Safety during operation

Adopt suitable measures to prevent the release of dan-

gerous, toxic, explosive, corrosive, noxious or pollut-

ing fluids, vapors and gases. To prevent any emission

of such substances from the pump outlet, install an

appropriate collecting and disposal system and take

protective action for pump and environment.

You must take suitable precautions to prevent any for-

mation of explosive mixtures in the pump chamber or

at the outlet of the pump. In case, e.g., of a diaphragm

failure, mechanically generated sparks, hot surfaces

or static electricity may ignite these mixtures. Use inert

gas for gas ballast or venting, if necessary.

Drain appropriately or otherwise remove any poten-

tially explosive mixtures at the outlet of the pump, or

dilute them to non-explosive concentrations.

Never operate this pump if it has a damaged cord or

plug.

If the pump is not working properly, has been dropped

or has fallen into water, contact your pump service pro-

vider.

Prevent any part of the human body from coming into

contact with vacuum.

If there is an exhaust isolation valve, make sure that you

cannot operate the equipment with the valve closed to

avoid a

risk of bursting!

Always provide a free and pressureless exhaust outlet

to avoid damage to pump valves and risk of bursting.

Check the overpressure safety relief device at the ex-

haust waste vapor condenser at appropriate intervals.

Attention: At pressures above approximately 795 Torr

(1060 mbar) the pressure reading becomes incorrect

due to saturation of the pressure transducer. The dis-
