emergency, it can cause accident, fire or
failure.
Install
emergency stop
switch
Danger of accident, fire or failure
Be sure to install an electric source
emergency stop switch (or protective
device that can urgently stop).
If the equipment is not stopped in an
emergency, it can cause accident, fire or
failure.

shock can result.
If you have any questions about the
selection of protective devices, contact
either the dealer who sold it to you or us.
Be careful about
wiring
Danger of short-circuit and
electric shock
We recommend an electric source cable
of more than 2mm
2
(more than rated
10A/1-phase, 7A/3-phase) cross section
area for electric source cable and earth
cord.
Be careful to avoid voltage drop

For safe operation
WARNING
Protect cable
from being
pulled
Danger of short-circuit and
electric shock
The power-supply conductor shall be free
from strain including twisting by using cord
anchorage, which is specified by the local
electrical wiring regulation.
If not, it can cause short-circuit fire or
injury from electric shock.
Be sure to
ground
Danger of electric shock

motor terminal box.
If not, it can cause injury from electric
shock.
With a thermal
protector [Only
single-phase
motor]
Danger of restart

maintenance or inspection.
Single-phase motor has a thermal
protector.
Vacuum pump restarts become cool
without warning after vacuum pump.
.
Never evacuate
hazardous gas
Danger of explosion and ignition

to humans or explosive, flammable, or
corrosive. Do not evacuate any gas with
substances containing chemicals,
solvents, and powders.
If done, it can cause failure or injury by
gas, explosion or ignition.
Avoid foreign
objects
Danger of entanglement and
foreign objects dispersal
Never put finger or foreign objects into air
hole of fan cover, air hole of motor or
clearance between FS(1) and FS(2)
cooling fins.
If done, it can cause injury from
entanglement with turning section, or
foreign objects dispersal.
Never make any
modifications
Danger of electric shock and
entanglement
Do not remove or modify safeguards or
insulation parts.
If done, it can cause injury from electric
shock or turning section and it can cause
deteriorated performance and operating
lifetime, and invalidate guarantee.
Change after
vacuum pump is
stopped
Danger of failure and injury
Change air-flush port only after vacuum
pump is stopped.
If you change it during vacuum pump
operation, it can cause vacuum pump
failure and injury.
Conduct
periodical
maintenance and
inspection
Danger of failure and injury
Conduct periodical maintenance and
inspection.
If not, it can cause insufficient
performance, failure of vacuum pump, and
injury.
Be careful about
high temperature
Danger of burns
Conduct maintenance and inspection only
after vacuum pump becomes cool enough.
Maintenance and inspection soon after
vacuum pump stops can cause burn
injury.
Turn off electric
source
Danger of electric shock
Be sure to conduct maintenance and
inspection after you turn off electric
source.
If not, it can cause injury from electric
shock or turning object.
Ask specialist to
perform repairs
Danger of accident, failure and
shorter operating lifetime
Ask specialist to perform repairs.
Defective repairs can cause accident,
failure or shorter operating lifetime.

-4-
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.
P a y a tt e nt io n
t o ve n ti l at io n
Danger of overheating
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.
A v oi d d u s t
Danger of dust
Be sure site is free from dust.
Sucking in of dust can cause failure.
I n st a ll o n a
s ol id , l e v el
fl oo r
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-11
holes of pump leg.
A v oi d d i r e ct
su nl i gh 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.

For safe operation
CAUTION
O pe n a i r
in le t
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.
Start or stop
after closing
isolation valve
Danger of vacuum break and
pollution
Be sure to close isolation valve between
vacuum pump and vacuum system
(chamber) during start-up and stop.
Start-up or stop with isolation valve in the
open position can draw back gas and
debris attached to inside of pump to
vacuum chamber due to pressure
differential, resulting in vacuum break and
pollution on vacuum chamber side.
B ew a r e
te mp era t ur e
of i nt ake ga s
Danger of exceeding permissible
temperature of intake gas
If intake gas temperature is over 50
℃
, be
sure to install a chiller or trap
between vacuum pump and vacuum
chamber so that gas intake temperature of
vacuum pump keeps below 50
℃
.
If not, vacuum pump temperature can
increase, resulting in failure.
Operate the unit
while opening
air-flush port
Danger of remaining moisture
When evacuating moisture, be sure to
open air-flush port (air-flush operation).
If you evacuate vapor while air-flush port
is closed, condensed water will remain
inside vacuum pump and cause failure.
Caution after
exhausting vapor
Danger of insufficient vapor
exhaust
After evacuating vapor, do air-flush
operation for at least one hour.
If you close air-flush port or stop vacuum
pump soon after evacuating vapor,
condensed water will remain inside
vacuum pump which will cause failure.
Beware of intake
gas volume
Danger of exceeding permissible
intake gas volume
When sending N
2
gas or dry air into
air-flush port, pressure should be the
same as atmospheric pressure and flow
rate should be less than 10L/min.
If not, it can increase pressure inside
vacuum pump, resulting in failure.
Caution for
frequent
start/stop and
short interval
Risk of motor malfunction
Refrain from frequent start/stop operation.
It induces malfunction of motor such as
burn out.
Please consult your dealer or factory
representative for details.
Appropriate operating mode with
adequate interval and frequency of
start/stop is varies owing to operating
condition.
