• 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 connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to seats of coupling nuts and O-ring.
• When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
• Tighten flared nuts by the following specified torque.

  Tightening torque 

  8 mm pipe: 13 N.m (1.3 kg-m, 9.5 lb-ft)

  12 mm pipe: 23 N.m (2.3 kg-m, 16.6 lb-ft)

  14.5 mm pipe: 33 N.m (3.3 kg-m, 23.8 lb-ft)
