receive a RF message.

Installation Considerations

1. Signal distance varies depending on the location of the MIU.

FIREFLY

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.

Two out of three need to be between 32 and 96. Status will display as Success or Failed. Sensor Flap Within each case of FIREFLYs, 24 rubber Sensor Flaps are included for every installation. Utilizing these Sensor Flaps insures a stable environment during the calibration process. Sensor Placement 1.

Apply approved adhesive around the sensor to seal it completely if the pit fills with water prior to the 24 - 96 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.

Chapter 2: FIREFLY Installation 7 Note: The FIREFLY requires 240VAC during programming for the settings to be written to its memory. 7. Power the meter with 240VAC or power the FIREFLY using between 5 and 12 volts applied to the external battery jack. 8. Zero out the register. MODIFICATIONS The Federal Communications Commission (FCC) places power limits upon devices that transmit as intentional radiators.
