Before the supply water is turned on, be sure all stop valves to
the flush 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
(T)
, behind the adjusting screw
cover if already installed. 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 supply valve.
10.)
The ZER flush valves are preset for fixture volume as marked
on the valve cartons. The valve does not require regulation for
variation in water pressure within its operating range. To set
the flush valve for proper operation, gradually adjust the stop
valve open, using the adjusting screw, while actuating the valve
until the rate of water flow into the fixture is not excessive, yet is
sufficient to adequately evacuate the waste. The final setting for
urinals should be such that the fixture will not overflow when the
valve is actuated in succession. The stop cap screw cover
should be replaced after final adjustments have been made.
APPENDIX A
TO CHANGE ACTIVATION DISTANCE FOR
THE OBJECT LOCK SENSOR
1. Remove battery compartment tray as shown in Step 6.
2. Remove cover and sensor adjustor tool as shown in Step 6.
3. Replace battery compartment in E-Z Flush to activate unit.
4. Press sensor range reset button (the yellow L.E.D. will flash
continuously when it has an object in view for the 10-minute
reset period).
5. Stand at desired activation distance.
6. Use sensor adjustor tool and turn

all the way down and then turn slowly up until
yellow
L.E.D.
begins to flash.
7. Ensure Object Lock Sensor is not detecting stall door or wall
by closing door, stepping out of sensor path and making sure
yellow L.E.D.
is not flashing. If sensor locks onto door or wall,
unit will not flush properly. Shorten activation distance.
8. Remove battery compartment, replace sensor adjustor tool
and cover. Replace battery compartment tray to reactivate E-Z
Flush unit.
9. After 10-minute start-up sequence, the
yellow L.E.D.
will flash
only 3 times when a user is in view (after a 5-second delay).
9.)
When all flush valves are connected to the fixtures and
water pressure is available, it is recommended that the supply
piping be flushed to remove dirt, pipe chips, etc., from system.
Use the following procedure to flush out the supply piping:
A. Remove the main valve body cover .
(O)
B. Remove the working parts from the flush valve
(P)
and
(Q)
(shown in 9b).
C. Replace the plastic cover
(P)
and main body cover
(O)
with-
out reinstalling the working parts.
D. Open the stop valve by using the stop adjusting screw and
flush out all debris from pipe and connections.
E. Shut stop, open cover, reinstall the working parts, replace
both covers and tighten.
This procedure should also be repeated when the system is
drained for seasonal use, as occurs in athletic fields, recre-
ation parks, etc.
