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.
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 can be ensured by maintaining a clearance of 1.2 m
to any fixed walls.
1) Minimum clearances for heat pump function
2) Minimum clearances for maintenance work
ATTENTION!
Do not restrict or block the area around the air intake or outlet.

5.2 Condensed 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 flow of the heating system
 Condensate outflow
 Control line to the heat pump manager
 Voltage supply

6.2 Connection on heating side

The heating system connections on the heat pump have a 1" ex-
ternal thread. Route the connection hoses out of the device in a
downwards direction. Use a spanner to firmly grip the transitions
when connecting the heat pump.
Before connecting the heating water system to the heat pump,
the heating system must be flushed to remove any impurities,
residue from sealants, etc. Any accumulation of deposits in the
liquifier could cause the heat pump to completely break down.
For systems in which the heating water flow can be shut off via
the radiator or thermostat valves, an overflow valve must be in-
stalled in a heating bypass behind the heat pump by the cus-
tomer. This ensures a minimum heating water flow rate through
the heat pump and helps to avoid faults.
Once the heating system has been installed, it must be filled, de-
aerated and pressure-tested.
Consideration must be given to the following when filling the sys-
tem:
 Untreated filling water and make-up water must be of drink-
ing water quality
(colourless, clear, free from sediments)
Filling water and make-up water must be pre-filtered (pore

size max. 5 µm).
Scale formation in hot water heating systems cannot be com-
pletely avoided, but in systems with flow temperatures below
60 °C the problem can be disregarded.
With medium and high-temperature heat pumps, temperatures
above 60 °C can be reached.
The following standard values should therefore be adhered to
concerning the filling water and make-up water (according to VDI
