CHARGING
WAR N I N G
Use care to prevent refrigerant from touching your skin or eyes; wear protective goggles and nonleather gloves when
servicing Air Conditioning systems. 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 A/C 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.
CAU T I ON
RECOVERY and EVACUATION/RECYCLING procedures must be performed before system is charged or
damage to system may result.
Use care to prevent overcharging or damage to compressor may result.
N OT E
Obtain enough refrigerant in container to fully charge system.
1.
Position R-134a tank on scale to make sure enough refrigerant is available to fully charge system. Weight of R-134a
should be 48 fluid ounces (1.42 liter).
Refer to Table 1, Ambient Temp/PSI Cross-Reference, for proper system pressure levels at measured temperatures.
