ELECTRICAL SYSTEM
For a new compressor to be used in this type of system,
subtract the delivered oil amount from the desired total
oil charge to determine how much oil should be added to the com-
pressor and system.
Remove the oil filler plug and charge the compressor with the
amount of additional oil determined in previous picture. Use only
new oil of the correct type as shown on the compressor label. If cal-
culated amount is greater than 300cc (10oz) oil can be added
to other system components.
Repair
If a repair is performed on an R134a compressor or system, evacu-
ate the system for at least 30 minutes before recharging to ensure the
removal of moisture which may have been absorbed by the PAG oil in
the compressor and system.
Oil replacement amount during service:
When replacing a system component the goal is to restore to the
original factory amount. This can be found on compressor label. Use
the chart below as a guide for restoring oil quantities when replacing
system components.
