Removal Procedure
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.
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.)
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.
2. Remove the four way
valve and electronic
expansion valve.
1
Heat up the 2 brazed
parts of the electronic
expansion valve and
remove it.
2
Heat up the brazed
parts of the four way
valve.
3
Pull the pipe with pliers
and disconnect.
