1.7 OPERATING PRINCIPLE OF THE VENTILATION HEAT PUMP WATER HEATER
The Ventilation Heat Pump Water heater consists
ofanexpansionvalve(1),anairheatexchanger(2),
a compressor (3) and a water heat exchanger (4).
A refrigerant circulates in the closed system (5). In
theexpansionvalve,thepressureandtemperature
oftherefrigerantarelowered,whichbecomes
vaporous. It extracts heat from the air (6) via the air
heat exchanger. The vapour is then compressed
by the compressor. This increases the pressure
and the temperature (7). The heat is transferred to
the water via the water heat exchanger (8). And the
cycle begins anew. It is therefore possible to heat
water with a low temperature of 10 ºC to domestic
hot water with a temperature of 60 ºC. This makes
it possible to create four parts of energy (heat) from
just one part of energy (electricity).

Safety of electrical appliances for domestic use and similar purposes
ThefollowingrequirementsapplyinaccordancewithEN60335-1inordertopreventhazardsfromoccurring
whenusingelectricalappliances:“Thisappliancemaybeoperatedbychildrenaged8oroverandbypeoplewith
fullphysical,sensoryandmentalcapabilitieswhohavethenecessarytrainingandexperiencetousethistypeof
appliance. They must be supervised or instructed on how to use the appliance safely and on the associated risks.
Children must not play with the appliance. Children must not clean or service the appliance without supervision.”
“Damagedpowercablesmustbereplacedbythemanufacturer,theservicedepartmentoraqualiedcontractorin
ordertopreventhazards.”
2.1 SAFETY, CONTROL AND PROTECTION DEVICES
2.1.1 HIGH PRESSURE SWITCH
Iftheoperatingpressureisoutsideoftherecommendedrange,thepressureswitchswitchesofftheapplianceand
displays a fault.
2.1.2 HIGH LIMIT SAFETY CUT-OUT
The high limit safety cut-out ensures that the water temperature in the cylinder does not exceed the prescribed limit.
Ifthetemperaturelimitisexceeded,theDHWheatingshutsdown.Theresetisperformedmanuallybyacertied
contractor.
2.1.3 TEMPERATURE SENSOR FOR AIR INLET
The temperature sensor measures the temperature of the inlet air in the evaporator. If the measured value is outside
theoperatingtemperaturerange,DHWheatingautomaticallyswitchesfromthe“Combi”operatingmodeto“Electric
boosterheater”.Iftheapplianceisinthe“Heatpump”operatingmode,DHWheatingisinterrupteduntilthe
temperature returns to within the permissible range.

3. INSTALLATION
•Theappliancemayonlybeinstalledbyanauthorizedcontractor.
•The heat pump installation must follow the applicable regulations.
•Check that all pipe connections are intact and have not shaken loose during transportation.
NOTICE:Refrigerantleak!
•Onlyauthorizedcontractorsarepermittedtomaintainandrepairtherefrigerantcircuit.
3.1 INSTALLATION LOCATION
Pleasenotethefollowingwhenchoosingtheinstallationlocation:
•Theappliancemustbeinstalledinadry,frost-freeroom.The
supply air temperature must be between -10 °C and 35 °C in
ordertooptimizetheapplianceperformance.
•Theappliancemustbeinstalledonasufcientlystrongandlevel
surface.
•The air outlet and air inlet must not be in locations where there is
ariskofexplosioncausebygas,steamordust.
•Ensure that condensate drains correctly.
•The surface below the appliance must be strong enough (the
applianceweighsabout400kgwhenthecylinderislled,with
the weight distributed equally over its 3 adjustable feet).
Iftheapplianceonlyhasoneduct(inletoroutletduct),itsoperation
may create negative or positive pressure in the installation room. If
otherburnersarealreadyinstalledinthesameplace,pleasebearin
mind that the appliance requires a clearance of at least 220 cm2 for
the air inlet and outlet in order to operate correctly.
Note:Theclearanceof220cm2isrequiredforthecorrect
functioning of the heat pump only.
To ensure faultless operation and easy access to all components
andconnectionsforserviceandmaintenance,maintainthe
minimumclearancesspeciedingure1.
Installing the appliance
•Remove external protective packaging.
•Lifttheappliancefromitspalletandpositionitonitsnalplinth.
Watch out for damaging the metal hood of the HP-unit. Only lift at
thevesselpart!
•Tocorrectlyaligntheapplianceattheinstallationlocation,adjust
the height of the adjustable feet.
•Assurecorrectpositioningofalltemperaturesensors,seegure
2 and 3.
To ensure that the system operates faultlessly and the condensate
drainscorrectly,theappliancemustbealignedvertically.The
appliancemusttilt1°,intothedirectionofthecondensatedrain.
NOTICE:Possibledamagetoexternalcasing!
•Do not tilt the appliance on his feet more than 20°.

