Sephia Sedan L4-1.6L SOHC 16V (1993)
Refrigerant: Technician Safety Information
A/C Service Tips
The air conditioner 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 conditioner 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 conditioner system.
CAUTION: Exposure to air conditioner refrigerant and lubricant vapor or mist can irritate eyes, nose and throat. Avoid breathing the air
conditioner refrigerant and lubricant vapor or mist.
If accidental system discharge occurs, ventilate work area before resuming service.
R-134a service equipment or vehicle air conditioner systems should not be pressure tested or leak tested with compressed air.
WARNING: Some mixtures of air and R-134a have been shown to be combustible at elevated pressures and can result in fire or explosion
causing injury or property damage. Never use compressed air to pressure test R-134a service equipment or vehicle air conditioner systems.
Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.
1. Always disconnect the negative cable from the battery whenever replacing air conditioning parts.
2. Keep moisture and dust 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.
3. Before connecting any hose or line, apply a few drops of refrigerant oil to the O-ring.
4. When tightening or loosening a fitting, use a second wrench to support the matching fitting.
5. When discharging the system, use a R-134a refrigerant Recovery/Recycling/Charging System; don't release refrigerant into the atmosphere.
6. Add refrigerant oil after replacing the following parts:
NOTE:
*
To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refrigerant oils.
*
Immediately after using the oil, replace the cap on the container, and seal it to avoid moisture absorption.
*
Do not spill the refrigerant oil on the vehicle it may damage the paint; if the refrigerant oil contacts the paint, wash it off immediately.

WARNING:
*
SHOULD HFC-134A CONTACT YOUR EYE(S), CONSULT A DOCTOR IMMEDIATELY.
*
DO NOT RUB THE AFFECTED EYE(S). INSTEAD, SPLASH QUANTITIES OF FRESH COLD WATER OVER THE AFFECTED
AREA TO GRADUALLY RAISE THE TEMPERATURE OF THE REFRIGERANT ABOVE THE FREEZING POINT.
*
OBTAIN PROPER MEDICAL TREATMENT AS SOON AS POSSIBLE. SHOULD THE HFC-134A TOUCH THE SKIN, THE
INJURY MUST BE TREATED THE SAME AS SKIN WHICH HAS BEEN FROSTBITTEN OR FROZEN.
IMPORTANT:
-
Always wear safety goggle and protective gloves when working on refrigerant systems.
-
Beware of the danger of carbon monoxide fumes caused by running the engine.
-
Beware of discharged refrigerant in enclosed or improperly ventilated garages.
-
Always disconnect the negative battery cable and discharge and recover the refrigerant whenever repairing the air conditioning system
CAUTION: Avoid breathing A/C Refrigerant-134a and lubricant vapor and mist. Exposure may irritate eyes, nose, and throat. To remove R-134a from
the A/C system, use service equipment certified to meet the requirements of SAE J2210 (R-134a recycling equipment). If accidental system discharge
occurs, ventilate the work area before resuming service. Additional health and safety information may be obtained from the refrigerant and lubricant
manufacturers.
IMPORTANT:
-
Do not mix R-12 refrigerant and R-134a refrigerant, even in the smallest amounts. R12 and R-134a are incompatible with each other. If the
refrigerants are mixed, compressor failure is likely to occur.
-
Use only the specified lubricant for the R-134a A/C system and R-134a components. If you use lubricants other than those specified, compressor
failure is likely to occur. Coat all the fittings and the O-ring seals with clean refrigerant oil in order to provide a leak-proof seal and in order to aid
in assembly and disassembly.
-
Do not store or heat the refrigerant containers above 52 °C (125 °F).
-
Do not heat a refrigerant container with an open flame. If the container must be warmed, place the bottom of the container in a pail of warm water.
-
Do NOT intentionally do the following to the refrigerant containers:
-
Drop
-
Puncture
