Solution System
Functional Description
Overview
The solution system
delivers water, or
detergent and water, to
the floor for the scrub
system. The standard
solution system includes
the
Solution Tank
, solution-
empty switch,
Solution
Shutoff Valve
,
Solution Filter
,
Solution Pump
(M4),
Main
Solution Solenoid Valve
(L10), and the associated
plumbing to distribute
solution to the
Scrub
Brushes
. A capped
Solution
Drain Hose
allows you to
drain the solution tank.
The solution flows to the
Scrub Brushes
any time the
scrub system is enabled,
the scrub deck is lowered
and the drive pedal is not
in the neutral position.
Programming options
allow you to enable or
disable solution flow when
the machine moves in
reverse.
When the scrub system is disabled, no solution will flow to the
Scrub Brushes
regardless of drive pedal or
scrub deck position. The operator can enable the solution system independent of the scrub system to pre-wet
the floor before enabling the scrub and/or recovery systems.
The solution system also provides solution to the following optional equipment if the machine is so equipped:
• Right side scrub brush,
• DustGuard
™
system spray nozzles,
• Wash hose.
Solution Flow Control
The electric solution pump and main solution solenoid valve control the solution flow to the main scrub
brushes. The main solution solenoid valve opens when the solution system switches on. A Pulsed Width
Modulated (PWM) output from
J3-2
on the Drive Box controls the speed of the solution pump to regulate
solution flow to the brushes.
