into the hinge hole. ( A )
Slide the cable casing into the opening of the bracket. ( B )
Make sure the rod of the flush valve is thrusted when the
button is pushed.

For Toilet flush valve

Before installing the cable, the bracket should be
reinstalled to the opposit direction.

( C , and also see Step 1)

For the left water supply

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

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:  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.

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 -

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.
