Compressor Removal

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

Remove the 2 nuts of the compressor.

Warning: Be careful not to get yourself burnt with 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

Restore the piping by nonoxidation brazing.

It is required to prevent the carbonization of the oil inside the four way valve and the deterioration of the gaskets affected by heat. (Keep below 120°C.) For the sake of this, wrap the four way valve with wet cloth and provide water so that the cloth does not dry.
