Environmental Basic Policies

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.

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 others documents issued by

EBARA in detail.

If you have any questions on pump operation, safeties, 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.

PM10U EBARA CORPORATION

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 Turn power off and lockout before starting on wiring

and maintenance work.

Do not switch on the power supply to the pump until work is

completed.

WARNING Supply N2 gas to the exhaust piping when necessary to dilute

the inflammable or toxic gas up to a safe concentration.

WARNING Purge with sufficient N2 gas 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.

（iv）

PM10U EBARA CORPORATION

WARNING To avoid any hazard induced by toxicity, flammability and

explosiveness of the process gases used in the tool, be sure to

operate the tool according to the operations safety guidelines

supplied by tool suppliers.

Appendix 6 lists typical process gases used in a

semiconductor-processing tool. However, details concerning

the tool gases and other concerns specific to your tool should

be directed to the respective tool suppliers.

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.

（v）

PM10U EBARA CORPORATION

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.

WARNING Do not perform a withstand voltage test.

Failure to comply could result in damage to the sensitive

devices.

CAUTION Never operate the pump without pump cover for safety.

CAUTION This pump might break down if the voltage setting is not

correctly changed. The default voltage setting is indicated on

the pump cover with label. Please indicate the new voltage

setting on the pump, when the voltage setting was changed.
