IMPORTANT: Before charging batteries, make sure
the battery charger and the machine's battery
discharge indicator are properly set for battery
type. Failure to properly set will result in battery
damage. See BATTERY CHARGER SETTINGS.
ATTENTION: Do not disconnect battery cables
while charger is plugged in, circuit board damage
may result.
IRIS ® Battery Charging Metrics Notification:
Machines equipped with capability to report battery
charging data via IRIS are supplied with a charger and
set of batteries from the factory. When a battery
reaches its end of life and must be replaced, Tennant
highly recommends that the same battery type be used
to continue to maximize the machines performance. In
the event a battery with a different amp hour (AH), type
(Flooded, AGM, Gel), or manufacturer is selected for
replacement please contact Tennant technical service
department for assistance in determining the feasibility
of the replacement batteries and if so, selecting the
correct charging profile. Availability of IRIS battery
metric reporting is not guaranteed with third party
supplied batteries.

HOW THE MACHINE WORKS
Conventional scrubbing:
When using the conventional scrubbing mode, water
and detergent mixture from the solution tank flows to
the floor and the rotating brush(es)/pad(s) scrub the
floor clean. As the machine moves forward, the
squeegee with vacuum suction picks up the dirty
solution from the floor into the recovery tank.
ec-H2O NanoClean Technology (option):
When using the ec-H2O NanoClean technology,
normal water passes through a module where it is
electrically converted into a cleaning solution. The
electrically converted water attacks the dirt, allowing
the machine to easily scrub away the suspended soil.
The converted water then returns to normal water in
the recovery tank.

for supervisor use only. Remove pages from manual if
necessary.
