Periodic Maintenance


PERIODIC MAINTENANCE
Routine servicing apart from visual checks is not necessary. The visual inspections are as follows:

Condenser--With a garden hose or air line, clean the fins of the condenser to remove flies, leaves, etc. Check the hose connection for signs of oil leakage.

Compressor--Check hose connections for signs of oil leakage. Check flexible hoses for swelling. Examine the compressor belt for tightness and condition. Checking the compressor oil level and topping-up is only necessary after charging the system or in the event of a malfunction of the system.

Receiver/Drier--Examine the sight glass for bubbles with the system operating. Check connections for leakage.

Evaporator--Examine the refrigeration connections at the unit. If the system should develop a fault, or if erratic operation is noticed, refer to the fault diagnosis chart.
