Beforestartingthepump,dismantleandcleanthesuctionpipe. Anyforeignmaterialinthepumpshouldberemoved.

6.1 Checking the pump for foreign materialRemovethepumpbodyasdescribedbelow.Thesectionaldrawing(page3)istobeusedforreference.

1. Disconnectthepowersupply.

2. Removethepumpbody(items1a,1b)byundoingtheclampring(pos.9a)orbodyscrewsandcarefullypulloffthepumpbody.

3. Turntheimpeller(item4)toensurethatthereisnoforeignmaterialbehind it.

4. Ifthereisanyforeignmaterialinthepump,removeit.

5. Whenthepumpbodyiscleanandfreeofforeignmaterial,reassemble the pump.
