Refrigerant: Service Precautions

WARNING:
^ The air conditioning system is charged with a high pressure, potentially toxic refrigerant. Repairs or servicing must only be carried out by an operator familiar with both the vehicle system and the charging and testing equipment.
^ All operations must be carried out in a well-ventilated area away from open flame and heat sources.
^ Always wear safety goggles and gloves when opening refrigerant connections.
^ Wear eye and hand safety protection. Open connections slowly in case liquid or pressure is present. Allow to bleed off slowly.

CAUTION:
^ Overcharging air conditioning system will cause excessive head pressure.
^ An air conditioning portable refrigerant recovery recycling recharging station for use with R134a refrigerant incorporates all the features necessary to recover refrigerant R134a from the air conditioning system, to filter and remove moisture, to evacuate and recharge with the reclaimed refrigerant. The unit can also be used for performance testing and air conditioning system analysis. The operator must adhere to the equipment manufacturers' instructions.
