Warning
Ventilate the area thoroughly if
refrigerant leaks during the
work. If refrigerant contacts
fire, it will cause toxic gas.
 Provide a protective sheet or
a steel plate so that the
brazing flame cannot
influence peripheries.
 Be careful not to burn the
compressor terminals or the
name plate.
 Be careful not to burn the heat
exchanger fin.
Warning
If refrigerant oil in the
compressor catches fire,
prepare a wet cloth to
(R10013)
extinguish the fire immediately.
In case of the difficulty with
gas brazing machine
1. Disconnect the brazed part
where it is easy to disconnect
and restore.
2. Cut pipes on the main unit by
a miniature copper tube cutter
in order to make it easy to
disconnect.
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. Wrap the
four-way valve with wet cloth
(R7252)
and provide water so that the
cloth does not dry and to
avoid excessive heating.
(Keep below 120°C)
Note: Do not use a metal
saw for cutting pipes because
sawdust can enter into the
circuit.
