Risks during installation
DANGER
Danger to life from electric shock
Touching exposed and voltage-bearing elements causes an electric shock. Improper connection of
the mains supply leads to the risk of touchable live housing parts. There is a risk to life.
► Before the installation, check that the connection leads are voltage-free.
► Make sure that electrical installations are only carried out by qualified electricians.
► Provide adequate grounding for the device.
► After connection work, carry out an earthed conductor check.
WARNING
Danger of injury due to exposed rotating parts
Danger of crushing fingers and hands when the vacuum connection is open.
► Safely disconnect motor from the mains.
► Secure the motor against reactivation.
► Never insert hands or fingers into the vacuum connection.
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.
► Open shut-off units immediately before or at the same time as starting the pump.
► Take care that atmospheric pressure is always present on the exhaust side. Overpressure or un-
derpressure are not permissible.
► Check the function of the exhaust line on a regular basis.
Risks during operation
CAUTION
Health hazard from increased noise emission
Remaining in the close proximity of the vacuum pump for a sustained period of time may cause hear-
ing damage.
► Ensure adequate sound insulation.
► Wear hearing protection.
CAUTION
Danger of burns on hot surfaces
Depending on the operating and ambient conditions, the surface temperature of the vacuum pump
can increase to above 70 °C.
► Provide suitable touch protection.
