Precautions on Servicing A/C System
WARNING:
Should refrigerant HFC-134a (R-134a) strike your eye(s), consult a doctor immediately.
•
Do not use your hand to rub affected eye(s). Instead, use quantities of fresh cold water to splash it over affected area to thus gradually raise its temperature above the freezing point.
• Obtain proper treatment as soon as possible from a doctor or eye specialist. Should liquid refrigerant HFC-134a (R-134a) get on your skin, such affected part should be treated in the same manner as when skin is frostbitten or frozen.

Handling Refrigerant HFC-134a (R-134a)
•
Always wear goggles to protect your eyes.
• Avoid you direct contact to liquid refrigerant.
• Do not heat refrigerant container higher than 40 °C (104 °F).
• Do not discharge refrigerant into atmosphere.
• Do not allow liquid refrigerant to touch bright metals. Refrigerant combined with moisture is corrosive and will tarnish surfaces of bright metals including chrome.

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 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.
Flared Nut used for 12 mm pipe : 23 N·m ( 2.3 kg-m, 17.0 lb-ft)
Flared Nut used for 14.5 mm pipe : 33 N·m ( 3.3 kg-m, 24.0 lb-ft)
•
Route drain hose so that drained water does not make any contact to vehicle components.
• Before evacuating and charging refrigerant, replenish specified amount of compressor oil to compressor suction side by referring to “Replenishing Compressor Oil” in Operation Procedure for Refrigerant Charging .
