CAUTION
Cutting injuries on sharp and rotating parts with the high vacuum flange open during installa
tion
With the high vacuum flange open, access to sharp-edged parts is possible. There is a risk of cutting
injuries. Objects falling inside destroy the pump during subsequent operation.
► Only remove the original protective cover immediately before connecting the high vacuum flange.
► Do not reach into the high vacuum flange.
► Wear protective gloves during the installation process.
► Do not put the pump into operation with the vacuum flanges open.
► Ensure that the mechanical installation is completed before the electrics are connected.
NOTICE
Danger of property damage due to an incorrect counter flange design
Unevennesses of the customers counter flange result in distortion in the pump housing even when
correctly affixed. The result is leaks or negative changes in the running properties.
► Observe the shape tolerances for the counter flange.
► Observe the maximum deviations in evenness across the entire surface.
Risks during operation
WARNING
Danger of death from poisoning due to toxic gases being expelled without an exhaust line
Exhaust gases and vapors are released from the turbo pumping station unhindered during normal us-
age. In the case of processes with toxic media, there is a risk of injury and danger of death due to
poisoning.
► Note the corresponding regulations for handling toxic substances.
► Toxic process gases should be safely conveyed away via an exhaust line.
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.
NOTICE
Leaks may occur due to the incorrect installation of CF flanges
Inadequate cleanliness when handling CF flanges and copper seals results in leaks and may cause
process damage.
► Always wear suitable gloves before touching or fitting any components.
► Fit seals only if dry and free of grease.
► Note any damaged surfaces and cutting edges.
► Replace the damaged components.
NOTICE
Destruction of the pump due to gases with excessively high molecule masses
When conveying gases with non-permissibly high molecule masses, there is a risk of the turbopump
being destroyed.
► Make sure the gas mode is set correctly
[P:027]
on the electronic drive unit.
► Consult Pfeiffer Vacuum before using gases with larger molecule gases (> 80).
