Prior to installing the ZER Flushometer, install the
items listed below:
• Closet or urinal xture
• 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 CON-
TINUOUSLY.
Prior to Installation
Sweat Solder Adapter Installation Instructions
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.

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.

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
the Object Lock Sensor will ash 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 ash only 3 times
after a 5-second delay. This delay prevents needless ushes when
someone walks by. Sensor units should not be located across from
each other or in close proximity to highly reective surfaces.
1. USER-IN-VIEW L.E.D.
Yellow light ashes 3 times – after 5-second delay – when a
user is in view. The yellow light ashes constantly when a user
is in view during the 10-minute start-up sequence.
2. OBJECT LOCK SENSOR
3. BATTERY L.E.D.
Red light ashes indicating it is time to replace batteries with 4

Adjusting Your E-Z Flush - Cont.
Before the supply water is turned on, be sure all stop valves
to the ush valves are closed o󰀨 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 o󰀨
at the main supply valve.
Stop Valve
On/O󰀨
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.

hours after the last use.
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 ash 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 ash.
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 ashing. If sensor locks onto door or wall, unit will not ush 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 ash only 3 times when a user is in view (after a 5-second delay).

Wiring Diagram

Gateway Instruction
You can request your Ethernet or LTE gateway by visiting
Zurn.com/plumbsmart-gateway-request
or call Zurn Customer Care at 1-844-987-6737
Step 1. Request Gateway:
Step 2. Cabling, Powering and Connecting Your Device:
1. Connect one end of the RJ45 Ethernet cable (supplied) to the
gateway’s Ethernet port and plug the cable’s other end into the
nearest wall port of the building’s Ethernet network.
2. Connect the power supply to the power jack.
3. Wait for status LED to go from ON to double ash every second,
the LoRa LED to turn ON solid, and the cell LED (if LTE enabled)
to ash once every 3 seconds. Should take around 1-2 minutes
depending on location. Your gateway is now ready to transmit
data from your Zurn connected product.
4. Zurn Gateways have been set to DHCP by default. Please
consult local IT support for possible additional access
requirements for your network.
Step 3. Determining general Location for the Zurn Gateway:
• Select a location central to all devices to be connected to this
gateway. Place the gateway as high as possible, such as near
the top of a wall.
• Avoid obstructions. Thick walls and reective surfaces, such
as metal, weaken the signal between the gateway and other
devices.
• The LoRa antenna is an omni-directional antenna, but for best
results, mount the device so the LoRa antenna is in a vertical
position near the top of a wall. We recommend conducting a site
survey to test the signal strength in di󰀨erent locations before
you mount the device.
Step 4. Mounting the Zurn Gateway:
The device ships with a mounting bracket. You will also need:
• Four #6 screws with anchors
• Screwdriver
• Drill
1. Determine where you want to mount the device.
2. Mark where you want the screws to go.
3. Drill holes for the screws and insert anchors.
4. Place the mounting bracket and secure it with screws.
5. Attach the device to the bracket and rotate to lock into place.

“Device Not Communicang” warning or severe alert posted in
plumbSMART for all devices (> 3 hours)
Step 1
Verify gateway Status LED ashes twice every 2 seconds. If LED
is OFF or ON solid, power cycle the gateway and wait for no
more than 5 minutes for unit to inialize and connect.
Step 2
Aer inializaon is nished, LORA LED should turn ON solid
within an addional minute.
Step 3
If LORA LED does not turn ON solid and ethernet cable
connected, contact facility IT administrator to modify port rules
to allow Zurn gateway to access the internet via local router.
If gateway model is ETH/LTE, visually verify SIM card is installed
in designated slot on the side of gateway. If unit has a SIM card,
then disconnect ethernet cable and power cycle the gateway
and wait for unit to inialize and connect. LORA LED should
turn ON solid aer inializaon.
Step 4
If problem sll present, move gateway closer to LoRa monitors
and/or verify gateway mounng, orientaon and connecons
comply with requirements listed in Zurn Gateway Installaon
