■ In regions with prolonged cold sea-
sons (e.g. in Germany), provide an
electric supplementary heating facility
(accessory) for the condensate pan.
■ For insulation of structure-borne noise
and vibrations between the building
and the external unit, consider the fol-
lowing measures:
– When cable entry is
above
ground
level, fit pipe bends as anti-vibration
mounts in refrigerant lines (see
"Connecting 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 structure etc.
– When installing the unit on the floor,
use only the rubber mounts sup-
plied; for wall mounting use the anti-
vibration mounts supplied with the
wall mounting bracket set; never use
additional anti-vibration mounts,
springs, rubber buffers etc.
