Cautions for restoration
(R13386)
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.
In case of difficulty with gas
brazing machine
1. Disconnect the brazed part
(R13387)
where is easy to disconnect
and restore.
2. Cut pipes on the main unit
with a tube cutter in order to
make it easy to disconnect.
