Points
Caution
Never remove the electronic
expansion valve because it
contains plastic parts.
They may melt with heat and
cause operation failure.
Replace the whole assembly.
Caution
Do not directly heat the
electronic expansion valve. Wrap
the electronic expansion valve
with a wet cloth and provide
water so that the cloth does not
dry. Keep below 120°C (248°F).
Warning
Be careful not to burn yourself
burnt with pipes and other parts
that are heated by the gas
brazing machine.
Warning
If the refrigerant gas leaks during
work, ventilate the room. If the
refrigerant gas is exposed to
flames, toxic gas may be
generated.
Caution
For global environment
protection, do not discharge the
refrigerant gas in the
atmosphere. Make sure to collect
all the refrigerant gas.
