Warning Be sure to wait for 10 minutes or more after turning off all power
supplies before disassembling work.
Procedure
Discharge side
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
Compressor
refrigerant oil in the
compressor catches fire,
(R11889)
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
(R12031)
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.
