· This is especially important if you have an upright
model.
· Check periodically if the appliance is provided with
sufficient cooling (undisturbed circulation of air
through the bottom rail openings).
· Turn the thermostat knob from higher to lower
setting as soon as possible (depends on how loaded
the appliance is, ambient temperature...)
· Never use continuous operation unless unnecessarily
required; switch the operation mode selection switch
to the setting for automatic operation as soon as
possible.
· Before freezing packages of fresh foods, make sure
they are cooled to ambient temperature. (except for
the soup)
· Ice and frost layer increase energy consumption, so
do clean the appliance as soon as the layer is 3-5
mm thick.
· If the gasket is damaged or if it turns out that the
sealing is poor, the energy consumption is
substantially higher. To restore efficiency, replace
the gasket.
· Condenser at the bottom of the appliance must
always be clean and dust free (see Section Cleaning
of the Appliance).
· Always consider instructions stated in sections
Positioning and Energy Saving Tips, otherwise the
energy consumption is substantially higher.
If you've bought this appliance to replace an old one
equipped with a lock that cannot be opened from
inside (lock, bolt), make sure that the lock is broken.
This will make it impossible for the children to lock
themselves in the appliance and suffocate.
· Mind to connect the appliance correctly to the mains
supply (see Connection to the Mains Supply).
· Do not touch the cooled surfaces while the appliance
operates, especially not with wet hands, because the
skin might stick to the cold surfaces.

· Do not freeze bottled drinks, especially not fizzy
ones such as mineral water, sparkling wine, beer,
cola etc., because liquid expands during freezing and
the glass bottle is very likely to blow up.
· Never try to eat frozen food (bread, fruit,
vegetables), because you may get frostbites.
· Carefully check the foods for color and smell and if
you are in doubt about their quality, throw them
away because they may be spoiled and therefore
dangerous to eat.
· Disconnect the appliance from the mains before
repairing (only a qualified technician should repair it)

system inside the appliance. Do not use sharp object
for defrosting the appliance. Use only enclosed tools
or tools recommended by the manufacturer.
· The refrigerating system of the appliance is filled
with refrigerant and oil, so when the appliance is
damaged, handle it with care and dispose it of in
compliance with environmental protecting
precautions. (See We Care for the Environment).
· Heating element incorporated in the appliance, all
around the rim, is controlled by the operation of the
compressor and it prevents the door gasket to freeze
on to the freezer housing.
· In the supply cord is damaged, it must be replaced
by the manufacturer or his service agent or a
qualified person in order to avoid hazard.
· The rating plate is in the interior or on the rear wall
of the appliance.

Place the appliance in dry and well ventilated room.
Allowed ambient temperature depends on the model
(class) of the appliance and is stated on the rating
plate of the appliance. Never place the appliance near
heat emitting devices (e.g. cooker, radiator, water
heater and similar devices) and do not expose it to
direct sunlight.
The appliance should be positioned at least 3 cm away
from the electric or gas cooker and at least 30 cm
away from the oil or coal stove. If this is not possible,
use an appropriate insulation.
Class Ambient temperature
SN (sub-normal) from + 10°C to + 32°C
N (normal) from + 16°C to + 32°C
Connect the appliance with the cable and plug to the
power supply socket outlet with a ground terminal
(safety socket).
Required nominal voltage and frequency are indicated
on the rating plate.
The connection to the mains supply and earthing have
to be made according to current standards and
regulations. The appliance resists temporary voltage
tolerance up to -6 to +6 %.
The appliance is equipped with four adjustable legs, so
that the height may be adjusted from 82 to 90 cm.

The freezer is controlled with switches and thermostat
button, incorporated in the bottom section of the appli-
ance.
1ON/OFF switch (green signal lamp)
2Continued operation button (yellow signal lamp)
3Alarm off button (red signal lamp)
The appliance is switched on - the green light is on.
The appliance is switched off - the green light is off.
This switch is used to select one of the two operation
modes: continuous and automatic.
Continuous operation - the yellow light is on.
The cooling system operates continuously. This mode
is selected when you want to freeze large amounts of
fresh foods and in case you want to deep freeze
already frozen foods.
Automatic operation - the yellow light is off.
The interior temperature is controlled by the thermo-
stat which turns the cooling system on and off.
The frequency of switching the cooling system on and
off depends on:
- the thermostat knob position (thermostat setting),
- how often you open the door; and
- ambient temperature.

