Si01-982 Removal of Capillary Tube
Removal Procedure 13
5. Removal of Capillary Tube
Procedure Warning Be sure to wait for 10 minutes or more after turning off all power
supplies before disassembling work.
Step Procedure Points
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.
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.)
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.
1 Remove the putty. Heat
up the 2 brazed parts
and remove the
capillary tube.
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.

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.
