SC6500|Solution SystemFunctional DescriptionOverviewThe solution system provides the Water and detergent mixture to the scrub brushes. Water and detergentare added to the solution tank for Standard (non-EcoFlex) SC6500 models. EcoFlex models have a separatedetergent tank. On both standard and EcoFlex models the Drain Hose allows you to drain the Solution Tank byremoving the Drain Plug.On standard (non-EcoFlex) models, the solution is gravity fed through the plumbing to the scrub deck. Thesolution solenoid is spring loaded closed to block the fluid. The A2 Control Board provides pulsed-width-modulated (PWM) voltage to the Solution Solenoid to regulate the solution flow rate.On EcoFlex models, a solution pump is used to move fluid from the solution tank to the scrub deck. The A2Control Board provides pulsed-width-modulated (PWM) voltage to the Solution Control Pump to regulate thesolution flow rate. Note that the Solution Solenoid Valve is full-open whenever the solution system is switchedon.On EcoFlex models, when the detergent system is switched on, the solenoid style Detergent Pumps injectdetergent into the solution sytem plumbing. The A2 Control Board provides PWM voltage to the DetergentPumps to regulate the detergent flow.EcoFlex Solution System PlumbingSolutionTankDrainHoseDrainPlugShutoffValveDetergentTankDetergentPumpsDisc Scrub Brushes Cylindrical Scrub BrushesSolutionPumpIn-lineSolutionFilterSolutionManifoldSolutionSolenoidValve