The sound of the alarm is switched off by pressing the
Alarm Off button. The alarm goes off because of high
temperature inside the freezer (red signal lamp is on),
or because of the excessive dust collected at the con-
denser (red signal lamp is off).
Consult the Section Troubleshooting Guide
When the freezer operates automatically, the interior
temperature is controlled by the thermostat.
The most suitable thermostat position is in the middle
between max (7) and min (1).
We recommend setting the thermostat on positions
towards max (7) only in case you want to accelerate
cooling, as for example before loading smaller amounts
of fresh foods or when the operation mode shall corre-
spond to the ambient temperature.
Thermostat settings towards min (1) help you save
energy provided that the freezer is loaded with smaller
amount of frozen foods.
Changes of the ambient temperature affects tempera-
ture in the interior of the appliance. Choose correct
setting of the thermostat knob.

operation position. All three signal lamps are on. Place
fresh food into the freezer several hours after the red
signal lamp goes off.
Proper use of the appliance, adequately packed food,
correct temperature and taking into account hygienic
precautions will substantially influence the quality of
freezing the food or storing of the frozen foodstuffs.
· Carefully select food to be frozen: it should be of
adequate quality and suitable for freezing.
· Choose correct packaging for each kind of food and
pack it correctly.
- The packaging should be air tight and well sealed
without leaking since this could cause substantial
vitamin loss and dehydration.
- Foils and bags should be soft enough to tightly wrap
around the food.
· Mark packages with following data: kind and amount
of foods and the date of loading.
· It is most important that the food is frozen as
quickly as possible. We therefore recommend the
size of the package not to be too large and to be
cooled before loading into the freezer.
· The amount of the fresh foods that can be loaded in
the freezer within 24 hours is stated on the rating
plate. If the loaded amount is too large, the quality
of freezing is reduced which affects the quality of
frozen foods.
Freeze the food in the freezing compartment (see
Section Description of the Appliance)
· 24 hours prior freezing of fresh food switch the

continued operation button (2) to the uninterrupted
operation (yellow lamp is on). At the end of this
period load fresh food into the freezing compartment.
· After 24 hours move the frozen food to the storage
compartment of the freezer and repeat the freezing
procedure with new load if required. Fresh food
should not touch the already frozen packages.
· Approximately 24 hours after the last loading of
fresh food press the continued operation button
again (2) and switch to the automatic operation
(yellow signal lamp is off).
· In case of freezing minor quantities of fresh food
(1-2 kg), it is not necessary to switch the appliance
to the continued operation mode (2).
Store the already frozen food in the storage
compartment of the freezer. The bottom basin of the
appliance is also intended for storage purposes.
Storage baskets may be removed at random and food
may be placed directly upon the cooling shelves.
The storage time and recommended temperature for
storing commercially frozen foods is indicated on the
packaging. For storing and use consider
manufacturer's instruction.
When shopping, be careful and choose only packages
of foods which are adequately packed and provided
with complete data and stored in freezers where the
temperature is not higher than -18°C.
Do not buy packages of food wrapped with frost. This
indicates that the package was thawed before at least
once. Take care that packages don't start to thaw.
Temperature rise shortens the storage time of
commercially frozen foods.

Approximate Storage Time of Frozen Foods
Partially thawed or defrosted foods should be used as
soon as possible. Cold air preserves the food but it
does not destroy microorganisms which rapidly
activate themselves after defrosting and make foods
perishable.
Partial defrosting reduces the nutritional value of
foods, especially of fruits, vegetables and ready-made
meals.

