15. Placing shelf boards and specimens
Shapes of shelf boards will differ depending on the model and each model contains two or
four boards. One of them has been fixed on the lowest stage of the shelf peg pillars inside the
unit with screws at the time of factory shipping. Set the remaining shelf boards to appropriate
positions in the unit.
One of the shelf boards has been
fixed on the lowest stage of the shelf
peg pillars inside the unit with screws
at the time of factory shipping.
A heater and a fan are installed under
the rectifier plate. And temperature of
the rectifier plate and around it is
always higher
temperature and if you place a
specimen directly on the plate, it may
burn or a fire may result.
Slit at the front side of the rectifier
plate is the suction slit of the hot air
convection route. Never block this slit
with a specimen or other objects.
For this reason, the shelf boards are
held with screws as shown in the
drawing to prevent specimens from
being placed directly.
If you need to remove shelf boards
due to the shape of a specimen to
set, secure sufficient space to the
rectifier plate and never place the
specimen directly.
16. When using a wet material
Drain off well the water of wet material before putting it in chamber in case to dry
it.Otherwise, it may cause dew condensation or excessively high humidity and cause harm
to electrical system. Be careful that it may cause malfunction.
17. About handling of the exhaust port (manual damper)
The exhaust port is located at the rear of the main unit. While the manual damper is used, hot
air will be exhaust at the port. So be sure to connect the exhaust duct and assure sufficient
space behind the back of the main unit. The exhaust port and around it will become hot and
take sufficient care for burning.
Exhaust port flange dia.：Φ80mm
Air amount when damper is fully opened（environmental temp.：23℃, at no load, in-bath
temp：25℃）
DKG610(V)，DKG650(V)：1.5 ㎥/min
DKG810(V)，DKG850(V)：1.4 ㎥/min
About ventilating operation
When you attempt to increase temperature with the manual damper open, note that the
target temperature may not be reached depending on the openness of the damper, the
environmental temperature, or the amount of specimen.
（Temperature can be raised up to 260℃ at environmental temp：23℃， no-load, and up to
50% of damper openness. Note that the temperature rise time is not guaranteed.）
