Elster American Meter Installation
Caution If the index wriggler has a drive slot, place the ERT shaft drive post into the index drive slot.
Failure to mate the ERT module shaft with the index drive post (or slot) can cause binding and lead to
poor registration or meter failure.
8. Install and tighten the left index mounting screw (for indexes with either mounting screw slots or holes).
Tighten the right index mounting screw. Install and tighten index mounting screws evenly.
9. Slide the ERT module cover over the index and housing. Verify the cover is installed correctly. The ERT
label should be clearly visible and easily read.
