Precautions for Refrigerant Connection
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
lExpansion valve to cooling unit
FEATURES OF NEW TYPE REFRIGERANT CONNECTION
lThe 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 char-
acteristics.
lThe 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 configurations. 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.
