Refrigerant Line
• 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 moistu re 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.
• When handling recovery and recycling equipment, be sure to follow the instruction manual for the equipment.
• Check local governmental regulations regarding working with refrigerator systems and its tooling.
• 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 compre ssor 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-1 34a) into atmosphere would cause adverse effect to
environments.
NOTE
When handling recovery and recycling equipment, be sure to follow the instruction manual for the
equipment.
Refrigerant Charge
After performing compressor oil replenishment and evacuat ion, charge a proper amount of refrigerant to A/C system
referring to “Charge” in “Operation Procedure for Refrigerant Charge”.
