Selecting the installation site

▶
The installation site must be below 2000 metres above
sea level.
▶
Select a dry room that is frost-proof throughout and in
which the maximum installation height is not exceeded
and the environmental temperature is neither above nor
below the permitted range.
–
Permissible relative air humidity: 40 ... 75 %
▶
Ensure that the required minimum clearances can be
maintained.
▶
The permissible height difference between the indoor unit
and outdoor unit must not be greater than 15 m.
▶
When selecting the installation site, you must take into
consideration that when the heat pump is in operation, it
will transfer vibrations to the walls.
▶
Ensure that the wall is even and offers sufficient load-
bearing capacity to bear the weight of the product.
▶
Ensure that the pipes are routed appropriately.
▶
Do not install the product above another unit that may
damage it (e.g. above a cooker that produces water va-
pour and grease) or in a room with a high level of expos-
ure to dust or in a corrosive environment.
▶
Do not install the product below a unit from which liquids
may flow.
