NOTE

Special Instructions for Replacement of Burned-Out Compressor.

A compressor motor burn-out seriously contaminates the refrig-

erant system with acids and gummy residue that will cause suc-

cessive burn-outs unless the following procedure is followed:

a. To determine if the compressor motor is burned-out,

release a small amount of refrigerant through the service

valve. Refrigerant from a burned compressor motor will have

a strong, peculiar odor.

b. Release remainder of refrigerant (para 74).

c. Remove expansion valve internal parts (figure 12).

d. Connect a refrigerant drum to the flare connection

normally connected to the compressor suction and open the re-

frigerant drum momentarily flushing burned residue.

e. Connect the drum to the discharge line connection and

purge the high side of the system.

Remove refrigerant drum.

Install new compressor (para 76).

h. Clean and replace expansion valve internal parts.

i. Install new strainer dehydrator (para 80).
