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.
• Pumping at high inlet pressure may lead to overpres-
sure at the gas ballast valve. Pumped gases or con-
densate might be expelled if the valve is open. If an in-
ert gas supply is connected to the gas ballast, ensure
that its inlet pipeline is not contaminated.
• You must take suitable precautions to prevent any dan-
gerous situation from arising if the pump is starting.
• Pay attention to the safety symbol ”hot surfaces” on
the equipment. Hot parts may cause burns if touched.
Adopt suitable measures to prevent any danger aris-
ing from hot surfaces or electric sparks. Ensure that
hot surfaces of the pump do not cause burns. Provide
a suitable contact guard if necessary.
Prevent the backpressure of gases and the backflow of
condensates at the outlet.
Provide appropriate protective measures to allow for the
possibility of failure and malfunction. The protective mea-
sures must also allow for the requirements of the respec-
tive application.
