Important NOTES: These R-410A
compressors use a polyolester (POE)
lubricant. Types of recommended POE
oil are Copeland Ultra 22 CC, Copeland Ultra
32 CC, Copeland Ultra 32-3MAF, Mobil EAL,
Arctic 22 CC, Uniqema Emkarate RL32CF, or
Uniqema RL32-3MAF.
POE oil absorbs moisture much quicker
and to a greater degree than standard
mineral oil. The compressor must not
be left open longer than 15 minutes
during replacement. During installation
the system must be swept with an
inert gas such as dry nitrogen to keep
moisture from entering the compressor
and prevent the formation of oxides.
4, follow procedures indicated for burnout cleanup.
Dispose of oil and compressor using an approved environmentally safe
disposal method.

Step 3. Mount the Replacement Compressor
Do not remove the dust cover or rubber shipping plugs until all other system
connections are complete (i.e. new liquid line filter drier(s) installed and all tubing
changes made - see Steps 4 and 5). The amount of time the compressor is open
to the atmosphere must be kept to a minimum.
Use the new mounting grommets and sleeves that are shipped with the
compressor to mount it. The sleeves will prevent over compression of the
grommets. Re-use the mounting bolts from the compressor that was removed. The
mounting bolts will bottom out when tight.
•
Step 4. Install New Filter Driers (Select procedure that applies.)
IF the oil measured in Step 2 was not significantly less than the amount shown in
the table above or the test for acid in Step 2 did NOT indicate burnout , install
a new R-410A refrigerant liquid line filter drier. The filter drier must be rated for
no less than 600 psig and be the proper size for the circuit. Because R-410A
refrigerant requires POE oil which absorbs moisture quickly, it is important to
change the filter drier any time the circuit is opened.
It is recommended to use a tubing cutter when cutting out a filter drier as the
desiccant absorbs and holds moisture better when it is cool. Heat from a torch
may cause moisture to leave the filter and be absorbed in the oil. Be careful to
keep dirt, filings, and other contaminants out of the system.
Continue to
Step 5.
IF the oil measured in Step 2 was significantly less than shown in the table above
or the test for acid in Step 2 did indicate compressor burnout, do the following:
a) Install a liquid line filter drier. If there is acid, install an acid removing filter
drier. Size the acid-removing filter drier at least one capacity size larger than
normally required for the circuit.
b) Install a temporary filter drier in the suction line. When there is acid, a 100%
activated alumina suction filter drier is recommended. The suction line drier
should be sized properly for the circuit and have a service access fitting to
monitor pressure drop across the drier. (NOTE: Suction line filter drier must be
removed after 72 hours of operation.)

lower than listed in the table on page 14, clean the excess oil through use
of suction and liquid line filter driers. Beginning in Step 4, follow the same
procedure as for burnout cleanup.
Use an acid test kit to check the oil for acid. If acid is found, beginning in Step
