SiUS091133 Outdoor Unit: RXS09/12LVJU
Removal Procedure 286
3
Disconnect the lead
wires of the
compressor.
4
Remove the screw and
remove the four-way
valve coil.
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 (248°F).) For the sake of
this, wrap the four-way valve
with wet cloth and provide water
so that the cloth does not dry.
5
Remove the sheets of
putty.
