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.
• You must take suitable precautions to prevent any
dangerous situation from arising if the controller starts
a NT VARIO or VARIO-B pump, switches a coolant
valve or opens a venting valve.
• Attention: If the controller is set to Autostart, the pro-
cess will start immediately after a power failure with-
out pressing any further key. It is your responsibility to
ensure that automatic start-up of the system will not
lead to any dangerous condition. Provide appropriate
safety measures. Check prior to starting the process
whether the option ”Autostart” (menu: configuration) is
enabled.
