Removal of Compressor ASSY

Removal Procedure

15

4

Remove the 4 nuts of 
the compressor.

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. Avoid excessive heating. 

(Keep below 120°C)

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.

„

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.

5

Heat up the brazed part 
of the discharge side 
and disconnect.

6

Heat up the brazed part 
of the suction side and 
disconnect.

7

Lift the compressor 
ASSY up and remove it.

Note:

„

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 heat exchanger fin.
