Siting requirements

!
Please note
Prevent damage to the appliance
during handling.
Never put weight on the top, front
or side panels of the appliance.
Requirements of the heat pump installation site
The heat pump may only be sited out-
side the building on solid foundations
(see page 9).
■ Provide a manual drain for the heating
water flow and return lines in any area
at risk from frost.
Drain the system if the heat pump is
shut down or there is a prolonged
power failure.
■ If the heat pump control unit, secon-
dary pump and heating circuit pumps
are ready for operation, the frost pro-
tection function of the heat pump con-
trol unit is enabled.
In heat pump systems where a power
failure would not be detected, e.g. hol-
iday home: operate the heating circuit
with a suitable antifreeze or drain the
heating circuit.
Requirements for the heat pump control unit installation location
The heat pump control unit may only be
installed inside the building on a wall
(see page 26).

Please note
Tilting the compressor at a steep
angle inside the heat pump can
result in appliance damage.
Max. tilting angle 45 °
■ To prevent an increase in noise level
due to reflection, avoid siting equip-
ment in recesses, at building corners
or between 2 walls.
■ Lawn areas and vegetation can
reduce noise development. Only the
heat pump foundations should there-
fore be made from reverberant mate-
rial (concrete).
■ Never install the heat pump next to liv-
ing rooms or bedrooms.
■ The air in the discharge area is approx.
10 K colder than the ambient air.
Therefore, black ice could develop in
the discharge area even at [ambient]
temperatures above freezing. Clear-
ance to paths or patios: ≥ 3 m
