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.
+
Make sure that the exhaust pipeline cannot become
blocked.
+
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-
play flashes. Release pressure immediately! Risk of
bursting!
