Important Prior Warnings
DANGER Keep out from under the pump when lifted.
Only qualified personnel shall unload and lift the pump.
Keep pump at horizontal position when lifted.
Do not lift the pump without eyebolt spacer.
WARNING Be careful not to overturn the pump when pushing and pulling it
sideways, because the pump is narrow in comparison to its height.
WARNING Only a qualified electrician should perform electrical works,
observing all national and local electrical regulations.
WARNING Interrupt Earth Leakage Breaker (ELB) before starting on Cut and lock out power
before beginning wiring and or maintenance work.
Do not switch on the power supply to the pump until work is completed and pump
and piping are returned to safe operating condition.
WARNING Supply N2 gas to the exhaust piping when necessary to dilute the flammable or
toxic gas down to a safe concentration.
WARNING Purge with sufficient N2 gas before removing and cleaning 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 byproducts.
WARNING Pump oil may be contaminated with process byproducts. Treat it as a hazardous
waste. See Table 3.1 for oil quantities.

EBARA CORPORATION
WARNING Exhaust from pumps handling process gases should be connected to an
appropriate exhaust abatement system that is equipped with discharge quality
monitors to provide warnings and shut down the process gas flow if gas
concentrations exceed allowable limits.
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 EBARA’s consent or
approval.
WARNING The pump casing and exhaust piping become extremely hot during operation and
remain hot for some time after stopping.
B
e sure that pump and exhaust piping do not come in contact with humans or
inflammable substances.
Do not remove pump enclosure panels during operation
WARNING Check Safety Interlock functions periodically (every 6 months) to confirm correct
operation.
WARNING Disposal of process by-products shall be strictly in accordance with all local and
national environmental and safety regulations
WARNING Disposal of Printed circuit board containing lithium battery shall be strictly in
accordance with all applicable local and national environmental 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.
WARNING Do not perform a withstand voltage test.Failure to comply could
result in damage to the sensitive devices.
