Refrigerant Properties
HCFC-22 or HFC-134a is the standard refrigerant in the 19XL. At normal atmospheric
pressure, HCFC-22 will boil at –41 F (–40 C) and HFC-134a will boil at –14 F (–25 C) and must,
therefore, be kept in pressurized containers or storage tanks. The refrigerants are practically
odorless when mixed with air. Both refrigerants are non-combustible at atmospheric pressure.
Read the Material Safety Data Sheet and the latest ASHRAE Safety Guide for Mechanical
Refrigeration to learn more about safe handling 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.
