d) REPLENISHING COMPRESSOR OIL
(a) While re-installing the Original Compressor
1. Drain and measure the refrigerant oil contained in
the compressor.
2. Charge oil through the discharge port of the com-
pressor with the same amount of new refrigerant
oil.
NOTE
If the amount of oil in the original compressor was
not checked, then approximately 70±10 ml. of new
oil should be added to the compressor being in-
stalled. (This is assuming the compressor being
installed has first been drained).
(b) While installing a New Compressor
A new compressor (1) comes with a certain amount
of oil (A) sealed in it. When replacing the old com-
pressor (2) with a new one; an amount of oil (C) as
calculated below should be drained from the new
compressor.
“C” = “A” -“B”
“C” = Amount of oil to be drained
“A” = Amount of oil sealed in a new compressor (1)
“B” = Amount of oil remaining in old compressor (2)
NOTE
As it is necessary to replenish oil by approximately
the same amount which is remaining in old compres-
sor, draining of additional oil from the New
Compressor becomes necessary.
Following table illustrates the amount of oil to
be replenished for respective HVAC/AC com-
ponents

NOTE
When only charging refrigerant without replacing any
component, replenish the same amount of measured
oil when recovering refrigerant, if not measured, re-
plenish 30cc oil.
CAUTION:
Specify SP10 oil for compressor Top-Up.
