5.4 Installation in coastal areas

If the unit is installed close to the sea, the high salt concentra-
tion can lead to increased corrosion. If necessary, the mainte-
nance intervals must be adapted to the local conditions. The re-
sponsibility for heat pump installation lies with the specialist
system construction company. Local requirements such as
building regulations, static load of the building, wind exposure
etc. must be taken into account.
NOTE
If the outdoor unit is installed in a coastal area, direct sea wind
must be avoided.
Case 1: If the outdoor unit is installed in a coastal area, direct
sea wind should be avoided. Install the outdoor unit in the op-
posite direction to the sea wind.

Case 2: If the outdoor unit is installed in the direction of the sea
wind, set up a wind guard to catch the sea wind.
 The wind guard must be robust enough to catch the sea
wind (e.g. made from concrete).
The height and width of the wind guard must correspond

to at least 150% of the outdoor unit.
A distance of at least 700 mm from the outdoor unit must

be maintained to guarantee sufficient air flow.

NOTE
Dust or salt soiling on the heat exchanger should be regularly
cleaned (at least once a year) with running water.

NOTE
The use of heat pumps is safe from a distance of 12 km from
the sea with a maximum salt content of 3.5%
If the heat pump is installed on the rear side of a building facing
away from the sea, the required minimum distance is halved
For waters with low salinity, the following calculation formula
may be used:
Minimum distance =
The minimum distance if installed on the Baltic Sea with a salt
content of 1.5%, for example, would be 5.14 km. This could be
reduced to 2.5 km if the heat pump was on the rear of the build-
ing facing away from the sea.
CAUTION!
Incorrect installation, maintenance or repair can result in
damage to property and personal injury.
5.5 Precautions in winter and in
In snowy areas or extremely cold locations, adequate pro-

tective measures must be taken to guarantee that the unit
continues functioning correctly.
 Install the outdoor unit such that snow cannot fall directly
on the unit. If snow collects on the air inlet and freezes,
malfunctions could occur.
When installing the outdoor unit in areas where there is a

lot of snowfall, ensure the unit is installed at least as high as
the level of an average snowfall (average annual snowfall).
If more than 100 mm of snow collects on the outdoor unit,

the snow must be removed prior to operation.
NOTE
The intake and outlet opening of the outdoor unit should not
be positioned against the wind if possible.
