The list of work performed during maintenance of refrigeration equipment includes:
- external inspection of the equipment to detect mechanical damage to the housing, internal volume and to check the compliance of operation with safety rules;
- check of completeness, availability of protective shielding, reliability of fastenings and grounding;
- inspection and testing of automation devices, electrical equipment, lights, fittings and tightening connections;
- checking air tightness of the unit, compressor, electric motor, serviceability of the refrigeration equipment and its components.
Besides this, the oil level in the compressor crankcase and refrigerant, condensing pressure are necessarily controlled. The temperature mode in the cooled volume and the automatic operation mode are checked. If any malfunctions are detected during servicing of the refrigeration equipment, additional measures are taken.
