B2.) Before the supply water is turned on, be sure all stop valves
are closed off tight. The stop valves can be opened and
closed by using the adjusting screw located at the center of
the stop valve cap. Stop valve adjustments can only be
made by using the adjusting screw. It is not necessary to
remove the stop valve cap when making adjustments. If
for any reason it becomes necessary to remove the stop
valve cap, be certain the water is shut off at the main
supplyvalve.
3.) Prior to inserting the flush valve tailpiece (B) into stop valve
(A), be certain that the O-ring seal (C) is located in O-ring
seal groove at the end of the tailpiece and that the locking
nut (D) and locking snap ring (E) are located as shown.
Care should be taken not to damage the O-ring when in-
serting the tailpiece into the stop valve. If lubrication is
needed, wetting the O-ring with water will be sufficient.
When all stops are connected to the water supply and
water pressure is available, it is recommended that the
supply piping be flushed to remove dirt, metal chips, etc.,
from system.

A. Before the valve is installed, open each stop fully for a
brief time and catch the water in a two gallon or larger
bucket. For multiple installations, start with the stop
valve closest to
the water supply
and work toward
the most remote
valve.
B. Due to the small
passages and
orifices, it is not
possible to
flush the piping
through the low
volume valve.
C. Once the lines
are flushed, the
valve can be
installed.
PRIOR TO INSTALLATION
Prior to installing the HydroVantageTM flushometer valve,
install the items listed below:
• Closet or urinal fixture
• Drain line
• Water supply line
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 water lines prior to operation (See Step 2).
• Dirt and debris can cause flush valve to run continuously.
• Sensor units should not be located across from each other
or in close proximity to highly reflective surfaces.
The HydroVantageTM design is optimized to operate between 35 and 80 psi (241 to 552 kPa) of water pressure(running). The
minimum pressure required for the valve to work properly is determined by the fixture selected. Please consult fixture manufacurer
for pressure requirements. The sensor is designed to operate at light levels as low as 1 lux but for optimum performance a
minimum of 20 lux is recommended. Protect the chrome or special finish of this flushometer. Do not use toothed tools to install
or service the valve.
Important: Do not remove sensor sticker until reading instructions 8a-8d

4.) Insert the flush valve tailpiece (B) into the stop valve (A) and
hand tighten the lock nut (D) to the stop valve. Plumb the
entire unit.
5.) Determine the length of vacuum breaker tube (F) required
to join the flush valve and fixture spud. Cut the vacuum
breaker tube, if required, to this length. Assemble the
vacuum breaker tube assembly and spud nut assembly to
the flush valve and fixture spud.

7.) Determine all flush valve connections are tight and pro-
ceed to fully open the control stop. Use the Manual Over-
ride Button to check for leaks. Proceed to step 8 and read
the important instructions thoroughly.
Important: If stall partitions are to be installed at a later
date here DO NOT proceed to step 8Activation.

