• Do not convert or modify this Zurn product. All warranties will be voided.
• 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 making connections.
• Do not use pipe sealant or plumbing grease on any fitting other than the control stop inlet.
• Sensor units should not be located across from each other or in close proximity to highly reflective surfaces.
• Control stop should never be opened to allow flow greater than fixture is capable of evacuating. In the event of valve failure, fixture must be able to handle a continuous flow.

Prior to Installation

• Before installing your Zorn® automatic sensor-equipped flush valve, the items listed below should already be installed on site:
  – Closet or urinal fixture
  – Fixture carrier
  – Drain line
  – Water supply line

Package Contents

Sweat Solder Adapter Installation Instructions
NOTE: Before installation, turn off water supplies to existing fixture and remove flushometer if replacing an existing device.

1. Measure distance from finished wall to the center line of the fixture spud. If necessary, cut water supply pipe 1-1/4” shorter than this measurement. Deburr by chamfering O.D. and I.D of end of water supply pipe.
   

2. Slide threaded sweat solder adapter onto water supply pipe until shoulder stops on end of pipe. Then sweat-solder the adapter to water supply pipe.
   

3. Measure distance from finished wall to first thread of sweat solder adapter. If necessary, cut chrome cover tube this length.
   

4. Slide wall escutcheon over chrome cover tube and slide both items over water supply pipe. Press wall escutcheon flush against finished wall and tighten set screw with hex wrench (supplied) to secure it in place.
   

Control Stop Installation Instructions

1. Install control stop assembly by threading it onto water supply pipe and tightening with a smooth jawed wrench. Apply thread sealing compound or pipe tape to male NPT thread on sweat solder adapter only.
   Prior to turning on main water supply line ensure all stop valves are closed off tight by using a flathead screwdriver and turning the stop valve adjustment screw clockwise.
   

2. When all stop valves are properly connected to the water supply line and water pressure is available, open the control stop using a flat head screwdriver and turning the stop valve adjustment screw counterclockwise. Allow the water supply line to flush any debris or sediment that may be present in the line. Close the control stop once the lines are completely flushed.
   

Flush Valve Installation Instructions

Prior to attaching flush valve tailpiece to control stop, inspect and verify that the O-ring seal is located within the O-ring groove at the tailpiece. Ensure that the locking nut and locking snap ring are also present on the tailpiece.
Lubricate O-ring with water if necessary and insert flush valve tailpiece into the control stop valve. Tighten locking nut using a smooth jawed wrench.
Vacuum Breaker & Flush Connection Installation Instructions

Determine the length of vacuum breaker tube required to join the flush valve and fixture spud, and cut if necessary.
Slide the tube nut, spud nut, slip gasket, rubber gasket and spud escutcheon over the vacuum breaker tube and insert tube into fixture spud. Hand tighten tube nut to valve body and hand tighten spud nut onto fixture spud. Adjust the valve assembly for plumb. Tighten fixture spud nut, vacuum breaker tube nut and locking nut with a wrench.
Adjust and plumb the valve assembly. Tighten all connections with smooth jawed wrench and turn on water supply at the control stop.
DO NOT cut vacuum breaker tube shorter than 6” below the -C-L- indicator mark, as vacuum breaker must be 6” above the fixture. Consult plumbing Codes & Regulations for specific details.

EZ Flush Installation Instructions

Mount actuator and collar gasket onto handle port hole as shown. Use supplied wrench to secure the handle nut to body tighten clock-wise.

EZ Flush Activation Instruction
Using supplied hex wrench,remove battery compartment from the EZ Flush™ unit.
Load batteries into compartment tray and reinstall battery tray into the EZ Flush unit. See position of batteries on the left. If installed incorrectly, valve will not work and LED will blink once every 5 seconds.
Secure tray with hex key. The last three turns of the wrench will activate the EZ Flush unit. The EZ Flush System is now operational.
Your EZ Flush unit comes preset from the factory. If special circumstances require adjustment of the activation distance, see Appendix A – Adjusting Your EZ Flush.

Visual Indicator Guide

1. Initialization / Power up
   Lights up for 1 sec on first time startup.

2. Target Detection
   3 blinks while detecting, then a double blink indicating target qualified. It will continue to double blink every 30 seconds if target remains present. After target is no longer detected, Flush will flush after 2 seconds.

3. Low Battery / Batteries Orientation Incorrect
   1 blink every 5 seconds.

Maintaining Your EZ 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, behind the stop valve 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.

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:

1. Remove the main valve body cover.
2. Remove the working parts from the flush valve shown on the right
3. Replace the plastic cover and main body cover without reinstalling the working parts.
4. Open the stop valve by using the stop adjusting screw and flush out all debris from pipe and connections.
5. 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.

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.

Customized Sensor Range Setting

Unit comes calibrated from the factory. To re-calibrate for a specific environment, follow these steps:

1. While standing next to (not directly in front of) the unit, hold a large and flat, nonreflective object (e.g. white sheet of paper) in front of lens at desired calibration distance (12”-60”).
2. Hold a Zurn Magic Magnet at the position shown below and observe the LED light for up 5 seconds and begin to blink once every half a second.
3. When blinking begins, remove magnet. After a double blink. This signals that the unit has been re-calibrated.
