5.1 General
The air-to-water heat pump 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. If this is not the case, additional
sound insulation measures may be necessary. The heat pump
must be installed in a way that allows maintenance work to be
carried out without hindrance. This is ensured when observing
the distances to solid walls as shown in the figure.
NOTE
º
ºººº
The heat pump is not intended for use above 2000 metres
(mean sea level).
Never install the device in rooms subject to high humidity. Con-
densation can form on the heat pump and air circuit if the hu-
midity exceeds 50 % and the external temperature is below
0°C.
Neither frost nor temperatures higher than 35 °C must occur in
the installation room at any time of the year.
If the heat pump is installed on an upper storey, the load-bear-
ing capacity of the ceiling should be checked. On account of
the acoustics, measures for isolating possible vibrations should
also be very carefully planned in advance as well. Installation on
floors above wooden ceilings is not recommended.
5.2 Condensate pipe
Condensate that forms during operation must be drained off
frost free. To ensure proper drainage, the heat pump must be
mounted horizontally. The condensate pipe must have a mini-
mum diameter of 50 mm and must be fed into a sewer in such
a way that it is safe from frost. Do not discharge the condensate
directly into clearing tanks or cess pits. The aggressive vapours
and a condensate pipe laid in an area which is not frost-free can
destroy the evaporator.
5.3 Sound
To prevent solid-borne sound from being transmitted to the
heating system, we recommend connecting the heat pump to
the heating system using a flexible hose.
Installed air ducts should be sound-isolated from the heat
pump to prevent the transmission of solid-borne sound to the
ducts.