Frost and ice layer, depositing on the inner walls of
the freezer should be defrosted when 3-5 mm thick.
· 24 hours prior defrosting press the continued
operation mode button (2) (yellow lamp is on) to
provide extra low temperature of food inside the
freezer. After this period take the food out and
protect them from melting.
· Disconnect the appliance from the mains supply.
· Avoid using defrosting sprays, as they may cause
damage to the plastic parts and may be hazardous to
health.
· Water collected at the bottom basket of the
appliance should be mopped with a sponge or highly
absorbing cloth.
Before cleaning the appliance disconnect the cable
from the mains supply. Do not use abrasive cleaning
agents.
· Clean the exterior of the appliances with water and
liquid detergent.
· Wash the interior with lukewarm water and some
vinegar.
· The air openings in the bottom rail should be cleaned
or vacuumed periodically.
· Sound alarm signals the excessive dusting of the
condenser. The alarm may be switched of by the
alarm off button (3).
Dust from the condenser should be vacuumed in the
following manner:
- push the finger through the opening in the bottom
rail and release the fastener;
- pull the rail towards you and remove it;
- remove the bottom board of the kitchen cabinet;
- pull the condenser dish out;
- use the vacuum cleaner to clean the dust from the
condenser;

- replace the condenser dish and the bottom rail in the
opposite order.
After you have cleaned the appliance, reconnect it to
the mains supply and put the food packages back to
their place.
In order to optimize the operation of the appliance and
save energy, it is recommended to clean periodically
the dust from the condenser at the back of the
appliance.
Disconnect the appliance from the mains prior the
commencement of cleaning!
· Empty the contents of the appliance.
· Remove the supporting panel from the bottom of the
kitchen cabinet.
· Remove the screws fixing the appliance to the
kitchen worktop.
· Pull the appliance out and expose the condenser at
the back of the appliance.
· Unscrew the screws from the condenser bonnet and
remove the bonnet.

During the service, you can come across some trou-
bles that in most cases result from improper handling
of the appliance and can easy be eliminated.
· Check the voltage in the socket and see if the
appliance is switched on (green signal lamp is on).
If the temperature within the freezer is too high, it is
signaled by the red signal lamp and the sound alarm,
which may be switched off by pressing the alarm off
button (3). When the lamp goes off the interior of the
freezer has again reached the appropriate temperature.
Another increase of temperature within the freezer is
again signaled both by the red lamp and the sound
alarm.
The reasons for this may be the following:
· The door was frequently opened or it was left
opened for too long.
· The door is not properly closed (the door may sag,
the gasket may be polluted or damaged).
· Power supply has been interrupted for a longer
period of time.
· Perhaps you have overloaded the appliance with
fresh foods.
Excessive dust on the condenser or around the air cir-
culation openings in the bottom rail may set off the
sound alarm. It may be switched off by pressing the
alarm off button (3).
Clean the condenser and the air circulation openings in
the bottom rail (consult the Section Cleaning of the
Appliance).

· Continued operation mode is on (yellow lamp is on).
Press the button (2) and switch the continued
operation mode off (yellow lamp goes off).
· Insufficient cooling of compressor and condenser.
This is signaled by the sound alarm.
Check the air circulation through the bottom rail
openings and if necessary clean or vacuum the dust
from the condenser. See Section Cleaning and
Maintenance.
If you want to open the door that has just or recently
been closed, you may find it hard to open. The reason
why this happens is, that when you open the door,
warm air gets into the appliance and when it is
cooling, the underpressure seals the door. After few
minutes (5-10), the door can easily be opened.
Cooling in refrigerating-freezing appliances is enabled
by the cooling system with compressor, which
produces noise. How noisy the appliance is depends
on where it is placed, how it is used and how old the
appliance is.
· During the operation of the compressor the noise of
liquid is heard and when the compressor is not

operating, the refrigerant flow is heard. This is a
normal condition and it has no influence whatsoever
on the lifetime of the appliance.
· After starting the appliance, the operation of the
compressor and the refrigerant flow may be louder,
which does not mean that something is wrong with
the appliance and it has no influence on the lifetime
of the appliance. Gradually the noise is reduced.
