UNPLUGGED.
It is mandatory that the Customer performs the following operations during the Preventive
Maintenance of an ICM once or twice a year, using a vacuum cleaner:
Cleaning of the condenser
Cleaning of the dust filters (if applicable).
If the ICM is placed in an environment where dust is accumulated on the condenser, then the
condenser has to be cleaned more often.
Additionally, it is recommended that the following operations are carried out during preventive
maintenance:
1. Mechanical system:
Check that the equipment is correctly positioned and leveled.
Check that the front and back grid are fixed in place.
Check the self-closing system of the door.
Check that the fan support and fan grid are fixed in place.
Check the draining system and unclog if necessary.
2. Electrical system:
Check the power cable (replace if needed).
Check the illumination system.
Check the electrical connections.
Check that the electrical box cover of the thermostat or the electronic controller is properly
installed.
Check that components that might have been replaced during servicing are original.
3. Refrigeration system:
Check that the compressor is functioning properly.
Check the starting relay, the overload and the capacitor. The Supplier recommends that the
compressor's starting relays and overloads be replaced every 3-4 years.
Check the fan motor condenser and fan motor evaporator.
Check that the thermostat or the electronic controller and its components are functioning properly.
Check the cooling performance of the ICM.
Check the cooling circuit using the appropriate leak detector in case there is any concern or sign
