1. Start engine (TM 9-2320-279-10) and run at idle until normal operating temperature is reached.

2. Shut engine OFF (TM 9-2320-279-10).

WARNING

Use care to prevent refrigerant from touching skin or eyes. Liquid refrigerant, when

exposed to air, quickly evaporates and will freeze skin or eye tissues. Serious

injury or blindness may result if you come in contact with liquid refrigerant.

Refrigerant R-134a air conditioning systems should not be pressure tested or leak

tested with compressed air. Combustible mixtures of air and R-134a may form,

resulting in a fire or explosion, which could cause personnel injury or death.

Wear protective goggles and nonleather gloves when servicing air conditioner

system. Failure to comply may result in injury to personnel.

NOTE

Service valves are located on two AC hoses attached to AC compressor.

3. Remove cap (1) from service valve (2) on hose (3).

4. Remove cap (4) from service valve (5) on hose (6).
