WARNING

Dangerous Pressurized Chemical Refrigerant is used in the operation of this

equipment

Avoid contact with liquid refrigerant or inhaling refrigerant gas being discharged from

any container under pressure. Sudden and irreversible tissue damage can result from

freezing. Wear thermal protective gloves and a face protector or safety glasses in any

situation where skin or eye contact is possible.

Heat causes the refrigerant to break down and form carbonyl chloride (phosgene), a

highly toxic and corrosive gas. Prevent contact of refrigerant gas with a flame or other

hot surfaces.
