A/C Service Precautions

REFRIGERANT COMPATIBILITY
The air conditioner system uses HFC-134a (R-134a) refrigerant and polyalkyleneglycol (PAG) refrigerant oil (Nippondenso: ND-OIL 8, P/N 38899 - PR7 - A01 or Hadsys: Dn. S10X, P/N 38899 - POA - A01), which are not compatible with CFC-12 (R12) 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.

SERVICE TIPS AND PRECAUTIONS
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 (Nippondenso: ND-OIL 8, P/N 38899 - PR7 - A01 or Hadsys: Dn. S10X, P/N 38899 - POA-A01) to the 0-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 (Nippondenso: ND-OIL 8, P/N 38899 - PR7 - A01 or Hadsys: Dn. S10X, P/N 38899 - POA - A01) after replacing the following parts: (see specifications for quantity)
- Condenser
- Evaporator
- Line or hose
- Receiver/Dryer
- Leakage repair
- Compressor

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 car; it may damage the paint; if the refrigerant oil contacts the paint, wash it off immediately.
