Solution System
Functional Description
Overview
The solution system provides the Water and detergent mixture to the scrub brushes. Water and detergent
are added to the solution tank for Standard (non-EcoFlex) SC6500 models. EcoFlex models have a separate
detergent tank. On both standard and EcoFlex models the Drain Hose allows you to drain the Solution Tank by
removing the Drain Plug.
On standard (non-EcoFlex) models, the solution is gravity fed through the plumbing to the scrub deck. The
solution solenoid is spring loaded closed to block the uid. The A2 Control Board provides pulsed-width-
modulated (PWM) voltage to the Solution Solenoid to regulate the solution ow rate.
On EcoFlex models, a solution pump is used to move uid from the solution tank to the scrub deck. The A2
Control Board provides pulsed-width-modulated (PWM) voltage to the Solution Control Pump to regulate the
solution ow rate. Note that the Solution Solenoid Valve is full-open whenever the solution system is switched
on.
On EcoFlex models, when the detergent system is switched on, the solenoid style Detergent Pumps inject
detergent into the solution sytem plumbing. The A2 Control Board provides PWM voltage to the Detergent
Pumps
to regulate the detergent ow.
