Elster American Meter Installation
2. Carefully align the ERT module's four screw holes with the holes on the meter. Attach the assembly using
the original mounting screws if they are the correct size and are not corroded (1/4 - 20 x 5/8-inch screws.)
If you discarded the original screws, use the correct replacement screws (see Installation Prerequisites on
page 14). Tighten the screws in an alternating, diagonal pattern as shown in the photo:
• Insert first screw and tighten 1/4 to 1/2 turn after the screw contacts the meter connection.
• Insert the second screw and tighten 1/4 to 1/2 turn after contact with the meter connection.
• Insert the third screw and tighten 1/4 to 1/2 turn after contact with the meter connection.
• Insert the last screw and tighten 1/4 to 1/2 turn after contact with the meter connection.
3. Return to the first screw and tighten. Continue with the second, third and last screw until all screws are
tight. Use equal screw tension to tighten each screw.
Important Meter manufacturers: torque the mounting screws 15 to 20 inch-pounds.
4. Place new tamper seals over the two screws with tamper seal mounts. Press tamper seals into place using
an 11/32-inch nut driver or similar blunt tool.
5. Complete necessary paperwork and verify all excess materials are removed from the customer premises.
