8 Decommissioning
8.1 Shutting down for longer periods
Before shutting down the pump, observe the following instructions to adequately protect the interior of
the pump (pumping system) against corrosion:
1. Shut down the vacuum pump and allow it to cool.
2. Remove the pump from the vacuum system if necessary.
3. Change the operating fluid.
4. Start the pump and bring it to operating temperature, in order to wet the inside of the pump with
fresh operating fluid.
5. Fill the pump to above the
“max.” mark
with operating fluid, up to the upper edge of the sight
glass.
6. Close the vacuum and exhaust flanges with the original screw caps.
7. Store the pump only in dry, dust-free rooms, within the specified ambient conditions.
8. In rooms with humid or aggressive atmospheres: Hermetically shrink-wrap the pump together with
a drying agent in a plastic bag.
9. For longer storage periods (> 2 years), Pfeiffer Vacuum recommends changing the operating fluid
again prior to recommissioning.
8.2 Recommissioning
NOTICE
Risk of damage to pump as a result of operating fluid aging
The operating fluid usability is limited (max. 2 years). Prior to recommissioning, following a shutdown
of
2 years or more
, carry out the following work.
► Change the operating fluid.
► Change the radial shaft seal rings and other elastomer parts if required.
► Observe the maintenance instructions – consult Pfeiffer Vacuum if necessary.
Ejection of operating fluid
!
Danger of operating fluid ejection at the exhaust connection due to overfilling.
● Drain operating fluid to the normal level prior to recommissioning.
8.3 Disposal
WARNING
Health risk and environmental damage due to poisoning on toxic contaminated parts or devi-
ces
Toxic process media result in contamination of the devices or parts thereof. During maintenance work
there is a health risk due to contact with these poisonous substances. The non-permitted disposal of
toxic substances results in environmental damage.
► Take appropriate safety precautions and avoid health risks or environmental hazards due to toxic
process media.
► Decontaminate the affected parts before carrying out maintenance work.
► Wear protective equipment.
► Dispose all substances safely and in accordance with the locally applicable regulations.
