5.2 Lining up the pipe systemEnsure that the pipe system is adequately underpinned with pipe supportssothatthepumpbodyisnotsubjecttostrainfromortheweightofthepipesystem.

Caution! Duringthesuctionprocess,thepumpmaytendtovibrate.Apipesupportshouldbeplacedclosetothepumpsuctiontopreventpipeworkvibrationcreatingexcessivenoise.

6. Start-up and operation

Beforestartingthepump,dismantleandcleanthesuctionpipe. Anyforeignmaterialinthepumpshouldberemoved.

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

1. Disconnectthepowersupply.

2. Removethepumpbody(items1a,1b)byunscrewingtheclampring(item9a)orbodyscrews,andcarefullyextractfromthebody.

3. Turntheimpeller(item4)toensurethatthereisnoforeignmaterialbehind it.

4. Removeanyforeignmaterialfrominsidethepump.

5. Whenthepumpbodyiscleanandfreeofforeignmaterial,reassemblethe pump.

Mountthepumpbodyasdescribedbelow:
