MAINTENANCE AND SERVICING
Cleaning Air Conditioning Evaporator Core
WARNING
To avoid cuts from evaporator fins, do NOT use bare
hands to brush away clogs.
1. Use a vacuum or compressed air to remove dirt from
inside the unit.
2. Blow compressed air through the evaporator fins from
the blower side (A) first as shown. Direct the air straight
into the evaporator to prevent fin damage. A nozzle
extension would make this procedure easier.
3. Repeat the previous step from the side opposite the
blowers (B).
4. If dirt is still present, soak evaporator in water to loosen
dirt and then blow out with compressed air.
