Install the refrigerated display cabinets on an even horizontal surface, if necessary, use adjustable legs to level up
the product. The refrigerated display cabinets should not tilt, incomplete alignment can result in deterioration of the prod-
uct work.
If the refrigerated display cabinets has wheels, they must be fixed after the product installation.
DO NOT install the refrigerated display cabinets in the following places (Fig. 3):
• in close proximity to heat sources (e.g. heating batteries, equipment for food heating or cooking);
• near the doors or in a draft caused by opening of the doors or windows;
• in areas where strong air movement is possible (e.g. outlets of climatic, ventilation and heating systems);
• exposed to direct sunlight.
Air movement at a speed of over 0,2 m/sec in the area of the refrigerated display cabinets installation deteriorates
its operating characteristics.
Install the refrigerated display cabinets in such a way as to ensure free air circulation in the unit compart-
ment. Ensure a free zone of no less than 15 cm from the back wall of the refrigerated display cabinets to discharge warm
air from the condenser.

operating rules at fuels and lubricants facilities. According to the requirements of UL 471, the refrigerated
display cabinets charged with a highly flammable refrigerant must be arranged at the level of no less than 18
inches (450 mm)0 above ground level at fuels and lubricants facilities.
According to the requirements of EN 378-1-2014, for refrigerated display cabinets charged with a flammable
refrigerant (e.g. R290) a minimum volume of premises is specified based on the lower flammability limit. For
example, the minimum volume of the room where the refrigerated display cabinets charged with R290 can be
arranged is 12,5 m
charged with a flammable refrigerant are located in one room, their charge values are summed up and the
volume of the room is selected accoding to their total charge (charge values are indicated on the nameplates).
In case of non-compliance with the refrigerated display cabinets installation rules, its operating characteristics may
differ from those stated.
