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 condenser coil/oil cooler to prevent
a. Removal (Refer to Figure 3-21)
