Before operating this unit, please read this
manual thoroughly. You must understand the
procedures outlined in this manual. Failure to
follow these procedures could void all war-

Before handling refrigerants, read the material
safety data sheet (MSDS) from the refrigerant
manufacturer.
Inhalation of high concentration of refriger-
ant vapors is harmful and may cause heart
irregularities, unconsciousness, or death.
Deliberate inhalation of refrigerants is ex-
tremely dangerous. Death can occur without
warning. Vapors reduce oxygen available
for breathing and are heavier than air. De-
composition products are hazardous. Liquid
contact can cause frostbite. All refrigerant
containers, equipment, and hoses are under
pressure.
