• Switch off the drive to the dispenser and lock it to prevent it from being switched on
again.
• Shut down the feed device.
• Release the admission pressure.
• Remove the stator and store it separately (see 4.2, Changing the stator, page 12).
• Dismantling / cleaning the dispenser (see 4.4, Dismantling the dispenser, Page 15).

3.4 Re-commissioning
Attention! Do not switch on the dispenser yet. If there is no product, there is a risk of
damage. Note section 2.3, Operating environment, prevention of material damage on
page 6. Even a brief period of dry running can lead to the stator being destroyed.
Attention! The dispenser and the drive unit may only be installed when the unit is
electrically dead. The motor take-off shaft must line up with the dispenser drive shaft. In
the event of incorrect installation there is a risk of increased wear and of metal being worn
off.
• Have the safety aspects of the dispenser checked and clarified by qualified
maintenance personnel (see 2.5.2, Service personnel, Page 7).
• Ensure that the dispenser is free of product residues.
• Fill the dispenser with product as outlined in section 3.2.1, Feeding product for the first
time, Page 10.
