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 make full 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 installed to allow easy
maintenance/service access. This is ensured if
a clearance of approx. 1 m in front of the heat
pump is maintained.
6.2 Sound Emissions
The heat pump offers silent operation due to efficient
sound insulation. Any sound transmission to the
foundation or the heating system can be largely
prevented by internal sound decoupling measures.
CAUTION!
MOUNTING
7.1 General Information
The following connections need to be estab-
lished on the heat pump:
- supply/return flow of the brine system
- supply/return flow of the heating system
- power supply
7.2 Connection on Heating Side
The heating system must be flushed
prior to connecting the heat pump.
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, as well as residues of sealing
material, and the like. Any accumulation of deposits
in the condenser may result in a total failure of the
heat pump.
Once the installation on the heating side has been
completed, the heating system must be filled, de-
aerated and pressure-tested.
The sensor supplied loose in the control box must
be fitted as shown in the block diagram.
Heating water minimum flow rate
The heating water minimum 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 a differential pressure-free
manifold or an overflow valve. The procedure for
setting an overflow valve is described in the Chapter
Commissioning.
Frost protection for installations prone to frost
Provided the controller and heating circulating
pumps are ready for operation, the frost protection
feature of the controller is active. If the heat pump
is taken out of service or in the event of a power
failure, the system has to be drained. In heat pump
installations where a power failure cannot be readily
detected (holiday house), the heating circuit must
contain a suitable antifreeze product.
