Installation requirements
■
Provide a manual drain for the heating water flow
and return lines in any area at risk from frost.
If the heat pump control unit and heating circuit
pump are ready for operation, the frost protection
function of the heat pump control unit is enabled.
Drain the system if the heat pump is shut down or
there is a prolonged power failure.
On heat pump systems where a power failure cannot
be recognised (holiday home), operate the heating
circuit with a suitable antifreeze or drain it.
■
To prevent "air short circuits" and an increase in
noise level due to reflection, avoid siting equipment
in recesses, at building corners or between 2 walls.
Lawn areas and vegetation can reduce noise gener-
ation.
Therefore,
only the heat pump foundations should
be made from reverberant material (concrete).
■
Never install the heat pump next to living rooms or
bedrooms.
■
The air in the discharge area is approx. 10 K colder
than the ambient air. Therefore, black ice could
develop in the discharge area even at [ambient] tem-
peratures above freezing. A clearance of
≥
3 m must
be observed to pavements or patios.
Note
During defrosting, cool vapour escapes from the heat
pump air discharge vents. This vapour build-up must
be taken into consideration during installation (choos-
ing the installation location, orientation of the heat
pump).
