Please note
Unfavourable ambient conditions can lead to
malfunctions and appliance damage.
The installation room must be dry and free from
the risk of frost:
■ Ensure ambient temperatures between 0 and
35 °C.
■ Max. 70 % relative humidity (corresponds to
an absolute humidity of approx. 25 g water
vapour/kg dry air)
Danger
Dust, gases and vapours can be damaging to
health and trigger explosions.
Avoid dust, gases and vapours in the installation
room.
!
Please note
Overloading the floor can result in damage to
the building structure.
Observe the permissible floor load. Take the
total weight of the appliance into account.
