FILL THE SOLUTION TANK
Open the Solution Tank Fill Cap (41) then fill the tank with a maximum of 14 US gallons (53 liters) of cleaning solution. The amount of solution in
the tank can be observed by looking at the Solution Tank Level Sight Tube (38).
The machine is equipped with EcoFlex a detergent dispensing system. When using this system the solution tank should be filled with plain water.
The machine can also be used conventionally with detergent mixed with water in the tank. Always follow the dilution instructions on the detergent
container label. The solution should be a mixture of water and the proper cleaning detergent for the job.
CAUTION!
Use only low-foaming, non-flammable liquid detergents intended for automatic scrubber machine applications. Water temperature
should not exceed 130 degrees Fahrenheit (55 degrees Celsius).
NOTE: When refilling the solution tank always empty the recovery tank using Recovery Tank Drain Hose (37).
SOLUTION TANK INDICATOR
See Figure 2-7. The solution pump can sense when there is no solution present and send a signal that the solution tank is empty. Once the tank
is empty the Solution Empty Indicator (X23) will flash on the display.

FILL THE DETERGENT TANK
CAUTION!
Always follow the instructions on the labels of the detergent bottles when using floor
cleaning detergents. Wear the appropriate personal protective equipment such as
gloves and eye protection when handling floor cleaning detergents.
The Detergent Cartridge (3) is located under the Control Panel Housing (20). Fill the detergent
cartridge with a maximum of 1 gallon (4 Liters) of detergent. SERVICE NOTE: Remove the
detergent cartridge from the machine prior to filling to avoid spilling detergent on the machine.
It is recommended that a separate cartridge be used for each detergent you plan to use. The
detergent cartridges have a white decal on them so you can write the detergent name on each
cartridge for clarification. When installing a new cartridge, remove the factory cap and place the
cartridge in the machine. Install the Dry Break Cap (AA) as shown in Figure 2-8.
The system should be purged of previous detergent when switching to a different detergent (see
"To Purge When Changing Detergent" in the Detergent System Use Section).
