5. Using the appliance

• To start the refrigerator connect the plug into a

properly earthed socket.

• The cooling fins should show signs of cooling after

about 3 hours. The refrigerator needs about 6 hours

at normal ambient temperature to reach 6 °C in

the storage compartment.

5.1. Temperature regulation

The usual setting required is in the region of 2 to 3 on

the thermostat knob (Fig. 4), but this can vary with

conditions of load and installation. If it is found

necessary to change the setting, the knob can be

turned to a higher number to give a lower temperature,

or a lower number to give a higher temperature. The

effect of any adjustment can be checked by means of

a thermometer when the refrigerator has reached the

new temperature after some hours.

5.2. Cooling unit control (CUC)

(Ser. No. starting with 637xxxxx or higher.)

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.

7. 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.

8. Defrosting, cleaning and

maintenance

Frost will gradually form on the cooling surfaces and

it must not be allowed to become too thick since it

restricts the cooling.

This frost-formation is kept back by the FUZZY LOGIC

system built into the appliance by switching off the

unit for two hours in every 24 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. (Fig 5)

The defrost water will evaporate automatically into

the circulating air and the vessel will not need

emptying.

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.

6. Ice cubes

Fill the ice tray up to 4/5 with drinking water, and place

the ice tray on the ice-tray shelf. Wipe off any excess

water to prevent the ice tray from freezing to the surface.

To speed up the making of ice cubes, turn the

thermostat to position 5 for a short while. Remember

to turn the dial to its normal setting when the ice cubes

are frozen.

To remove the cubes from the ice tray, hold it under

running water. The ice cubes can now be taken out

easily

8.1. Automatic defrost function

(Ser. No. starting with 637xxxxx or higher)

The first defrosting phase commences 39 hours af-

ter 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.

9. Changing the lightbulb (If available)

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 10-watt bulb can be obtained at any service

shop.
