CAUTION
Risk of injury from bursting due to high pressure in the exhaust line
Faulty or insufficient exhaust lines cause hazardous situations, e.g. increase in exhaust pressure.
There is a risk of bursting. It is not possible to rule out the risk of injuries due to broken pieces flying
around, high escaping pressure and damage to the equipment.
► Lay the exhaust line without shut-off units.
► Observe the permissible pressures and pressure differentials of the product.
► Check the exhaust line regularly for correct function.
Risks during maintenance
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 =0).
► Remove the mains plug from the device.
► Secure the device against unintentional restarting.
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.
Risks during disposal

Risks in the event of malfunctions
WARNING
Danger to life from the turbopump breaking away in the event of a fault
Sudden blocking of the rotor generates high destructive torques in accordance with ISO 27892. If the
turbopump is
not
properly secured, it will tear off. The energy released in this way can propel the en-
tire turbopump or shattered pieces from its interior through the surrounding area. Potentially danger-
ous gases may escape. There is a risk of serious injury, potentially even fatal, and significant equip-
ment 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.
