Use a field-provided acid test kit (be sure the kit is designed for the

appropriate refrigerant) to check the oil for acid. If acid is found, begin-

Step 4 follow the procedures indicated for burnout cleanup.

CAUTIONS: The compressor may contain harmful acids. Be

sure to handle with extreme care using proper protective

equipment. After testing for acid and checking the oil charge

level, return the oil to the compressor being replaced. Braze

the discharge and suction copper closed. Use an approved

disposal method to dispose of the compressor and the oil.

Step 3. Mount the Replacement Compressor

Do not remove the dust cover or rubber shipping plugs until all other sys-

tem 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 should 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 the procedure that applies.)

If the test for acid in

Step 2 did NOT indicate burnout, install a new liquid

line filter drier. The filter drier must be the proper type and size for the cir-

cuit. Install a temporary field-supplied suction line filter drier.
