1B-30 AIR CONDITIONING (OPTIONAL)
WARNING:
Should refrigerant HFC-134a (R-134a) strike your eye(s), consult a doctor immediately.
D 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.
D 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.
CAUTION:
None of refrigerant, compressor oil and component parts is interchangeable between two types of A/C:
one using CFC-12 (R-12) and the other using HFC-134a (R-134a).
(For identification between these two types, refer to page 1B-2).
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A/C installed in the vehicle being serviced.
Use of incorrect one will result in leakage of refrigerant, damage in parts or other faulty condition.

PRECAUTION

When servicing air conditioning system, the following rules must be observed.
PIPING
D When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to seats of coupling nuts
and O-ring.
D Never use heat for bending pipes. When bending a pipe, try to make its bending radius as slight as possible.
D 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.
D When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
