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 bodily injury such as burns due
to overheating.
Pa y atten tion
to ventila tion
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.
Avoid du st
Danger of dust
Be sure site is free from dust.
Sucking in of dust can cause failure.
Install o n a
solid, le ve l
floor
Danger of unbalance
Be sure to fix vacuum pump on solid and level
floor (less than 5° inclination).
Uneven fix can cause failure and movement of
vacuum pump. Fix pump base with 4 bolts using
hole of
φ
9mm at bracket.
Avoid d irect
sunlight
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 a multi voltage type of
AC100V/AC200V. Voltage can be changed at
terminal block. This pump is wired to 100V 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 cap
Danger of cap to fly
Remove cap from inlet and outlet.
Operation with cap being fitted can cause cap to
fly by intake or exhaust impetus, resulting in
accident, failure, or bodily 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
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
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.
