The testhand should spin freely. If not, correctby fixing or replacing the index or IMU.Two rotations of the IMU drive shaft willrotate the 2 ft drive hand tworotations.
15© 2010 Silver Spring Networks | Company Confidential Attach IMU Assembly to Meter•Temporarily fasten the guide pinsto the meter (3-4 threads intothe meter). You will removethese in a later step.•Using the guide pins, align theIMU to the meter and match themeter wriggler to the IMU driveby adjusting the index test hand.–On the Rockwell meter, rotatethe magnet to 12 o’clock toavoid the screw in the indexwell.–Watch (from the side or top) theIMU drive link to the meterwriggler.•On the American meter, thepin goes into the slot.•On the Rockwell meter, thecup fits over the wriggler(meter gear).
16© 2010 Silver Spring Networks | Company Confidential Attach IMU Assembly to Meter•Hold the enclosure against the meter tomaintain proper alignment to performthe following checks:–If no gas is flowing through the meter,verify that the half cubic ft test handrotates approximately 180 degrees whenturned gently by hand–If gas is flowing through the meter, youshould see the test hands rotating. Youdo not need to manually rotate the testhand.•Verify that:–There are no clicking or snappingsounds–There is no gap between the meter andIMU–The rear gasket seals the meter to theIMUHalf foot test hand Two foot test hand
17© 2010 Silver Spring Networks | Company Confidential Attach IMU Assembly to Meter•If you hear clicking or snapping, or ifthere is a gap or a poor gasket seal,remove the IMU and reinstall.Repeat the verification checks.•Attach the index cover and 2screws to the meter and IMU asshown. On a Rockwell meter, thecurved side of the index cover goeson top. The red tamper plugs will fitto the upper left and lower rightcorners.•Tighten the 2 screws.Torque:–Rockwell: 6-8 inch pounds–American: 10-11 inch pounds
18© 2010 Silver Spring Networks | Company Confidential Inspect Gaskets•Verify that the front and reargaskets seal the mating surfacesall the way around the IMU andindex cover.•If the gaskets have not seatedcorrectly, remove all the coverscrews, adjust the gasketposition, and reinstall the IMU.