Important: Step 8 Valve Activation should only be conducted after all
partitions, paper dispensers, hand rails and other accessories are in
place.
IMPORTANT: READ THOROUGHLYBEFORE REMOVING STICKER.
8) Valve is ready for activation and calibration.
8a) OPEN CONTROL STOP
- If the water begins to flow through the valve when the control stop is opened
it is likely that the solenoid opened during shipment. The solenoid will be closed
at the beginning of the valve calibration.
- For urinal installations it is important that the flow rate into the urinal does not
exceed the flow rate out of the urinal. Test this by holding down the Manual
Override Button for 30 seconds. If necessary reduce the flow rate by closing
the control stop just to the point where the urinal will not overflow.
8b) ACTIVATION
Remove Sticker
Note: If the sticker was removed prior to the completion of the installation, calibra-
tion attempts will be made every 5 minutes.
8c) DETECTION:
All 4 LEDs will flash 3 times within 1 minute indicating that the valve has
sensed bright lights. Calibration will begin in one minute (Fig 8b)
8d) MOVE AWAY FROM THE FRONT OF THE VALVE (step outside of the stall
with the door in the natural position) Fig 8c.
CHARGING:
Flush valve will attempt to charge its power supply (rechargeable cell).
There will be 1-5 flushes initiated depending on the initial power supply state
and running pressure in the facility. At the end of each flush, the LEDs will
display the current level of charge (bottom blue led= 0-25% charge, bottom
blue and green = 26-50% charge, three bottom LEDs (blue, green, green) =
51%-75% charge, all 4 = 76%-100% charge
If for some reason the valve can not achieve a full charge during the first
flush, it will immediately attempt to charge its power supply with another 1-
5 flushes. If it fails a second time, the valve will not attempt to recharge for
another 5 minutes. Every minute the LEDs will display the generator failure
pattern. (green top and blue bottom led) It will repeat an attempt every 5
minutes to charge the power supply until successful. The completion of a
successful charging sequence is signified by the flashing of all 4 led’s from
top to bottom. Once the rechargeable cell is fully charged (100%), the valve
will proceed to calibration of the sensor.
8e) CALIBRATION:
Once the power supply is charged, the valve will attempt to calibrate the
sensor after a one minute delay. It is very important that the installer
does not block the ambient light in the room and does not walk in
front of the sensor during calibration. User should be outside of
stall with the door in the natural position. (Fig 8c)
The valve takes 20 sensor readings. During each reading, it flashes all 4
LEDs from the top to the bottom. (Fig 8d)
AUTOMATIC LIGHTING:
If bathroom is equipped with occupancy sensors, be certain the
lights remain on throughout the entire calibration process.
READY TO GO:
If the sensor calibration passes, the LEDs will turn off, the valve will flush,
and then the valve is ready to go.
If it fails due to the ambient light levels being too low or the valve sensed
someone in front of the valve, it will immediately attempt to re-calibrate the
sensor. Another 20 LED flashes from top to bottom will be seen. The valve
will attempt 3 sensor calibrations. After the third failure, the valve will not
attempt to re-calibrate for another minute. The majority of valves will
calibrate in 5 minutes but depending on lighting conditions it could take up
to 15 minutes. The end of calibration and the valve being ready for use is
signified by two consecutive flushes.

Installation Notes:
For closet applications the sensor may activate if the toilet seat and/or toilet lid are
left in the upright position. See Trouble Shooting Guide at the end of this document
for assistance.
For ADA installations it is recommended to mount the grab bar at the maximum
height of 36” (914mm) or use split grab bars on either side of the flush valve.
The tailpiece length for the HydroVantage Valve to fit a given rough in dimension
differs from other Zurn products. The chart below shows the various tailpiece
lengths available and the corresponding rough in dimensions.

Testing Functionality (Sensor Verification)
oThe valve is looking for the fluctuations in ambient light and infrared reflection
patterns associated with someone using the product for its intended purpose
oThe valve will not respond to waving your hand in front of the sensor
oTo test the valve follow the steps below:
Approach the valve (Urinal) or walk into the stall and stand at the edge of the
bowl or sit facing the valve (Closet) so you can observe the LED activity
Look for the following LED sequence
Single Blue LED (Change in ambient light detected)
5-7 seconds (Closet), 3-4 seconds (Urinal) later a series of 4-5 Blue LED
flashes (User Confirmation)
Green LED flashing (Valve is waiting for occupant to leave in order to
flush)
Optional Interface Software
oThe optional interface software can be loaded onto a laptop PC and used to
communicate with the valve to retrieve activation statistics, estimated water
usage, adjust flow rate, adjust sensor settings, and general trouble shooting.
oIf interested in the interface software and communication cable, please call Zurn

Allen wrench.
2. Gently pull up on the cap to separate the valve cap from the rest of the valve
body.
3. Turn the valve cap 180°.
4. Lower the valve cap back onto the valve body being careful not to pinch any
wires.
5. Gently push the valve cap down until it is fully seated. Excessive force should
not be used any may indicate an interference or a pinched wire which may
damage the electronics.
6. Replace the 2 security screws.
Removing Valve Cap:
1. Remove 2 security screws from either side of valve cap with provided security
Allen wrench.
2. Gently pull up on the cap to separate the valve cap from the rest of the valve
body.
3. Disconnect the 3 electrical connections between the valve cap and the valve
body.
a. RS232 Communication (3 pin Red/White/Black - Wire to Wire)
b. Solenoid (2 pin Red/Blue – Wire to Main PCB)
c. Generator (3 pin Red/Green/Black – Wire to Main PCB)
NOTE: All connections are locking waterproof connectors. The locking tab must
be depressed during disconnection to avoid damage to the connectors. A thin
flat blade screwdriver can be slipped into the connectors on the Main PCB to
gently depress the locking tab to ease disassembly.
Cleaning the Valve
Water and a mild detergent may be used to clean the outside of the
HydroVantage. Harsh chemicals such as chlorine bleach or cleaning agents that
contain ammonium chloride, acid or alkali can damage the surface of the lens.
