WARNING

Compressed air used for cleaning purposes should not exceed 30 psi (2.1 kg/cm2)

1. Using compressed air, blow accumulated dust

and dirt out of air passages in the evaporator

coil (1). Blow from front to back, in opposite

direction from the operational airflow.

2. Inspect coil (1) for damage and check mounting

hardware for tightness and security. Straighten

any bent fins.

Heating elements

1. Wipe any remaining dust or dirt from the

heating elements (2), heater thermostat, and all

other components or surface in the area.

NOTE

Use a clean, dry cloth (or a slightly moistened cloth) when wiping the unit. NEVER use

an oily or greasy cloth; residue left on any surface will attract and accumulate much

more dust and dirt than dry surfaces.

2. Inspect the heating elements (2) and thermostat

for obvious damage and all mounting hardware

for tightness and security.

3. Inspect wiring harness for damage or chafing

and all electrical connections for tightness.

4. Install mist eliminator, conditioned air supply

louver, and the top-front panel.
