9. If warm cooling air from vacuum pumps is used in air heating systems, e.g. to
warm up a workroom, take precautions against air pollution and possible
contamination of the breathing air.
10. On water-cooled vacuum pumps using open circuit cooling towers, protective
measures must be taken to avoid the growth of harmful bacteria such as
Legionella pneumophila bacteria.
11. Do not remove any of, or tamper with, the sound-damping material.
12. Never remove or tamper with the safety devices, guards or insulations fitted
on the machine.

leave oil filler or drain plugs open during operation.
14. Do not use the pump as a compressor.
15. Never run the pump without the air intake filter mounted.
Note:
Also consult Safety precautions during installation on page 9 and Safety
precautions during maintenance or repair on page

.
These precautions apply to machinery processing or consuming air or inert
gas. Processing of any other gas requires additional safety precautions typical
to the application which are not included herein.
Some precautions are general and cover several machine types and
equipment; hence some statements may not apply to your machine.
