(main)
burnt with the pipes and other
parts that are heated by the
gas brazing machine.
If the refrigerant gas leaks

exposed to flames, toxic gas
(subcooling)
may be generated.)
From the viewpoint of global
environment protection, do
not discharge the refrigerant
gas in the atmosphere. Make

sure to collect all the
refrigerant gas.
Cautions for restoration
1. Restore the piping by non-
oxidation brazing.
2. It is required to prevent the
carbonization of the oil inside
the four way valve and the
deterioration of the gaskets
affected by heat. (Keep
below 120°C.) For the sake
of this, wrap the four way
valve with wet cloth and
provide water so that the
cloth does not dry.
