Refrigerant Properties
HFC-134a is the standard refrigerant in the 17/19EX. At normal atmospheric pressure,
HFC-134a will boil at -14 F (-25 C) and must, therefore, be kept in pressurized containers or
storage tanks. The refrigerant is practically odorless when mixed with air. This refrigerant is
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 this
refrigerant.
HFC-134a will dissolve oil and some non-metallic 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.
