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 =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.
WARNING
Health hazard and risk of environmental damage from toxic contaminated operating fluid
Toxic process media can cause operating fluid contamination. When changing the operating fluid,
there is a health hazard due to contact with poisonous substances. Illegal disposal of toxic substan-
ces causes environmental damage.
► Wear suitable personal protective equipment when handling these media.
► Dispose of the operating fluid according to locally applicable regulations.
WARNING
Risk of cuts on moving, sharp-edged parts when reaching into the open high vacuum flange
With the high vacuum flange open, access to sharp-edged parts is possible. A manual rotation of the
rotor increases the danger situation. There is the risk of cuts, up to the separation of body parts (e.g.
fingertips). There is a risk of hair and loose clothing being drawn in. Objects falling in destroy the tur-
bopump during subsequent operation.
► Only remove the original protective covers immediately prior to connecting the high vacuum
flange.
► Do not reach into the high vacuum connection.
► Wear protective gloves during installation.
► Do not start the turbopump with open vacuum connections.
► Always carry out the mechanical installation before electrical connection.
► Prevent access to the high vacuum connection of the turbopump from the operator side (e.g.
open vacuum chamber).
CAUTION
Scalding from hot operating fluid
Danger of burns when draining operating fluid if it comes into contact with the skin.
► Wear protective equipment.
► Use a suitable collection receptacle.
