6. Putting samples and vessels inside the chamber
Danger
Do not use flammable materials
such as organic solvent.
Since the temperature inside the chamber
subjects to high, some sample materials may
be vaporized, and may ignited or exploded.
Ignitable materials are nitrates, nitro
compounds, etc. and explosive materials are
salt peroxides, inorganic peroxides, salt
nitrates, organic solvents etc.
This unit is not designed with explosion-
proof structure.
Caution
Caution
Check the allowable temperature
limit of the vessel.
Do not jam samples into the chamber.
Place samples evenly.
Do not block the air supplying port with
vessels. It may worsen the convection
inside the chamber and reduce
temperature uniformity, and cause
mechanical troubles.
Since the temperature inside the chamber
will be high depending on the setting
temperature, some vessels may be melted.
Check the allowable temperature limit
before starting operation.
Caution
When placing glass wares, set the
temperature carefully.
If you place glass wares into the chamber and
set the temperature at 0
℃
or lower, frozen
sample may break the glass wares and cause
you physical injury. Use extreme caution
when handling glass wares.
Handle
Sample
Shelf
Lay out evenly.
(1) Open the door.
When you pull the handle, the door lock is
released and the door is opened.
(2) Lay out samples on a shelf with keeping
uniform distance.
(The load capacity per shelf is 15kg.)
Do not block the air suction port and fan
with samples when you put them into the
chamber.
(Convection in the chamber is obstructed.
The temperature control alarm may be
activated in some cases.)
Due to the characteristics of this unit, the
moist sample is dried if no temperature
control was done. Vaporized moisture may
make dew condensation and frost.
To reduce drying of sample, cover each
vessel with a lid.

(3) Close the door gently.
If the door is not closed completely, operation
does not start. (Door alarm is displayed.)
Do not spill the samples or water when putting them into
the chamber. If you do so, it may cause a crash of the unit ,
which may lead electric shock caused by leakage.
If you spill it accidentally, wipe it off immediately.
The drain port is placed at the bottom of chamber to drain
condensed water. The condensed water cannot be drained
completely depending on the environmental condition or the
plateau of unit. Do not put samples on the bottom surface of
chamber to avoid blocking the drain port and air suction port.
Put samples on each shelf.
・
Observation window is glassware. If you damage the window,
glass may be broken and cause you physical injury.
Use care when handling it.
・
Heater for reducing dew condensation (on the chamber side)
starts working for observation window depending on setting
temperature. If the heater is turned on, door part situated
around the observation window may be in high temperature
(lower than approx. 60
℃
) . Be careful when touching the part.
