Urinal Flush Valve
Specification
Installation Precautions
1. Prior to Installation
Prior to Installing your TOTO automatic flush valve,
install the items listed bellow:
· Closet fixture/Urinal fixture
· Drain line
· Water supply line
The supply piping to these devices shall be securely
anchored to the building structure to prevent the
installed device from unnecessary movement when
operated by the user. Care shall be exercised when
installing the device to prevent marring the exposed
significant surface.
2. Important
All plumbing is to be installed 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.
The minimum pressure required to the valve is
determined by the type of fixture selected. Consult
fixture manufacturer for pressure requirement.
Do not use toothed tools to install or service the valve.
3. Main dimensions of the piping

4. Use care not to damage the surface of the infrared
sensor.
5. For Toilet Flush Valve
The toilet sensor valve may not function if toilet seat
and/or lid cover are left upright as it may block the
sensor.
6. For Urinal Flush Valve
The automatic flush valve is designed to be used with a
washout urinal for optimum performance. However, a
siphon jet urinal may also be substitutional. Blowout
urinals are not recommended.
7. The detection range of the infrared sensor is shown in
the figure below.
Do not install a handrail or any other object within the
detection zone of the sensor, as object blocking the
sensor may cause the valve to malfunction.
Additionally, to avoid the possibility of valve malfunction,
do not install the flush valve in a location where the
sensor faces a stainless wall, other highly reflective
surface or another infrared sensor.
Refer to local codes for special requirements.
Note
Detection zone
The detection zone is self-adjusting and is equipped with a
3-second flush delay after removal from the detection zone.
(No flush delay for Urinal flush valve)
The detection zone may differ according to color of user’s
clothes.
When a user wears black clothes, the detection zone may
become smaller and the valve may not flush.

Test Run
1. Energize the primary side of the transformer (THU701TR
or THU700TR) For AC Type
2. Make sure the control stop is open.
3. Sit on the toilet seat. (for Toilet flush valve)
Stand within two feet from the front of the flush valve.
(for Urinal flush valve)
4. Stay there for six seconds or more and leave the toilet
seat or the urinal. The valve will automatically flush.
5. Press the manual flushing button and make sure the
valve flushes properly. (for Toilet flush valve)
6. Recheck all the pipe connections for water leaks. If the
flush valve is not operating properly following the test
run consult the Troubleshooting section of the Owner’s
Manual. Recheck installation procedures only after
turning off and locking out breaker for power line
Note to the installer
After the flush valve unit has been installed correctly,
please explain to your customer how to use it and tell him
or her to observe the following instructions.
1. Do not put any object in front of the sensor window
which could obstruct the sensor, causing the flush valve
to malfunction.
2. For troubleshooting, consult the Owner’s Manual.
1 To minimize the risk of electrical shock and fire
hazard, turn off and lock out breaker for power line
before attempting troubleshooting, maintenance,
adjustment or repairs.
2 If you lack the necessary skills required or have
difficulty following the directions for installation,
maintenance, repairs, troubleshooting or
adjustments, of the product, do not proceed without
help from a qualified person to assist you in
performing any of these functions.
Adjustment
WARNING: To minimize the risk of electrical shock and
fire hazard, turn off and lock out breaker for
power line before starting adjustment.
1. Adjustment of the discharge quantity
(1) Remove the front cover.
(2) Adjust the discharge quantity by rotating the screw
on the piston valve.
Wiring
WARNING: To minimize the risk of electrical shock and
fire hazard, turn off and lock out breaker for
power line before starting wiring.
This product must be connected to the type of power
source indicated on the installation instruction. If you are
not sure of the type of power source available, consult
your dealer or local power company.
The wiring diagram is shown below.
When connecting the secondary side of the transformer
to each flush valve, use only UL Class ΙΙ No.18 wires.
- Wiring Diagram -
Installation of the Transformer
WARNING: Whenever installing the transformer or wiring,
turn off and lock out breaker for power line in
order to minimize the risk of electrical shock or
fire hazard.
2. Adjustment of the flow rate
Adjust the flow rate by turning the screw/handle of the
control stop.
Turn the screw/handle to the right to decrease the flow
rate and turn it to the left to increase.
3. Adjustment of the detection range
The detection range of the infrared sensor does not
need to be adjusted because it has been factory-preset.
This automatic flush valve unit requires a special
transformer. When installing the transformer, please
observe the following instruction.
1. The wiring distance from the transformer to the flush
valve must be 45 feet (13.5m) or less.
Use UL class ΙΙ No.18 wire when connecting the flush
valve to the transformer.
2. This transformer can be connected to a maximum of 10
flush valves.
WARNING: Be sure to ground the 4"SQ box to eliminate
the risk of electrical shock or fire hazard.
Never kink or bend primary-side lead wires
and/or secondary-side lead wires of the
transformer when wiring them in the conduit
tube or the junction box altogether.
