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.
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 poisoning from contact with harmful substances
The operating fluid reservoir and parts of the turbopump may contain toxic substances from pumped
media.
► Decontaminate affected parts before carrying out maintenance work.
► Prevent health hazards or environmental impacts with adequate safety precautions.
► Observe the operating fluid safety data sheet.
► Dispose of the operating fluid reservoir according to applicable regulations.
Risks in the event of malfunctions
WARNING
Danger to life from the turbopump breaking away in the event of a fault
Sudden jamming of the rotor generates high destructive torques in accordance with ISO 27892. If the
turbopump is not properly secured, it can shear off. The energy that this would release could throw
the entire turbopump or shattered pieces from its interior through the surrounding space. Potentially
dangerous gases can escape. There is a risk of very serious injuries, including death, and extensive
property damage.
► Follow the installation instructions for this turbopump.
► Observe the requirements regarding stability and design of the counter flange.
► Use only original accessories or fixing material approved by Pfeiffer Vacuum for the installation.
WARNING
Risk of injury caused by the turbopump breaking away with the vibration compensator in the
event of a malfunction
Sudden jamming of the rotor generates high destructive torques in accordance with ISO 27892.
When using a vibration compensator, this will probably lead to the turbopump being sheared off in
use. The energy that this would release could throw the entire turbopump or shattered pieces from its
interior through the surrounding space. Potentially dangerous gases can escape. There is a risk of
very serious injuries, including death, and extensive property damage.
► Take suitable safety precautions on-site for the compensation of the occurring torques.
► Before installing a vibration compensator, you must first of all contact Pfeiffer Vacuum.
