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.
1
Heat up the brazed
point (a) and withdraw
the piping with pliers.
2
Heat up the 3 brazed
points of the four way
valve. Disconnect the
point (b) first.
3
Disconnect the points
(c) and (d).
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.
