WATER FIREFLY INSTALLATION PREPARATION
Installation Overview - Sensor End
1. Install the optical sensor. (See instructions “Installing the Optical Sensor”).
2. Program the FIREFLY MIU (See instructions “Programming the FIREFLY MIU”).
3. Choose a method and mount the FIREFLY MIU.
4. Verify that the FIREFLY MIU is transmitting properly.
Installation Considerations
1. Signal distance varies depending on the location of the MIU. FIREFLYs installed
above ground generally transmit the greatest distance.
2. The material of a pit or vault lid affects the transmission range. For example, a
transmitter has a greater range sending from a pit with a plastic lid than a cast iron lid.
3. Lids with holes of a diameter of one inch make possible the mounting of the
FIREFLY MIU through the lid. This can increase transmission range significantly.
4. Complete field installation of an MIU takes 5-10 minutes, depending on the meter
location, and mounting application.
5. If the lid has a hole for the unit, use the cap and wing nut assembly (lid lock). Make
sure there is enough space between the box lid and the ground for the unit to sit. If
not, remove some of the dirt from the bottom of the box. Do not over-tighten lid
locks.
Installation Tips
Following are tips for FIREFLY installation that ensure maximum adhesion.
1. Use only 99% Isopropyl alcohol to prepare the meter face.
2. The most important part of installing a FIREFLY sensor on a clean register is the
Pressure step.
3. Make sure the lens is clean and dry as condensation reduces adhesion.
4. Cool weather may reduce adhesion. Avoid installing sensors in temperatures lower
than 32F.
5. Only use the specified 3M adhesive disks to adhere the sensor to the meter face.
6. Do not to touch the 3M adhesive with bare hands, as skin oil greatly decreases
adhesion.
7. Adhesion is greatly degraded if the sensor is removed from the meter face then
repositioned.
8. Loctite adhesive forms a barrier around the 3M adhesive for the 24-hour curing time.
9. Avoid handling or moving the sensor after placement while mounting the FIREFLY.

FIREFLY INSTALLATION
INSTALLING THE OPTICAL SENSOR
MIU Preparation
1. Survey the meter, checking lid, hole depth, and overall cleanliness.
2. Remove meter box lid.
3. Clean excess dirt from meter lid, exposing meter number.
4. Flip lid back and pre-clean meter face / lens using Fast Orange non-pumice cleaner
and a cloth or cotton swab to remove residue.
5. Clean meter face / lens with an isopropyl alcohol and a NEW lint-free cotton swab.
Note: Use Isopropyl rubbing alcohol, 99% by volume, for best results. Lower
concentrations do not clean as well and may adversely affect the sensor-to-meter
bond.
6. Re-wipe the surface of the meter lens with a clean, new cotton swab each time
until the swab comes up clean, and the clean lens squeaks when wiped.
7. After cleaning, ensure that the lens is completely dry; allow the alcohol time to
evaporate.
MIU Placement
8. Remove the adhesive backing from the high-bond tape on the Optic Sensor face.
9. Refer to Meter Qualification Data in Appendix C to determine sensor placement for
the brand and model of register.
10. Orient the sensor so the water meter needle approaches the sensor from the cable side
and perpendicular to the cable. There are indents on each side of the sensor base
which are to be in line with the needle when it passes.
11. Attach the sensor to the water meter lens surface.

12. Since the 3M tape provides a pressure sensitive seal, the installer should apply
pressure to the MIU sensor immediately after attaching to the lens surface. The
installer should apply four, five-second pushes to the MIU.
TIP: Palm the sensor
and lean onto it to
apply appropriate
pressure.
13. A full cure on the seal is achieved in 24 hours. The sensor should not be touched,
pulled, moved, or handled in any way during this period.
Apply approved adhesive around sensor to seal completely if the pit may fill with
water prior to the 24-hour cure time, or if the meter face is curved and not flat.
Note: If the sensor is initially misplaced, do not attempt to remove the sensor by
twisting the sensor body. A fully cured sensor requires breaking the seal at the
adhesive tape joint with a flat tool such as a screwdriver. Insert the screwdriver
between the aluminum base and meter lens and twist.
14. Mount the FIREFLY MIU to an appropriate wall, stake or through hole in meter
box/vault lid.
If using a stake, affix the stake in the ground adjacent to the meter register. The
platform area of the pole should be facing inward.
Position the transmitter on the pole platform.
Attach the transmitter to the pole with the binding material.
Re-mounting the 3M sensor
For instructions on re-mounting the FIREFLY sensor once placed on the meter, see
Appendix D: Reference, in the section titled “Re-application of Sensor 3M Tape”.

Chapter 2: Installation
INSTALLING THE WIRE-END FIREFLY
1. Refer to Appendix C : Meter Qualification to determine wire connection for the brand
and model of meter.
2. Connect FIREFLY Wire-end to meter contacts using Posi-lock connector or Gel caps.
3. Use 3M mastic pads to cover the wire connections. Make sure mastic pad forms a
complete seal around the wire connections.
4. Mount the FIREFLY to an appropriate wall, stake, or through hold in the meter box /
vault lid.
If using a stake, affix the stake in the ground adjacent to the meter register. The
platform area of the pole should be facing inward.
Position the transmitter on the pole platform.
5. Position the FIREFLY MIU with the threaded neck pointing up.
6. Attach the transmitter to the pole with the binding material.
Note: Do not connect
a multi-meter, probe
or other interrogating
device to the
FIREFLY wires.
Doing so can cause
the unit to globally
reset, erasing all
programmed data!
