INSTALLING BATTERIES
WARNING: Batteries emit hydrogen gas.
Explosion or fire can result. Keep sparks and open
flame away when charging.
FOR SAFETY: When servicing machine, wear
appropriate personal protection equipment as
needed. Avoid contact with battery acid.
BATTERY SPECIFICATIONS
Two 12 volt deep-cycle batteries.
Contact distributor or Tennant for battery
recommendations.
FOR SAFETY: Before leaving or servicing machine,
stop on level surface, turn off machine, remove key
and set parking brake if equipped.
1. Lift the recovery tank to access the battery
compartment (Figure 1).
FIG. 1
2. With adequate assistance, carefully install the

batteries as shown (Figure 2).
FOR SAFETY: When servicing machine, use a hoist
or adequate assistance when lifting batteries.
3. Using the supplied battery post boots, connect the
cables to the battery posts as shown (Figure 2).
Connect the machine’s black (- ) battery cable last.
Use insulated tools when working near batteries.
Machine Front
BLACK
RED
FIG. 2
IMPORTANT: Make sure that the machine’s battery
charger is properly set before charging. See
BATTERY CHARGER SETTINGS.
For machines shipped without batteries and
equipped with an off-board battery charger, the
machine’s battery discharge indicator (BDI) is
factory programmed for GEL batteries as the
default.
If installing flooded (wet) lead/acid or AGM
batteries, the BDI MUST be reprogrammed to
prevent battery damage and/or short run- time. See
BATTERY CHARGER SETTINGS.
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.
BATTERY PACK LIFT- OUT TRAY (Option)
Models equipped with the optional battery lift-out tray
for quick or frequent battery pack exchange.
FOR SAFETY: Before leaving or servicing machine,
stop on level surface, turn off machine, remove key
and set parking brake if equipped.
WARNING: Batteries emit hydrogen gas.
Explosion or fire can result. Keep sparks and open
flame away when charging.
1. Disconnect the battery cable connection at
machine(Figure3).
FIG. 3
FOR SAFETY: When servicing machine, wear
appropriate personal protection equipment as
needed. Avoid contact with battery acid.
2. Using an approved lift strap that supports the
weight of battery pack, connect the strap to the two
lift brackets as shown. Using a lift hoist rated to
handle the weight of the battery pack, carefully lift
the battery packs to and from machine. Keep one
hand on the battery lift-out tray when lifting for
stability (Figure 4).

OPERATION
Tennant T300 (03- 2015) 11
Before lifting battery pack, make sure the batteries
are secured to the battery lift- out tray with the
supplied battery strap as shown (Figure 4).
FIG. 4
3. Reconnect the battery cable connection after
installing battery pack.
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.
BRUSH AND PAD INFORMATION
For best cleaning results use the appropriate brush or
pad for your cleaning application. Listed below are
brushes and pads and the applications for which each
is best suited.
NOTE: The amount and type of soilage play an
important role in determining the type of brush or pad
to use. Contact a Tennant representative for specific
recommendations.
Soft nylon bristle scrub brush (White) -
Recommended for cleaning coated floors without
removing finish. Cleans without scuffing.
Polypropylene bristle scrub brush (Black) -
This general purpose polypropylene bristle scrub brush
is used for scrubbing lightly compacted soilage. This
brush works well for maintaining concrete, wood and
grouted tile floors.
Super abrasive bristle scrub brush (Gray) -
Nylon fiber impregnated with abrasive grit to remove
stains and soilage. Strong action on any surface.
Performs well on buildup, grease, or tire marks.
Polishing pad (White) -
Used to maintain highly polished or burnished floors.
Buffing pad (Red) - Used for light duty scrubbing
without removing floor finish.
Scrubbing pad (Blue) - Used for medium to
heavy-duty scrubbing. Removes dirt, spills, and scuffs
and leaves surface clean ready for recoating.
Stripping pad (Brown) - Used for stripping of floor
finish to prepare the floor for recoating.
Heavy duty stripping pad (Black) - Used for
aggressive stripping of heavy finishes/sealers, or very
heavy duty scrubbing.
Surface preparation pad (Maroon) - Used for very
aggressive chemical free removal of floor finish to
prepare the floor for re-coating

ec-H2O Scrubbing - Fill solution tank with only cool
clean water (less than 70°F/21°C). Do not add
conventional floor cleaning detergents. An ec-H2O
system fault will occur if cleaning detergents are added.
Conventional Scrubbing - Fill solution tank with
water (not to exceed 60°C/140°F). Pour a
recommended cleaning detergent into the solution tank
according to mixing instructions on the container.
NOTE: Do not use the ec-H2O system when there are
conventional cleaning detergents in the solution tank.

water before operating the ec-H2O system.
Conventional cleaning detergents will cause an
ec- H2O system fault.
WARNING: Flammable materials can cause an
explosion or fire. Do not use flammable materials
in tank(s).
ATTENTION: For Conventional Scrubbing, only use
commercially approved cleaning detergents. Machine
damage due to improper detergent usage will void the
manufacturer’s warranty.

ec-H2O NanoClean WATER CONDITIONING
CARTRIDGE (ec-H2O model)
The ec-H2O system is equipped with a water
conditioning cartridge (Figure 26). The cartridge is
designed to protect the machine’s plumbing system
from potential scaling.
The cartridge is required to be replaced when it reaches
its maximum water usage or expiration time of when the
cartridge was activated, which ever comes first.
Depending on machine usage a new cartridge can last
anywhere from 12 to 24 months.
The control panel will signal a code when it’s time to
replace cartridge. See SERVICE INDICATOR CODES
for further details.
FIG. 26
All cartridges are labeled with a manufacture date. The
shelf-life of an un-installed cartridge is one year from
manufacture date. For new cartridge replacement, the
ecH2O module timer must be reset. See ec-H2O
NanoClean WATER CONDITIONING CARTRIDGE
REPLACEMENT.
ATTENTION: During first time use and after replacing
the water conditioning cartridge, the ec-H2O system
