Solution System 67Service Manual – Focus II / Scrubtec R6 Rider Autoscrubber
Solution System
Functional Description
The Focus solution tank is incorporated directly
into the main body of the machine. A clear tube
on the left side of the machine below the ll cap
serves as a water level indicator for the tank.
At the outlet of the solution tank under the
machine, is a manual shutoff valve followed by
a serviceable solution lter that prevents debris
from entering the rest of the solution system
followed by a solution solenoid.
Solution Solenoid
The solution solenoid is located downstream
from the solution lter, and activates to allow
solution to ow to the scrub deck. To prevent
pooling of excess water on the oor when the
machine is stationary, the solenoid output
from the controller is disabled when the wheel
drive is not active. The rate of solution ow is
controlled by cycling the solution solenoid on
and off at varying duty cycles with a 6-second
cycle period.

Detergent Models
Machines that have on-board detergent mixing
use a pump-driven, detergent injection system. The detergent is stored in the removable detergent tank,
which has a suction hose from the detergent pump. The detergent pump draws the liquid from the detergent
tank and injects it into the solution line between the solution solenoid and the scrub deck. The ow rate of
the detergent is controlled by the Main Machine Controller using PWM.
