Installing the external unit
The external unit must always be installed on a firm, vertical and vibration-free surface and secured to some solid material if possible.
Account must also be taken of the prevailing wind direction during the heating season, as the performance of the heat pump will be li-
mited if the external unit is exposed to strong winds.
A windbreak can be installed if required. However, clearance distances as detailed below must be observed.
The following horizontal minimum distances to building components etc. must be observed in order to ensure optimum functioning of
the heat pump.
If it is desired to place the AIR up against the house, it is important that it is placed with consideration for any noise from the outdoor
unit which could be bothering inside.
Locate the AIR unit in such a way that the intake air is drawn from the building's surface. This is because solar heating of the wall during
the day and general heat loss from the building supplies additional energy to the air, which can then improve the efficiency of the heat
pump. If the AIR unit is located with the extract directed at the wall, this will result in cold and damp air being blown against the building,
adding extra energy to the air.
