Air Conditioning Compressor Oil Balancing
Draining Procedure
|
Note: Drain and
measure as much of the refrigerant oil as possible from the removed
compressor.
|
1. |
Remove the compressor
crankcase oil drain plug and drain the crankcase (1) into a clean,
graduated container. |
2. |
Drain the oil from both the
suction and discharge ports of the removed compressor into the same
container. Rotate the compressor shaft to assist in draining the
compressor. |
3. |
Measure and record the amount
of oil drained from the removed compressor. This measurement will
be used during installation of the replacement compressor.
|
5. |
Properly discard the used
refrigerant oil. |
Balancing Procedure
|
Note: The refrigerant
oil in the A/C system must be balanced during compressor
replacement.
|
1. |
The replacement compressor is
shipped with the total system capacity of refrigerant oil.
|
2. |
Before installing the
compressor (1), the refrigerant oil will have to be partially
drained: |
|
• |
Refer to the amount of
refrigerant oil recorded during the compressor removal.
|
|
• |
The difference between the
total system capacity and the recorded amount is the calculated
amount to be drained from the replacement compressor. |
3. |
Drain the calculated amount of
refrigerant oil from the replacement compressor. |
