2 Transport and Storing
To lift the pumps only use the crane eyes provided for this purpose, re-
spectively use corresponding lifting facilities. When connecting or remov-
ing the pump, do not move under hoisted loads.
If possible transport the pump in its original packaging, if not available
exercise due care.
Pumps which are filled with oil must only be moved while standing upright,
otherwise oil may escape. Avoid any other orientations during transport. Check
the pump for the presence of any oil leaks, since there exists the danger that
someone may slip on spilt oil.
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 stored it
must be properly disconnected from the vacuum system, purged with dry nitro-
gen 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 close position and if the pump is to
be stored 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 stored for over one year,
standard maintenance should be run on the pump and the oil should also be
exchanged (see Section 5.4). We recommend that you contact the Leybold
Service.
