Attention
: At pressures above approximately 810 Torr
(1080 mbar) the pressure reading becomes incorrect.
The display flashes and a warning message is dis

Comply with applicable regulations when disposing of
chemicals. Take into consideration that chemicals may
be contaminated.
Take adequate precautions to protect people from the
effects of dangerous substances (chemicals, thermal
decomposition products of fluoroelastomers). Use ap
-
propriate 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.
