Cautions for restoration
1. Restore the piping by non-
oxidation brazing.
2. It is required to prevent
carbonization of the oil inside
the four-way valve and
deterioration of the gaskets
affected by heat (keep below
120°C/248°F) so wrap the four-
way valve with a wet cloth and
provide water to prevent it from
drying out.s
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.
Note:
 Do not use a metal saw for
cutting pipes or sawdust will
enter the circuit.
 When withdrawing the pipes, be
(R14353)
careful not to pinch them too
firmly with the pliers or it may
deform the pipes.
 Provide a protective sheet or a
steel plate so that the brazing
flame cannot influence
peripheries.
 Be careful not to burn the
compressor terminals, the name
plate, or the heat exchanger fin.
