Removal Procedure 176
 Before proceding, make sure
there is no refrigerant gas
left in the refrigerant pipes.
Caution
Be careful not to burn yourself
with the pipes and other parts that
are heated by the gas welding
rod.
Warning
If refrigerant gas leaks during the
job, ventilate the room. If the
refrigerant gas is exposed to
flames, noxious gas may be
generated.
Reassembling precautions
Wrap the four-way valve with wet
cloth. Splash water over the cloth
before it dries to prevent the valve
from being overheated.

Disconnect the 2 brazed
points, first (e), and then
(f).
Remove the defrost
solenoid valve.
Note:
 Do not use a metal
saw for cutting pipes
because sawdust
enters the circuit.
 When withdrawing the
pipes, be careful not to
pinch them firmly with
pliers. The pipes may
get deformed.
 Provide a protective
sheet or a steel plate
so that the brazing
flame cannot influence
peripheries.
