Sensus Meter Installation
3. Remove one index mounting screw completely. Hold one hand under the index to catch the screw. While
removing the other mounting screw, pull the index away from the meter to keep the index backplate
against the back of the screw. Remove the screw completely after the index is free of the meter.
4. Set the index aside where it will not be damaged or fill with dirt, rain, or snow. You will mount the index
in the ERT later in this procedure.
5. Verify the index mounting screws are 5/8-inch long and not corroded. If the screws are the correct length
and not corroded, retain for later use. If you discard the original screws, use the correct replacement
screws (see Installation Prerequisites on page 14.)
6. Remove the old gasket, gasket residue, and dirt from the meter (if applicable). The meter face must be free
of gasket residue or dirt before you install the 100G.
Assembling the Gas ERT Module and Index

To assemble the ERT module and index
1. Separate the ERT module housing from the clear cover by pulling the cover straight out from the housing.
Set the ERT module cover aside where it will not be damaged or fill with rain, dirt, or snow. You will
replace the cover later in this installation procedure.
