CAUTION
D tach
packaging tray
Dang r of abnormal vibration
Detach equipment from packaging tray.
Operation while equipment is mounte on
packaging tray can cause abnormal
vibration, resulting in acci ent an failure.

t mp ratur
Dang r of ov rh ating
Operate at ambient temperature of 10
℃~
40
℃
.
Operating at a temperature range other than that
esignate can cause acci ent, failure or bo ily
injury such as burns ue to overheating.
Pay a tt ntion
to v nt i lati o n
Dang r of ov rh ating
Install in a well-ventilate area. Poor
ventilation can isrupt cooling an cause
acci ent, failure or bo ily injury such as
burns since this vacuum pump is an
air-coole type.
Avoi d d u s t
Dang r of dust
Be sure site is free from ust.
Sucking in of ust can cause failure.
Insta l l on a
soli d , l v l
floor
Dang r of unbalanc
Be sure to install on soli an level floor
(less than 5° inclination).
Uneven installation can cause failure an
movement of vacuum pump. If installation
floor is unstable, fix pump base with 4
bolts using M10 tap section.
Avoi d d i r ct
sunl i g h t
Dang r of ov rh ating
Install where equipment is not expose to irect
sunlight.
Vacuum pump expose to irect sunlight can
overheat, resulting in failure.
Ch ck voltag
Motor burnout
Before oing any wiring, check electric
source an voltage. This pump is a multi
voltage type of AC200V/AC400V. Voltage
can be change at terminal block. This
pump is wire to 200V when elivere to
you. Check your electric source, voltage,
an wire correctly to terminal block.
Improper wiring an incorrect voltage can
cause motor burnout.
Insp ct caus
of probl m
Dang r of probl m r curr nc and
failur
If protective evice or thermal protector activates,
be sure to turn off electric source an inspect
causes to solve the problem. Do not operate until
problem is solve . Operation while problem is left
unsolve can cause problem recurrence an
failure.
R mov blank
flang
Dang r of xhaust disruption
Remove blank flange from inlet an outlet.
Operation with blank flange being fitte
can isrupt exhaust or cause blank flange
to fly by exhaust impetus, resulting in
acci ent, failure, or bo ily injury from
contact with flying objects.

Dang r of for ign matt r nt ring inl t
When checking turning irection, be careful not to
enter foreign matter into an inlet. Foreign matter
entering inlet can cause failure.
Pay att ntion to
xhaust
r sistanc
Dang r of xhaust disruption
When connecting exhaust piping to
vacuum pump an when combining piping
with another vacuum pump, pay attention
to piping size an length so that it oes not
cause exhaust resistance. Exhaust
resistance can isrupt air flow, resulting in
failure an over-current.
Start or stop
aft r closing
isolation valv
Dang r of vacuum br ak and pollution
Be sure to close isolation valve between vacuum
pump an vacuum system (chamber) uring
start-up an stop. Start-up or stop with isolation
valve in the open position can raw back gas an
ebris attache to insi e of pump to vacuum
chamber ue to pressure ifferential, resulting in
vacuum break an pollution on vacuum chamber
si e.
