Care and Cleaning Instructions

Gateway Instruction
Register in plumbSMART
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.
NOTE: Instructions below are duplicated from registration card supplied with monitor
1. Install Zurn Connected Product(s)
2. Install Zurn Gateway per the Gateway Instructions Manual
3. Request plumbSMART Administrator Account at 844-987-6737
4. Zurn creates your Enterprise Account for you! (You will be required to identify your building location, number of oors, and number
of rooms.)
5. Log in to plumbsmart.zurn.com
6. Register each Connected Product in plumbSMART (Watch How-To Videos to Get Started. Located in the support section inside the
portal.)
7. Now, Relax. You’re Connected.

To adjust features from default conguration, you must remove the
battery tray. Once battery tray is removed you will see the switches.
Purge Features:
The purge switches can be congured for 4 modes of operation: Disabled (standard conguration), 12 hour, 24 hours, or 48 hours.
Purge water ow duration is 2 minutes. Note: Purge activation occurs every switch selected time (0,12, 24, or 48 hours) after last
activation.
Flow Time:
There are 6 optional time congurations: 30 seconds (standard), 5s, 10s, 15s, 60s, & “Less Time-out”. The “Less Time-out” option
actually ceases water ow (turns o󰀨) after 20 minutes to limit chance of water damage in the event a sink drain becomes blocked .
Sensing Mode (DEFAULT):
During this mode the valve will shut o󰀨 after hands are removed. If hands are not removed the time out delay will turn o󰀨 the faucet (ex:
standard conguration is 30 seconds)) (See Sensing & Metering Mode ow chart above page)
Metering Mode:
When hands are detected by the sensor, water will run for ‘ X’ seconds (standard conguration is 30 seconds) before turning o󰀨. (See
Sensing & Metering Mode ow chart on following page)
Sensor Sensitivity: (Default setting: Low):
There are 4 sensitivity options, which can be selected to achieve the optimal detection performance related to the sink material, shape,
& nish. The faucet sensor sensitivity is congured during pack-out but the mode can be changed upon installation to optimize the
performance within the sink. Sensor sensitivity and sensor detection Modes A & B may be tried for various lighting conditions, sink
materials and shape.
Switch 7 controls the sensitivity
-On (default) is normal sensitivity for most sinks providing max range.
-O󰀨 set the sensor to a lower sensitivity level for sinks that cause false activation. The detection range maybe less for all hands.
Switch 8 controls sensor mode
-On (default) enables the mode that lters the e󰀨ects of owing in the bottom of problematic sinks. Detection maybe less for some
hands.
-O󰀨 disable the lter mode, so detection is expanded deeper into the sink for max detection range for all hands. Some sinks may
only be able to operate in this mode.
NOTE: After a conguration switch change has been made. Disconnect sensor cable from electronics box, wait 30 seconds, then
reconnect sensor cable and wait 30 additional seconds to allow the sensor to tune-in the sink characteristics. Calibration includes
characterizing the sink with water running into the bowl. This could be 5 to 60 seconds depending on conguration.
