Remove the putty.
2. Remove the four way
valve.
Caution
Be careful not to get yourself
burnt with the pipes and
other parts that are heated by
the gas brazing machine.
Caution
From the viewpoint of global
environment protection, do
not discharge the refrigerant
gas in the atmosphere. Make
sure to recover the
refrigerant gas with the
recovery system.
Reassembling precautions
1. Use non-oxidizing brazing
method. If nitrogen gas is
not available, braze the
parts speedily.
2. Avoid deterioration of the
gaskets due to
carbonization of oil inside
the four way valve or
thermal influence. For this
purpose, wrap the four way
valve with wet cloth. Splash
water over the cloth against
becoming too hot (keep it
below 120°C).
In pulling the pipes, be
careful not to over-tighten
them with pliers. The pipes
may get deformed.

Be sure to apply
nitrogen
replacement when
