3.8.1 Waste Disposal of Used Pump
Materials
The corresponding environmental and safety regulations
apply. This applies equally to used filters and filter
elements (oil filter, exhaust filter and dust filter).
– In the case of hazardous substances
determine the kind of hazard first and
observe the applicable safety
regulations. If the potential hazard still
persists, the pump must be
decontaminated before starting with any
maintenance work. For professional
decontamination we recommend our
Leybold service.
– Never exchange the oil or the filters
while the pump is still warm. Let the
pump cool down to uncritical
temperatures first. You must wear
suitable protective clothing.
3.9 Storing the Pump
Before putting a pump into operation once
more it should be stored in a dry place
preferably at room temperature (20 °C).
Before the pump is shelved it must be
properly disconnected from the vacuum
system, purged with dry nitrogen and the oil
should be changed too.
The inlets and outlets of the pump must be
sealed with the shipping seals which are
provided upon delivery.
The gas ballast switch must be set to the “0”
position and if the pump is to be shelved for
a longer period of time it should be sealed
in a PE bag containing some desiccant
(silica gel).
When a pump is put into operation after it has been
shelved for over one year, standard maintenance should
be run on the pump and the oil should also be
exchanged (see Operating Instructions). We recommend
that you contact the Leybold service.
