Installation Procedure
Note
1. For left water supply, attach the sensor top cover in the
opposite direction so that the sensor will be at the front.
2. For retrofit installation, remove the old flush valve after
shutting off the control stop.

Step 1 (For New Installation)
Install the control stop using a proper size escutcheon and
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 flush
valve should fall within 4-1/4" to 5-1/4"(107mm to 133mm).

Step 2
Determine the length of vacuum breaker tube to join the
flush valve and fixture spud. Cut the vacuum breaker tube,
if required, to the proper length. Assemble the spud nut
assembly to the fixture spud. Hand tighten spud nut to
fixture.

Step 3
Prior to inserting the flush valve tailpiece into the control stop,
be certain that the O-ring is in the groove at the end of the
tailpiece, the locking nut and the snap ring are located as
shown. Connect the flush valve with the control stop and the
vacuum breaker tube. Care should be taken not to damage the
O-ring when inserting the tailpiece into the control stop.
If lubrication is needed, wetting the O-ring with water will be
sufficient. Align the flush valve and securely tighten fixture spud
nut, vacuum breaker tube nut and locking nut with a wrench.

Step 7
Before the supply water is turned on, be sure all water
leaks are eliminated by tightening all the pipe connections.
If for any reason it becomes necessary to remove the
control stop , be certain the water is shut off at the main
supply valve.

Step 8
The flush valves are preset for fixture volume as marked
on the valve carton. The valve does not require adjustment
for variation in water pressure within its operating range.
To set the flush valve for proper operation, open the
control stop completely by using the adjusting screw and
flush the flush valve several times. Gradually adjust the
control stop closed, using the adjusting screw, so that the
rate of water flow into the fixture is not excessive, yet is
sufficient to adequately evacuate the waste. The cap for
the control stop should be placed after final adjustments
have been made. Tighten the cap firmly with a wrench.

Test Run
1. Make sure the control stop is open.
2. Sit on the toilet seat. (for Toilet flush valve)
Stand within two feet from the front of the flush valve.
(for Urinal flush valve)
3. Stay there for 6 seconds or more and then leave the
toilet seat or the urinal. The valve will automatically flush.
4. Press the manual flushing button and make sure the
valve flushes properly and the sensor red light is on for
2 seconds.
5. 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.

Note to the installer
After the flush valve unit has been installed correctly,
please explain to your customer how to use it and tell them
to observe the following instructions.
1. Do not put any object in front of the sensor window
which could obstruct the sensor, causing it to
malfunction.
2. For troubleshooting, consult the Owner's Manual.
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
1. Adjustment of the discharge quantity
(1) Remove the sensor top cover.
(2) Adjust the discharge quantity by rotating the screw
on the piston valve.
To increase
To decrease
2. Adjustment of the flow rate
Adjust the flow rate by turning the screw of the control
stop.
Turn the screw 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.
