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!
+
Comply with applicable regulations when disposing of
chemicals. Take into consideration that chemicals may
be contaminated. Take adequate precautions to pro-
tect people from the effects of dangerous substances
(chemicals, thermal decomposition products of fluoro-
elastomers). Use appropriate protective clothing and
safety goggles.
+
Interruption of the pump (e.g., due to power failure),
failure of connected components or of parts of the sup-
ply, or change in parameters must not be allowed to
lead to dangerous conditions. In case of a diaphragm
failure or in case of a leak in the manifold, pumped
substances might be released into the environment or
into the pump housing or motor.
Comply with all notes regarding proper use of the
pumps, as well as operation and maintenance guid-
ance.
+
The residual leak rate of the equipment might render
possible an exchange of gas, albeit extremely slight,
between the environment and the vacuum system.
Adopt suitable measures to prevent contamination of
the pumped substances or the environment.
• Ensure that no parts of your clothing, hair or fingers
can be caught or drawn in at the inlet of the pump.
Never insert fingers or drop any other object into the
inlet or outlet.
