Installation information
Types of installation:
■ Floorstanding installation with line
entry above ground level
■ Floorstanding installation with line
entry below ground level
■ Wall mounting
Technical guide
Floorstanding installation:
■ Use supports for floorstanding instal-
lation (accessories).
■ Where such supports cannot be used,
install the external unit freestanding on
a solid base of at least 100 mm height.
■ In difficult climatic circumstances
(temperatures below zero, snow,
humidity) install the appliance on a
plinth of approx. 300 mm height.
■ Take into account the weight of the
external unit: See the following table.
Wall mounting:
■ Use the wall mounting bracket set
(accessories).
■ The wall must meet the structural
requirements.
Positioning:
■ Never install with the discharge side
facing the main wind direction.
■ Provide wall ducts and protective
pipes for the refrigerant lines and elec-
trical cables without moulded parts
and change of direction.
Weather influences:
■ Observe wind loads when installing
the unit on sites exposed to the wind.
■ Incorporate the external unit into the
lightning protection system.
■ Consider the heat emitted by the unit
when planning your weatherproofing
or an enclosure.
Condensate:
■ Ensure the condensate can drain
freely, and create a permanent gravel
bed below the external unit as a soak-
away.
■ In regions with prolonged cold sea-
sons (such as Sweden for example),
provide an electric ribbon heater
(accessory) for the condensate pan.
Insulation against structure-borne
noise and vibrations between build-
ing and external unit:
■ When line entry is
above
ground level,
fit pipe bends in the refrigerant lines for
vibration compensation: See "Con-
necting refrigerant lines".
■ Route electrical cables/leads between
the internal and external units free of
stress.
■ Installation only on walls with high
weight per area (> 250 kg/m
2
), in other
words not on lightweight walls, roof
structures etc.
■ For floorstanding installation, only use
the rubber mounts supplied.
■ For wall mounting, only use the anti-
vibration mounts from the bracket set.
■ Never use additional anti-vibration
mounts, springs, rubber mounts, etc.
