DEVICE DESCRIPTION
This device is a domestic hot water (DHW) heat pump.
It works as a DHW generator that operates automatically and has a capacity of approx. 300 l. The water
temperature is permanently set to 60 ¡C.
Function Description
The device extracts heat from the ambient air.
This energy is used to heat the water inside the cylinder. Where the device is installed inside a room, this is cooled
down through the heat extraction by approx. 1 to 3 ¡C. The device also extracts moisture from the ambient air that
creates condensate, which must be drained off. For this purpose, a condensate drain is integrated into the unit.
Heat Pump Operation
The table below outlines the standard operating mode, to which the limits of scope of the heat pump apply. To
heat up the cylinder capacity of approx. 300 litres of water in accordance with EN 255 part 3 to 60 ¡C, the device
requires:
HEAT-UP TIME [H] ROOM TEMPERATURE [¡C] RELATIVE HUMIDITY [%] COLD WATER TEMPERATURE [¡C] COP
10 15 70 15 3.19
542 70 15 5.61
!

5
Note
If the heat pump is switched OFF and ON again, for instance after a power failure, the compressor will only
re-start (after approx. 3 minutes), when the pressure inside the refrigerant circuit has normalised again.
Operation With Active Defrost Feature
Note
The heat pump must not be installed in areas where ambient temperatures frequently exceed 42 ¡C or
areas where temperatures frequently drop below 0 ¡C.
Subject to the relative humidity and the DHW temperature, the evaporator begins to build up hoar frost at an
ambient temperature below 6 ¡C.
If the evaporator is covered in hoar frost, the frost monitor N2 (see wiring diagram) switches the fan OFF, whilst the
compressor continues to run, and the changeover valve V2 routes the hot gas directly to the evaporator. For this,
the condenser is shut off by changeover valve V1. When the temperature at the evaporator fins rises above 3 ¡C,
the fan is started again, and DHW heating continues.
The DHW heat pump can be operated at ambient temperatures as low as 0 ¡C. The evaporator is defrosted
according to demand in the temperature range 0 ¡C to +6 ¡C. This extends the heat-up time.
MAINTENANCE AND CLEANING
Material Losses
The sacrificial anode must be checked by a licensed tradesperson 12 months after the unit has been in-
stalled and checked periodically thereafter as advised by the licensed tradesperson.
Failure to do so may void your warranty.
Note
Maintenance work, e.g. checking the electrical safety, must only be carried out by a licensed tradesperson.
The device is generally maintenance free, with the exception of cleaning the condensate drain and having a
licensed tradesperson check the sacrificial anode.
A damp cloth is sufficient for cleaning all parts. Never use scouring or solvent-based cleaning agents.
- Check at least monthly the condensate drain at the middle of the unit and the condensate pan drain at the top
(visual check). Remove contaminants and blockages immediately.
- Ask your local tradesperson to regularly check the safety assembly and the electric booster heater.
- The device is subject to mains water pressure. The expansion water drips from the safety valve during heat-up.
Inform your local tradesperson of water drips from the system after the heat-up process has ended.
- To protect the steel cylinder against corrosion, the interior is coated with a special enamel and is furthermore
equipped with a protective anode. Ask your local tradesperson to check the protective anode 12 months after
installation and periodically thereafter as advised by your local tradesperson. A sacrificial anode maintenance log
is located on page 9 of this manual for your local tradesperson to fill in. Your local tradesperson, who is familiar
with the local water quality, should identify for you the timing of the next service.

TROUBLESHOOTING
No Hot Water
Should you fail to obtain hot water at any time, you can take the following steps to remedy that situation:
No Electrical Power
Check the fuse/circuit breaker in your fuse box. If it has blown/tripped, replace/reset the fuse/MCB. If it should
blow/trigger repeatedly, notify your local tradesperson.
Still No Hot Water, Even Though Power Is Available
Check, whether the air inlet/outlet is blocked.
The thermoswitch trips out or the high limit safety pressure limiter switches the compressor OFF if the compressor
is overloaded due to excessive ambient temperature or excessive air temperature (>42 ¡C), or because of a fault in
the refrigerant circuit. If this happens repeatedly, ask your local tradesperson to remove the fault.
After a short cooldown phase, the thermoswitch will restart the compressor automatically.
Material Losses
The high limit safety pressure limiter must only be reset by your licensed tradesperson after they have re-
moved the cause of the relevant fault.
Other Issues
Safety Valve Of The Cold Water Supply Line Drips
This may occur during the heat-up phase and is completely normal.
The Condensate Drain Drips
This always happens when the surface temperature of the evaporator is lower than the ambient dew point
temperature.
Notifying A Licensed Tradesperson
If you cannot remedy the fault, notify your licensed tradesperson. To facilitate and speed up your request, provide
the serial number from the type plate (000000-0000-000000).

CLEANING THE EVAPORATOR
!
Warning Injury
The evaporator has many sharp-edged fins. When cleaning the evaporator, proceed with caution and wear
protective clothing, in particular safety gloves.
Maintaining the full output of the water heater at all times requires an occasional professional cleaning of the
evaporator.
Undo the screws that connect the water heater cover and remove.
Carefully clean the evaporator fins. Only use water and a soft brush. Never use acidic or alkaline cleaning agents.
ON THE EQUIPMENT
Warning Electrocution
Before any work on the equipment, disconnect all poles from the mains.
In case of a fault, the safety equipment of the device interrupts the relevant power circuit.

Draining The Cylinder
!
Warning Injury
Hot water can be expelled during draining.
Close the shut-off valve in the cold water supply.
Fully open the hot taps at all draw-off points.
The cylinder is drained via the cold water inlet line. Open the drain valve. If no drain valve was installed, undo the
fitting on the cold water supply of the appliance. Residual water remains in the lower part of the cylinder.
ON THE SYSTEM
Material Losses
If the hot water unit is not used for two or more weeks, an amount of highly flammable hydrogen gas may
accumulate in the water tank. To dissipate this gas safely, it is recommended that a hot tap be turned on
for several minutes or until discharge of gas ceases. Use a sink, basin or bath outlet, but not a dishwasher,
clothes washer or other appliance. During this procedure, there must be no smoking, open flame or any
electrical appliance operating nearby. If hydrogen is discharged through the tap, it will probably make an
unusual sound as with air escaping.
Safety Valve
This valve opens when the water pressure exceeds the preset value of 0.7 MPa thereby relieving the pressure. It
is adjusted so that no water will be expelled when heating is switched OFF. Should it continue to drip excessively,
either the valve seat has become contaminated, the water pressure is too high or the pressure reducing valve has
become faulty.
Regular Valve Maintenance
Safety requires that valves are regularly checked for perfect function.
Regularly vent the safety valve until a full stream of water flows from it. Close the safety valve after checking.
How quickly limescale builds up depends on the local water quality.
As your local tradesperson is familiar with your local water quality, let them determine the timing of this check.