3.2 CONNECTING THE CONDENSATE HOSE
Damagetotheappliance!Connectthecondensatehosetothe
condensate drain before installing the part.
•Donotbendthecondensatehose!
Thecondensateisdrainedontherearsideoftheappliance,
seegure4.
•Connect the condensate hose to the condensate drain (1)
•Connect the condensate hose to the collection area.
•Drain off condensate via a siphon drain (2)
Don’tdisconnectthecondensatehosefromthecondensatedrain,
thiswilldamagetheconnectioninthefoam!
3.3 CONNECTING THE DUCTS
Theairinletcanbelocatedintheinstallationroom,inadifferentroomoroutside.Inthelattertwocases,airinlet
ducts must be installed. If ducts are used select “ducts on”. (see 4.8.5)
Toensuremaximumapplianceperformanceandtopreventcondensationformingontheexternalductwalls,use
thermally and acoustically insulated ducts.
Whenchoosingaroomfortheairinlet,observetheaverageairtemperatureandrequiredairowrate.Inorderto
minimizeairresistance,laytheairinletandoutletducts(Ø160mm)asstraightaspossible.
Thelength(Leq)oftheairinletandoutletductsmustnotexceedthefollowingvalues:
•30m at fan speed 1 (SP1)
•30m – 60m at fan speed 2 (SP2)
Air inlet Air outlet
0,5mduct 0,5m
1 m duct 1,0m
2m duct 2,0m

45° elbow 0,9m
90° elbow 2,0m
90° flexible curve 2,3m
Weather grille 8 m 4 m
Roof output 7 m 4 m
To ensure that condensate forming in the air inlet and air outlet
ductsdrainsfromtheappliance:
•Install air ducts at a slight angle to the air inlet and air outlet
apertures on the top side of the appliance.
Always use insulated pipes to prevent condensate at the air inlet
and the air outlet. By the use of outside air condensate can occur.
It’s recommended to use SP2 if ducts are used with a high
resistance. (To select SP2 see 4.8.4)
Please note that a high ventilator volume results in a higher sound
level.

3.4 FILLING THE CYLINDER
Damagetotheappliance!Priortocommissioningtheappliance,ll
thecylinderwithwaterandbleedthesystemifnecessary.
Filling the cylinder
•Open the water outlet valve and at least one hot water tap.
•Openthewaterinletvalveonthecylinder.Thecylinderislled.
•Donotclosethehotwatertapsuntilthewaterowssteadilyand
is free from air bubbles.
•Connect the appliance to the power supply via a separate socket
with an earth connection.
•Call up the “Purg” function. (see 4.8.6)
•Set the selector switch on the DHW pump to “III”. (Fig.5(1))
CAUTION:Riskofscalding!Ensurethatdrainingwaterfromtheair
vent screw presents no risk to people or property.
Openthedrainscrewontheheatingpump(Fig.5(2))untilthewaterowssteadilyandwithoutairbubbles.
•Close the drain screw on the heating pump.
•Waitaround5minutesuntilthe“Purg”operatingmodehasnished.
•Settheselectorswitchontheheatingpumpto“I”.Theprocessofdrainingandllingthecylinderiscomplete.
Ifthefaultcode“E09”appearsonthedisplayafterafewminutes,proceedasfollows:
•Clear the fault
•Rellmanually.
3.4.1 WATER QUALITY
Waterqualityvaries,inordertoensurealongandtroublefreelifetheheatpumpthefollowingvaluesshouldnotbe
exceeded.
Total hardness 200 p.p.m.
Chloride 250 p.p.m.
Sulphate 250 p.p.m.
Magnesium 10 p.p.m.
Sodium 150 p.p.m.
pH Min 6.5 and Max 8.5
Inadequate water quality or contaminated water can damage the appliance. Scaling is more important at higher
watertemperature.Incaseofwaterhardnessabove600mg/l,theLangeliersaturationindexmustbedeterminedto
evaluate the necessity for water treatment.
Check the guideline 98/83/EG for the minimal requirements about potable water.
Note:Inregionswithmorecorrosivewater,safetymeasures(lter,etc.)mustbetaken.Therstinspectionmust
always take place 6 months after installation.
