This product is subject to have high temperature.
Use extreme care when handling the product.
For your safety use
1
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

3-3 Constant-value operation, timer mode, step program
This product enables a step program to control the maximum eight set temperatures, including continuous operation in
constant-value operation, auto start and auto stop combining timer mode, in turn.
Constant-value operation
Raises the temperature to the set temperature "T,"
and after the set temperature "T" is reached continuously
operates until operation is stopped.
Timer mode
The use of the timer mode allows operation start
at an optional time or operation
stop at an optional time.
1.Auto start mode
After operation starts, the time count alone starts
and after elapse of a set time "t," the temperature starts
to raise to the set temperature "T" in constant-value operation or
step program.
After the set temperature "T" is reached,
constant-value operation is run and in the case of
the step program, stepwise operation is run.

Use only designated aluminum
blocks.
Use of an aluminum block other than those
designated may worsen temperature control
or temperature distribution and may cause
unexpected accidents.
Caution
-11-
Pay attention to the number of
aluminum blocks
Be sure to set the maximum number of
aluminum blocks for each device before
operation. It may cause degradation of and
temperature distribution or abnormal heat of
the heater.
Caution
* If you use a container other than glass, please check
the temperature limit before use.
Depending on the temperature in use, the container may
dissolve.
* When changing aluminum blocks, do not place high
temperature aluminum block on the top surface of the
device. The device may go out of order.
(2) Check that the heating plate and bottom surface of
aluminum blocks are free of deformation or attachment of
trash, stains, etc.
* Deformation of the heating plate or attachment of trash,
stains, etc. may worsen temperature precision or
temperature distribution.
(3) Gently place the required number of blocks.
The block handle of a regular block should be placed
inside the block.
The block handle of a half block should be caracoled
and placed on the top surface of the device.
(4) Check that the power switch is OFF and insert the
power plug into the outlet.
Be careful about the temperature
when replacing aluminum blocks
Check that the aluminum blocks and block
handle are cooled down before working on
them. Touch at high temperatures may lead to
burn.
Caution
(1) Prepare aluminum blocks suitable for the container to
be used.
See the right table for the types and required number of
aluminum blocks.
See "Option" on page 37 for types of blocks.

Model MGBH: 2 Model MGB: 1
Be fully careful about the use of
inflammable and flammable solutions
An inflammable, flammable solution (methanol
etc.) turns into gas if allowed to stand at more
than the room temperature (or below it
depending on a solution), potentially leading to
catching fire or burning with a certain source of
ignition.
For use, be sure to ventilate the room
and exercise full cautions.
Caution
A liquid spilt over the heating
plate or top surface of the device
should be wiped off promptly.
Water or a solution spilt over the top surface
of the device or the heating plate should be
wiped off promptly.
If it is left to stand, the heating plate may get
corroded or infiltration into the device may
lead to an accident such as electric leakage.
