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 120 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 initiate the auto-calibration mode.
Calibration is accomplished as follows.
1. Place the Zurn “Magic Magnet”
(N)
on the front of the valve
as shown in Figure 11 and moved around slightly 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.

LOW BATTERY WARNING
The LED will double flash every 30 seconds when the bat-
teries 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.

FILTER
When accessing filter, be certain the stop valve is closed
at adjusting screw (S) Figure 8
.
The filter is in the end of the tailpiece (see Figure 10). To
remove it for cleaning or inspection, loosen the locknut
completely
(D)
and loosen tube nut
(H)
one turn. Swivel
the valve and remove the filter. It can be cleaned using
water and a brush. When reinstalling, the filter should snap
into the tailpiece securely.

Care and maintenance
Do not pressure wash any flush valve containing electron-
ics. Water and soap blown through seals at high pressure
will damage electronics. Clean valves only with mild
antibacterial soap and water using a soft cloth to clean and
dry the exterior. Do not use cleaners containing abrasives
or chlorine compounds (especially ammonium chloride) to
clean flush valves beacause they will damage the chrome
plated and plastic (lens) surfaces.
