A/C Service Tips and Precautions

CAUTION:
1. Always disconnect the negative cable from the battery whenever replacing air conditioner 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 the lines are reconnected.
3. Before connecting any hose or line, apply a few drops of refrigerant oil to the seat of the 0-ring or flare nut.
4. When tightening or loosening a fitting, use a second wrench to support the matching fitting.
5. When discharging the system, use a Refrigerant Recovery/Recycling System; don't release refrigerant into the atmosphere.
6. Add refrigerant oil after replacing the following parts:
- Condenser 30 cc (1 fl-oz)
- Evaporator 60 cc (2 fl-oz)
- Line or hose 10cc (1/3 fl-oz)
- Receiver 10 cc (1/3 fl-oz)
- Compressor, calculate as follows:
When a new compressor is installed, drain 30 cc (1 fl-oz) of refrigerant oil from the suction fitting on the compressor. If you are also replacing any of the above parts, pro-rate the amount you drain by the amount you should add for the other part(s).
