Always provide a free and pressureless exhaust outlet
to avoid damage to pump valves and risk of bursting.
+
Attention: Due to clogging of the silencer an internal
overpressure may build up, which may damage bear-
ings, diaphragms and valves. Preferably use the hose
nozzle as outlet and make sure that the exhaust pipe-
line cannot become blocked.
+
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.
