12. The oil separator tank can be slightly pressurised. Do not open and do not leave oil filler or drain plugs
open during operation.
13. Do not use the pump as a compressor.
14. Never run the pump without the air intake filter mounted.
15. 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.
Also consult sections Safety precautions during installation and Safety precautions during
maintenance or repair. 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.
1.5 Safety precautions during maintenance or repair
All responsibility for any damage or injury resulting from neglecting these precautions, or non
observance of the normal caution and care required for installation, operation, maintenance
and repair, even if not expressly stated, will be disclaimed by the manufacturer.
Precautions during maintenance or repair
1. Always use the correct safety equipment (such as safety glasses, gloves, safety shoes, etc.).
2. Use only the correct tools for maintenance and repair work.
3. Use only genuine spare parts.
4. All maintenance work shall only be undertaken when the machine has cooled down.
5. A warning sign bearing a legend such as "Work in progress; do not start" shall be attached to the
starting equipment.
6. Persons switching on remotely controlled machines shall take adequate precautions to ensure that
there is no one checking or working on the machine. To this end, a suitable notice shall be affixed to
the remote start equipment.
7. Before removing any component, effectively isolate the machine from all sources of under- and/or
overpressure and make sure that the pump system is at atmospheric pressure level.
8. Never use flammable solvents or carbon tetrachloride for cleaning parts. Take safety precautions
against toxic vapors of cleaning liquids.
9. Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the parts
and exposed openings with a clean cloth, paper or tape.
10. Never weld or perform any operation involving heat near the oil system. Oil tanks must be completely
purged, e.g. by steam cleaning, before carrying out such operations. Never weld on, or in any way
modify, pressure vessels.
11. Whenever there is an indication or any suspicion that an internal part of a machine is overheated, the
machine shall be stopped but no inspection covers shall be opened before sufficient cooling time has
elapsed; this to avoid the risk of spontaneous ignition of the oil vapor when air is admitted.
12. Never use a light source with open flame for inspecting the interior of a machine, pressure vessel, etc.
13. Make sure that no tools, loose parts or rags are left in or on the machine.
14. All regulating and safety devices shall be maintained with due care to ensure that they function
properly. They may not be put out of action.
15. Before clearing the machine for use after maintenance or overhaul, check that operating pressures,
temperatures and time settings are correct. Check that all control and shut-down devices are fitted and
