ATTENTION
For safety reasons:
Never disconnect the unit from the power sup-
ply, unless the unit is being opened.
ATTENTION
Install the heat pump only indoors and operate
only with outside air as the heat source. The air
ducts must discharge into the open air. Do not
restrict or block the air ducts.
Dimensional drawing and installation plan for
respective model.
WARNING!
Switch on unit only if air ducts are
mounted on the unit.
Take measures on the fan side to pre-
vent injuries from the rotating fan (above-
ground air duct discharge: weather grille,
below-ground air-channel discharge: rain
guard – accessories not included in scope
of delivery).
ATTENTION
The integration of the heat pump in ventila-
tion systems is not permissible. The use of the
cooled air for cooling purposes is not permitted.
ATTENTION
The ambient air in the location where the heat-
ing pump is installed and also the intake air which
is used as a source of heat must not contain any
kind of corrosive components!
Components such as ammonia, sulphur, chlo-
rine, salt, sewer gas, ue gases etc. may cause
damage leading to complete failure or even a to-
tal write-off of the heating pump!
CAUTION!
In the air outlet area the air temperature
is ca. 5 K below the ambient temperature.
Under certain climatic conditions, there-
fore, an ice layer can form in the air out-
let area. Install the heat pump so that the
air blower does not blow in the direction
of footpaths.
