harness.
PREPARE MACHINE FOR KIT INSTALL:
1. Drain the solution tank and recovery tank.
2. Park the machine on a level surface. Lower the
scrub head and remove the key.
FOR SAFETY: Before installing kit, disconnect
battery cables.
3. Remove the front shroud.
4. Disconnect the actuator at the scrub head.
5. Remove the actuator roller guide brackets and

INSTALL ec- H2O WIRE HARNESS:
1. Using a Fish--Tape, route the ec--H2O wire
harness through the harness channel along side
the machine’s main wire harness (Figure 3). Pull
the harness from the front of the machine to the
back (Figure 3).

OPERATE THE ec- H2O SYSTEM:
To ensure the ec--H2O system is operating properly,
perform the following:
1. Fill solution tank with cool clean water (less than
70°F/21°C). Do not add any conventional floor
cleaning detergents, system failure may result.
2. Turn the key to the on ( I ) position.
3. Press the ec--H2O system button to the on ( I )
position.
4. The ec--H2O system indicator light will not turn
on until you begin scrubbing with the machine
(Figure 27).

4. Check all hose connections for water leaks.
If storing the machine in freezing temperatures, make
sure all water is removed from the machine, including
the the ec--H2O module.
