5.5. CHANGE DEFROST PARAMETERS
If you wish to return to the compartment temperature display,
either press the ON key or wait 10 seconds. Note that doing
so, any changes made WILL NOT be saved.
1. Press the SET and
selected parameter is displayed).
2. Press either the - key or + key to change the parameter (see the
complete list below). The display starts flashing.
3. Press the SET key to validate the change.
For multi-temperature units, this procedure is the same for
both compartments but must be carried out individually.
For eutectic units, the compartment fitted with eutectic
plates has its setpoint locked and can only operate at
freezing temperatures. Defrost related parameters are also
locked.

5.6. DEFROST THE EUTECTIC COMPARTMENT
Frost gradually builds up on the eutectic plates. Unlike a regular
evaporator, the defrost sequence is not automatic, but is still crucial
for proper operation, which is why the unit must be defrosted man-
ually on a regular basis.
Failing to perform proper defrost as described below, will re-
sult in poor unit performance.
Never use hot water or any flammable source to defrost eu-
tectic plates, as this could damage the system and present
a safety risk for you and your surroundings.
Frost build-up can be avoided by brushing the plates regu-
larly.
1. Stop the unit.
2. Open the box doors and wait for the plates to defrost naturally
(duration varies from 3 to 12 hours depending on ambient
condition).
WARNING
WATER WILL REMAIN ON THE FLOOR OF THE
COMPARTMENT AFTER DEFROSTING, POSING A
RISK OF SLIPPING. MOVE CAREFULLY AROUND
THE UNIT AND DRAIN OFF ANY REMAINING WA-
TER, TO PREVENT IT FREEZING ON THE FLOOR.
