Precautions on Servicing Refrigerant Line
-
When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to seats of coupling nuts and O-ring.
-
Never use heat for bending pipes. When bending a pipe, try to make its bending radius as slight as possible.

Keep internal parts of air conditioning free from moisture and dirt. When disconnecting any line from system, install a blind plug or cap to the
fitting immediately.
-
When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
