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

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

1. Restore the piping by nonoxidation brazing.

In case of you cannot use the nitrogen gas, restore as quickly as possible.

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 will not be dried and avoid excessive heating. (Keep below 120°C)

Be careful so as not to break the pipes by pressing it excessively by pliers when withdrawing it.

In case of the difficulty with gas brazing machine

1. Disconnect the brazed part where is easy to disconnect and restore.

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

Warning: Since it may happen that refrigeration oil in the compressor will catch fire, prepare wet cloth so as to extinguish fire immediately.

Warning: Ventilate when refrigerant leaks during the work. (If refrigerant contacts fire, it will cause to arise toxic gas.)

Caution: Be careful not to get yourself burnt with the pipes and other parts that are heated by the gas welding rod.

Disconnect the flagshaped terminals.
