Balancing Procedure

  1. NOTE: The refrigerant oil in the A/C system must be balanced during compressor replacement.
    NOTE: Check the oil volume in the replacement compressor.

    The replacement compressor is shipped partially filled with refrigerant oil. The amount of oil has to be balanced according to below.

  2. Before installing the compressor, the refrigerant oil will have to be drained:

    Drain the replacement compressor completely from oil as described above, Draining procedure - item 1 and 2, into a clean, graded container.

  3. Add the same amount of oil into the new compressor as was drain and recorded from the replaced compressor + 20 ml. If no oil (or very little amount = equal or less than 10 ml) was drained from the replaced compressor, fill 50 ml of oil in the new compressor.
