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.

SPECIFICATIONS
* Water pressures over 80 psi are not recommended for most plumbing fixtures.
The type of fixture determines the minimum pressure required for the valve. Consult fixture
manufacturer for the pressure requirement. TET6LB, TET6GB and TET6UB require 24" OR
LONGER vacuum breakers. The valve will not have the proper detection range if you use a
shorter vacuum breaker.

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.
Except for TET6GB, TET6UB and TET6LB, install the Flush Valve so the control stop is
no less than 11-1/8” (282 mm) above the top of the bowl. For TET6GB, TET6UB and
TET6LB, install the Flush Valve such the control stop is 27” (685.8 mm) above the bowl.
see local codes for special requirements.
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.16.
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.

INSTALLATION PROCEDURE
1. Install the control stop using an
appropriate size escutcheon and a
sweat solder adapter kit, if applicable.
Thread sealing compounds should be
used on male NPT threads only.
The distance from center of the
control stop to center of the toilet
should fall within 4-1/4" to 5-1/4"
(107 mm to 133 mm).
For use with a left water supply, attach
the sensor top cover in the opposite
direction so that the sensor will be at
the front.
2. Determine the length of vacuum
breaker tube to join the Flush Valve and
fixture spud. If required, cut the vacuum
breaker tube to the proper length.
3. Assemble the spud nut assembly to the
fixture spud. Hand tighten spud nut to
fixture.
NOTE: For retrofit installation, remove the old Flush Valve
after shutting off the control stop.
NOTE: For reclaimed water, do not use standard vacuum
breaker or control stop.
NOTE: Do not use petroleum based products or pipe
sealants.
