Installation
5.1 General
The device should always be installed on a permanently smooth,
even and horizontal surface. The entire frame should lie directly
on the floor to ensure an adequate soundproof seal and to pre-
vent the water-bearing components from becoming too cold. If
this is not the case, additional insulation measures may be nec-
essary. Furthermore, the heat pump should be set up so that the
air outlet direction of the ventilator is perpendicular to the main
wind direction to allow unrestricted defrosting of the evaporator.
The heat pump is designed for installation on even ground. If the
installation conditions differ (installation on a platform or flat roof)
or there is a greater risk of the heat pump tipping over (due to an
exposed position or high wind exposure), additional protection
against tipping over must be provided. The responsibility for the
heat pump installation lies with the specialist system construction
company. During the installation, local requirements such as
building regulations, static load of the building, and wind expo-
sure must be accounted for.
It must be possible to carry out maintenance work without hin-
drance. This is ensured if the clearance displayed below is main-
tained..
The specified dimensions are valid for stand-alone installation
only.
ATTENTION!
Do not restrict or block the area around the air intake or outlet.
ATTENTION!
Observe country-specific building regulations!
ATTENTION!
For installation close to walls the physical influences of the building must
be considered. No windows or doors should be present in the area
surrounding the air outlet of the ventilator.
ATTENTION!
In cases of installation close to a wall, there may be more sediment in the
air inlet and outlet areas due to the air current. The colder outside air
outlet should discharge in such a way as to not increase the heat losses
in heated neighbouring rooms.
ATTENTION!
Installation in a hollow or in an inner courtyard is not permitted because
cooled air collects at ground level and is drawn in again by the heat pump
during lengthy operation.

5.2 Condensate pipe
Condensate that forms during operation must be drained off
frost-free. To ensure proper drainage, the heat pump must be
mounted horizontally. The condensate pipe must have a mini-
mum diameter of 50 mm and must be fed into a sewer in such a
way that it is safe from frost. Do not discharge the condensate di-
rectly into clearing tanks or cesspits, as aggressive vapours or a
condensed water pipe which has not been laid in a frost-free
manner could destroy the evaporator.
ATTENTION!
The frost line can vary according to the climatic region. The regulations
of the countries in question must be observed.

Assembly
6.1 General
The following connections need to be established on the heat
pump:
Flow and return of the heating system
Condensate outflow
Control line to the heat pump manager
Power supply
All panelling can be removed to allow accessing the inside of the
device.
Loosen the screws for this purpose. The lower panels can be re-
moved toward the top when slightly tilted.

The upper panels are hooked into the cover panel. Loosen the
two screws for dismantling and unhook the panels by pulling
them back.
