Remove index 1. Remove and properly dispose the two (2) screws holding the index onto the meter, with small flat or Phillips screwdriver. 2. Remove the index and carefully clean any debris from it. Inspect for proper index operation by turning the input shaft and verifying that the gearing turns freely. Also, inspect the index for any missing or broken hands. Place the index, or a new index if necessary, on a clean surface near you for reinstallation later. 3.

Mount Transmitter on meter Insure the four (4) mounting screws are available and within reach. Place the AMR Transmitter onto the gas meter, aligning the Transmitter’s shaft with the gas meter’s male or female wriggler; adjust the Transmitter shaft’s position by holding it on the front side, and insert pin into hole. 1. While holding the Transmitter in place, check that the shafts are aligned by gently rotating the Transmitter’s shaft with your other hand. There should be just a slight freedom of motion.

Assemble index and new cover onto transmitter 1. Insure the two (2) index screws are available and within reach. 2. Install the right side index screw to its place in the index (use tweezers if more convenient). Skip this step if assembling a plastic index. 3. Insert #1 Phillips screwdriver to hold screw in place, while placing the index onto the Transmitter, then insert the screw just 2-3 turns, so that the index fits loosely on the Transmitter.

5. Install (use tweezers) the left side index screw to its place in the index. Use left hand to install the screw and secure index into place. With plastic index: 6. While the index is still a bit loose, centralize its position. Check that the motion is smoothly transferred and there is no binding between the shaft and wriggler, by gently rotating back and forth the index’s proving hand. 7. Tighten the index screws, securing the index to the Transmitter.

8. Install the index cover supplied (it only fits in one direction – the bump fits in the right side of the Transmitter). Check that the gasket is properly aligned and fasten to the Transmitter with the four (4) index cover screws. CAUTION ! Use care when working with a power screwdriver to insert screws in the plastic Transmitter box. Over tightening will damage the box and/or weaken the contact. 9. Install the two snap seals in the index cover and insert fully with the aid of a ¼” nut driver.
