Risks during operation
WARNING
Risk of injury resulting from overpressure in the vacuum system
Opening tensioning pieces with an overpressure > 1000 hPa in the vacuum system can lead to inju-
ries as a result of flying parts, and escaping process medium could prove harmful to health.
Elastomer seals in KF connections (e.g. O-rings) are not resistant to pressures > 2500 hPa. This
could prove harmful to health due to escaping process medium.
►Do not open any tensioning pieces when overpressure is prevalent in the vacuum system.
►Use suitable tensioning pieces for overpressure.
►Use tensioning pieces which can only be opened and closed using a tool (e.g. tightening strap-
circlip).
►Use sealing rings with an outer centering ring.
Risks during maintenance
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.

WARNING
Health hazards due to cleaning agent
The cleaning agent being used causes health hazards which could include, for example, poisoning,
allergies, skin irritations, chemical burns or damage to the airways.
►When handling cleaning agents, observe the applicable regulations.
►Adhere to safety measures regarding handling and disposal of cleaning agents.
►Be aware of potential reactions with product materials.
Risks when shipping
WARNING
Risk of poisoning from contaminated products
Where products that contain harmful substances are shipped for maintenance or repair purposes, the
health and safety of service personnel is at risk.
►Comply with the instructions for safe distribution.
