The R22 refrigerant system is pressurized. To prevent injury to personnel, gloves and eye
protection must be worn when working on R22 refrigerant system.
Prevent contact of R22 refrigerant with flame or hot surface. Heat causes R22 refrigerant to
break down and form carbonyl chloride (phosgene), a highly toxic and corrosive gas.
R22 refrigerant must be recovered. Venting R22 refrigerant into the atmosphere is a
violation of public law and subject to severe penalties.
Do not attempt to remove or connect refrigerant servicing equipment while ECV is running.
Failure to observe these warnings can result in injury to personnel.
Cover or plug all openings immediately after removal of compressor to prevent
contamination. Remove all covers/plugs prior to reconnecting.
NOTE
This procedure covers the replacement of the following components: compressor, motor, high
pressure switches HPS1 and A1RMPS1, and bulkhead access valves.
Remove/disassemble only to the extent necessary to remove or replace defective
assemblies/components. Use standard maintenance shop practices/procedures.
a. Removal (Refer to Figure 3-20)
(1)
Disconnect two tube assemblies (1 and 2) from compressor (3).
