Removal Procedure 211
3
Heat the soldered
portion of the suction
side, and disconnect
the suction pipe.
Warning
If the refrigerant gas leaks
during work, ventilate the
room. (In case the refrigerant
gas is exposed to fire, it will
cause toxic gas.)
Cautions on Mounting
1. Use anti-oxidation solder for
connecting the pipe. If
nitrogen gas can not be
used, solder the pipe
quickly.
2. It is necessary to prevent the
gaskets from deterioration
due to carbonization of oil in
the four way valve or effect
of heat. Therefore, wrap the
four way valve body with wet
cloth and add water
occasionally so that it should
not get dry and the valve
should not be heated. (Keep
the valve temperature below
120°C.)
When disconnecting the
pipe, be careful not to crush
it by pliers with undue force.
If the pipe is hard to disconnect
by means of a gas welding
machine:
1. Disconnect the pipe
connection (soldered
portion) which is easy to
disconnect and reconnect.
2. Cut off the pipe of the valve
body with use of a copper
pipe cutter and disconnect it.
NOTE:
Never use a metal cutting saw
for cutting off the pipe. It
produces metallic sawdust that
may enter the pipe.
Caution
Be careful not to get burned
by the pipe heated by the gas
welding machine.
Caution
From the point of view of
environmental protection, do
not release the refrigerant
gas to the atmosphere in
repairing the refrigerant
circulating system, but
always collect it with use of a
collecting device.
4
Remove the
compressor by lifting it
up.
