Removal Procedure 288
4.7 Removal of Compressor
Procedure Warning Be sure to wait for 10 minutes or more after turning off all power supplies
before disassembling work.
Step
Procedure Points
1
Remove the 2 nuts of
the compressor. Warning
Be careful not to get yourself
burnt with 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 (248°F).) 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.
 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.
2
Heat up the brazed part
of the discharge side
and disconnect it.
