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 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 A2
Control Board provides pulsed-width-modulated (PWM) voltage to the
Solution Control Pump
to regulate the
solution flow 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 flow.
