Use a high temperature torch to disconnect the suction line and the discharge line from
the compressor.
d) Remove the mounting bolts and the compressor. Save the mounting hardware to
attach the grommets and sleeves shipped with the replacement compressor.
e) To test for acid and to assure excess oil does not remain in the circuit, remove oil
from the failed compressor. Measure the amount of oil.
CAUTION: In addition to the required eye protection and gloves, care
should be taken in handling POE oil because it may cause damage to
certain plastics and roong materials. See Hazard Levels, page 2.
If the oil taken from the compressor and measured is found to be signicantly
lower than listed in the table below, clean the excess oil through use of suction
and liquid line lter 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 4,
follow procedures indicated for burnout cleanup.
Dispose of oil and compressor using an approved environmentally safe disposal
method.

Important NOTES: These
R-410A compressors use a
polyester (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.

• 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 lter 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 signicantly 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 lter drier. The lter 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
