8.1 Shutting down for longer periods
Before shutting down the pump, observe the following procedure and adequately
protect the pump system against corrosion:

Switch off pump.

Change operating fluid (see p. 20, chap. 7.2) .

Start the pump and allow the pump to warm up.

Fill up the pump with new operating fluid to the top edge of the sightglass.

Close vacuum flange and exhaust flange with locking caps.
8.2 Re-starting
Visually inspect the inner of the pump before taking it into operation. If there is ev-
idence of rust on the parts of the pump which form the housing, then do not take
it into operation and contact Pfeiffer Vacuum Service.
In accordance with DIN 7716 and the manufacturer's specifications we recommend
replacing the installed elastomer parts after 2 years.

If drying pearls were inserted then they should be removed now. Improper
handling can cause failure of the pump.

etc.) may cause environmental burden.
