Hose/Line HVAC: Service Precautions
Precautions for Refrigerant Connection
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
-
Expansion valve to evaporator
-
Refrigerant pressure sensor to condenser.
FEATURES OF NEW TYPE REFRIGERANT CONNECTION
-
The O-ring has been relocated. It has also been provided with a groove for proper installation. This eliminates 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.
