RED

FOAM SPACER

FIG. 3

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.

OPERATION

Tennant T500 (01-2017) 13

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.

parking brake if equipped.

The lifetime of the batteries depends on their proper

maintenance. To get the most life from the batteries;

SDo not charge the batteries more than once a day

and only after running the machine for a minimum of

15 minutes.

SDo not leave the batteries partially discharged for

long period of time.

SOnly charge the batteries in a well-ventilated area to

prevent gas build up. Charge batteries in areas with

ambient temperatures 80ºF/27ºC or less.

SAllow the charger to complete charging the batteries

before re-using the machine.

SMaintain the proper electrolyte levels of flooded (wet)

batteries by checking levels weekly.

Your machine is equipped with either flooded (wet)

lead-acid or maintenance-free (Sealed AGM) batteries

supplied by Tennant.

FOR SAFETY: When servicing machine, keep all

metal objects off batteries. Avoid contact with

battery acid.

MAINTENANCE-FREE BATTERIES

Maintenance-free (Sealed AGM) batteries do not

require watering. Cleaning and other routine

maintenance is still required.

ATTENTION: The following instructions are intended

for supervisor use only. Remove pages from manual if

necessary.

SUPERVISOR CONTROLS

The supervisor controls feature allows a supervisor to

program the machine's scrubbing settings for operator

use. The lockout functionality will prevent the operator

from changing or saving the Zone Settings.

The supervisor controls feature will lower machine

variability for consistent, repeatable cleaning results,

provide machine quality assurance regardless of user

experience, and reduce user training requirements.

PRO-MEMBRANE CONTROL PANEL MODEL

The machine has three supervisor control modes of

operation to choose from:

Unlocked Mode 1: Operator has full control of all

scrubbing parameters with the ability to reconfigure the

preset zone control buttons. The Unlocked Mode 1 is

the factory default setting.

Lockout Mode 2: Zone control buttons are preset and

locked by supervisor. Operator has the ability to

reconfigure the preset zone control buttons, but are not

able to save them.

Lockout Mode 3: Zone control buttons are preset and

locked by supervisor. Operator is restricted to only use

the zone control buttons preset by supervisor.

Entering the Supervisor Control Modes
