INSPECTION
1) Check evaporator fins for blockage. If found clogged, use com-
pressed air to clean the fins.
CAUTION:
Do not use water for cleaning of evaporator.
Be careful not to damage evaporator fins. If evaporator
fin is bent, straighten it by using a screwdriver or pair of
pliers. If any leakage is found from fitting or tube, repair
or replace evaporator.
2) Check inlet and outlet fittings for crack or scratch. Repair them
as required.
REASSEMBLY and INSTALLATION
