Precautions in Handling
Caution
1. When you use the oven for the first time
During the initial operation, the oven may occasionally generate an odor especially when
high temperature are reached. This odor is normal and deose not signal a problem with the
oven. The adhesive on the insulation melting causes the nature of the odor.
2. When you open the exhaust duct to its full width
When you open the exhaust duct to its full width, the time toward the maximum high
temperature to use and air cleanliness may not be satisfied with class 100. When you open
the inhalation port to its full width, it may not reach to the maximum high temperature to
use.
3. Caution about a drenched sample
When using a wet sample, try to drain it by heating it by heating with the ventilation damper
opened. If water is adhered to the inside of the unit, it may cause electric shock, machine
trouble, or weakness of HEPA filter.
Do not use a very wet sample as it is.
4. Caution about samples
To be uniform the temperature distribution in the chamber, it is circulated whit the
ventilation. When you use a powder sample or a small sample, be sure not to be scattered,
if the flammable materials or metal to in the heater, it may cause fire ir electric shock.
It occasionally takes a long time before the chamber reaches the target temperature if the
camber is congested with samples or a sample with the large specific heat is in it. In such
cases, reduce samples. Moreover, note that the temperature display occasionally unsettle
when you process the sample that generate heat (Only the case that the sample itself is not
explosive, combustible, or ignitable substances).
5. Distribute sample
Each shelf can carry a uniform load of 30
㎏
. Do not put heavier sample than it.
When you place samples on a shelf, distribute them evenly over the shelf area.
If a shelf is congested with sample, 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.
