INSTALLATION
7. Safety
Only a qualified contractor should carry out installation, commis-
sioning, maintenance and repair of the appliance.
7.1 General safety instructions
We guarantee trouble-free function and operational reliability only
if original accessories and spare parts intended for the appliance
are used.
7.2 Instructions, standards and regulations
Note
Observe all applicable national and regional regulations
and instructions.
The tested appliance conforms to IEC 61000-3-12.
8. Appliance description
The heat exchanger on the heat source side (evaporator) extracts
natural heat from the heat source. This extracted energy and the
energy drawn by the compressor drive is transferred to the heating
water by a heat exchanger on the heating water side (condenser).
Subject to the heat load, the heating water is heated up to +65 °C.
If the heat demand of the heating system exceeds the heating
output of the heat pump, the booster heater covers the residual
heat demand.
If the hot gas function is used, the heat pump can be used to
achieve DHW temperatures over 60 °C when heating without a
booster heater. The compressed refrigerant transfers the energy
absorbed by the compressor to the DHW in a hot gas heat ex-
changer. The refrigerant then flows into a second heat exchanger
in which the energy is transferred to the heating water.
Outside the heating season, DHW heating can be supported by a
booster heater.
The heat pump is not suitable for dry heating the screed.

9. Preparation
Note
The appliance is designed for indoor installation, except
in damp areas.
9.1 Sound emissions
Note
For details regarding the sound power level, see the
chapter “Specification / Data table”.
- Never site the appliance on joist floors.
f
f
Ensure that the entire appliance frame is in full contact with
the substrate. Uneven substrates can increase sound emis-
sions.
f
f
Never install the appliance directly below or next to a living
room or bedroom.
f
f
Avoid installation on large, echoing floor areas, e.g. tiled
floors.
f
f
Avoid installation between reflective building walls. Reflect-
ing building walls can increase the noise level.
f
f
Never install the appliance in the corner of the installation
room.
f
f
Implement pipe outlets through walls and ceilings with an-
ti-vibration insulation.
f
f
Use flexible supply lines.
f
f
Secure the supply lines with structure-borne noise attenua-
tion on noise-sensitive walls.
f
f
Ensure that the appliance feet are aligned.
