Elster American and Itron Commercial Meter Installation
Index covers may (or may not) have tamper seal cups (on the back of the cover) for added security. Index
removal assumes the installer removes any tamper seals or wires before continuing with these instructions.
Note It may not be necessary to dismantle your commercial index assembly (index and cover). These
instructions do not include index/cover assembly for those applications.
Some diaphragm commercial meters do not require an index assembly mounting plate. Indexes can be
mounted directly to the ERT module.
To remove the index assembly
1. Remove any tamper seals (1) (or wire seals) from the index cover and mounting plate screws (2). Set the
index and cover assembly aside. You will re-install it later in these instructions.
2. Remove the index cover screws from the meter. Verify screws are 1/2-inch long and are not corroded. If
the screws are the correct length and are not corroded, keep them to re-install the 100G assembly later in
this procedure. If the screws are damaged or not the correct length, discard.
Note Properly dispose all unused screws, old index covers, gaskets, tamper seals, and other leftover
materials. Do not leave materials on customer premises.
3. Remove the tamper seals from the mounting plate.
