PRIOR TO INSTALLATION
Prior to installing the ZER Flushometer, install the
items listed below:
• Closet or urinal fixture
• Drain line
• Water supply line
IMPORTANT:
•ALLPLUMBING ISTOBEINSTALLED INACCORDANCEWITH
APPLICABLECODESAND REGULATIONS.
• WATER SUPPLY LINES MUST BE SIZED TO PROVIDE AN
ADEQUATEVOLUMEOF WATERFOR EACHFIXTURE.
•FLUSHALLWATER LINESPRIORTOOPERATION (SeeStep

•DIRTANDDEBRISCANCAUSE FLUSH VALVETORUNCON-
TINUOUSLY.
The ZER is designed to operate with 20 to 80 psi (138 to 552 kPa) of water pressure. THE MINIMUM PRESSURE REQUIRED TO
THE VALVE IS DETERMINED BY THE TYPE OF FIXTURE SELECTED. Consult fixture manufacturer for pressure requirements.
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.
2.) Prior to inserting the flush valve tailpiece (B) into stop valve,
be certainthat the O-ringseal (C) is locatedinO-ring sealgroove
at the end of the tailpiece and 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.
3.) 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.
4.) 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.
5.) Hand tighten spud nut and vacuum breaker tube nut to fix-
ture and flush valve. Adjust the valve assembly for plumb.
Tighten fixture spud nut, vacuum breaker tube nut and lock nut
with a wrench. Do not turn water on until batteries are in-
serted – see 6.

8.) ADJUSTING YOUR E-Z FLUSH
6.) ACTIVATION
Using supplied battery compartment wrench,
remove battery compartment from the E-Z
Flush™ unit.
Load batteries into compartment tray (note
position of batteries in tray), and reinstall
battery tray into the E-Z Flush unit.
Secure tray with battery compartment wrench. The last three
turns of the wrench will activate the E-Z Flush unit. The E-Z
Flush System is now operational.
Your E-Z Flush unit comes preset from the factory. If special
circumstances require adjustment of the activation distance,
see Appendix A – Adjusting Your E-Z Flush.
The E-Z Flush unit has a 10-minute start-up sequence in which
theObject LockSensor will flashthe User-In-View yellow L.E.D.
continuously as long as a user is in view. After the start-up
sequence is completed and when the Object Lock Sensor has
a user in view, the User-In-View yellow L.E.D. will flash only 3
times after a 5-second delay. This delay prevents needless
flushes when someone walks by. Sensor units should not be
located across from each other or in close proximity to highly
reflective surfaces.

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.) TheZER flush valvesare presetfor fixturevolumeasmarked
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 Distance Adjustment
Screw 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.

vated), or Sensor Range Reset
Button has been depressed.
Batteries need replacing.
Diaphragm damaged or valve
control stop improperly adjusted.
Object Lock Sensor range set too
close to E-Z Flush, batteries are
dead, or water supply is turned off.
Dirt or debris preventing dia-
phragm from functioning properly.
Batteries are dead.
SOLUTION
Remove item covering sensor or adjust
Object Lock Sensor activation distance.
(See Appendix B – Adjusting the E-Z Flush.)
Yellow L.E.D. light will flash only 3
times,acknowledging a user is in view after
the 10-minute start-up mode.
Replace batteries.
Replace diaphragm and/or adjust valve
control stop.
Adjust Object Lock Sensor, replace batter-
ies, or turn water on. If the E-Z Flush does
not begin to function, call Customer Service
at 1-800-997-3876.
Remove dirt or debris, check by-pass hole
in diaphragm.
Replace batteries. If the E-Z Flush does not
begin to function, call Customer Service at
1-800-997-3876.
