It is our responsibility, as people of the earth, to protect nature's irreplaceable treasures
and to pass them on to future generations.
As we undertake our business activities, we will establish environmental management
systems and implement ongoing improvements and reviews, while striving to promote
harmony between technology and nature, prevent environmental pollution, and improve
the overall results of our environmental management activities. We are aware that
environmental protection and management activities are the responsibility of all managers
and employees of the Corporation, and each person will demonstrate this awareness
when carrying out his or her duties.
We will widely publicize these basic policies to regional societies and the general public
and work to make Ebara's position on the environment clear to society in general.

（ii）
Safety Information
It is essential that those operating this pump should have the knowledge to identify and avoid
hazardous conditions associated with the pump.
Inadequate or rash operation may cause dangerous and serious accidents.
Before installation and operation, the operator should first have a good knowledge of the pump
construction, operation procedure, and its hazards.
The operator should read through this instruction manual and other documents issued by
EBARA in detail.
If you have any questions on pump operation, safety, and maintenance, please do not hesitate
to contact EBARA directly. Refer to Global network for contact address.
Three terms designating the level of hazard are used in this manual.
DANGER indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.
WARNING
indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
CAUTION indicates an imminently hazardous situation which, if not
avoided, may result in minor or moderate injury.
This term may also be used as a warning for situations liable to
damage to equipment.
[ NOTE ] The notes for the safe and proper handling of the product.
PM10U EBARA CORPORATION

（iii）
Important Prior Warnings
DANGER Keep out from under the pump when lifted.
Only qualified personnel shall unload and lift the pump.
WARNING Be careful not to overturn the pump when pushing and pulling it
sideways, because the width of the pump is small to its height.
WARNING All electrical works must be performed by only a qualified electrician.
All national and local electrical regulations must be observed.
WARNING Circuit Breaker (CB) is not installed in the pump unit.
Please install Circuit Breaker (CB) based on the law and the standard
in the installation region.
WARNING Interrupt Circuit Protector (CP) before starting on wiring
and maintenance work.
Do not switch on the power supply to the pump until work is completed.
WARNING Supply N2gas to the exhaust piping when necessary to dilute
the inflammable or toxic gas up to a safe concentration.
WARNING Purge with sufficient N2gas before removing and washing the
vacuum and exhaust piping.
Do not let inflammable, toxic or dangerous materials
disperse and guard against contact with the human body.
Always work in a location with an escape route in an emergency.
WARNING Do not use the pump for another process without a previous
overhaul. Gases or reaction products remaining in the pump will
react and lead to accidents with the formation of large amounts of
products.
PM10U EBARA CORPORATION

（iv）
WARNING Check for gas leaks after installing and maintaining the piping.
Gas leaks will result in the discharge of harmful and dangerous
substances and in abnormal reactions due to the ingress of air
into the pump. When checking for gas leaks by pressurization,
please pressurize by less than 0.05 MPa into the purge port and
do check.
WARNING Do not alter the pump member nor change any parts without the
EBARA's consent or approval.
WARNING The pump casing and exhaust piping become extremely hot
during operation and for some time after stopping.
Be sure that pump and exhaust piping do not come in contact
with humans or inflammable substances.
Do not remove the pump cover during operation.
WARNING Check Safety Interlock functions periodically (every 6 months) to
confirm the interlocks will work correctly.
CAUTION Disposal of process by-products shall be strictly in accordance
with all local and national environmental and safety regulations.
CAUTION Disposal of Printed circuit board containing Lithium battery shall
be strictly in accordance with all local and national environmental
and applicable regulations.
WARNING In designing the dry pumps, Ebara does not assume risks
caused by hazardous chemical reactions resulted from
simultaneous injection or mixture of multiple process gases in
the pumps, and the pump is not equipped with a protection
against the dangers from such pump usage. The tool suppliers
and users must pay attention not to simultaneously inject or mix
those gases.
PM10U EBARA CORPORATION

（v）
WARNING Do not perform a withstand voltage test.
Failure to comply could result in damage to the sensitive devices.
WARNING In MODEL EV-S20 type pump, the bolt which is fixing the lifting
bracket to a pump is M6✕12. This lifting bracket can use as fixing
bracket. When you use this bracket as fixing bracket, you use M6✕
16 bolts for fixing this bracket to the lower side of the pump. When
you use this bracket as lifting bracket, you cannot use the M6✕16
bolts, because the M6✕16 bolts reach to an internal part and have a
possibility to break it.
・Using this bracket as a lifting bracket, please use the bolt of
M6✕12(hexagon head bolts).
・Using this bracket as a fixing bracket, please use the bolt of
M6✕16(hexagon head bolts).
CAUTION Never operate the pump without pump cover for safety.

Safety Interlocks
WARNING Check Safety Interlock functions periodically (every 6 months)
to confirm the interlocks will work correctly.
NITROGEN FLOW LOW
A normally open flow switch breaks when nitrogen supply to the pump (oil
bearing(s) and inter stage injection) drops below its factory set point, opening the
motor starter relay(s) and shutting down the pump. Restoration of sufficient
nitrogen flow permits restarting the pump.
MOTOR OVERLOAD
Motor thermostat protect the pump motor from overheating due to extended current
draws in excess of the motor rating. Under a persistent overload condition, motor
thermostat opens a contact, which interrupts the motor run circuit. A brief cool
down interval permits restarting the pump.
