HOW THE MACHINE WORKS
Conventional Scrubbing:
Water and detergent from the solution tank flow to the
floor through a manually controlled solution valve. The
pad uses the detergent and water solution to scrub the
floor clean. As the machine moves forward, the
squeegee wipes the dirty solution from the floor into
the recovery tank.
ec- H2O Scrubbing (ec- H2O Model):
(ec--H2O--electrically converted water)
Normal water passes through a module where it is
oxygenated and charged with an electric current. The
electrically converted water changes into a blended
acidic and alkaline solution forming a neutral pH
cleaner. The converted water attacks the dirt, breaks it
into smaller particles, and pulls it off the floor surface
allowing the machine to easily scrub away the
suspended soil. The converted water then returns to
normal water in the recovery tank.

OPERATION
Tennant T3 Orbital (12--2012) 9
PAD INFORMATION
BACKER PAD (With Retaining Strips)
For best cleaning performance and to avoid damaging
the pad driver plate or floor surface, always use
