FEATURES
Fully Automatic and Hygienic
The EcoPower Flush Valve uses an infrared sensor to detect the user using and departing the
fixture, to provide an automatic flush of the fixture after a short delay. No manual operation is
required, improving the experience of use and hygiene of the fixture.
System Protection Timer
When the fixture is not used for 24 hours (12 hours for TEU1LA(R)(X) and TEU1UA(R)(X)) the
protection timer commands the system to flush in order to maintain the trap seal.
Manual Functionality
For maintenance and emergency use, the EcoPower Flush Valve is equipped with a manual
flushing button.
Green Features
Conserves Power
The flushing of the fixture activates a hydropower generator which generates electric power for
the next flush. (See About TOTO’s Hydropower Generator, page 5)
Conserves Water
Two functions help the EcoPower Flush Valve conserve water:
Fuzzy Logic Control
The EcoPower Flush Valve can sense how often and how long the fixture has been used to
deliver the correct amount of water. (See About Fuzzy Logic Control, page 5)
Anti Consecutive Flushing
The EcoPower Flush Valve offers water saving consecutive flush prevention. After a flush, the
valve will not automatically flush again for 10 seconds for urinals and 30 seconds for toilets.
COMMON TOOLS NEEDED
TOTO EcoPower Flush Valve are designed to work for 10 years, under normal conditions, with no
minimum usage required.

TECHNICAL INFORMATION
The flow of water causes the turbine in the power generator to rotate. This process generates
electric power and enables the automatic Flush Valve to operate. See ill. 1 below.
The Fuzzy Logic Control function automatically adjusts the discharge of water according to the
frequency and duration of usage (see ill. 2 and ill. 3).
Typical
Typical
If the idle time is short, the system assumes frequent use
and the Flush Valve discharges less water.
Examples of high frequency use would be during a lunch
break or an intermission in a movie theatre.
A short duration of use
indicates there may be
less to flush, requiring the
Flush Valve to discharge
less flush water.
If the idle time is long, the system
assumes infrequent use, causing the
Flush Valve deliver a typical quantity of
water for thorough flushing.
Examples of low frequency use would be
during after hours at the office or a slow
day at the park.
The Fuzzy Logic
Control system judges
the frequency of
usage by the idle time
of the fixture and
causes the Flush Valve
to discharge water in
an optimal flushing
pattern.
The Fuzzy Logic Control
system predicts the
quantity of flush water
needed based on the
user's duration of use.
A long duration of use indicates
there may be more to flush,
requiring the Flush Valve to
deliver a typical quantity of flush
water for thorough flushing.

IMPORTANT: Plumbing installation must be in accordance with applicable codes and
regulations. Water supply lines must be sized to provide an adequate volume of water for
each fixture. Flush all waterlines prior to operation.
Prior to installing your Flush Valve, install the items listed below:
Bowl fixture/Urinal fixture
Drain line
Water supply line
The supply piping to these devices must be securely anchored to the building structure to
prevent the installed device moving during use. Prevent marring to the exposed surface
during installation. IMPORTANT: Purge all air from the supply lines before connecting
flush valve to the bowl. Trapped air in supply lines may crack the china.
Avoid damaging the surface of the infrared sensor while unpacking.
For Toilet Flush Valve:
The toilet Flush Valve may not function if toilet seat or lid cover are left upright and block the
sensor.
For Urinal Flush Valve:
The urinal Flush Valve is designed for optimal performance with a washout urinal, but a
siphon jet urinal may be substituted. Blowout urinals are not recommended.
The detection range of the infrared sensor is shown on p.15.
To prevent valve malfunction, do not install a handrail or any other object within the detection
range of the sensor. Do not install the Flush Valve where sensor faces a mirror, stainless steel
wall, other highly reflective surfaces or another infrared sensor.
For Reclaimed Water Flush Valve:
Only use reclaimed water angle stop and vacuum breaker.
Toilet and urinal Flush Valves are not interchangeable, check the model number on the label to
make sure you have the correct type. Toilet Flush Valve model numbers begin with ‘TET’ and
Urinal Flush Valve model numbers begin with ‘TEU’.
Except for TET6GAR, TET6UA(R)(X) and TET6LA(R)(X), install the Flush Valve so the control
stop is no less than 11-1/8” (282mm) above the top of the bowl/urinal. For TET6GAR,
TET6UA(R)(X) and TET6LA(R)(X), install the Flush Valve such the control stop is 27” (685.8mm)
above the bowl/urinal. see local codes for special requirements.
