5. Precautions on Handling
Warning and caution
10. Do not process any corrosive samples
Do not process any samples containing corrosive chemicals even though Furnace is made of
stainless steel which this steel may be corroded by strong chemical acid, etc.
11.
The furnace body may be cracked.
・
Operating at a high temperature or opening and closing the door at a high temperature might
cause a crack in the furnace body, which will not have any adverse effects on the operation
or the performance.
・
Note that chemical reaction with the substances listed in the table below may shorten the use
life of the furnace body.

12. Take extreme care when opening the door during operation at a higher
temperature.
When you attempt to open the door during operation at a higher temperature, never touch the
door since the internal furnace or the inside of the door are hot.
Note that if a fire alarm is installed around the unit, it may go off erroneously.
13.
Opening the door at a high temperature will affect the device adversely.
Minimize opening the door when the furnace body temperature is 500
℃
or above. Opening the
door at a high temperature will adversely affect the sensor, the furnace body and the heater
lives. Radiation heat might cause damages to the operation panel and the controller.
If you cannot avoid opening or closing the door, immediately close the door after completing the
necessary work.
14.
Do not leave the door open after operation.
Do not leave the unit with the door open for the purpose of cooling the specimen quickly after
operation. Heat from inside the furnace may cause deformation of the control panel or damages
to the control devices.
15.
Take care for burning.
After operation of the unit at a high temperature, the furnace body, the inside the door and the
specimen will remain hot for some time after completion of operation.
Take care for burning if you touch these parts when putting or removing the specimen. Be sure
to put heat-resistant gloves on and handle the specimen with sufficient.
16.
Use the unit at the correct temperature.
The temperature control range is between 100
℃
and 1150
℃
(FP102/302/312/412).
Never attempt to use the unit at a temperature outside the temperature control range. Using
outside the operating temperature range may lead to a malfunction of the device or an accident.
