Please note
Impacts, compression and tensile loads can
cause damage to the outside panels of the
appliance.
Never
apply loads/weight to the top, front or
side panels of the appliance.
!
Please note
If the compressor in the outdoor unit is tilted too
far, lubricant will enter the refrigerant circuit and
damage the appliance.
Max. tilting angle: 45° for approx. 4 min, other-
wise 30°
Installation information
Types of installation:
■
Floorstanding installation with line entry above
ground level
■
Floorstanding installation with line entry below
ground level
■
Wall mounting
Floorstanding installation:
■
Use supports for floorstanding installation (accesso-
ries).
Use ground anchors with a tensile force of at least
2.5 kN to secure the support.
■
Where such supports cannot be used, install the out-
door unit freestanding on a solid base (provided on
site) with a height of at least 100 mm.
■
In difficult climatic circumstances (temperatures
below zero, snow, humidity), we recommend instal-
ling the appliance on a plinth of approx. 300 mm
height.
■
Take account of the weight of the outdoor unit: See
"Specification".
Wall mounting:
■
Use the wall mounting bracket set (accessories).
■
The wall must meet the structural requirements.
Use suitable fixing materials, depending on the wall
structure.
Siting:
■
Never install with the discharge side facing the main
wind direction.
■
Do not mount the outdoor unit above cellar shafts or
floor troughs.
■
Provide wall outlets and protective conduits for the
hydraulic connection lines and electrical connecting
cables without moulded parts or changes of direc-
tion.
Weather influences:
■
Observe wind loads when installing the unit on sites
exposed to the wind.
Where outdoor units are installed on a flat roof, con-
siderable wind loads may occur, depending on the
relevant wind load zone and height of the building.
For such installation situations we recommend hav-
ing the substructure sized by a design engineer in
accordance with DIN 1991-1-4.
■
Provide thermal insulation of sufficient thickness on
the pipework to the outdoor air: See following table.

Thermal conductivity
■
Incorporate the outdoor unit into the lightning protec-
tion system.
■
Consider the heat absorbed (heating mode) and heat
emitted (cooling mode) by the appliance when
designing weatherproofing measures or an enclo-
sure.
Condensate:
■
Ensure that condensate can drain freely.
Create a permanent gravel bed under the outdoor
unit as a soakaway.
■
In regions where the outside temperature regularly
falls below 0 °C we recommend fitting an electric rib-
bon heater (accessories) for the condensate pan of
the outdoor unit.
Structure-borne noise insulation and vibration iso-
lation between the building and outdoor unit:
■
Route cables/leads between the indoor and outdoor
units free of stress.
■
Installation only on walls with a high weight per unit
area (> 250 kg/m
2
); in other words not on lightweight
walls, roof structures, etc.
■
Vibration isolation components are included in the
standard delivery of the wall mounting brackets.
For floorstanding installation, only use the rubber
mounts supplied.
Do not use additional anti-vibration mounts, springs,
rubber mounts, etc.
