381 Removal Procedure

Before working, make
sure that the refrigerant
gas is empty in the circuit.

Be sure to apply nitrogen
replacement when
heating up the brazed
part.
Warning
Use caution to avoid burning
yourself with 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 refrigerant gas is
exposed to flames, toxic gas may
be generated.
Warning
If the refrigerant oil in the
compressor catches fire, have a
wet cloth prepared to extinguish
the fire immediately.
Caution
For global environmental
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 (248°F). Wrap the four-
way valve with a 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.
4 Heat up the brazed part
and withdraw the piping
with pliers.
5 Remove the 3 nuts.
Note:

Never use a metal saw for
cutting pipes or sawdust
will enter the circuit.

When withdrawing the
pipes, be careful not to
pinch them firmly with
pliers. The pipes may get
deformed.

Provide a protective sheet
or a steel plate so that the
brazing flame cannot
influence peripheries.

Be careful so as not to
burn the compressor
terminals, the name plate,
the heat exchanger fin.
