5.9 Service at Leybold
If you send a pump to Leybold indicate whether the pump is free of sub-
stances damaging to health or whether it is contaminated.
If it is contaminated also indicate the nature of the hazard. To do so, you
must use a preprinted form which we shall send to you upon request.
A copy of this form is reproduced at the end of these Operating Instructions:
“Declaration of Contamination of Compressors, Vacuum Pumps and
Components”. Moreover, you may download a suitable form from the
Internet: www.leybold.com Docu ments Download Documents.
Please attach this form to the pump or enclose it with the pump.
This “Declaration of Contamination” is required to meet the requirements of
German Law and to protect our personnel.
Leybold must return any pumps without a “Declaration of Contamination” to
the sender’s address.
Before packaging (respectively shipping) the pump it should, if possible, be
purged with inert gas, but as a minimum requirement it should be completely
emptied of all pumped substances.
This may also apply to all parts belonging to the pump system, like coolers,
vessels, etc.
Package the pump so that it will not be damaged during shipping and so
that no hazardous substances can escape from the packaging.
Before transporting the pump, drain out the oil!
For transporting, the pump has been fitted on to a special pallet, please
retain this pallet in case the pump needs to be returned.
