OIL CHARGE
Puron systems use a polyolester (POE) oil. Use only Carrier
approved compressor oil. Table 68 lists indicates the factory oil
charge per compressor and the cold oil recharge amount.
Use only Carrier approved compressor oil. Oil should be
visible in compressor oil sight glass. An acceptable oil level is
from
1
/
8
to
3
/
8
of sight glass. All compressors must be off when
checking oil level. Oil levels above the recommended level
can lead to poor system performance.
Adding Oil
— Add oil to the oil equalizer Schrader valve on
tandem compressor sets and the compressor Schrader valve on
trio and single compressor circuits. (See Fig. 175 and 176.)
When oil can be seen at the bottom of the sight glass, add oil in
5 oz (0.15 L) increments, each of which is approximately
1
/
8
in.
(3.2 mm) oil level. Run all compressors for 20 minutes, then
shut off to check oil level. Repeat procedure until acceptable oil
level is present.
NOTE: Use only Carrier approved compressor oil. Approved
sources are:

Do not reuse oil that has been drained out, or oil that has
been exposed to atmosphere.

*Standard compressor model numbers start with ZP. Digital com-
pressor model numbers start with ZPD.
CAUTION
The compressor in a Puron
®
refrigerant (R-410A) system
uses a polyolester (POE) oil. This is extremely hygro-
scopic, meaning it absorbs water readily. POE oils can
absorb 15 times as much water as other oils designed for
HCFC and CFC refrigerants. Take all necessary precau-
tions to avoid exposure of the oil to the atmosphere. Failure
to do so could result in possible equipment damage.
