Take care of operating the freezer at a position of ther-
mostatic control so that the inside temperature can
never be warmer than -18
o C.
It is practical to make sure of faultless operation of the
appliance daily so as to notice possible failure in time
and prevent deterioration of frozen foods.
Normal operating sounds:
A thermostat controls the compressor and you
will hear a faint click when thermostat cuts in and
out.
You may hear faint gurgling or bubbling sound
when the refrigerant is pumped thorough the coils
at the rear, to the cooling plate/evaporator.
When the compressor is on, the refrigerant is
being pumped round and you will hear a whirring
sound or pulsating noise from the compressor.
The fridge evaporator (this part cool down the
fridge section) is foamed into the cabinet. The
temperature of this part changing during its work,
and parallel with this its dimensions are slightly
changing, too. These changes might cause a
cracking noise, which is natural, harmless phe-
nomenon.
Should you want to check the temperature of food
stored in the refrigerator, set the thermostat knob into
a medium position, place a glass of water centrally in
the cabinet, and put a proper thermometer with an
accuracy of +/- 1 C into it. If after 6 hours you meas-
ure a value b3
o C and +8 o C, the refrigera-
tor works properly. The measuring shall be performed
under steady-stated conditions (without changing the
load).
If the freezer temperature is measured using a ther-
mometer, put it between the products since this will
reflect the real temperature in the frozen products.
Avoid opening the door of frozen food compart-
ment during freezing if possible.
It is not expedient to set the termostat knob to high-
er (e.g. "6") position. Freezing time could be
reduced this way, but the temperature of the fresh food
compartment would go beyond 0
o C permanently, which
would cause freezing to foods and drinks stored there.
Never freeze food in bigger quantity than given
in the "Technical data" at the same time, other-
wise freezing will not be thorough and after dissolv-
ing various deterioration may take place (losing taste
and aroma, lysing, etc.).
Do not make ice during freezing preferably,
bacause making ice reduces freezing capacity.

Storing in the freezer
After finishing freezing it is practical to put the frozen food
from the wire shelf in the frozen food compartment to the
place undar that making room for a next possible freez-
ing. Adjustment of the wire shelf in the frozen food com-
partment ("2" positions) can be used only during storing,
as freezing can be done only at the highest position of the
wire shelf. Food already stored is not damaged by anoth-
er freezing.
(The goods when are put directly on the cooling plate
freeze too fast!)
Do not forget to keep to the storage time given on
the packaging of frozen products if you buy them
frozen.
It is safe to store quick-forzen, frozen foods only if
they have not dissolved even for a short time until
placing them into freezer.
If the deep-frozen food has already dissolved, refreezing
is not recommended, it has to be used as soon as possi-
ble.
How to make ice cubes
To make ice cubes fill the enclosed ice cube tray with
water and put it to the frozen food compartment. Wetting
the bottom of the tray and setting thermostatic control
knob to maximum position can shorten preparing time.
After finishing do not forget to reset the thermostatic con-
trol to the suitable position.
Ready ice cubes can be taken out of the tray under run-
ning water then twist or hit it. If the ice tray freezes to the
compartment, avoid using metal tools or knife to take it
out as the cooling system can be damaged.
Some useful information and
advice
The variable shelves are worth paying attention to,
which increases the usability of the fresh food com-
partment considerably. Rearranging the shelves is
also possible when the door is open at an angle of
90 .
After opening and closing the door of freezer vacuum
will rise inside the appliance because of the low tem-
perature. So wait 2-3 minutes after closing the door
- if you want to open it again - while inner pressure
equalises.
Hints and ideas
In this chapter practical hints and ideas are given about
how to use the appliance to reach maximum energy sav-
ing and there is environmental information about the
appliance as well.
