SPECIAL PROCEDURE IN THE CASE OF MOTOR COMPRESSOR BURNOUT

WARNING

ELECTRIC SHOCK HAZARD

Turn off electric power before service or installation.

Failure to do so may result in personal injury, or death.

WARNING

HIGH PRESSURE HAZARD

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.

WARNING

EXPLOSION HAZARD

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.

1.Recover all refrigerant and oil from the system.

2.Remove compressor, capillary tube and filter drier from the system.

3.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.

4.Reassemble the system, including new drier strainer and capillary tube.

5.Proceed with step 8-10 on previous page.

ROTARY AND SCROLL COMPRESSOR SPECIAL TROUBLESHOOTING AND SERVICE

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.
