authorised by Oerlikon Leybold Vacuum to do so.
5.1
Maintenance Intervals
After 15,000 operating hours at the latest a standard bearing exchange will
be recommended for the
TURBOVAC 35
to
361 C
. For the
TURBOVAC 600 C
and 1000 C
a standard bearing exchange will be required after 10,000 opera-
ting hours at the latest.
Moreover we recommend to have the rotor assy. exchanged , depending on
the thermal stress on the rotor, after 45,000 to 100,000 operating hours. This
can only be done by Oerlikon Leybold Vacuum Service. For this ask for a
quotation.
When using purge gas valves
Depending on the degree of contamination of the purge gas used the filter
will clog and will have to be exchanged (our experience indicates that this will
become necessary after 1 to 6 months).
When using an adsorption trap
Regenerate or renew the adsorption agent regularly; refer to the operating
instructions provided with the trap.
