Removal Procedure
133
"
Begin your work after
recognizing complete
empty of refrigerant in the
refrigerant circuit.
Caution
Be careful about four-way
valve, pipes and so on, which
were heated up by a gas
brazing machine, so as not to
get burnt on your hands.
Cautions at the restoration.
1. Restore the piping by non-
oxidation brazing. Braze it
quickly unless nitrogen gas
can be used.
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. For the
sake of this, rap the four-way
valve with wet cloth and
make up water so that the
cloth will not be dried and
avoid excessive heating.(it
keeps below 120 degree C).
"
Be careful so as not to break
pipes by pressing the pipes
excessively by a plier when
withdrawing the piping.
4
Provide a protective
sheet or a steel plate so
that the brazing flame
can’t influence the
circumstance around
the four-way valve.
5
Heat up the four
portions of brazing
parts on the four-way
valve. Remove the four-
way valve in the order
of (a),(b),(c),(d).
6
Heat up the blazing
parts and withdraw the
pipes connected to the
four-way valve by a
plier and so on.
In case that the removal seems
to be hard;
1. Remove the piping
connection part (brazing
part) easy to remove and
restore.
2. Cut the pipes on the main
unit by a miniature copper
tube cutter in order to make
it easy to remove.
NOTE:
Don’t use a metal saw for
cutting pipes by all means
because the chips come into the
circuit.
