Installation room requirements

Please note

The installation room must be dry
and free from the risk of frost.
Ambient temperatures of 0 to
35 ºC must be ensured.

Please note

Avoid risk of explosion due to
dust, gases and vapours
in the installation room.

Please note

Observe the permissible floor
load.
■ Align the appliance horizon-

tally.
If the adjustable feet are used
to compensate for an uneven
floor (max. 10 mm), the pres-
sure load on the feet must be
distributed evenly.

■ The total weight must be con-

sidered (see table).
