First insert the cover r at the top and then tighten thetwo screws e at the bottom.Problem Possible Cause RemedyPump runs, but the suctionaction doesn’t take placePump sucks in air at a joint. v Seal connections on suctionside so are airtight.Leaky or damaged suctionhose.v Check suction line for damageand seal so is airtight.The pump was not filled withthe liquid to be pumped.v Fill the pump(see “4. Operation”).The liquid escapes over thehose which is connected tothe delivery side during thesuction action.1. Fill the pump again(see “4. Operation”).2. When starting operation holdthe pressure hose approx.1 m vertically above thepump, until the suctionaction has taken place.Absolutely vacuum-resistant connection is achieved by usingGARDENA Suction Hoses (see point “8. Available accessories”).Leaky screw fitting 6 at the fillercap 7.v Check seal (replace if neces-sary) and tighten connectionsecurely (do not use pliers).Air cannot escape, since deliveryside is closed or remaining wateris in the pressure hose.v Open shut-off valves(e. g. nozzle) in the deliveryline, empty the delivery hoseor disconnect it from thepump during priming.The waiting time wasn’tobserved.v Switch on the pump and waitup to 5 min.Suction filter or backflow prevent-er in the suction hose clogged.v Clean the filter or the backflow preventer.Too high suction height. v Reduce suction height.In case of any other difficulties concerning the suction action,use GARDENA Suction Hoses with Backflow Preventer(see point “8. Available accessories”) and fill in the liquid tobe pumped over the filler cap 7 before operation.Problem Possible Cause RemedyPump motor runs,but delivery capacityor pressure suddenlydecreasesSuction filter at the suctionhose is sucked free.v Reduce flow rate on thedelivery side with a controlvalve, e.g. GARDENAart. no. (2)977.Suction filter or backflowpreventer clogged.v Clean filter or back-flowpreventer.Leaks at suction side. v Eliminate leak.Impeller blocked. v Release impeller.Pump motor doesn’t startor suddenly stopsNo power. v Check fuses and electricconnections.Circuit breaker has switched offthe motor due to overheating /overload.v Ensure sufficient cooling /ventilation and clean theimpeller chamber.Electric failure. v Send the pump to oneof our GARDENA ServiceCentres.5000/5; 6000/6 inox:Pump delivers andLED flashes orangeThe flow sensor is dirty. v Clean the flow sensor.5000/5; 6000/6 inox:Pump switches off andthe LED shines redNo supply of fluid to bepumped for approx. 5 minutes /leakage on the suction side.v Establish supply of fluid tobe pumped/check suctionline and re-start pump.The pump ran for approx.5 minutes against the closeddelivery side.v Open the delivery side andre-start pump.For any other malfunctions please contact the GARDENA service department.Repairs must only be carried out by GARDENA service departments or specialistdealers authorised by GARDENA.8.
