5 Maintenance
We recommend an exchange of the rotor unit after 80,000 operating hours at
the latest.
Such maintenance work can only be done by the Leybold Service. If required
contact the Leybold service center nearest to your location. You can find the
address on our internet page www.leybold.com.
At high pump loads - for example during cyclic opera tion, at high gas
through puts or at high ambient temperatures - the aforementioned mainte-
nance work should be carried forward. Please consult Leybold for recom-
mendations.
Observe Safety information 0.1.7.
Depending on the degree of contamination of the purge gas used the filter
will clog and will have to be ex changed (our experience indicates that this will
become necessary after 1 to 6 months).
When an adsorption trap is used, regenerate or renew the adsorption agent
regularly; refer to the operating instructions provided with the trap.
5.1 Cleaning
If required clean the turbomolecular pump of dust with a dry cloth.
5.2 Leybold Service

contaminated, specify exactly which substances are involved. You must use
the form we have prepared for this purpose.
A copy of the form has been reproduced at the end of these Operating
Instructions: “Declaration of Contamination for Compressors, Vacuum Pumps

Provide the form signed by an authorized person for each pump.
This statement detailing the type of contamination is required to satisfy legal
requirements and for the protection of our employees.
