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.

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.

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.

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.

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.

INPUT:120VAC,60Hz, OUTPUT:10VDC,1.95A or
THU700TR, INPUT:24VAC,60Hz, OUTPUT:10VDC,1.95A)
according the instructions given later in the “Installation of
the Transformer” section of this manual, mount the
junction box on a pillar or the like, and guide the two lead
wires from the secondary side (10VDC) of the transformer
to the junction box. Also guide the lead wires for multiple
junction boxes.

This automatic flush valve unit requires a special
transformer. When installing the transformer, please
observe the following instruction.

For the left water supply
Before installing the cable, the bracket should be
reinstalled to the opposit direction.
( C , and also see Step 1)
Original
for the right water supply

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.

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.

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.

Adjustment
Step 12
Open the control stop.
Do not proceed to step 13 until all water leaks are
eliminated by tightening all the pipe connections. Failure to
correct all water leaks prior to use may increase the risk of
electrical shock, fire hazard or damage to the product.

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.

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.
