5 Servicing
The pump is maintenance-free. We recommend that a precautionary service
(an overhaul at the Leybold Service Centre) be carried out after 35,000 hours
of operation or after five years of service life at the latest, whichever occurs
sooner. The pump is fitted with a counter for this purpose, which shows the
remaining number of days of operation until the next recommended service
on the pump’s display. For a long pump life we recommend regular service
by Leybold.
The recommended service intervals refer to continuous operation with inlet
pressures below 50 mbar and the pumping of non-condensable gases. In
case of frequent operation above 50 mbar, frequent pumping cycles or when
pumping condensing gases, we recommend shortening the service intervals.
Please contact Leybold.
1000 hours before reaching the recommended service interval, the display
will show the message SEr alternating with the down-counting hours remain-
ing and the current speed. If the recommended service interval is exceeded,
the message toggles between SEr and the current speed.
Within the pumps, fluoropolymers are used as a sealant (FKM) and as a
lubricant (PFPE). In case the pump suffers severe mechanical damage, it
cannot be ruled out that toxic and/or corrosive substances may be
released due to thermal decomposition. Do not open the pump module,
and close off the inlet and exhaust flanges using blank flanges.
The pump is equipped with EMC devices on the input side. Observe this
during device tests/commissioning.
5.1 Leybold Service
Whenever you send us in equipment, indicate whether the equipment is con-
taminated or is free of substances which could pose a health hazard. If it is
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
and Components”. Another suitable form is available from www.leybold.com
-> Downloads -> Download Documents.
Attach the form to each pump.
This statement detailing the type of contamination is required to satisfy legal
requirements and for the protection of our employees.
We must return to the sender any equipment which is not accompanied by a
contamination statement.
