Risks during maintenance, decommissioning and disposal
WARNING
Danger to life from electric shock during maintenance and service work
The device is only completely de-energized when the mains plug has been disconnected and the tur-
bopump is at a standstill. There is a danger to life from electric shock when making contact with live
components.
► Before performing all work, switch off the main switch.
► Wait until the turbopump comes to a standstill (rotation speed f = 0).
► Remove the mains plug from the device.
► Secure the device against unintentional restarting.
WARNING
Danger of poisoning from toxic vapors
Igniting and heating synthetic operating fluid generates toxic vapors. Danger of poisoning if inhaled.
► Observe the application instructions and precautions.
► Do not allow tobacco products to come into contact with the operating fluid.
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
Risk of burns on hot surfaces when using additional equipment for heating during operation
The use of additional equipment for heating the vacuum pump or for optimizing the process gener-
ates very high temperatures on surfaces that can be touched. There is a risk of burning.
► If necessary, set up a contact guard.
► If necessary, apply the warning stickers provided for this at the danger points.
► Ensure adequate cooling down before working on the vacuum pump or in its vicinity.
► Wear protective equipment, e.g., gloves.
WARNING
Risk of cuts on moving, sharp-edged parts when reaching into the open high vacuum connec-
tion
Incorrect handling of the turbopump before maintenance work results in hazardous situations with
risk of injury. There is a risk of cuts from accessing sharp-edged, rotating parts when removing the
turbopump.
► Wait until the turbopump comes to a standstill (rotation speed f = 0).
► Switch the turbopump off properly.
► Secure the turbopump against re-start.
► Seal open connections immediately following removal, using the original protective cover.
