A/C SERVICE TIPS & PRECAUTIONS

WARNING:

z

Compressed air mixed with R-134a forms a combustible vapor.

z

The vapor can burn or explode causing serious injury.

z

Never use compressed air to pressure test R-134a service
equipment or vehicle air conditioning systems.

The air conditioning system uses HFC-134a (R-134a) refrigerant and polyalkyleneglycol (PAG) refrigerant oil,
which are not compatible with CFC-12 (R-12) refrigerant and mineral oil. Do not use R-12 refrigerant or
mineral oil in this system, and do not attempt to use R-12 servicing equipment; damage to the air conditioning
system or your servicing equipment will result. Use only service equipment that is U.L.-listed and is certified to
meet the requirements of SAE J2210 to remove R-134a from the air conditioning system.

If accidental system discharge occurs, ventilate work area before resuming service.

R-134a service equipment or vehicle air conditioning systems should not be pressure tested or leak tested with
compressed air.

Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.

z

Always disconnect the negative cable from the battery whenever replacing air conditioning parts.

z

Keep moisture and dirt out of the system. When disconnecting any lines, plug or cap the fittings
immediately; don't remove the caps or plugs until just before you reconnect each line.

z

Before connecting any hose or line, apply a few drops of refrigerant oil to the O-ring.

z

When tightening or loosening a fitting, use a second wrench to support the matching fitting.

z

When discharging the system, use a R-134a refrigerant recovery/recycling/charging station; don't release
refrigerant into the atmosphere.

A/C REFRIGERANT OIL REPLACEMENT

Recommended PAG Oil: KEIHIN SP-10

z

P/N 38897-P13-003: 120 ml (4 fl. oz.)

z

P/N 38899-P13-A01: 40 ml (1 1/3 fl. oz.)

Add the recommended refrigerant oil in the amount listed if you replace any of the following parts:

Condenser: 25 ml (5/6 fl. oz.)

Evaporator: 45 ml (1 1/2 fl. oz.)

Line Or Hose: 10 ml (1/3 fl. oz.)

Receiver/Dryer: 10 ml (1/3 fl. oz.)

Leakage Repair: 25 ml (5/6 fl. oz.)

Compressor For Compressor Replacement: Subtract the volume of oil drained from the removed
compressor from 130 ml (5 1/3 fl. oz.), and drain the calculated volume of oil from the new compressor:

Example: 130 ml (5 1/3 fl. oz.) - Volume of removed compressor = Volume to drain from new
compressor

CAUTION:

z

Air conditioning refrigerant or lubricant vapor can irritate your eyes,
nose, or throat.

z

Be careful when connecting service equipment.

z

Do not breathe refrigerant or vapor.

z

To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other
refrigerant oils.

z

Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture absorption.

z

Do not spill the refrigerant oil on the vehicle; it may damage the paint; if it gets on the paint, wash it off
immediately.

Fig. 6: For Compressor Replacement, Subtract The Volume Of Oil Drained From The Removed
Compressor

NOTE:

Even if no oil is drained from the removed compressor, don't drain
more than 50 ml (1 2/3 fl. oz.) from the new compressor.
