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, pur-
ged 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 Section 5.2). We recommend that you contact the
Leybold Service.
