■ Condensate:
– Ensure that the condensate drains off freely.
To create a permanent gravel bed below the outdoor unit as a
soakaway: See page 103.
– In regions where the outside temperature regularly falls below
0 °C we recommend fitting an electric ribbon heater (accesso-
ries) for the condensate pan of the outdoor unit.
■ For insulating against structure-borne noise and vibrations
between the building and outdoor unit:
– Route connecting cables between the indoor and outdoor units
free of stress.
– Installation only on walls with a high weight per unit area
(> 250 kg/m
2
), i.e. not on lightweight walls, roof structures, etc.
– Anti-vibration components are included in the standard delivery
of the wall mounting brackets.
– For floorstanding installation, only use the rubber mounts sup-
plied.
– Do not use additional anti-vibration mounts, springs, rubber
mounts, etc.
