Removal Procedure
4
Unscrew the 3 nuts of
the compressor.
2. Remove the compressor.
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. Avoid excessive heating.
(Keep below 120°C)
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.
Heat up the brazed part
of the suction side and
disconnect.
3
Lift the compressor up
and remove it.
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.
