184 Removal Procedure
2.6 Removal of Compressor
Procedure Warning Be sure to wait 10 minutes or more after turning off all power supplies
before disassembling work.
Step
Procedure Points
1. Remove the compressor.
1
Unscrew the nut of the
compressor.
Before working,
make sure that the
refrigerant is empty
in the circuit.
Be sure to apply
nitrogen
replacement when
heating up the
brazed part.
Warning
Ventilate when refrigerant
leaks during the work.
(If refrigerant contacts fire, it
will cause to arise toxic gas.)
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 or
the name plate.
Be careful so as not to burn
the heat exchanger fin.
Warning
Since it may happen that
refrigeration oil in the
compressor will catch fire,
prepare wet cloth so as to
extinguish fire immediately.
In case of the difficulty with
gas brazing machine
1. Disconnect the brazed part
where 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. For the
sake of this, wrap the four
way valve with wet cloth and
provide water so that the
cloth will not be dried and
avoid excessive heating.
(Keep below 120°C)
Note: Do not use a metal
saw for cutting pipes by all
means because the sawdust
come into the circuit.
2
Heat up the brazed part
of the discharge side
and disconnect.
