136 Removal Procedure
2
Heat up the 3 brazed
points of the four way
valve. Disconnect the
point (b) first.
If the gas brazing machine fails
to remove the four way valve,
take the steps below.
1. Disconnect the brazed pipe
sections that are easy to
separate and join together
later.
2. With a tube cutter, cut off the
internal pipes to easily take
out the four way valve.
Note: Do not use a metal
saw for cutting pipes by all
means because the sawdust
comes into the circuit.
3
Disconnect the points
(c) and (d).
Warning
If refrigerant gas leaks
during the work,
ventilate the room. (If
the refrigerant gas is
exposed to flames,
toxic gas may be
generated.)
