filter to cab wall, and pull off the cover and filter
assembly.
b. Separate the filter (E) from the cover (F).

7.7.6.3 A/C Condenser
The air conditioning condenser should be cleaned
daily with compressed air. More frequent cleaning
may be necessary in severe conditions.
Cleaning the condenser can be done at the same
time as the radiator, oil cooler, and charge air
cooler. Refer to Section 7.10.2 Cooling Box
Maintenance.

The evaporator is located inside the heating air
conditioning unit under the cab.
To clean the evaporator, proceed as follows:
