Risks during operation
WARNING
Danger of poisoning due to emission of toxic process gases from the exhaust
During operation with no exhaust line, the vacuum pump allows exhaust gases and vapors to escape
freely into the air. In processes involving toxic media, there is a risk of injury and danger to life due to
poisoning.
► Observe the relevant regulations for handling toxic substances.
► Safely purge toxic process gases via an exhaust line.
► Use suitable filter equipment to separate toxic substances.
WARNING
Risk of injury from reactive, explosive or other hazardous gas/air mixtures
Uncontrolled gas inlet of air or gases containing oxygen promotes formation of unexpected explosive
gas/air mixtures in the vacuum system. This results in severe injuries.
► Use only inert gases for supplying the sealing gas supply in order to avoid a potential ignition.
WARNING
Risk of crushing on rotating parts when reaching into the open flange
The pistons continue to run in the vacuum after switching off the motor, and can trap fingers and
hands within their reach.
► Wait until the vacuum pump comes to a complete standstill.
► Secure the vacuum pump against re-start.
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.
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.
Risks during maintenance, decommissioning and malfunctions
WARNING
Health hazard through poisoning from toxic contaminated components or devices
Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.
► Take suitable safety precautions and prevent health hazards or environmental pollution by toxic
process media.
► Decontaminate affected parts before carrying out maintenance work.
► Wear protective equipment.
