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)
Route drain hose so that drained water does not make any contact to vehicle components.
