Operation and Function
Refrigerator section
The thermostat button can be set from 1(min.) to 7(max.). A suitable setting must be
found by trial and error. Start by setting the button to 4. Check the temperature, then
adjust the setting upwards or downwards as required. Usually, a temperature of 41°F
(5°C) is recommended for items stored in a refrigerator. To check the temperature,
place a thermometer in a glass of water positioned in the center of the cabinet for 12
hours. An average temperature of 41°F should be found in the center of the cabinet.
Freezer section
Always maintain a correct storage temperature.
The thermostat button can be set from 1(min.) to 7(max.). A temperature of 0°F
(-18°C) is recommended for items stored in a freezer. (Maintaining a temperature lower
than this consumes additional energy.) The temperature in the freezer is displayed on
the thermometer.
The control lamp lights green when the power supply is connected correctly.
The control lamp lights yellow when Super Freeze is activated.
The indicator lamp lights red and the acoustic alarm sounds if the temperature in the
freezer is too high. To switch off the acoustic alarm, set the freeze button to O(see
fig. 12). The indicator lamp continues to light red as long as the temperature in the
freezer remains too high.
When starting the freezer for the first time, switch off the acoustic alarm by setting the
freeze button to O. Once the recommended temperature (0°F, or -18°C) has been
achieved in the freezer, set the freeze button to the symbol. This will allow the
acoustic alarm to sound if the temperature in the freezer becomes too high.
It is normal that the indicator lamp lights red when the freezer is started for the first time.
It will also occasionally light red when large quantities of fresh material are put in the
freezer simultaneously.
fig. 12

Glass shelves
The shelves are made of tempered glass and can be repositioned within the cabinet. To
move the shelves, the door must be opened 90°. To remove a shelf, pull it forwards and
lower it. The shelf can then be removed and placed in the desired position. From the top
and downwards.
Storage boxes
The storage boxes can either be placed in the door
or on the glass shelves. Their tight-fitting lids
prevent the products stored in them from drying out
and saves the need for further packaging.
Bottle rack
The bottle rack is ideal for both large and small bottles.
Bins
The shelf above the bins functions as a lid, maintaining humidity and preventing
the items stored in the bins from drying out.
Glass shelf with slide damper
The slide damper above the crisper bins allows
the temperature and humidity in the bins to be
regulated.
Opening the damper reduces the temperature
and humidity.
Closing the damper increases the temperature and humidity.
Shelves in the door
The shelves in the door are practically positioned with the
box shelf at the top and door shelves at the bottom. They
provide ample space for storing large and small items.

Defrosting
Automatic defrosting of refrigerator section
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.
Defrosting the freezer
The items stored and the humidity of the air gradually cause frost and ice to form in the
freezer. A thin layer of frost or ice does not affect freezer performance, but the thicker
the layer, the higher the energy consumption. Loose frost can be removed using a
plastic or wooden scraper.
Never use a knife or other sharp implement that might damage the inside of the freezer.
When the layer of frost and ice exceeds 1/4 inch, the freezer should be completely
defrosted.
Proceed as follows:
1. Switch the freezer off.
2. Pull out the drain spout at the bottom of the cabinet and place a bowl under it to
collect defrost water (fig. 16). If the spout is frozen in place, lay a cloth which has
been soaked in hot water over it for a few minutes.
3. Remove the items.
4. Place a bowl of hot (but not boiling) water in the freezer.
5. To prevent the floor from becoming wet during defrosting, check progress from time
to time and lay towels around the bowl on the floor to protect against ice and
splashes. When all the frost and ice have melted, clean the inside of the cabinet with
a mild detergent solution. Dry the freezer with a soft cloth.
6. Restart the freezer.
7.

Cleaning and Maintenance
Cleaning
Disconnect the power supply before cleaning the inside of the cabinet.
The cabinet is best cleaned using warm water (max. 150°F) with a little mild 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 defrost water channel, in which condensation from the evaporator runs, is located
on the rear wall of the cabinet and must be kept clean. Add a few drops of disinfectant
to the defrost water drain a couple of times a year, and clean the drain using a pipe
cleaner or the like. Never use sharp or pointed implements.
The sealing strip around the doors must be cleaned regularly to prevent discoloration
and prolong service life. Use clean water. After cleaning the sealing strip, check that it
continues to provide a tight seal.
Dust collecting on the compressor and in the compressor compartment is best removed
using a vacuum cleaner. It is possible to clean beneath the appliance by removing the
kick plate.
Stainless steel or aluminum doors are best cleaned using a soft cloth with a spray made
for cleaning metallic surfaces. Various suitable products are available from most house-
hold appliance distributors.
If the appliance is not to be used for any length of time, switch it off, empty it, clean the
cabinet and fittings, and leave the doors slightly open to allow air circulation and prevent
smells.
Replacing the light bulb
Unscrew the bulb without removing the shade.
Bulbs with an output of more than 12 W must not
be used.
