Recovery System90Service Manual
SC6500|Recovery SystemFunctional DescriptionOverviewThe recovery system picks up thescrubbing solution from the squeegeetool and directs it to the Recovery Tank.Recovery TankThe Recovery Tank holds 70 gallons[265 l] of wastewater and supports theVacuum Motor, Recovery Tank Lid andTop Cover Assembly.Vacuum MotorThe Vacuum Motor draws air from theRecovery Tank to create a vacuum inthe tank and at the Squeegee.The Vacuum Motor switches onautomatically when the scrub systemis enabled and the machine movesforward. The Vacuum Motor will switchoff after a predetermined time delayonce machine motion stops.The Vacuum Motor can also be switched on independent of the scrub system by pressing the vacuum/wandswitch. This is used to pick up solution already on the floor, or when using a wand on the Squeegee Hose.A current sensor monitors the Vacuum Motor current and will display a fault if the Vacuum Motor currentdraw is too high.Squeegee and Squeegee HoseThe wastewater and air enter the vacuum system at the Squeegee tool through small openings (notches)located in the front Squeegee blade. The small openings are the entrance points for the water and air andhelp speed up the airflow, producing the suction to lift the wastewater off of the floor. The solution travelsthrough the Squeegee Hose at high speed and into the Recovery Tank. The airflow continues through theRecovery Tank, vacuum fan inlet screen and Vacuum Motor, then is exhausted out of the Vacuum Hose. Nowastewater ever actually moves through the Vacuum Motor, just the working air.Vacuum MotorVacuumHoseTop CoverAssemblyFloat Cageand BallRecoveryTank CoverCoverGasketDrainHoseRecoveryTankSqueegeeHoseSqueegee
