Important Safety Information
• 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 xture.
• Flush all water lines prior to making connections.
• Do not use pipe sealant or plumbing grease on any tting other than the control stop inlet.
• Sensor units should not be located across from each other or in close proximity to highly reective surfaces.

1. Measure distance from nished wall to the center line of the xture
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.
NOTE: Before installation, turn o󰀨 water supplies to existing xture and remove ushometer if replacing an existing device.

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 nished wall to rst 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 ush against
nished wall and tighten set screw with hex wrench (supplied) to
secure it in place.
Using a at head screwdriver,
turning counterclockwise, ush
supply line by opening the
control stop. Turning clockwise
will close the control stop.

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 o󰀨 tight by using a athead 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 at head screwdriver and turning the stop valve
adjustment screw counterclockwise.
Allow the water supply line to ush any debris or sediment that
may be present in the line. Close the control stop once the
lines are completely ushed.

Slide the tube nut, spud nut, slip gasket, rubber gasket and
spud escutcheon over the vacuum breaker tube and insert tube
into xture spud. Hand tighten tube nut to valve body and hand
tighten spud nut onto xture spud. Adjust the valve assembly for
plumb. Tighten xture 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 xture. Consult plumbing Codes & Regulations for specic
details.

E-Z Flush Installation
Place the supplied valve gasket onto the unit as shown. Use one
hand to raise the unit to the handle port of the ush valve and use
the other hand to rotate the unit’s valve nut to begin engaging the
threads of the valve body. Use the supplied wrench to tighten the
E-Z Flush unit securely to the valve body.

E-Z Flush Activation
Using supplied hex key, remove battery compartment from the E-Z
Flush unit.
Load the supplied batteries into the battery tray. Note the battery
orientation shown. Reinstall the battery tray into the E-Z Flush unit
using the hex key. The user LED will blink when the unit becomes
powered.
Notes:
Your E-Z Flush unit comes preset from the factory. If special
circumstances require adjustment of the activation distance, see
section of this manual “Adjusting Calibration Distance”.
Each E-Z Flush comes with a 24-hour ush mode that is disabled by
default. To toggle this mode, see the section of this manual entitled
“Toggling 24-Hour Flush Mode”.
Flushing the System
When all ush valves are connected to the xtures and water
pressure is available, it is recommended that the supply piping be
ushed to remove dirt, pipe chips, etc., from system.
Use the following procedure to ush out the supply piping:
1. Remove the main valve body cover.
2. Remove the working parts from the ush valve shown on the right
3. Replace the plastic cover and main body cover without reinstall-
ing the working parts.
4. Open the stop valve by using the stop adjusting screw and ush
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 elds, recreation parks, etc.

The ZER ush valves are preset for xture 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 ush valve for proper operation, gradually adjust the stop
valve open, using the adjusting screw, while actuating the valve
until the rate of water ow into the xture is not excessive, yet
is su󰀩cient to adequately evacuate the waste. The nal setting
for urinals should be such that the xture will not overow when
the valve is actuated in succession. The stop cap screw cover
should be replaced after nal adjustments have been made.

Each E-Z Flush comes calibrated from the factory to work optimally in most restroom environments. In low light or highly reective envi-
ronments however, it may be necessary to adjust the calibration distance of an E-Z Flush unit. To do this, a Zurn Magic Magnet may be
used. To re-calibrate an E-Z Flush with a Magic Magnet, follow the procedure below: comes calibrated from the factory. To re-calibrate
for a specic environment, follow these steps:
1. Stand at the desired calibration distance:
- ~28” from the sensor in a water closet application.
- ~22” from the sensor in a urinal application.
2. Raise the Magic Magnet to the top/bottom (depending on valve orientation - refer to image below) of the unit’s lens until the user LED
lights up.
3. Hold the Magic Magnet in that position until the user LED begins to blink. Remove the magnet and allow the user LED to blink 10 times
while standing in the same position. A quick double-blink signals that the calibration is complete.
4. Test the new calibration distance by walking away from the unit for 5 seconds and returning to the position at which it was calibrated.
Watch for the user LED to blink. If the user LED blinks, the calibration distance has been reset successfully.
Note: In water closet applications, it is a good idea to make sure that the new calibration distance does not allow the sensor to see
the stall door. To check this, exit the stall and close the stall door for 10 seconds. Open the stall door. If the unit does not ush, the
calibration distance is okay. If the unit ushes, you will need to recalibrate to a closer distance.

Each E-Z Flush comes with a 24-hour auto-ush feature that is disabled by default. This feature is intended for low-use applications
where trap seal depletion is a concern. To toggle this feature, follow the procedure below:
1. Raise a Magic Magnet to the top/bottom (depending on valve orientation - refer to image above) until the user LED lights up.
2. Lower the magnet so that the user LED turns o󰀨.
3. Repeat this turn on / turn o󰀨 procedure three more times.
4. After the fourth time, the user LED will display a series of rapid blinks. Three blinks signies that the feature has been toggled on. Six
blinks signies that the feature has been toggled o󰀨.

PROBLEM CAUSE SOLUTION
User LED continuously blinks every
ve seconds.
Low battery life. Replace batteries.
Insu󰀩cient ow of water. Stop Valve improperly adjusted. Adjust stop valve (open).
Excessive ow of water. Stop Valve improperly adjusted. Adjust stop valve (close).
Continuous ow of water. Debris clogging ush valve’s
diaphragm.
Replace diaphragm kit (See section
entitled “Repair Parts”).
User LED does not blink when user is
present.
Calibration distance is set too short.
Conrm by placing hand 6” in front of
the sensor and watching for a blink. If
the user blinks, the calibration is set
too short.
Reset calibration to desired distance
(See section entitled “Adjusting
Calibration Distance”).
Batteries are dead. Conrm by placing
hand 6” in front of the sensor and
watching for a blink. If the user LED
does not blink, the batteries are dead.
Replace batteries.
