General Refrigerant Precautions
WARNING:
+Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.
+Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or
air conditioning system.
+Do not store or heat refrigerant containers above 52ÉC.
+Do not heat a refrigerant container with an open ¯ame; if container warming is required, place the
bottom of the container in a warm pail of water.
+Do not intentionally drop, puncture, or incinerate refrigerant containers.
+Keep refrigerant away from open ¯ames: poisonous gas will be produced if refrigerant burns.
+Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.
+Do not introduce compressed air to any refrigerant container or refrigerant component.
Precautions for Refrigerant Connection
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
+Expansion valve to cooling unit
+A part of high-pressure line
FEATURES OF NEW TYPE REFRIGERANT CONNECTION
+The O-ring has been relocated. It has also been provided with a groove for proper installation. This elimi-
nates the chance of the O-ring being caught in, or damaged by, the mating part. The sealing direction of
the O-ring is now set vertically in relation to the contacting surface of the mating part to improve sealing
characteristics.
+The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby
facilitating piping connections.
CAUTION:
The new and former refrigerant connections use different O-ring con®gurations. Do not confuse
O-rings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will leak at, or
around, the connection.
