentally compati-ble way in accordance with the local regulations.

2.6 Avoid damage to propertyThe ambient air at the heat pump installation site, as well as the air drawn in as a heat source, must not contain any corrosive constituents!

Constituents such as

● Ammonia ● Sulphur ● Chlorine ● Salt ● Sewergasses,fluegasses

can cause damage to the heat pump, which could lead to the complete failure / destruction of the heat pump!

Decommissioning/emptying heatingIf the system / heat pump is decommissioned or emptied,afterithasbeenfilledalready,itisnecessaryto ensure that the condenser and any heat exchangers present have been completely emptied in the event of frost. Residual water in heat exchangers and condensers can result in damage to components.

► Empty system and condenser completely, open vent valves.

► Blast out with compressed air if necessary.

Improper actionRequirements for minimum scale and corrosion damage in hot water heating systems:

● Proper planning, design and commissioning

● Closed system with regard to corrosion

● Integration of an adequately dimensioned pressure maintaining device

● 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, designed, started up and operated in accordance with the given requirements, there is a risk that the following damage and faults will occur:

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

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

● Cross-section reduction and blockages in components, e.g. heat exchanger, pipes, pumps

● Material fatigue

● Gas bubbles and gas cushion formation (cavitation)

● Negativeeffectonheattransfer,e.g.formationofcoatings, deposits, and associated noises, e.g. boilingnoises,flownoises

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

Unsuitablequalityofthefillandmake-upwater in the heating circuitThe efficiency of the systemand the life of the heatgenerator and the heating components depend decisively on the quality of the heating water.

If the system is filled with untreated drinking water,calcium precipitates as scale. Limescale deposits form on the heat transfer surfaces of the heating. The efficiency drops and energy costs rise. In extremecases the heat exchangers are 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).

The nameplate also contains an overview of the most important technical data.


3.4 FunctionLiquid refrigerant is evaporated (evaporator), the ener-gy for this process is environmental heat and comes from the outside air. The gaseous refrigerant is com-pressed (compressor), this causes the pressure to rise and therefore the temperature too. The gaseous refrig-erantwithhightemperatureisliquefied(condenser).

Here the high temperature is discharged to the heating water and is used in the heating circuit. The liquid refrigerant with high pressure and high temperature is expanded (expansion valve). The pressure and temperature drop and the process begins again.

Due to the integrated switching valve and the integrated energyefficiencycirculationpumptheheatedheatingwater can be used for charging the domestic hot water or for heating the building. The temperatures required and use are controlled by the heat pump controller. Reheating, drying out screed or increasing the domestic hot water temperature can be carried out using the integrated electric heating element, which is activated by the heat pump controller as and when necessary.

An integrated overflow valve ensures that the heatpump does not switch to high-pressure fault if all heating circuits are closed. The integrated vibration decouplers for the hydraulics prevent structure-borne sound and vibrations from being transferred into the fixedpipesandthereforeintothebuilding.

CoolingCooling is integrated in the units. The following options are possible for the cooling function ( operating manual of the heating and heat pump controller):

● Active cooling

● Control of the cooling function via the heating and heat pump controller

(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 ● IdealpHvalueduetoself-alkalisationafterfilling

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).

9.2 Flushandfilltheheatinganddomestic hot water charging circuit

Outlet pipe of the safety valve is connected.

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

NOTEThe venting program on the controller can also be used to support the flushing andventing process. It is possible to control individual circulation pumps and even the switching valve through the venting program. As a result it is not necessary to remove the valve motor.

1. Pull the U-clip(2) off the floor of the valvemotor (1).


2. Pull the valve motor (1) carefully off the 3-wayswitching valve (3).

3. Turn the spindle of the 3-way switching valve so that the rounded side of the spindle points in the direction of marking A of the connections of the 3-way switching valve.

B

4. Flush the domestic hot water charging circuit for approx. 1 minute.

5. Turn the spindle so that the rounded side of the spindle points in the direction of marking B of the connections of the 3-way switching valve.

