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.

CAUTION

Refrigerant oil must be added to air conditioner system before charging with refrigerant or air

conditioner compressor will be damaged. Add same amount of new refrigerant oil in air conditioner

compressor as was noted during recovery or evacuation, except if charging for the first time.

Maximum amount of refrigerant oil required for air conditioner system is 13 oz (369 g).

RECOVERY and EVACUATION/RECYCLING procedures must be performed before system is

charged or damage to system may result, except if charging for the first time.

Air conditioner system must be in a 10 to 15 in. Hg vacuum status before charging.

Use care to prevent overcharging or damage to compressor may result.
