3) To collect waste in the deep bottom area of the furnace and the wax receiver, use a crevice
tool nozzle of vacuum cleaner. In the case a vacuum cleaner available on the market is used,
use it with a crevice tool nozzle.
4) Remove and clean the drain orifice periodically.
CAUTION
If wax is not drained smoothly (a large amount of wax remains inside the furnace) because of
clogging etc., a large amount of gas over combustion capability of the afterburner may be
generated, and incomplete combustion gas (black gas) may blow out from exit of the afterburner.
4-3. CHECKING CRACK OF ADIABATIC MATERIAL
Cracks in the door frame should be repaired with adhesive (P.48) at its early stage.
4-4. CHECKING DEFORMATION OF TURNTABLE
If the turntable is deformed by deterioration, the flask may tilt, resulting an accident such as
short-circuit or damage of the heater etc.
If deformation has become so large that the flask may tilt, replacement of the turntable is
necessary.
From the same reason, a deformed flask should not be used.
When you set flasks in the furnace, repeat rotation and stop of turntables for several times to
make sure that the flasks will not tilt. Then, start automatic burnout operation.
(The turntables are used in high temperature environments, so their deterioration speed
depends on individual using frequency and conditions.)
