Storage of produce in the refrigerator
* Produce should be placed in boxes or in containers. Place contents on the she-
lves. Make sure the contents do not touch the back wall, this could lead to frosting or
wetting of the products.
* Do not put any containers with hot content into the refrigerator.
* Make sure you mark the packages for easier identication of the content and take
down the date of the freezing.
* The packaging should be tight and stick to the frozen product. Do not use glass
packaging in the freezer compartment.
* Freeze products divided into small portions for single use and / or examination..
* Depending on the quantity of the produce to be frozen, follow the instructions below.
* Remember that the temperature in the freezing chamber is effected by such factors as
the ambient temperature, quantities of products in the chamber, frequency of opening
the door, amount of frost on the refrigerating elements of the evaporator.
* If you close the freezer door and immediately after it cannot open the door, wait 1 - 2
minutes until the partial vacuum in the freezer is compensated.

The appliance operates in cycles: it refrigerates (frost sets on the back wall during the
phase) and defrosts (water ows down the back wall).
* Turn off the main switch (Photo 4(1)). Unplug the mains cord.
* Always prevent water from getting to the control panel.
* The whole appliance except the door gasket can be cleaned with mild cleaning de-
tergent. The door gasket should be cleaned with water only and wiped dry. Detergents
containing abrasive substances or acids are not suitable for the cleaning.
Defrosting the refrigeration chamber
Frost settles on the back wall of the refri-
geration chamber.
It is automatically removed. During the
defrosting, the condensate can contain
some impurities that could clog up the
opening in the through pipe.. Should it
occur, carefully unclog the opening with
the cleaning plug. (Phot. 5).
Defrosting the freezer
* Bigger deposits of ice on refrigerating surfaces deteriorate the freezer compartment’s
perfor¬mance and increase electricity consumption.
* We advice defrosting the appliance at least 3 or 4 times a year when the level of
contents in the refrigerator compartment is low.
* The defrosting of the appliance should last as little time as possible.
* You can speed-up the defrosting by placing a bowl with hot water on one of the
freezer shelves.
* Do not use an electric heater, heating fan, or a hair dryer to the freezer under any
circumstances.
In order to defrost the freezer chamber:
* Turn off the main switch (Photo 4(1)). Unplug the mains cord.
* Open the freezer door and take out the drawers.
There are locks on the sides of the freezer preventing from accidental fall-out of the
drawers. In order to take a drawer out, you have to pull it home, lift the front slightly
and pull it out in the position.
* Place a at dish or the tray for freezing fruit under the funnel opening to collect the
condensate.
* Do not use sharp objects to scratch-off the ice.
* Wash and dry the inside of the freezer.
* Turn on the appliance according to the relevant section.

Different sounds may be heard during operation. The sounds do not effect correct
operation of the refrigerator.
The sounds that can be heard during normal operation:
* clicks - heard when the control activates or deactivates the compressor
* buzz - the sound of the compressor intensely working shortly after its activation
* crackles and clatter - coming from the cooling system, caused by expansion and shrin-
king of parts due to temperature differences before and after compressor activation
* rustle, gurgle, whistle - coming from the cooling system piping, caused by the coolant
owing inside.
Easily corrigible sources of noise:
* noise caused by the appliance positioned not level - adjust the position with the
adjustable turn-in front feet.
* rubbing the adjacent piece of furniture - move the refrigerator a bit.
* creaking of the drawers and shelves - take out and put back the drawer or shelf.
* sounds of clinking containers / bottles - move the bottles apart.

Maintenance and Service
Energy saving
*Place the refrigerator away from heat
sources (such as radiators and ovens
(Phot.6).
*Make sure air can circulate freely
around the refrigerator, move it away from
the wall at least 1 cm.
*Let dishes cool down before putting
them into the refrigerator, at least to room
temperature.
*Move the frozen food to the refrigera-
tor while defrosting. You will utilize the
low temperature of the frozen food for
cooling
the products gathered in the refrigerator
chamber.
*Defrost when there are ice depo-
sits. Thick layer of ice hampers cold
transition to the food and increases
electric energy consumption.
*Keep the door open as shortly as possi-
ble when putting in or taking out food. The
shorter the time the less ice will deposit
on the evaporator.
the degree the appliance is lled up to.
Knowing that you will not
use the refrigerator for
a longer period of time:
*Set the temperature control dial to „0”
and unplug the appliance.
*Empty the refrigerator and the freezer
compartments (as needed).
*Clean and dry the refrigerator or the
freezer compartment.
Wash carefully all the accessories (vege-
table containers, door
shelves, glass shelves, shelf frames).
*Leave the refrigerator door slightly open
to prevent the chambers from getting
unpleasant smell.
Maintenance
*Periodically, once or twice a year, use
a vacuum cleaner to dust the evaporator
(black bars) located in the back of the
refrigerator. Before the cleaning, set
the temperature control dial to „0” and
unplug the appliance. Make sure you
do not damage the electric wires, the
protection boxes and the capillary tube
while cleaning.
