CAUTION
Danger of overheating
Install in a well-ventilated area. Poor ventilation
can disrupt cooling and cause accident, failure or
bodily injury such as burns since this vacuum
pump is an air-cooled type.

Danger of unbalance
Be sure to install on solid and level floor (less than
5° inclination).

Motor burnout
Before doing any wiring, check electric source and
voltage. Single-phase is a multi voltage type of
AC100V/AC200V. Three-phase is a multi voltage
type of AC200V/AC400V. Voltage can be changed
at terminal block. This pump is wired to 200V
when delivered to you. Check your electric source,

Improper wiring and incorrect voltage can cause
motor burnout.
Danger of exhaust disruption
Remove blank flange from inlet and outlet.
Operation with blank flange being fitted can disrupt
exhaust or cause blank flange to fly by exhaust
impetus, resulting in accident, failure, or bodily
injury from contact with flying objects.

Danger of exhaust disruption
When connecting exhaust piping to vacuum pump
and when combining piping with another vacuum
pump, pay attention to piping size and length so
that it does not cause exhaust resistance. Exhaust

Danger of abnormal sound and failure
Open inlet to atmosphere for about 5 seconds
before restarting vacuum pump.
If not, it can unbalance temperature inside vacuum
pump, resulting in failure.
