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 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 signicantly 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

change the lter drier any time the circuit is opened.

It is recommended to use a tubing cutter when cutting out a lter drier as the

desiccant absorbs and holds moisture better when it is cool. Heat from a torch

may cause moisture to leave the lter and be absorbed in the oil. Be careful to

keep dirt, lings, and other contaminants out of the system.

Continue to Step 5.

IF the oil measured in Step 2 was signicantly 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 lter drier. If there is acid, install an acid removing lter

drier. Size the acid-removing lter drier at least one capacity size larger than

normally required for the circuit.

b) Install a temporary lter drier in the suction line. When there is acid, a 100%

activated alumina suction lter drier is recommended. The suction line drier

should be sized properly for the circuit and have a service access tting to

monitor pressure drop across the drier. (NOTE: Suction line lter 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 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
