thermometer when the refrigerator has reached the new
temperature after some hours.

5.2. Cooling unit control (CUC)

The electronic checks the function after every defrosting
period (every 24 hours) by measuring the evaporator
temperature drop. If it registers a problem the refrigerator
will shut down and stops cooling. If this happens you should
check whether the refrigerator has been overloaded, that
the door was properly closed, that the cooling unit
ventilation is correct and that the refrigerator is levelled.
After checking, unplug the refrigerator at least for 10
seconds and plug it in again. This resets the unit and it will
function again. If no sign of cooling there is a problem with
the cooling unit and you should contact Dometic service.
6. Useful suggestion
Do not overfill the appliance.Put warm foods and drinks in
the appliance only when they have cooled down to room
temperature. It is advisable to leave some space between
the products in the cabinet to ensure efficient and even
cooling. If the shelves are packed too tightly there may be
unacceptable temperature variations.
7. Defrosting, cleaning and
maintenance
Frost will gradually form on the cooling surfaces and it must
not be allowed to become too thick since it acts as an
insulator and interferes with the cooling.
This frost-formation is kept back by the FUZZY LOGIC
system built into the appliance. The first defrosting phase
commences 39 hours after the start and lasts for two
hours. After this, the device operates for 22 hours at a time,
followed by a defrosting period of 2 hours.
The frost will melt and the defrost water will run through the
drain tube from the drip channel into an evaporating vessel
located at the bottom rear of the refrigerator at all models.
(Fig. 6.) The defrost water will evaporate automatically into
the circulating air and the vessel will not need emptying
manually.
If we want to switch off the unit, turn the thermostat knob to
"0", disconnect the refrigerator from the electricity supply
and leave the cabinet door open. After defrosting the

cabinet interior should be wiped out with a clean, damp
cloth.
In the case of increased air humidity, frost may form on
the cooling ribs. Should the frost layer attain a thickness
of approximately 3 mm, the refrigerator must be
defrosted to avoid impairing the performance level.

8. Changing the lightbulb

If the lightbulb needs changing, pull out the plug and
proceed as follows:
Press the metal reflector to one side and draw the lamp
covering backwards. Replace the bulb and push the
covering back into place.
A new max. 10-watt bulb can be obtained at any service
shop.

9. Reversing the door hang

The direction the door opens can be transferred from
one side to the other by carrying out the following steps:
disconnect the mains
lay the refrigerator down carefully on its back
remove the lower hinge
remove the two upper left-hand screws and detach
the covering plate by pulling it forward
detach the upper hinge and mount it on the opposite
side
remove the hinge bolt and screw it in from below
insert the covering plate in the upper right-hand
corner by pushing it in and secure it with the two
screws
position the door on the upper hinge bolt and mount
the lower hinge
ensure the door can move freely and the seal is
correctly positioned.
