It detects excess current or electric leakage
and turns off to shut down the power. Electric leakage or excess
current.
Mains switch
It detects over heating of heater, and shuts
down the power. Heater temperature is too high
because of low volume of drying
air.

5-2 Operation
Caution Caution
While operating unit,
do not touch heated parts.
While operating unit, and after operating,
the evaporating tube and cyclone are very
hot. Do not touch them to prevent burning
of your hands.
When some troubles occur,
stop operating immediately.
When some troubles occur, turn off mains
switch immediately, and check the unit
referring to the chapter [Trouble shooting].
This unit equips a magnetic stirrer, so magnetic
vessel or magnetic materials cannot be used.
Sample vessel
Distilled water
1. Preparing sample and distilled water
Put sample vessel which is filled with
sample solution on the stirring plate,
then put a supplied stirring bar into the
solution.
Prepare 200ml of distilled water with a
vessel.
* Use distilled water initially for one side
of tubing to control outlet temperature,
and then flow sample solution after the
temperature is stable.
2. Turning on power
First turn on the breaker of switch board,
the breaker of main unit, and last the
power switch.
Indications illuminate.
3. Setting inlet temperature
(1) Press SET key to illuminate set value
indication lamp, and set inlet temperature
by UP or DOWN key.
Setting range is 4 ~ 200°C.
(2) Press SET key again.
The measured value indication lamp illuminates
and inlet temperature can be checked.
