Warning
Be careful not to burn yourself
with the pipes and other parts
that are heated by the gas
brazing machine.
Warning
If the refrigerant gas leaks
during work, immediately
ventilate the room. (If the
refrigerant gas is exposed to
flames, toxic gas may be
generated.)

protection, do not discharge
the refrigerant gas in the

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
(R17407)
248°F(120°C). 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
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.
