CAUTION
Danger of injury due to the pumping station tipping or rolling away
Superstructural parts change the center of gravity. There is a danger of crushing due to rolling away
or tipping.
► Place the pumping station on a flat installation surface.
► Anchor the pumping station at the installation location.
► Wear personal protective equipment.
CAUTION
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
► Route the exhaust line without shut-off units.
► Observe the permissible pressures and pressure differentials for the product.
► Check the function of the exhaust line on a regular basis.
Risks during operation
WARNING
Danger of death from poisoning due to toxic gases being expelled without an exhaust line
Exhaust gases and vapors are released from the turbo pumping station unhindered during normal us-
age. In the case of processes with toxic media, there is a risk of injury and danger of death due to
poisoning.
► Note the corresponding regulations for handling toxic substances.
► Toxic process gases should be safely conveyed away via an exhaust line.
WARNING
Risk of poisoning from incorrect use of the gas ballast system
The gas ballast system of the scroll pump is vacuum sealed only when used in valid, snapped posi-
tions "0", "1" and "2". When operating the valves in intermediate stages, there is a risk that process
media can escape to the environment uncontrolled. When using toxic process media, there is a risk
of poisoning.
► Change the positions of the valve only for setting the gas ballast stages.
► Operate the gas ballast valve only in the snap positions.
CAUTION
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
► Route the exhaust line without shut-off units.
► Observe the permissible pressures and pressure differentials for the product.
► Check the function of the exhaust line on a regular basis.
CAUTION
Risk of injuries due to contact with vacuum when venting
While venting the vacuum pump there is a risk of minor injuries due to the direct contact of body parts
with the vacuum, e.g. hematomas.
► Do not fully unscrew the venting screw out of the housing during venting.
► Keep a distance from automatic venting device, such as venting valves.
