BEFORE USING IT.
To install and preparation before using
WARNING
1．Always ground the unit
・Connect the grounding cable to your ground conductor or ground terminal
・Do not forget to ground the Oven, to protect you and the unit from electrical shock in
case of power surge
・Do not connect the grounding wire to a gas pipe, or by means of a lightning rod or
telephone line. A fire or electrical shock will occur.
NOTE: The oven has not a plug connected because of the 220V specification
2．Choose a proper place for installation.
・Do not install the oven in a place where:
・ Flammable gas or corrosive gas is generated.
・ Ambient temperature exceeds 35℃
・Ambient temperature fluctuates violently.
・There is direct sunlight.
・There is excessive humidity and dust.
・There is a constant vibration.
・Keep the following clearance around the oven.
1ｍand more
60cm and more
60cm and more
more
1ｍand more
3. . Operation with ventilation
When using this machine with ventilation (with Damper opened) it is required to make
sure of full ventilation around the place. Without enough ventilation around the machine a
hot flats from its exhaust opening will raise room temperature or the room can be filled with
smoke and gas discharged from its materials. Therefore do not forget to connect an exhaust
duct at its exhaust opening in order to discharge a blast wind outside. We can offer exhaust
pipe flange and exhaust dust as an option by request.

Model DF610 AC200V Single phase 16A
Model DH410 AC200V Single phase 14A
Model DH610 AC200V Single phase 20A
・Do not connect the oven to an outlet that differs from the above specifications because a fire or
electrical shock will occur
5.Supply connections for the oven
・Request the supply connection for the 200V specifications from a licensed electrician.
・Failure to have this operation complete by certified personnel will cause a fire or
electrical shock during Oven operations.
6.Do not use the unit in an area where there is flammable or explosive gas.
・Never use the unit in an area where there is flammable or explosive gas.The unit is
not explosion-proof. An arc may be generated when the power switch is turned ON or
OFF,and fire/explosion may result.

BEFORE USING IT
･ Requirements for Installation
CAUTION
Handling of power code.
・Do not use the power cord if it is bundled or tangled. If it is used in this manner, it
can overheat and fire may be caused.
・Do not process, bend, wring, or stretch the power cord forcibly. Fire or electrical
shock may result.
・Do not put the power cord under the desk,chair,etc.,or through an object. Fire or
electrical shock may be caused.
・Do not run the power cord next to heating equipment such as a heater. The cover of
the cord may melt and fire or electrical shock may result.
・When the power cord is damaged (exposure of the core wires,disconnection,etc.),turn
off the power key right immediately,then turn off the circuit breaker and the main
power.Contact customer service for a replacement immediately. If this procedure is
not followed,fire or electrical shock may be caused.
Caution in setting shelves
・Do not use any shelves but the attached ones.
・If it is used in this manner, the oven cannot occasionally regulate temperatures
properly.
・Put the attached shelves on the shelf brackets fitted to the chamber when you use
the oven.

10
PRECAUTIONS IN HANDLING
WARNING
Substances that Can be used
・Never use explosive substances (shown on page 34) , flammable substances (shown on
page 34) and substances that include explosive or flammable ingredients in the unit
Explosion or fire may occur
Do not put the foreign substances in the oven
・Do not put a foreign substances such as metals or flammable substances in the
opening of the unit (ventilation hole and exhaust port, etc.). If this procedure is not
followed, fire, electrical shock or burn may result
・If the foreign substances enter the unit, turn off the circuit breaker immediately and
contact a service technician for inspection. If this procedure s not followed, fire,
electrical shock or burn may result
Caution in taking out a samples
・During and immediately after operation the internal surfaces of the chamber and the
door are extremely "HOT". To prevent injury take out the samples when the
chamber has cooled down or wear gloves while the chamber is still hot
When you open the door during working at the high temperature.
・Do not touch the internal surfaces of the chamber and the door when you will open the
door, because they are extremely hot.
・To open the door while the chamber is still hot may cause the malfunction of a fire
detector if it is installed near the oven.
Do not touch heated parts .
・Do not touch the door during or immediately after operation. Severe burning injury
may be caused due to the high temperature
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
Do not put anything on the oven
・Do not put anything on top of the oven because they will fall and result in injury to a
person.

11
Precautions in handling
CAUTION
Caution about the temperature range.
・Use the oven in the range of 40℃to 210℃
When you use the oven for the first time
・During the initial operation, the oven may occasionally generate an odor especially when
high temperatures are resched. This odor is nomal and does not signal a problem with the
oven. The nature of the odor is caused by the adhesive on the insulation melting
About the temperature in the chamber
・Temperature display indicates the sensor temperature installed in the unit, however it
does not always correspond to the tempwrature of the sample when the sample volume is
very large or when the temperature is on the increase.
Caution about a drenched sample
・When using a very wet sample, try to drain it as much as possible before putting it in
chamber.
Caution about powdery sample and the loading of samples
・There are times when a powder sample is scattered by the sudden decompressin
operation or purge operation. When performing decompression or purge,open the valve
very slowly.
・It occasionally takes a long time before the chamber reaches the target temperature if
the chamber is congested with samples with the large specific heat is in it.
In such cases, reduce samples. Moreover, note that the temperature display
occasionally unsettle when you process a exothermic sample.
Distribute samples
・Each shelf can carry a uniform load of 15 kg(33 lb.). When you place samples on a shelf,
distribute them evenly over the shelf area.
・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.

12
Precautions in handling
CAUTION
Never use corrosive samples
・Most parts are made of stainless steel(SUS304). However, strong acid occasionally
corrodes even stainless steel. Besides this,
・The silicone rubber packing is also vulnerable to acid, alkali, oil and halogen’s solvent
Install the Oven on a level area
・Do not installation the oven on a non level surface. This will cause hazards to the
operator and create problems during actual operation.

13
Precautions in handling
CAUTION
Do not place any samples on the bottom of the chamber
・Do not place any samples on the bottom of the chamber to heat, because it affects the
temperature control of the oven.
・Always put the samples on the attached shelves. Place sample so that it does not
touch the interior wall of the chamber
・Set the shelves on the shelf brackets that will accommodate the size of the sample
Durinq a thunder storm
・During a thunder storm, turn off the power key immediately, then turn off the
circuit breaker and main power. If this procedure is not followed, fire or electrical
shock may be caused
when having a blackout
・Once the power supply is recovered, the oven can resume when it stopped because of
having a blackout
When you open and shut the door
・Do not put your hand either face near the door when you open and shut the door.
Failure to observe this caution may result in injury because the door hits your hand
or face.
