Discharge.
WARNING
Dangerous chemical refrigerant under pressure is used in the operation of this equipment. Use
great care to avoid contact with liquid refrigerant.
Sudden and irreversible tissue damage can result from freezing. Wear gloves and a face
protector or safety glasses in any situation where skin or eye contact with refrigerant is possible.
Heat causes the refrigerant to break down and form carbonyl chloride (phosgene), a highly toxic
and corrosive gas. Prevent contact of refrigerant with flame or hot surfaces.
NOTE
Venting chlorofluorocarbon refrigerants into the atmosphere rather than recovering them is a
violation of public law and subject to severe penalties.
