6 INSTALLATION
5.1 General
The unit should always be installed on a permanently
level, smooth and horizontal floor. The entire base
frame surface should thereby make close contact with
the floor in order to ensure adequate sound insulation
and to prevent water-carrying parts from cooling out.
If this is not the case, additional insulation measures
may become necessary. It must be possible to carry
out servicing work without any problems. This is
ensured if a clearance of 1.2 m to solid walls is
maintained.
The intake and discharge openings
must not be restricted nor obstructed.
5.2 Condensate Line
The condensation water that may collect during
operation must be drained in a place protected from
frost. The heat pump must be positioned horizontally
so that proper discharge can be ensured. The
condensation water pipe must have a minimum
diameter of 50 mm and should be discharged to the
sewer drain in a frost-proof location.
MOUNTING
6.1 General
The following connections need to be established
on the heat pump:
- supply/return flow of heating system
- supply/return flow of hot water circuit
- condensate drain
- control lead to the heat pump controller
- power supply
6.2 Heating and Hot Water Connection
The connections on the heating side of the heat
pump are provided with 1"external thread. The hoses
to be connected exit the unit through its bottom. When
carrying out the connections, use a wrench to
counterhold at the transitions.
Before completing the heat pump connections on
the heating water side, the heating installation must
be flushed in order to remove any impurities that
may be present and to ensure trouble-free operation
of the heat pump. On systems equipped with heating
water flow shut-off devices such as radiator or
thermostat valves, an overflow valve to be provided
by the customer needs to be installed behind the
heating pump in a heating system bypass. This
guarantees a minimum heating water flow through
the heat pump and prevents any malfunctions from
occurring.
Once the installation on the heating side has been
completed, the heating system must be filled, de-
aerated and pressure-tested.
Frost Protection
As a precaution against frost, manual drain valves
should be provided. If the heat pump is placed out of
service or in the event of a power failure, the system
has to be drained at three points (see figure) and
blown out. In heat pump installations where a power
failure cannot be readily detected (holiday house),
the heating circuit must contain a suitable antifreeze
product.
