Warning

Š

Be sure to wait for 10 minutes or more after turning off all power supplies before 
disassembling work.

Š

Be careful not to get yourself burnt with the pipes and other parts that are heated by 
the gas brazing machine.

Š

If the refrigerant gas leaks during work, ventilate the room. (If the refrigerant gas is 
exposed to flames, toxic gas may be generated.)

Š

Since it may happen that the refrigerant oil in the compressor catches fire, prepare wet 
cloth so as to extinguish fire immediately.

Caution

Š

From the viewpoint of global environment protection, do not discharge the refrigerant 
gas in the atmosphere. Make sure to collect all the refrigerant gas.

Š

Restore the piping by non-oxidation brazing.

Note

Š

Before working, make sure that the refrigerant gas is empty in the circuit.

Š

Be sure to apply nitrogen replacement when heating up the brazed part.

Š

Do not use a metal saw for cutting pipes by all means because the sawdust comes into 
the circuit.

Š

When withdrawing the pipes, be careful not to pinch them firmly with pliers. The pipes 
may get deformed.

Š

Provide a protective sheet or a steel plate so that the brazing flame cannot influence 
peripheries.

Š

Be careful so as not to burn the compressor terminals, the name plate, the outdoor 
heat exchanger fin.

Š

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.
