WARNING Injury
Keep the discharge aperture on the top of the ap-
pliance and the intake aperture on the side of the
appliance clear.
A fan is installed in the appliance, which generates a negative
pressure in the device. If the negative pressure can no longer be
built up (damaged sealing tape), the safety pressure cell shuts
down the appliance. A message appears in the heat pump man-
ager.

Replace the sealing tape if required.
In the event of a leak, the fan mixes the refrigerant gas into the
air in the room sufficiently.
Maintain the minimum installation area of the installation
room.

Increasing the minimum installation area
If the minimum installation area in the installation room is not
achieved, the installation room can be connected to a neighbour-
ing room via dilution apertures. The apertures must be located
near the ceiling and the floor. If the ceiling is suspended and there
is no wall to the next room, the upper aperture is not required.

8.2 Installation site
!
Material losses
Install the appliance only in rooms without a con-
stant ignition source (e.g. open flames, a live gas
appliance or an electric heater) or without open flue
boilers.
Note
The appliance is designed for indoor installation, except
in damp areas.
Never install the appliance directly below or next to bed-
rooms.
Route the pipe outlets through walls and ceilings with struc-
ture-borne noise insulation.
The room in which the appliance is to be installed must meet the
following conditions:
- Free from the risk of 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 minimum volume of the installation room must be ob-
served (see chapter "Preparation/ Safety concept").
- Load bearing floor (for the weight of the appliance, see chap-
ter "Specification/ Data table").
Ensure that the safety valve for the brine circuit is installed
in the installation room. Alternatively, outdoor installation is
also possible.
Ensure that the substrate is level, even, solid and permanent.
For installation on floating screeds, make provisions for quiet
heat pump operation.
Isolate the installation surface around the heat pump by
means of a recess. After completing the installation, seal the
recess with a waterproof, sound insulating material, suchas
silicone.
