In case of a leak in the manifold or at the shaft seal of
the rotary vane pump, or in case of a diaphragm crack
of the diaphragm pump, pumped substances might be
released into the environment or into the pump hous-
ing or motor.
Especially comply with notes on use and operation and
maintenance.

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.
• Check oil level of the rotary vane pump (through sight
glass) every time before starting the pump.
• Check the pump’s oil level and the condition of the oil
on a regular basis.
• 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.
• A power failure or switching off the pump may cause
accidental ventilation of the pump or the vacuum sys-
tem, if the manual gas ballast valve of the rotary vane
