Removal Procedure 137
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 peripheries.
Warning
If refrigerant gas leaks during
the work, ventilate the room.
(If the refrigerant gas is
exposed to flames, toxic gas
may be generated.)
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
refrigerant oil in the
compressor catches fire,
prepare wet cloth so as to
extinguish fire immediately.
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.
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 does not dry and avoid
excessive heating. (Keep
below 120°C)
Note: Do not use a metal
saw for cutting pipes by all
means because the sawdust
comes into the circuit.
Remove the four
way valve, the
terminal cover and
the lead wire for
compressor so as
not to burn them.
1
Unscrew the 3 nuts of
the compressor.
2. Remove the compressor.

of the discharge side
and disconnect.
Heat up the brazed part
of the suction side and

Caution
From the viewpoint of
global environment
protection, do not
discharge the
refrigerant gas in the
atmosphere. Make
sure to recover the
refrigerant gas with
the recovery system.
Caution
From the viewpoint of
global environment
protection, make sure
to use a vacuum
pump for air purging.
