Technical guide
Floorstanding installation:
■
Use supports for floorstanding installation (accesso-
ries).
■
Where such supports cannot be used, install the out-
door unit freestanding on a solid base of
at least 100 mm height.
■
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
following table.
Wall mounting:
■
Use the wall mounting bracket set (accessories).
■
The wall must meet the structural requirements.
Siting:
■
Never install with the discharge side facing the main
wind direction.
■
Provide wall outlets and protective pipes for the
refrigerant lines and electrical cables without moul-
ded parts or changes of direction.
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.
■
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 the condensate drains off freely.
Create a permanent gravel bed under the outdoor
unit as a soakaway.
■
In regions with prolonged cold seasons, provide an
electric ribbon heater (accessories) for the conden-
sate pan.
Insulation against structure-borne noise and vibra-
tions between the building and outdoor unit:
■
For line entry
above
ground level, fit pipe bends in
the refrigerant lines for vibration compensation: see
"Connecting the refrigerant lines".
■
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.
■
Anti-vibration components are included in the stand-
ard delivery of the brackets for wall mounting and
floorstanding installation. Do not use additional anti-
vibration mounts, springs, rubber mounts, etc.
