List of periodic maintenance works:
-
check the correct placement and installation of the display case;
-
clean the assembly units from contamination, clean the evaporating unit (if necessary);
-
check that all parts and assemblies are properly secure, tighten all fasteners;
-
check the tightness of brazed hydraulic connectors;
-
check the electrical connections, tighten the screw contacts;
-
check the supply voltage, grounding availability and condition, the integrity of wire and power cable
insulation;
-
checking the interior chilling;
-
check the cyclic operation of the refrigeration system, the condenser fan rotation, the absence of a frost
deposit on the evaporator fins;
-

Warning: Do not turn over the display cases. Handle in vertical position only.
7 Environmental protection
The display cases should meet the environmental requirements established by the current legislation for this
type of equipment. The design of display cases should prevent environmental pollution under normal operating,
starting-up and shutting-down conditions. Prevent emissions of hazardous substances into the air, discharges to
water, and soil contamination and other environmental impacts, except for accidental release of refrigerant,
during display case commissioning, operation and disposal. The environmental safety of display cases during
commissioning and operation shall be ensured by the following:
-
refrigeration system integrity control;
-
working area atmosphere control;
-
measures to prevent environmental pollution by production waste (oiled rags, waste oil).
Operating personnel is responsible for the environmental safety of display cases during commissioning,
operation and disposal.
