Removal Procedure

3. Removal of Compressor

Procedure

Warning

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

Step

Procedure

Points

„

Before working, make 
sure that the refrigerant 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.)

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

1. Restore the piping by non-

oxidation brazing. 

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. (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.

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 sound 
blankets (top and 
body).

2

Disconnect the suction 
pipe and discharge pipe 
of the compressor at 
brazed sections.
