ZEG6003EV Flushometer for
Z5798 Low Flow Urinal
Sensor-Operated, Battery-Powered
Urinal System

PRIOR TO INSTALLATION
Prior to installing the ZEG EcoVantage urinal flushometer
valve, install the items listed below:
• 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 ZEG is designed to operate with 20 to 80 psi (138 to 552 kPa) of water pressure. Protect the chrome or special finish of
this flushometer. Do not use toothed tools to install or service the valve.
1.) Install stop valve assembly (A) using proper size supply
escutcheon and sweat solder adapter kit if applicable.
Thread sealing compounds should be used on male NPT
threads only.
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
inserting the tailpiece into the stop valve. If lubrication is
needed, wetting the O-ring with water will be sufficient.

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 (S) located at the center of the
stop valve cap (T). Stop valve adjustments can only be made
by using the adjusting screw (S). It is not necessary to re-
move the stop valve cap (T) when making adjustments. If
for any reason it becomes necessary to remove the stop
valve cap (T), be certain the water is shut off at the main
supplyvalve.

2.) 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
tothe watersupply 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.

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.
6.) Hand tighten spud nut (G) and vacuum breaker tube nut
(H) to fixture and flush valve.Adjust the valve assembly for
plumb. Tighten fixture spud nut (G), vacuum breaker tube
nut (H) and lock nut (D) with a wrench. Do not turn water on
until batteries are inserted – see 7.

7.)ACTIVATION
Using the 5/64"Allen wrench supplied with the valve, remove
the two 6-32 button head screws holding the top cover in
place. Be sure to place the screws somewhere safe so
they don’t get lost.
Remove the top cover carefully and disconnect the solenoid
wire connector (J). The cover and battery case can now be
takento an appropiate work area to installtheAAcell batteries
provided.
Load the four heavy duty AA alkaline batteries following the
battery orientation guide on the battery box. Note that the coil
springs always contact the flat (negative) end of the battery.
Secure the battery case lid and gasket with screw provided.
Place the battery box into the valve housing, and reconnect
the solenoid wire connector (J). Secure the top cover to the
valve housing using the original screws.
Once this is completed, remove and discard the protective
label (L) from in front of the lens.
Normal valve operation will occur when the valve senses an
object (person). The LED will blink brightly once and then
dimly three times about a second apart. There will be a
pause and then a double blink. At that point the valve is
charged. When object leaves view of the sensor, valve will
activate. This six second sensing cycle will prevent the
valve from flushing needlessly when someone walks by.
If special circumstances require adjustment of the sensing
distance, see Appendix A - Changing Activation Distance.

8.) The ZEG urinal valve comes preset for both flow volume
and sensing distance. Each valve is operated at the fac-
tory using water to insure proper function before being
packed for shipment. The valve does not require water
pressure regulation for variation in water pressure within
the specified pressure range (20 psi to 80 psi) due to
internal pressure regulation.
Open the stop valve to wide open position using the ad-
justing screw (S) on the front of the stop valve. The water
volume will never have to be adjusted with the stop valve
as on some conventional urinal installations.
Install vandal resistant stop cover to complete the installa-
tion.
APPENDIX A
TO CHANGE ACTIVATION DISTANCE FOR
THE OBJECT LOCK SENSOR
The valve does not have to be disabled in any way to change
the detection range. Included with each valve is a Zurn “Magic
Magnet” that is used to intiate the auto-calibration mode.
Calibration is accomplished as follows.
1. Place the Zurn “Magic Magnet” (N) on the left hand side of
the flat top surface of the valve and move around until the LED
comes on.
2. The LED will blink once brightly, then nine times dimly, then
a final bright flash. A solid red light will appear in the sensor
eye. This means the electronics are ready to calibrate.
3. Remove the magnet and stand in front of sensor about 20”
away for the rest of the calibration. The calibration process
takes about 60 seconds. Do not move during this process.
4. When calibration is completed the solid red light will dis-
appear and the LED will blink twice brightly.
8
9.) LOWBATTERYWARNING
The LED will double flash every fifteen seconds when the
batteries reach a predetermined depletion level. There
are approximately five hundred more flushes available
once the LED starts flashing, at which time the valve will
stop operating. The LED will continue the flash sequence
until the batteries are replaced.

10.) FILTER
When accessing filter, be certain the stop valve is closed
at adjusting screw (S) Figure 8.
The filter is accessible from the bottom of the valve using a
slot head screw driver. The filter will come out with the
plug and can be cleaned with water and a soft brush.
When replacing be sure o-ring (M) is in place and undam-
aged.
