PRECAUTIONS IN HANDLING
CAUTION
1. When operating the unit for the first time
When you use the unit for the first time, a strange odor may generate at a higher
temperature. This is due to decomposed binding agent contained in the heat insulator and
does not indicate a malfunction of the unit.
2. If you fully open the exhaust duct
The maximum operating temperature will not be reached if you fully open the exhaust
duct.
3. When processing a sample that contains moisture
When you want to process a sample that contains moisture, open the exhaust damper;
raise the temperature to remove moisture. When water exists inside the unit, an electric
shock or a malfunction of the unit may result.
4. About processing of a sample
To improve temperature distribution within the bath, the unit employs air blow
circulation. When processing powder sample or a small sample, make sure that the
sample will not scatter. Entering of a flammable material or a metal into the heater
assembly may cause a fire or an electric shock.
Some time may be necessary for the temperature to rise when processing a large amount
of sample or a sample with a larger thermal load. Confirm a correct amount as necessary
and set the sample. Note that the indicated temperature may become unstable when
processing a heat-generating sample [note however, the sample must be free of risk of
explosion, firing, or ignition of itself (whose density is less than the explosion limit
density).
5. Distribute samples
The withstand load of each shelf board included with the unit is about 30kg. Do not put
any sample that exceeds this load.
Set two or more samples as dispersed as possible.
If a shelf is congested with samples, the oven occasionally cannot regulate temperatures
properly. To ensure the oven’s temperature accuracy, there should be open space of at
least 30% on each shelf.
6. Do not climb on the oven
Do not climb on top of the oven because it will fall down and break. Failure to observe
this caution may cause injury to a person
