Elster American Meter Installation
3. Unscrew one index mounting screw completely. Hold one hand under the index to catch the screw. While
you remove 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.
Set the index aside where it will not be damaged or fill with dirt, rain or snow. You will mount the index
to the ERT module later in this procedure.
4. Verify the index mounting screws are 3/16-inch long and not corroded. If the screws are the correct length
and not corroded, retain for later use. If you discarded the original screws, use the correct replacement
screws (see Installation Prerequisites on page 14).
5. Remove the old gasket, gasket residue and dirt from the meter (if applicable). The meter face must be free
of gasket residue and foreign materials before you install the 100G series gas ERT module.
