For safe operation
CAUTION
Use at
designated
temperature
Danger of overheating
Operate at ambient temperature of 5
℃
~40
℃
.
Operating at a temperature range other
than that designated can cause accident,
failure or injury such as burns due to
overheating.
Pa y att enti on
to v ent ilat ion
Install the unit in a well-ventilated area.
Poor ventilation can disrupt cooling and
cause accident, failure or injury such as
burns since this vacuum pump is an air-
cooled type.
Av oid d us t
Danger of dust
Be sure site is free from dust.
Sucking in of dust can cause failure.
In st all o n a

fl oor
Danger of unbalance
Be sure to install on solid and level floor
(less than 5° inclination).
Uneven installation can cause failure and
movement of vacuum pump. If installation
floor is unstable, fix pump base with 4-
φ11 holes of pump leg.
Av oid d ir ect
su nl igh t
Danger of overheating
Install the unit in a place where it is not
exposed to direct sunlight.
Vacuum pump is exposed to direct
sunlight can overheat, resulting in failure.
Check voltage
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/400V. Voltage
can be changed at terminal block. This
pump is wired to 200V when shipping
from factory. Check your electric source,
voltage, and cord correctly to terminal
block.
Improper wiring and incorrect voltage can
cause motor burnout.
Inspect cause of
problem
Danger of problem recurrence
and failure
If protective device or thermal protector activates,
be sure to turn off electric source and inspect
causes to solve the problem.
Do not operate until problem is solved.
Operation while problem is left unsolved can
cause problem recurrence and failure.
Remove blank
flange
Danger of exhaust disruption
Remove blank flange from inlet and outlet.
Operation with blank flange being fitted
can disrupt air flow or cause blank flange
to fly by exhaust impetus, resulting in
accident, failure, or injury from contact
with flying objects.
Prevent human
body from
contacting
Danger of human body parts
contacting vacuum
At starting up of the vacuum pump and
during operation, be careful not to enter
human body into the inlet.
You can cause injury to people and
damage to equipment.
Prevent foreign
objects from
entering
Danger of foreign objects entering
inlet
When checking turning direction, be
careful not to enter foreign objects into an
inlet.
Foreign objects entering inlet can cause
failure.
Check fan
Danger of overheating
Check that cooling fan is turning and
cooling air is flowing.
If not, it can cause accident, failure or
injury such as burns due to overheating.
Pay attention to
exhaust
resistance
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 resistance can disrupt air flow,
resulting in failure and over-current.
