INSTALLATION
8. Safety
Only a qualified contractor should carry out installation, commis-
sioning, maintenance and repair of the appliance.
8.1 General safety instructions
We guarantee trouble-free function and operational reliability only
if original accessories and spare parts intended for the appliance
are used.
8.2 Instructions, standards and regulations
Note
Observe all applicable national and regional regulations
and instructions.
9. Appliance description
9.1 Mode of operation
The heat exchanger on the heat source side (evaporator) extracts
natural heat from the heat source. Any energy extracted is trans-
ferred, together with the energy drawn by the compressor drive,
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.
The electric emergency/booster heater starts if the high pressure
sensor or the hot gas limiter responds during DHW heating. In
addition it covers any residual heat demand, if the heating system
demand exceeds the heat pump output.
9.2 Special features of the WPF...cool
For cooling, the brine is pumped, via a further three-way valve
through a second heat exchanger, where the energy is extracted
from the heating water.

10. Preparations
Note
The appliance is designed for internal installation, except
in wet areas.
Never install the appliance directly below or next to
bedrooms.
Protect pipe transitions through walls and ceilings with an-
ti-vibration insulation.
The room in which the appliance is to be installed must meet the
following conditions:
- No risk from frost.
- The room must not be subject to a risk of explosions arising
from dust, gases or vapours.
- When installing the appliance in a boiler room together with
other heating equipment, ensure that the operation of other
heating equipment will not be impaired.
- The volume of the installation room should be at least
13.8m³.
- Load-bearing floor (for the weight of the internal unit, see
chapter “Specification / Data table”).
For installation on floating screeds, make provisions for quiet
heat pump operation.
Isolate the mounting surface around the heat pump by re-
cesses. After completing the installation, seal these recesses
with a water-impervious and sound insulating material, such
as silicone for example.
