Removal of Compressor Si01-779
6Removal Procedure
3. 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
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
Be careful not to get yourself
burnt with the pipes and other
parts that are heated by the
gas brazing machine.
Warning
If the refrigerant gas leaks
during work, ventilate the
room. (If the refrigerant gas is
exposed to flames, toxic gas
may be generated.)
Warning
Since it may happen that the
refrigerant oil in the
compressor catches fire,
prepare wet cloth so as to
extinguish fire immediately.
Caution
From the viewpoint of global
environment 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.) For the sake
of this, 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.
1Remove the sound
blankets (top and
body).
2Disconnect the suction
pipe and discharge pipe
of the compressor at
brazed sections.

Si01-779 Removal of Compressor
Removal Procedure 7
3Remove the 3 nuts of
the compressor.
Note:
Do not use a metal saw for
cutting pipes by all means
because the sawdust comes
into 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.
4Lift the compressor up
and remove it.
