formation of ammable gas/air
mixtures in the room where the
appliance is located in the event
of a leak in the refrigerant circuit.
WARNING:

Battery backup function
The battery backup system supplies the controller and keyboard with power at power failure.
This makes it possible to supervise the temperatures in the unit during the power failure.
The battery backup system makes it possible to supervise the temperatures for 48 hours.
After a power failure and at the rst start up the battery needs to be recharged. To regain the
full capacity the battery will be reloading for 10 days

is absolutely level sideways.
If the appliance is placed on a soft sur-
face, e.g. oorboards or a carpet you must
recheck whether the appliance is still level
after a period of time as the underlying
surface may yield under the weight of the
appliance.
