3. TRANSPORTATION, INSTALLATION AND COMMISSIONING
3.1. Transportation method
e unit requires careful protection against damage and accidental overturning during transportation. Glass elements and painted
surfaces are especially vulnerable. e equipment must be in an upright (working) position both when transporting and when moving. Aer
installing the equipment in a specic location, the network connection must be made aer a minimum of 6 hours.
3.2. Storage method
e cabinet must always be stored in an upright position. Do not store the equipment exposed to direct sunlight or other weather
conditions (rain, snow, etc.).
3.3. Operating site requirements
e equipment should be installed in a dry, well ventilated place that allows good air circulation (distance between the wall and the unit
should be at least 10 cm), away from heat sources and devices that generate air ow (including fans, air conditioners).
Do not install the equipment in locations exposed to direct sunlight, rain, snow, etc.
Make sure that the cross-section of the power lines is suitable for the current power consumption.
3.4. Equipment installation and preparation for operation
Place the cabinet on the work surface and level it horizontally with the adjustable supports (Figure 1). Precise horizontal positioning
of the equipment aects the reduction of unit noise and guarantees condensate drainage.
Set the brackets to the desired height and install the shelves on them.
It is necessary to install the cabinet not closer than 2m from the heating devices in
order to ensure its normal operation. Do not use the cabinet when it is exposed to direct
sunlight, air ows from air conditioners, fans and heaters
Wash the interior and exterior surfaces of the cabinet with non-corrosive and non-
abrasiv
3.5. Connection and commissioning
Requirements for operation:
а) Aer transportation or storage at low temperatures, keep the cabinet at a temperature
not lower than the operating temperature for 24 hours before start-up. Starting equipment
that has not been warmed up can cause the compressor to jam and result in product failure
b) products intended for display in refrigeration equipment should be loaded on the shelves evenly, cooled to the temperature of the
working volume;
c) place products in such a way that they do not interfere with the air circulation between the evaporator and the internal volume of the
equipment;
Height adjustment

DO NOT:
• cover and block the ventilation openings of the equipment;
• install the equipment near heat sources (heaters, radiators) and under direct sunlight;
• install the equipment in draughts.
If the requirements are not met, air circulation is impaired and product performance deteriorates, which can lead to food spoilage.
e product compressor works cyclically, switching o when the set temperature is reached and switching on when the temperature
rises by 2-3°C. At the same time, the temperature at certain points of the cooled volume may
temporarily increase and dier from the controller reading, which is not a defect.
e compressor stops periodically to defrost the evaporator during the cabinet
operation. When defrosting, the temperature in the cooled volume may increase, which is
not a defect.
ese are the main indicators of the normal operation of a refrigerated cabinet:
- the temperature of the internal volume corresponds to the set temperature;
- e refrigeration machine works cyclically.
e equipment must be connected to the 230 V/50Hz mains supply, for this purpose a
demountable plug is provided, which makes it possible to connect both through a grounded
socket and directly to the mains. Make sure that the circuit breaker (Figure 2) is turned o
before doing this.
• When plugged in, the control panel lights should turn on.
• Check the power supply voltage before connecting the equipment to the mains.
ATTENTION!
- e unit's compressor is adapted for operation with a supply voltage not lower
than 210 V and not higher than 240 V. Operating the unit outside of these power
settings can cause irreparable damage to the compressor.
- If the circuit breaker trips when connecting the cabinet, contact the service
center.
• Necessary safety precautions:
1. e equipment must be connected by a qualied electrician.
2. In case of a malfunction such as a damaged power cord, sparking, etc., the equipment must be immediately disconnected from the mains.
3. Washing and cleaning can only be done aer disconnecting the power supply or turning o the circuit breaker.

4. If the power cord is damaged, it must be replaced by the manufacturer or the manufacturer's service technician or a qualied electrician
in order to prevent any possible damage to life or health.
5. DO NOT connect the cabinet through extension cords that do not have a grounding wire, or if the cross-sectional area of the
extension cord is less than 1.5 sq. mm.
3.6. Operation of energy-saving night blinds
(curtains)
For maintaining the temperature inside the
refrigerated multideck at night, the use of night
blinds is recommended.In the open state, the
hook of the night curtain enters the groove at
the top of the multideck (left image). In order
to close the window you need to pull the hook
down and fix it in a special hole (right-image).
