Solution System
Solution System
Functional Overview
The main body of the machine also serves as the solution tank. The solution tank has a fill capacity of 30 gallons
(114 liters). All models use one right rear tank fill opening for ease of filling. A serviceable Solution Filter is
plumbed into the manual solution shutoff valve outlet to keep debris from entering the solenoid valve. Also fitted to
the tank is a flexible drain hose that also serves as a water level sight tube.
The solution system uses an electrical Solenoid Valve
(L1)
which stops and starts the solution flow to the scrub
brushes. The electrical circuit that turns on (energizes) the solenoid coil is activated through the
(A1)
control
panel’s solution switch button input and the FWD / REV
(A2)
Speed Controller voltage output signals.
Note
: See
the
Know Your Machine
section in this manual for a complete explanation of the solution operation modes.
During normal machine scrubbing, the solution system’s Auto Mode is selected and works in conjunction with the
wheel drive speed controller and the
(A1)
main controller’s scrub system outputs to turn the
(L1)
solenoid valve
on and off. The solution will flow to the scrub brushes when the scrub deck is lowered and a palm drive button is
pressed.
Note
: When the solution on/off button is turned off, no flow can occur while the machine scrub deck is
down and a palm drive button is pressed.
On EcoFlex models, a small chemical pump draws chemical (detergent) from the detergent tank and injects it into
the solution hose just upstream from the scrub deck. The flow rate of the detergent is controlled by the main control
board using pulse width modulation (PWM) to the pump.
