4. Re-install the battery tray and batteries in machine.
5. Re-install the seat panel and reconnect the seat wire
harness. Do not re-stall and the battery compartment
shroud at this time, the ec-H2O system will need to be
tested for leaks first as described later in the
instructions.
PROGRAM THE ec-H2O MODULE:
Set Machine Configuration:
Refer to table below for proper machine configuration.
1. Turn key to the on position.
2. To view the current machine configuration, press and
hold the solution flow button on the ec-H2O module.
The solution flow lights will momentarily turn off after 2
seconds. Release the button when the LEFT solution
flow indicator light turns on, in approximately 4
seconds (Figure 37). When the button is released, the
solution flow indicators will blink the current machine
configuration for 10 seconds (see Table). After the 10
second window, the lights will revert back to normal
operation. Repeat step to re-enter program.
Attention: If you hold the solution flow button too long, you
may enter the firmware mode. To exit from this mode, press
the solution flow button and repeat step 2.

Operate the Self-Test Mode to Recognize the
ec-H2O System:
1. Press and hold down the ec-H2O button and Vacuum
button (Figure 38).
2. Turn the key switch to the ON ( I ) position.
3. Wait 10 seconds then release the two buttons.
The self- test mode will take approximately 40
seconds to run.
After the self- test mode is complete, the One-Step
button LED should be lit solid.
If a LED is blinking, an open wire connection was
found. Check all wire connections and repeat test.

CHECK THE ec-H2O NanoClean SYSTEM
FOR PROPER OPERATION:
To ensure the ec-H2O NanoClean system is operating
properly, perform the following.
1. Connect the cartridge by-pass tool, provided
separately, to the two green hoses as shown. Route
the clear discharge hose to the floor. The use of the
cartridge by-pass tool is to prevent activating the
ec-H2O water conditioning cartridge during the check
process (Figure 39).

By-pass Tool
Fig. 39
2. Fill solution tank with cool clean water (less than
21C/70F). Do not add any conventional floor
cleaning detergents, system failure may result.
3. Turn the key to the on ( I ) position. Verify that the 4
LED’s on the module flash on for one second and
then turn off, followed by displaying the current flow
rate setting (Figure 40).
Fig. 40
4. Press the ec-H2O system button to the on ( I )
position.
5. The ec-H2O system indicator light will turn on when
the propel pedal is pressed (Figure 41).
Solid Green Light = Normal operation
Solid or blinking Red Light = System fault
Check all ec-H2O wire harness connections
and refer to Service Manual.

6. Operate the ec-H2O module in Manual Mode (See
NOTE below). Verify that the ec-H2O system is
putting water on the floor at the scrub head and at the
By-Pass Tool hose.
7. Check all ec-H2O system hose connections for water
leaks.
NOTE: To enter the module’s Manual Mode, depress and
hold the service switch for 20 seconds and release (Figure
42). The first and third green LEDs will alternate on and
off indicating that you are in the Manual Mode and the
ec-H2O pump will be operating. To exit the Manual Mode,
depress the Service Switch for one second and release.
The module will also exit the manual mode automatically
after 7 minutes.

8. After checking machine for proper operation or
possible leaks, drain all tanks and vacuum out any
residual water. With the ec-H2O module in Manual
Mode, attach the hose from from the By-pass Tool to
a vacuum unit and vacuum out any remaining water
from module.
9. Exit the Manual Mode and remove the Cartridge
By-pass Tool from machine. To exit Manual Mode,
depress the Service Switch for one second and
release.

INSTALL ec-H2O WATER CONDITIONING
CARTRIDGE:
1. Check the manufacture date on the Water
Conditioning Cartridge before installing. The shelf-life
of an un-installed cartridge is one year from
manufacture date. Discard cartridge if shelf-life has
expired. For replacement Cartridge, order p/n
9013646.
2. Fill in the installation date on the Water Conditioning
Cartridge label (Figure 43).

3. Remove the two plugs from cartridge. Press the gray
collars inward and pull plugs outward to remove
(Figure 44). Position the cartridge in the cartridge
holder bracket as shown and connect green hoses to
cartridge (Figure 44). Make sure the hose connectors
are fully inserted.

Set Timer for Water Conditioning Cartridge:
Carefully read and understand the following steps before
performing procedure.
1. Turn key to the on position (Figure 45).
2. Press and hold the service switch on the module for
10 seconds. After releasing the service switch, the
three solution flow indicator lights will begin to (ripple)
move back and forth.
Attention: If you hold the service switch too long, the 1st
and 3rd lights will alternate on and off. If this happens,
press and release the service switch and repeat step 2.
3. Within 5 seconds after releasing the service switch,
while the three indicator lights are still moving back
and forth (ripple), press the quickly release the
solution flow button located on ec-H2O module.
4. The indicator lights will then blink three times to
confirm timer has been set. Repeat process if the
three indicator lights do not blink three times.
