Air-to-water heat pump 6 kW
5.2 Indoor unit
The indoor unit must be installed in a frost-free, dry room on an
even, smooth and horizontal surface. The entire base of the
frame should lie directly on the floor to ensure an adequate
soundproof seal. The surface must have sufficient load bearing
capacity for the weight of the heat pump and the domestic hot
water quantity.
The indoor unit must be installed so that maintenance work can
be carried out without hindrance. This can be ensured by main-
taining a clearance of approx. 1 m in front of and to the right of
the heat pump.
Neither frost nor temperatures higher than 35 °C must occur in
the installation location at any time of the year.
The minimum volume of the room where the heat pump is in-
stalled must be no less than the following value depending on
the refrigerant quantity in the device:
If the refrigerant quantity is increased, the room volume must
be calculated according to the following formula:
[minimum permissible room volume m³] =
[refrigerant quantity in kg] / [permissible concentration
0.39 kg/m³]
5.3 Acoustic emissions
The heat pump operates silently due to efficient sound insula-
tion. Internal insulation measures should be carried out to pre-
vent vibrations from being transmitted to the foundation or to
the heating system.
