Air Conditioning Evaporator - MacDon M105 Operator's Manual

Air Conditioning Evaporator

The air conditioning evaporator should be checked annually for cleanliness. If the air conditioning system produces
insufficient cooling, a possible cause is clogged evaporator fins. Fins will clog up from the side opposite the
blowers. The evaporator is located inside the heating air conditioning unit under the cab. It is accessed by
removing the cover from the unit.
