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.
Pay a tten t i o n
to ventil a t i o 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 1cm
or more, and separate outlet side by10cm
or more)
Avo i d d u t
Danger of du t
Be sure site is free from dust.
Sucking in of dust can cause failure.
In tall o n a
olid, l e vel
floor
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 φ9
holes of pump leg (ISP 50).
Avo i d d irect
unlig h t
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.
ISP 50 SV1 is AC100V class.
Voltage can not be changed. Check your
electric source, voltage, and wire correctly
to receptacle.
Improper wiring and incorrect voltage can
cause motor burnout.
In pect cau e 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 exhau t di ruption
Remove blank flange from inlet and outlet.
Operation with blank flange being fitted
can disrupt exhaust or cause blank flange
to fly by 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 overcurrent.
Start or top
after clo ing
i olation valve
Danger of vacuum break and
pollution
Be sure to close isolation valve between
vacuum pump and vacuum system
(chamber) during startup 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.
