BATTERY BACKUP SYSTEM
Some models are equipped with a battery back up system. The 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 50 hours. After a power failure and at the first start up the battery needs to
be recharged. To regain the full capacity the battery will be reloading for 10 days

AUTOMATIC DEFROSTING.

The refrigerator is defrosted automatically. Defrost water runs through a pipe and is collected in
a tray above the compressor where the heat generated by the compressor causes it to
evaporate. The defrost water tray should be cleaned at intervals.

CLEANING AND MAINTENANCE

Before cleaning, disconnect the power supply and remove all loose fittings.
The appliance is best cleaned using warm water (max. 65°C) with a little mild, perfume-free
detergent. Never use cleaning agents that scour.
Use a soft cloth. Rinse with clean water and dry thoroughly. It is important to prevent water
from entering the control panel.
The sealing strips around the door must be cleaned regularly to prevent discolouration and
prolong service life. Use clean water. After cleaning the sealing strip, check that it continues to
provide a tight seal. It is recommended that the wire and tubular condensers on the rear of the
appliance be cleaned.
The ventilation grille, the condenser, the compressor and the compressor compartment must
also be kept free of dust and dirt. Clean it with a vacuum cleaner regularly.
Remove the lower panel from beneath the door by loosening the two screws. Do the same on
the back (see fig. 12)
