Description
1.2.1 Transporting
• Pumps which are filled with operating
agents must only be transported standing
upright. Otherwise oil may come out of the
pump. During transportation avoid any other
orientations.
• Check the pump for the possible presence
of oil leaks. There exists the danger that
someone may slip on spilt oil.
• In order to lift the pump only use the eyes
provided on the pump for this purpose and
only use the required type of lifting equip-
ment (see Operating Instructions, 7/4).
Make sure that the lifting equipment has is safe to ope-
rate. Use only suitable lifting gear. Make sure that all
safety regulations are observed.

1.2.2 Shelving
• Before putting a pump into service once
more, store it at a dry place, preferably at
room temperature (20 °C). Before shelving
a pump disconnect it properly from the
vacuum system, purge it with dry nitrogen
and do an oil change.
All inlet and discharge openings on the
pump must be sealed with the shipping
seals supplied with the pump.
Set the gas ballast switch to the “OFF” posi-
tion; if the pump is to be shelved for a lon-
ger period of time you should place it in a
PE bag containing some dessicant (silica
gel) and the firmly seal the bag.
When shelving the pump for over one year, you should
run maintenance on the pump and also do an oil change
before putting the pump into service again. We recom-
mend that to get in touch with Leybold Service in such a
case.
