Be sure to wear safety equipment when using the product
Be sure to wear safety equipment (protective glasses, mask, etc.) compatible
with dangerous/hazardous materials before operating the product.
If safety equipment is insufficient or deficient, it is very dangerous when the
solution or oil flies off, injury may occur from the protruding portion or
inflammable gas is generated.
Caution
-1-
Use extreme caution when using inflammable and
combustible solution.
If inflammable and flammable solution (methanol) is allowed to stand at higher
(or lower depending on the solution) than the room temperature, it gasifies and
may lead to catching fire or burning due to a certain source of ignition.
Be sure to ventilate the room and pay careful attention in use.
Warning
Pay attention to the number of aluminum blocks set.
Set up required number of aluminum block on each unit before operation.
Without the block, temperature distribution may be worsened or the unit may
have bad effect.
Caution
Do not touch aluminum block or block handle
during operation and for a while after operation.
When preset temperature is high, aluminum block, block handle and also
around these parts are subject to have high temperature during operation and
for a while after operation. Take care not to burn yourself.
If carrying about aluminum blocks, check that they are cooled down and
lift the block handle.
Caution

This product is a dry and clean thermostat
without using water or oil and is suitable for
condensing a hydrophobic sample such as
moisture.
2-1 Usage
Do not remodel the product.
Make sure that it should not
