PRIOR TO INSTALLATION

Prior to installing the ZER Flushometer, install the items listed below:

• Closet or 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 9).
• DIRT AND DEBRIS CAN CAUSE FLUSH VALVE TO RUN CONTINUOUSLY.

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 supplyescutcheon 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 certain that the O-ring seal (C) is located in O-ring seal groove 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 fixture 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 inserted – see 6.

6.) ACTIVATION
Using supplied battery compartmentwrench,remove battery compartmentfrom the E-Z Flush™ unit.

Load batteries into compartment tray (note position of batteries in tray), and reinstallbattery 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 the Object Lock Sensor will flash the 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.

7.) VISUAL INDICATOR GUIDE

8.) ADJUSTING YOUR E-Z FLUSH

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.

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) without 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, recreation parks, etc.

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 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).

TROUBLE SHOOTING GUIDE

Lock Sensor is covered or Object Lock Sensor is set too far out, registering the opposite wall or door as a user.| Remove item covering sensor or adjust Object Lock Sensor activation distance. (See Appendix B – Adjust- ing the E-Z Flush.)
Yellow L.E.D. light flashes continu- ously when Object Lock Sensor is activated by a user.| E-Z Flush unit is in 10-minute start-up mode (when first activated), or Sensor Range Reset Button has been depressed.| Yellow L.E.D. light will flash only 3 times, acknowledging a user is in view after the 10-minute start-up mode.
Red L.E.D. light flashes.| Batteries need replacing.| Replace batteries.
Not enough water to fixture or too much water to fixture.| Diaphragm damaged or valve control stop improperly adjusted.| Replace diaphragm and/or adjust valve control stop.
Valve will not operate.| Object Lock Sensor range set too close to E-Z Flush, batteries are dead, or water supply is turned off.| Adjust Object Lock Sensor, replace batteries, or turn water on. If the E-Z Flush does not begin to function, call Customer Service at 1-800-997- 3876.
Valve does not shut off.| Dirt or debris preventing diaphragm from functioning properly.| Remove dirt or debris, check by-pass hole in diaphragm.
Valve does not flush even after Object Lock Sensor has been adjusted.| Batteries are dead.| Replace batteries. If the E-Z Flush does not begin to function, call Customer Service at 1-800-997-3876.
