A/C Service Tips and Precautions
COMPONENT REPLACEMENT1. 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 (Sanden: SP-10, P/N 38899 - P13 - A01) to the 0-ring.
4. When tightening or loosening a fitting, use a second wrench to support the matching fitting.
5. When recovering the system, use a R-134a refrigerant Recovery/Recycling/Charging System; don't release refrigerant into the atmosphere.
6. Add refrigerant oil (Sanden: SP-10, P/N 38899 - P13 - A01) after replacing the following parts:
- Condenser 10 ml (1/3 fl.oz, 0.4 Imp.oz)
- Evaporator 30 ml (1 fl.oz, 1.2 Imp.oz)
- Line or hose 10 ml (1/3 fl.oz, 0.4 Imp.oz)
- Receiver/Dryer 10 ml (1/3 fl.oz, 0.4 Imp.oz)
- Leakage repair 25 ml (5/6 fl.oz, 0.9 Imp.oz)
- Compressor replacement: Calculate as follows:
For compressor replacement, subtract the volume of oil drained from the removed compressor from 130 ml (4 1/3 fl.oz, 4.6 Imp.oz), and drain the calculated volume of oil from the new compressor: 130 m' (4 1/3 fl.oz, 4.6 Imp.oz) - Volume of removed compressor = Volume to drain from new 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.
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.
