Part 2:
Technical details and maintenance
2.1. Operating temperature range
The chest freezer can be used both indoors and outdoors, in street
conditions.
The manufacturer guarantees normal operation of the chest freezer
under conditions of temperature exposure according to climatic class.
To ensure the temperature range inside the freezing chamber, the chest
freezer is equipped with a thermostat. The thermostat has the following
factory settings: minimum temperature in the chest freezer compartment
at which the compressor is switched off -25°C, maximum temperature
in the chest freezer compartment at which the compressor is switched
on -18°C.
2.2. Unpacking
Unpack the chest freezer carefully - do not turn it over, do not
put it on its side, and then visually check for damage. Remove the
device from a shipping pallet.

6
2.3. Placement and Installation
To ensure normal operation, the device must be installed
away from heaters and in a place protected from direct sunlight.
Do not allow precipitation in the form of rain and snow to
enter the device.
•
The device is equipped with rotary rollers. Make sure the floor
surface is not inclined and facilitates easy movement and
installation of your device.
•
Install the brake rollers in front of the chest.
Placement and installation of the chest freezer on site
should provide a free area of at least 20 cm from the chest
ventilation grilles to the fence or dimensional object to ensure free
air circulation.
Insufficient air circulation around the chest freezer leads to
reduced productivity and increases the likelihood of breakdowns
and equipment failure.
•
Check the power cord and plug for mechanical damage by
visual inspection.

7
If mechanical damage to the power cord or plug is
detected, DO NOT connect the device to the power supply. The
power cord and plug must be replaced
• Plug the mains plug of the chest freezer into a grounded power
socket.
DO NOT operate the chest freezer without a grounding
contact in the mains socket. It is not allowed to connect several
chest freezers to one mains socket of power supply via an
"extension" with branch sockets.
2.4. Commissioning
Turn on the power of the chest freezer, to do this connect the
chest power cord to the network. A sign of the switching on of the
freezer chest in the cooling mode is the switching on of the
compressor and the condenser fan.
Allow the device to run for 1.5 hours without putting food into it
and the glass doors must be closed tightly.
It is advisable to keep the products packaged in the device.
In the event of a sudden power failure, the chest freezer must be
switched off. Pause for 5 minutes to switch on again.

8
Do not load the device with products above the loading
limit (index red line inside the camera).
Remember, the chest freezer is designed for storing frozen
food.
Do not store explosive materials or aerosol containers with
combustible displacement gases such as propane, butane,
pentane, etc. in the device. Escaping gases may ignite from
electrical parts. Such aerosol packs can be easily recognized by
the content printed on them or by the flame symbol.
Before starting up the equipment, read carefully the rules
of preparation for operation and the rules of operation of a chest
freezer as specified in this manual.
2.5. Temperature parameters
The setting parameters of the thermostat can only be
changed if necessary by the employee of the service department
servicing this equipment. Unauthorized changes to the thermostat
settings will result in an expiry of the warranty period.
2.6. Tips and remarks
Sudden power outage
1. Covering the outer glass surfaces with a cover helps to keep the
temperature as low as possible for a longer period of time.

9
2. If there is a prolonged lack of power, place dry ice in the
freezer compartment.
3. If possible, reduce the number of door openings/closings.
4. If possible, avoid placing new portions of food in the chest
freezer as this leads to an increase in the temperature inside the
compartment.
If the device is not used for a long time.
1. Disconnect the device from the mains (unplug the power cord from
the socket) and remove everything from the freezer compartment.
2. Clean the interior and remove all water. Leave the door open
until the freezer compartment is completely dry to avoid mildew and
odor.
2.7. Safety rules
Personnel involved in the installation and commissioning of the
chest freezer must be familiar with this manual and work in
accordance with its recommendations and requirements.
Heating the chest crown is a constructive solution to
prevent the glasses from fogging it is not a malfunction!
Follow the precautions and safety precautions in section 2.8
during operation.

10
2.8. Safety requirements
The device complies with Class I of electrical safety.
Before connecting the chest freezer to the electric power network,
make sure that
– the network voltage corresponds to the value given on the
device nameplate (+10%, –15%);
– the power cord and plug are not damaged.
The chest freezer must be connected to a grounded power supply
socket. Do not connect the freezer to a power supply with a faulty
overcurrent protection. Check this before starting the installation process.
Do not use any adapters, additional sockets or extension cords that
do not match the current load of the device.
If there are signs of faulty wiring (smell, smoke), disconnect the power
supply to the device and call a service technician to remedy the fault.
It is forbidden to operate the
chest freezer:
•
if the nominal supply voltage indicated on the nameplate deviates
by more than + 10% - 15%.
•
in case of high level of humidity and dustiness of the environment
(relative humidity above 75%, when ceiling, walls, floor and other
objects in the room are covered with moisture);

11
• under conditions of chemically active environment, which leads to
destruction of electrical insulation and oxidation of conductive
contact connections
• with a conductive floor surface.
The chest freezer must be disconnected from the
power supply in the following cases:
• when cleaning the chest freezer inside and outside;
• when moving the device;
• when performing operations related to servicing the chest freezer
and troubleshooting;
Intended use
Do not store bottles or containers in the chest freezer. The contents
may freeze and containers may explode and cause injury. The device
is designed to store ice cream and frozen food. Storage of other
products may have a significant effect on products already stored in the
appliance.
The manufacturer is not responsible for possible injury to
the user or damage to the equipment if the requirements in this
section of the manual are not complied with.

12
R600a - isobutane or R290 - propane is used as the
refrigerant of the refrigerated cabinet (the brand and dose of
the refrigerant are indicated on the nameplate of the
refrigerator) - natural gas, which is combustible, then the
refrigerating cabinet is is labeled with a special warning label
located behind the product in the area of the refrigeration
unit, with the obligatory indication of the gas brand. As a
result of accidental damage to the refrigerant circuit, avoid
any kind of naked flame or potential sources of ignition and
thoroughly air the room where the refrigerator is located. The
volume of the room should be 1 m for every 8 g. of refrigerant
R600a or R290 in the product. Never turn on the refrigerator
with signs of damage. If you have doubts about the health of
the product, contact an authorized service center.
ATTENTION! Do not use electrical appliances inside the
device.
ATTENTION! Do not block the cooling vents in the
cabinet or in the built-in design!
ATTENTION! Do not damage the refrigerant circuit.
ATTENTION! Do not use mechanical devices or other
means to accelerate the defrosting process.

13
