Requirements for the installation room
!
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
account of the total weight of the appliance: See
chapter "Pressure points".
Minimum room volume (to EN 378):
According to EN 378, the minimum volume of the
installation room depends on the refrigerant charge
and composition.