6. Flush heating circuit thoroughly, until no more air is discharged.

7. Vent system at the respective highest point.

8. Vent heat pump.

9. Position the valve motor (1) on the 3-way switching valve (3).

10. Insert the U-clip(2) into the floor of the valvemotor.

11. Ensure that the U-clip has latched into position correctly:

Valve motor sits securely on the 3-way switch-ing valve

Both prongs of the U-clip sit on the lug

The tips of the U-clip are visible by approx. 2mm(notsignificantlymore!)

10 Insulate hydraulic connectionsInsulate hydraulic lines in accordance with local regulations.

1. Openshut-offdevices.

2. Perform a pressure test and check for leaks.

3. Insulate external piping on site.

4. Insulateallconnections,fittingsandpipes.

11 Settheoverflowvalve

NOTE ● The activities in this section are only

necessary for integration of storage tank in series

● Complete the worksteps quickly, otherwise the maximum return temperature can be exceeded and the heat pump switches to high-pressure fault

● Turn the adjusting knob at the overflowvalve to the right to increase the temperature difference (the spreading),turn it to the left to reduce it

System is running in heating mode (ideally in cold condition).

There is a facility directly in the IBN assistant to adjust the overflow valve to suit the hydraulic system if thestorage tank is integrated in series.

ConfirmtheIBNassistantor:


The “Set bypass valve” menu item is set by default to “No”.Theoverflowvalveadjustmentfunctionisdeac-tivated.

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

● Iftheflowrateisthecurrentflowrate(measuringaccuracy +/- 200 l/h)

1. Fully open theoverflowvalve, close theheatingcircuit.

2. Set the menu point “Set bypass valve” from “No” to “Yes” and so the circulation pump is controlled with 100% – the pump starts up.

3. If the UWP control signal reaches 100%, close overflow valve far enough that the max. flowrate ( “Technical data / Scope of supply”, page 23) can be assured.

1 Overflowvalve2 Adjusting knob

4. If you leave the “Set bypass valve” menu or after one hour at the latest, the circulation pump switches back to its standard regulation.

5. Open valves to heating circuit.

12 Commissioning

CAUTIONThe unit may only be started up if the air ducts, weather and/or rain louvres have been installed and the facing panels are closed.

Relevant planning & design data of the system is documented in full.

Thecompetentenergysupplierhasbeennotifiedof operation of the heat pump system.

● The level of the tripping current is compliant

● Heatingcircuitisflushedandvented

● Allshut-offdevicesoftheheatingcircuitareopen

● The pipe systems and components of the system are leak-tight

2. Fill out carefully and sign the notice of completion for heat pump systems.

3. In Germany: Send notice of completion for heat pump systems and rough checklist to the manufacturer’s factory customer service department. In other countries: Send notice of completion for heat pump systems and rough checklist to the manufacturer’s local partner.


4. Arrange for the heat pump system to be commissioned by after-sales service authorised by the manufacturer; this is a chargeable service.

13 Maintenance

NOTEWe recommend that you sign a maintenance agreement with an accredited heating company.

13.1 Basic principlesThe cooling circuit of the heat pump requires no regular maintenance.

Local regulations– e.g. EU Regulation (EC) 517/2014 – among other things, require leakage controls beforehand and/or for a log book to be kept for certain heat pumps.

► Ensure compliance with local regulations with regardtothespecificheatpumpsystem.

13.2 Maintenance as required ● Checking and cleaning the components of the

heating circuit, e.g. valves, expansion vessels, circulationpumps,filters,dirttraps

● Test the function of the safety valve for the heating 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.) ● throughairshaftcovers(flyprotectionscreens

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

● Check regularly to ensure that the condensate can drain out of the unit freely, without obstruction. To this end, check the condensate pan in the unit and the evaporator regularly for dirt / blockages 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 evapo-rator is visible and can be cleaned if necessary.

Heat source inlet sensor

As an alternative, the lateral air ducts, the side walls, the louvre grilles and blind covers can be removed (if necessery also the fan module) , to obtain better ac-cess.
