1.8 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).
1.9 CONFIGURATION
Congurations which are not allowed Consequences
Connection to the attic or loft space. When the insulation between the house and the attic is not
sufcient, through this connection the loss of heat may
increase. There is also the possibility that a growing of
moisture will happen at the ceiling of the rooms which are
directly below the attic. There is a chance that objects will
fall or dust will be drawn in by the VHW. This may reduce
the lifetime for the VHW.
The supply of air from a heated room by the VHW. The air which is drawn by the VHW is already warmed
by another heating source in the system. In this situation
the greatest benet of the VHW (the transmitting of ‘free’
energy into heat) is not used.
Connection to the mechanical ventilation. The volume of air required by the VHW isn’t suitable (380
/ 490 m/h) for the volume of air in a mechanical ventilation
(which is 100 m/u). Furthermore the vapor of grease and
dust in the ducts of the mechanical ventilation can circulate
through and that may cause a shorter lifetime for the VHW.
Making of a housing around the air outside or a repulsion of
fresh air inside. This will cause a big loss in the coefcient of performance
and a strong cooling in the room.
Connection to a ground heat exchanger. - Friction losses.
- Problems with the symmetrisation of the two fans inside
the ground heat exchanger.
- The evaporator will likely become clogged.
Also not allowed:
• Make a ventilation connection with a dryer.
• Install in dusty room.
• Take air in which contains solvents and / or explosive substances.
• Connect the VHW to an extractor fan wich drains oily and contaminated air.
• Install the VHW in a room where there is a change of frost.
• Install the VHW on top of the boiler.
• Install in an atmosphere which is chlorinated (e.g. a swimming pool) or uorinated.
• Install nearby sea areas or chemical plant
• Dusty air intake.

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).
The VHW must be installed in an easy accessible room in order
to make maintenance and removal at the end of the lifetime
possible.
If the appliance only has one duct (inlet & outlet duct), its operation
may create negative or positive pressure in the installation room.
If other appliances 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.

Connect the condensate hose to the collection area. (2)
Drain off condensate via a siphon drain. (3)
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 (L) 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
10 m hose 19,0 m
45° elbow 0,9 m
90° elbow 2,0 m
90° exible 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 noise level.

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
Calccium 20 p.p.p. (if pH between 7,3 and 8,3)
Iron 0,2 p.p.m.
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.

“P2” and “P3” operating modes: selecting this menu causes the appliance to run according to the user-set operating
times.
4.6.3 “FULL” OPERATING MODE
In this operating mode, the two internal heat appliances are used at the same
time: the heat pump and the electric booster heater.
The appliance performance decreases in “Full” operating mode. For this
reason, it must only be used when the water temperature needs to be
increased rapidly.
The water temperature can be set to between 30 °C and 70 °C.
Both heat appliances are used at the same time until the desired temperature
is reached. Only the electric booster heater is used at temperatures above
60 °C. The display shows “Full” until the desired temperature is reached.
As soon as the set DHW temperature is reached, the appliance switches from
the “Full” operating mode back to the previously set operating mode. “Quick”
