Shelving after Use
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 con-
taining some desiccant (silica gel).
Before putting a pump into operation once more it should be stored in a dry
place preferably at room temperature (20 °C = 68 °F).
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. We recommend that you contact the Leybold service.
