10.) 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 10 times to indicate magnet is in the
proper position. Hold magnet in place until 10 flashing lights
occur and the red light turns solid. The solid red light indi-
cates the electronics are in calibration mode.
3. Remove the magnet and stand in front of sensor about 24”
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.

11.) FILTER
When accessing filter, be certain the stop valve is closed
at adjusting screw (S) Figure 10.
Activate valve to relieve internal water pressure and to en-
sure stop valve is closed properly. 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.
