AMR Transmitter Mounting Instructions for American Meter AC250, AL175, AL250, AL5B, AL225, AL425 4 AMR Transmitter Installation Installation Tasks 1. Remove index cover. 2. Remove index from gas meter. 3. Mount AMR transmitter onto gas meter. 4. Assemble index and cover onto AMR transmitter. 5. Initialize AMR transmitter with HHT. Remove index cover 1. Use small flat screwdriver to punch out the seals that cover two (2) of the four (4) index cover screws. 2. Remove and properly dispose the four (4) screws holding the index cover onto meter, with flat screwdriver. If two (2) or more screws shear off during the cover removal (or were previously sheared off), the meter will need to be replaced by a qualified utility representative. Reinstall any index cover screws that were removed and cap with seals if possible. Enter the appropriate information in the Mint HHT and skip to the next work order. 3. Remove the index cover and dispose of properly.

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. With a putty knife, scrap away any gasket material that remained on the meter when the index cover was removed.
AMR Transmitter Mounting Instructions for American Meter AC250, AL175, AL250, AL5B, AL225, AL425 6 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. 2. Attach the Transmitter to the meter using the four (4) mounting screws with #3 Phillips screwdriver. Place all screws, then torque down two (2) diagonal screws. Check shaft alignment again, then tighten the last two (2) screws. 3. Should two (2) or more screws shear or strip during the installation, the meter will need to be replaced by a qualified utility representative. Remove the transmitter and reinstall the index and index cover on the meter with the original screws. Enter the appropriate information in the Mint HHT and skip to the next work order.

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. In case of a plastic index, or an index with open screw positions, first insert the right screw 2-3 turns and then slide the index mounting slot behind the screw head. 4. Align the index male or female wriggler with the Transmitter’s shaft; adjust the wriggler’s position by holding the proving hand on the index front side, and insert pin into hole.

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.

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. Align the end of the nut driver on the snap seal and tap the end of the nut driver handle with your hand until it is fully seated. !
