Turn off electric power before service or 

installation.

Failure to do so may result in personal injury, 

or death.

Sealed Refrigeration System contains refrigerant 

and oil under high pressure.

Proper safety procedures must be followed, 

and proper protective clothing must be worn 

when working with refrigerants.

Failure  to  follow  these  procedures  could 

result in serious injury or death. 

The use of nitrogen requires a pressure

regulator. Follow all safety procedures and 

wear protective safety clothing etc. 

Failure to follow proper safety procedures 

result in serious injury or death. 

Recover all refrigerant and oil from the system.  

 

Remove compressor, capillary tube and filter drier  

from the system.  

 

Flush evaporator condenser and all connecting 

tubing with dry nitrogen or equivalent. Use approved 

flushing agent to remove all contamination from 

system. Inspect suction and discharge line for 

carbon deposits. Remove and clean if necessary. 

Ensure all acid is neutralized. 

 

Reassemble the system, including new drier strainer 

and capillary tube. 

Proceed with step 8-10 on previous page. 

Basically, troubleshooting and servicing rotary compres-

sors is the same as on the reciprocating compressor with 

only one main exception:

NEVER, under any circumstances, liquid charge a rotary-

compressor through the 

LOW side. Doing so would cause 

permanent damage to the new compressor. Use a charging

adapter.
