Air Conditioning System: 7B-2
• Never use heat for bending pipes. When bending a pipe, try to make its bending angle as smooth 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 O-ring.
• When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
• Route drain hose so that drained water does not make any contact to vehicle components.
• If pipes or hoses are replaced, replenish specified amount of compressor oil to compressor suction side referring to
“Replenishing Compressor Oil” in “Operation Procedure for Refrigerant Charge: ”.
Refrigerant Recovery
When discharging refrigerant out of A/C system, always recover it by using refrigerant recovery and recycling
equipment because discharging refrigerant HFC-134a (R-134a) into atmosphere would cause adverse effect to
environments.
Refrigerant Charge
After performing compressor oil replenishment and evacuation, charge a proper amount of refrigerant to A/C system
referring to “Charge” in “Operation Procedure for Refrigerant Charge: ”.
