COMMON TOOLS NEEDED
INITIALIZING THE ECOPOWER PRODUCT
FEATURES
Thank you for choosing the latest innovation in low power consumption EcoPower products.
Please note below the duration of time required to initialize the electronics.
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 3 seconds. No manual operation is
required, improving the experience of use and hygiene of the fixture.
Courtesy Flush
When the fixture is not used for 24 hours 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
The EcoPower Flush Valve offers consecutive flush prevention to save water. After a flush, the
valve will not automatically flush again for 30 seconds.
Adjustable wrench Offset pipe wrenchScrewdrivers (Phillips and Flat head)

It will take approximately 5 minutes after connecting the battery for the electronics to
initialize.
This delay is a normal part of startup.
After approximately 30 seconds, the sensor LED will start flashing in 4 second intervals
until the initialization is complete.
TOTO EcoPower Flush Valves are designed to work for 10 years, under normal conditions,
with no minimum daily usage required.

TECHNICAL INFORMATION
WARNINGS
About TOTO's Hydropowered Generator
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.
Please read and adhere to these notes. Failure to do so could result in personal injury
and/or property damage.
Never splash water on the controller. The EcoPower Flush Valve is an electric appliance.
Risk of product malfunction.
Do not strike or kick the EcoPower Flush Valve. Risk of product malfunction or water
leakage.
Do not use the EcoPower Flush Valve at temperatures exceeding what local codes or
product specification allow. Risk of product malfunction.
Do not place an item in a room with high humidity such as shower area or sauna. Risk of
product malfunction.
Never attempt to disassemble, reassemble, repair or modify the EcoPower Flush Valve
unless you are a professional. Risk of product malfunction and electric shock.
Do not use standard vacuum breaker or control stop with reclaimed water flush valve.
Do not use petroleum based products or pipe sealants, doing so could damage product
and cause water damage.
Use appropriate protective equipment such as gloves during installation or maintenance.

BEFORE INSTALLATION
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.
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’ .
Prior to installing your Flush Valve, install the items listed below:
Toilet bowl 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.
The toilet Flush Valve may not function if toilet seat or lid cover are left upright and block
the sensor.
For Reclaimed Water Flush Valve:
Only use reclaimed water angle stop and vacuum breaker.
The detection range of the infrared sensor is shown on p.20.
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.

adapter on the water supply pipe.
3. Attach the control stop to the pipe.
4. Bore a guide hole for the flush pipe
into the wall.
For use with a left water supply,
detach the controller and remount it
to opposite side of valve body.
5. Fasten the base frame to the studs with
four screws (prepared on site) after
adjusting it. ( A )
6. Secure the box with four screws in the
adjustable plate. ( B )

7. Pass the flush pipe and the
vacuum breaker through the
guide hole (Step 4) and
mount them on the bowl.
8. If required, cut the vacuum
breaker tube to the proper
length.
10. Connect the Flush Valve to the control stop
and vacuum breaker tube.
NOTE: Exercise care to avoid damaging the
o-ring when inserting the tailpiece
into the control stop. If lubrication is
needed, wetting the o-ring with water
is sufficient.
9. Make sure that the o-ring fits in the groove
at the end of the Flush Valve tailpiece.

INSTALLATION PROCEDURE — LARGE COVER
11. Connect the battery cable with the controller
and set the battery in place.
The Flush Valves are preset for flush volume
as marked on the valve carton. The valve
does not require adjustment for variation in
water pressure within its operating range.
15. To set the Flush Valve for proper operation,
open the control stop completely and
activate the Flush Valve several times.
16. In the case of excessive flow rate because
of high water pressure, gradually adjust the
control stop clockwise (towards the closed
position) until there is suitable water flow
into the fixture.
NOTE: Adjust so water amount is not
excessive and waste can flow
properly.
12. Connect the cables of infrared sensor and
controller with the connection cable.
13. Connect the cables of manual button and
controller with the connection cable.
NOTE: It will take 5 minutes after connecting the
battery for the electronics to initialize.
After approximately 30 seconds, the
sensor LED will flash in 4 second intervals
until the initialization completes.
14. Ensure all pipe connections are completely
tightened to prevent leaking.
NOTE: If for any reason it becomes necessary to
remove the control stop make sure the
water is shut off at the main supply valve.
NOTE:
The control stop should never be
opened to the point where the flow
from the Flush Valve exceeds the
flow capability of the fixture. In case
of a valve failure, the water must
NOT overflow from fixture.
17. Tighten the front cover screws into the
base frame firmly with the hex wrench.
Make sure no cord, wire or chain is
caught between the front cover and base
frame.
