5.6.4 Connecting the overflow and deaerationlinesNoteWarningObserve chemical resistance!HV-variant pumps have an assistingsuction. In this case, prepare (cut) thedeaeration line, but do not connect ityet!The pump has a deaeration line (PVC 4/6).• Connect the deaeration line (J) to the connectionfor the deaeration line (I).Fig. 21 Connection for the deaeration lineFor pumps with Plus 3 systemThe pump has a deaeration line (PVC 4/6).• Connect the deaeration line (J) to the connectionfor the deaeration line (I).• Connect the overflow line (H) (PVC tube 8/11) tothe connection (G).ITM03 6237 45065.6.5 Installing the overflow and deaeration lines• Shorten the overflow line (H) and deaeration line(J) to at least 10 mm above the maximum tanklevel.• Insert the overflow line (H) and deaeration line (J)downwards into the dosing tank or collectioncontainer. Avoid loops.Fig. 23 Overflow and deaeration linesCautionCautionMin. 10 mmMax.H, J6. Electrical connectionsMake sure that the pump is suitable for the electricitysupply on which it will be used.TM03 6239 4506Dosing medium can leak from theoverflow and deaeration lines. Routeboth lines into a collection container orthe tank!Do not immerse the overflow line anddeaeration line in the dosing medium!Observe the pressure limits specified insection 1. General information!GHFig. 22 Plus 3 systemITM03 6238 4506WarningElectrical connections must only becarried out by qualified personnel!Disconnect the power supply beforeconnecting the power supply cable andthe relay contacts!Observe the local safety regulations!WarningThe pump housing must only beopened by personnel authorised byGrundfos Alldos!WarningProtect the cable connections andplugs against corrosion and humidity.Only remove the protective caps fromthe sockets that are being used.CautionThe power supply must be electricallyisolated from the signal inputs andoutputs.24
