SERVICE INFORMATION

If A/C compressor has seized during operation, the refrigerant system must be flushed to remove contaminants before installing new compressor.

WARNING: Always wear safety goggles when charging or discharging system. Be sure work area is well ventilated. Refrigerant-12 is heavier than air and can accumulate in areas of poor air circulation. Avoid inhaling fumes when using flame type leak detector. Refrigerant-12 becomes poisonous gas after coming into contact with open flame.

CAUTION: Always discharge refrigerant from air conditioner system before loosening connections, hoses, etc.

NOTE: Refrigerant R-12 may be used for flushing if refrigerant R-11 is not available.

- Replace expansion valve if contaminated.

- Replace receiver/drier.

- Install compressor.
