Refrigerant Properti e s
HCFC-22 or HFC-134a is th e s ta ndard refrigerant in t he 19 XL. At normal atmosph er ic
pressure, HCFC-22 wi ll boil at –41 F (– 40 C) and HFC-134a will boil at –14 F (–25 C) and must,
therefore, be kept in pres s u rized containers or s to rage tanks. The refrig er an ts are practically
odorless when mixed wit h ai r. Both refrigeran ts ar e non-combustible at at m os ph eric pressure.

Refrigeration to learn more about safe handlin g of these refrigerants.
HCFC-22 and HFC-134a will dissolve oil and some nonmetallic materials, dry the
skin, and, in heavy concentrations, may displace enough oxygen to cause
asphyxiation. In handling this refrigerant, protect the hands and eyes and avoid
breathing fumes.
