Technician Safety Information

A/C System, Safety Measures

The subassemblies and lines of the air conditioner are filled with difluorodichloro methane (CF2Cl2) as a refrigerant; This refrigerant is known under the commercial name of Frigen R 12 or Freon R 12

Replacement A/C compressors supplied by the Parts Department are filled with 135 cc (4.6 oz) of A/C refrigerant oil.

A/C system refrigerant capacity:
1200 g ± 50 g (42.3 oz. ± 1.7 oz.)

A/C system refrigerant oil capacity:
135 cc (4.6 oz.)

WARNING:
- A/C system is filled with R12 refrigerant gas which is under pressure
- always be careful that refrigerant does not come in contact with your skin
- always wear eye protection when working around the system
- if liquid refrigerant has come in contact with your skin or eyes:
- do not rub skin or eyes
- immediately flush with cool water for 15 minutes
- rush to a doctor or hospital
- do not attempt to treat yourself
- keep refrigerant containers stored below 50°C (122°F) and never drop from high places
- keep refrigerant away from open flames because poisonous gas will be produced if it burns. Do not smoke when refrigerant gases are present for the same reason
- electric welding near refrigerant hoses causes refrigerant to decompose from ultraviolet light. Discharge system before electric welding
- do not expose any component of the A/C system to high temperatures (i.e., open flames). Excessive heat will cause a pressure increase which could burst the system
- do not steam clean condensers or evaporators. Use only cold water or compressed air
- automotive refrigerant containing CFC's is hazardous to the earth's atmosphere. To protect our environment, use an Underwriter's Laboratory (UL) approved refrigerant recovery/recycling unit such as Kent Moore ACR3, or equivalent, whenever discharging an A/C system
