Installation
7.1 General Information
The following connections need to be established on the heat
pump:
Flow and return flow of the brine system
Flow and return flow of the heating system
Power supply
7.2 Heating System Connection
ATTENTION!
Flush the heating system prior to 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.
Once the heating system has been installed, it must be filled, de-
aerated and pressure-tested.
Minimum heating water flow rate
The minimum heating water flow rate through the heat pump
must be assured in all operating states of the heating system.
This can be accomplished, for example, by installing either a
manifold without differential pressure or an overflow valve. The
procedure for adjusting an overflow valve is described in the
Chapter Start-up.
Antifreeze protection for installation locations
prone to frost
The antifreeze function of the heat pump controller is active
whenever the controller and the heat circulating pumps are ready
for operation. If the heat pump is taken out of service or in the
event of a power failure, the system has to be drained. The heat-
ing circuit should be operated with a suitable antifreeze if heat
pump systems are implemented in buildings where a power fail-
ure can not be detected (holiday home).
7.3 Heat Source Connection
The following procedure must be observed when connecting the
heat source:
Connect the brine pipe to the heat pump flow and return. The hy-
draulic plumbing diagram must be adhered to.
ATTENTION!
The supplied dirt trap must be inserted in the heat source inlet of the heat
pump to protect the evaporator against the ingress of impurities.
In addition, a micro bubble air separator must be installed in the
heat source system.
The brine liquid must be produced prior to charging the system.
The liquid must have an antifreeze concentration of at least
25% to ensure frost protection down to -14 °C.
Only monoethylene glycol or propylene glycol-based antifreeze
may be used.
The heat source system must be de-aerated and checked for
leaks.

ATTENTION!
The brine solution must contain at least a 25% concentration of a
monoethylene glycol or propylene glycol-based antifreeze, which must
be mixed before filling.

All components required for the power supply of the heat pump
are located in the basic control. The basic control is installed in-
side the house on a wall with a level surface. A heat pump con-
troller is required for controlling these components. The individ-
ual components such as the basic control and the heat pump
controller must be connected on-site (plug connector).
Power feed for basic control
An all-pole disconnecting device with a contact gap of at least
3 mm (e.g. utility blocking contactor or power contactor) as well
as a 3-pole circuit breaker with common tripping for all external
conductors must be installed in the power supply for the basic
control. The required conductor cross section is to be selected
according to the power consumption of the heat pump, the tech-
nical connection requirements of the relevant electrical utility
company and VDE 0100 regulations. The power consumption of
the heat pump is specified in the technical documentation. The
connection terminals (X1-L1/L2/L3 at the circuit breakers) are
2
designed for a max. of 16 mm
