Removal Procedure 9
3. Capillary Tube
Warning Be sure to wait for 10 minutes or more after turning off all power supplies before
disassembling work.
Be careful not to get yourself burnt with the pipes and other parts that are heated by
the gas brazing machine.
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.
Restore the piping by non-oxidation brazing.
Note 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.
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 outdoor
heat exchanger fin.
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.

Warning Be sure to wait for 10 minutes or more after turning off all power supplies before
disassembling work.
Be careful not to get yourself burnt with the pipes and other parts that are heated by
the gas brazing machine.
If the refrigerant gas leaks during work, ventilate the room. (If the refrigerant gas is
exposed to flames, toxic gas may be generated.)
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.
Restore the piping by non-oxidation brazing.
Note Before working, make sure that the refrigerant gas is empty in the circuit.
