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
dangerous situation from arising if the controller starts
a vacuum pump (in combination with a VMS Module),
switches an in-line valve or 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.
•
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.
• Ensure that the
coolant outlet pipe
at the waste vapor
condenser is always free and that it cannot get blocked.
Prevent the backpressure of gases and the backflow of
condensates at the outlet.
