Safety Information
Anyone operating this pump must have the knowledge to identify and avoid hazardous
conditions associated with the pump.
Rash actions or improper operation may cause dangerous accidents and serious injuries.
Before installation and operation, the operator first should have a thorough knowledge of the
pump’s construction, operating procedures, and hazards.
The operator should read this instruction manual and other documents issued by EBARA.
If you have any questions on pump operation, safety, or maintenance, please do not hesitate
to contact EBARA directly.
Three terms in this manual designate different levels of hazard:
DANGER indicates an imminently hazardous situation that, if not avoided, will
result in death or serious injury.
WARNING indicates a potentially hazardous situation that, if not avoided, could
result in death or serious injury.
CAUTION indicates an imminently hazardous situation that, if not avoided, may
result in minor or moderate injury.
This term may also indicate situations that might damage
equipment.

(iii)
Important Precautions
DANGER Keep out from under the pump when it is elevated.
Only qualified personnel should unload and lift the pump.
WARNING Be careful not to overturn the pump when pushing or pulling it
sideways. The pump is narrow in comparison to its height.
WARNING Only a qualified electrician, observing all national and local
regulations, should perform electrical work.
WARNING Cut and lock out electrical power before beginning wiring or
maintenance work.
Do not switch on the power supply to the pump until work is
completed and pump and piping are back in safe operating
condition.
WARNING Supply N2gas to the exhaust piping when necessary to dilute
flammable or toxic gases down to a safe concentration.
WARNING Purge system with sufficient N2gas before removing and cleaning
the vacuum lines and exhaust piping.
Prevent dispersal of flammable, toxic or dangerous materials and
guard against their contact with the human body.
Work only in locations with an emergency escape route.
WARNING Do not convert the pump from one process to another without an
intervening overhaul. Gases or reaction products remaining in
the pump may react and lead to accidents or to the formation of
large amounts of byproduct.
WARNING Check Safety Interlock functions periodically (every 6 months) to
confirm correct operation. See Appendix 2 for a description of
these interlocks.
WARNING Connect exhaust from pumps handling process gases to an
appropriate exhaust abatement system that is equipped with
discharge quality monitors to provide warnings and to shut down
the process gas flow if concentrations exceed allowable limits.
WARNING Check for gas leaks after initial installation of the piping and after
reassembly following maintenance or, at least, annually. Gas
leaks can result in the discharge of harmful and dangerous
substances and in abnormal reactions due to the admission of air
into the pump. Replace o-rings as required to correct leaks.
See Appendix 4.
WARNING Do not modify the pump or any of its parts without EBARA's
approval.
EBARA Corporation
(iv)
WARNING Do not place the LCD controller on or near a surface with a
temperature exceeding 65ºC.
WARNING The pump casing and exhaust piping become extremely hot
during operation and remain hot for some time after stopping.
Keep pump and exhaust piping away from contact with personnel
and flammable substances.
Do not remove pump enclosure panels during operation.
CAUTION Disposal of process byproducts must be in strict accord with all
local and national environmental and safety regulations.
CAUTION Dispose of printed circuit boards containing lithium batteries in
strict accord with all applicable local and national environmental
regulations.
CAUTION The height of EBARA dry pumps may place the EMO button and
the LCD controller below the heights recommended in SEMI
S8-95. See Appendix 3.
The following safety warning labels appear on the pump covers:
High temperature warning
Hazardous voltage warning
Hazardous materials warning
Electric charge mark
Hazardous weight danger
