For afe operation
CAUTION
U e at
de ignated
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 bodily injury such as
burns due to overheating.
Pa y at tenti on
to ventil at io n
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.
Do not block inlet and outlet of cooling air with
obstruction. (Separate inlet side of the cooling
air from obstruction or wall by 10cm or more,
and separate outlet side by 30cm or more)
Avoid du t
Danger of du t
Be sure site is free from dust.
Sucking in of dust can cause failure.
Fix o n a
olid le ve l
floor
Danger of movement
Be sure to fix on solid and level floor (less than
5° inclination).
Uneven fix can cause failure and movement of
vacuum pump. If fix floor is unstable, fix pump
with 4 bolts using hole of
φ
9mm at leg section.
Avoid di re ct
unlig ht
Danger of overheating
Install where equipment is not exposed
to direct sunlight.
Vacuum pump exposed to direct
sunlight can overheat, resulting in
failure.
Check voltage
Motor burnout
Before doing any wiring, check electric source
and voltage. This pump is multi voltage type of
AC100V/AC200V. Voltage can be changed at
terminal block. This pump is wired to 100V
when delivered to you. Check your electric
source, voltage, and wire correctly to terminal
block. Improper wiring and incorrect voltage can
cause motor burnout.
In pect cau e
of problem
Danger of problem recurrence
and failure
If protective device 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 cap
Danger of cap to fly
Remove cap from inlet and outlet. Operation
with cap being fitted can cause cap to fly by
intake of exhaust impetus, resulting in accident,
failure, or bodily injury from contact with flying
objects.
Prevent foreign
matter from
entering
Danger of foreign matter
entering inlet
When checking turning direction, be
careful not to enter foreign matter into
an inlet.
Foreign matter 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 bodily
injury such as burns due to overheating.
Pay attention to
exhau t
re i tance
Danger of exhau t di ruption
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.
Prevent foreign
matter from
entering
Danger of foreign matter entering inlet
If you use the seal material or the adhesive,
etc. to prevent Leak of the joint when piping
with internal screw of inlet, be careful not to
enter the seal material or the adhesive into an
inlet.
The seal material or the adhesive entering inlet
can cause failure.
