This product is designed to control a vacuum level of
a decompression condensation unit by controlling a
diaphragm type vacuum pump.
This product has a communication function and can
operate interlocked with different units by
connecting to a rotary evaporator, a water bath, a
diaphragm vacuum pump or a coolant circulation
unit equipped with a communication terminal with a
communication cable.
* A communication cable and other parts used
for connection are sold separately.
※
Note that this product is for gas only. Do not
flow liquid or solid through the product.
※
Control solenoids and pressure sensors are
consumable parts.
The pressure sensor is contained in the main
body and requires adjustment work for its
replacement. Ask your dealer or the nearest
service center for replacement.

Product overview
1 For safe operation
Take extreme care for safety because this product is not of the explosion-
proof structure.
WARNING
Never install in a dangerous atmosphere.
This product is not explosion-proof.
Using this product in a dangerous atmosphere may result in a fire.
CAUTION
Follow the instructions to connect pipes.
Wrong connection of pipes may prevent correct operation of the unit as well
as a malfunction or an unexpected accident.
Never attempt to modify the product.
Operate the unit for the specified
purpose only.
An electric shock or a malfunction may result if the
product is modified or used for any purposes other
than that specified.
Warning
* Although the product employs anti-corrosion parts,
it does not support all types of solvents.
The control solenoid or the pressure sensor may
deteriorate depending on the solvent used or
operating conditions and control of the product
might become impossible.
When such situation may occur, a solvent collector
such as a cooling trap will be necessary between
the decompression container and the vacuum
controller.
