MOUNTING
7.1 General
The following connections need to be established on
the heat pump:
- supply/return flow of the brine system
- supply/return flow of the space heating and
water heating system
- common return of space heating and water
heating system
- return, overflow valve
- connection for additional expansion vessel
(as required)
- drain lines of overflow valves
- condensate drain
- power supply
7.2 Heating-Side Connection
The heat pump features separate outlets for the space
heating and water heating circuit.
In cases where the heat pump has no water heating
mode, the hot water outlet has to be permanently
sealed.
Prior to establishing 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 , as well as residues of sealing
material, or the like. Any accumulation of deposits in
the condenser may result in a total failure of the heat
pump.
In systems equipped with heating water flow shut-
off devices such as radiator or thermostat valves, an
overflow valve is installed. This assures a minimum
heating water flow through the heat pump and
prevents any malfunctions for occurring.
Once the installation on the heating side has been
completed, the heating system must be filled,
deaerated and pressure-tested.
Frost Protection for Installations Prone to Frost
Provided the controller and the heating circulating
pumps are ready for operation, the frost protection
function of the controller is always activated. If the
heat pump is taken out of service or in the event of a
power failure, the system must be drained. In heat
INSTALLATION
6.1 General Information
As a rule, the unit must be installed indoors on a
level, smooth and horizontal surface. The entire base
frame should thereby make close contact with the
surface in order to ensure adequate sound
insulation. Failing this, additional sound insulation
measures may become necessary.
The heat pump should be located to allow safe and
easy maintenance/service access. This is ensured
if a clearance of approx. 1 m in front of and to each
side of the heat pump is maintained.
6.2 Sound Emissions
The heat pump offers silent operation due to efficient
sound insulation. Noise transmission to the
foundation or the heating system is largely prevented
by internal decoupling measures.
