Installation Considerations
1. Signal distance varies depending on the location of the D4100 MOSAIC. Those 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 roughly 1 3/4 inches make it possible to mount the D4100
MOSAIC through the lid. This can increase transmission range significantly.
4. Complete field installation of a D4100 MOSAIC 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” pictured
at right). Ensure that enough space exists
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.
