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.
If the oil taken from the compressor and measured is found to be significantly
lower than listed in the table above, 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 4, follow procedures indicated for burnout cleanup.
Dispose of oil and compressor using an approved environmentally safe
disposal method.

 Step 2. Determine Cause of Initial Failure (cont'd)
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.
