Maintenance
We recommend a standard bearing change after 15,000 operating hours at
the latest. Moreover, we are recommending an exchange of the rotor unit
after 45,000 operating hours at the latest.
Such maintenance work can only be done by the Oerlikon Leybold Vacuum
Service. If required contact the Oerlikon Leybold Vacuum service center nea-
rest to your location. You can find the address on our internet page
www.oerlikon.com.
At high pump loads - for example during cyclic operation, at high gas
throughputs or at high ambient temperatures - the aforementioned mainten-
ance work should be carried forward.
When an adsorption trap is used, regenerate or renew the adsorption agent
regularly; refer to the operating instructions provided with the trap.
The frequency converter is maintenance free.
