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
three (3) index cover screws.
2. Remove and properly dispose the three (3) screws holding the index
cover onto meter, with flat screwdriver. If any 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 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.
With a putty knife, scrap away any gasket material that remained on the
meter when the index cover was removed.

Mount Transmitter on meter
Verify that the transmitter is functional: check that the magnet on the front cam is
visible; with the HHT check the transmitter ID and validate with the transmitter
label.
Insure the three (3) mounting screws are available and within reach.
Place the AMR Transmitter onto the gas meter. Adjust the Transmitter shaft’s
position by holding it on the front side, and combine the Transmitter shaft
gearwheel with the gas meter shaft gearwheel.
1.
While holding the Transmitter in place, check that the shafts are correctly
positioned 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 three (3) mounting screws
with a Phillips screwdriver. Place all screws, then torque down the top
screw. Check shaft motion transfer again, then tighten the last two (2)
screws.
3.
Should any 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.

Assemble index and new cover onto
transmitter
1.
Install the two (2) index screws to their place in the Transmitter with the
Phillips screwdriver. Do not insert the screws fully, to leave space for the
index to slide in.
2.
Align the index shaft with the Transmitter’s shaft; adjust the wriggler’s
position by holding the proving hand on the index front side, and insert
so that there is no interference.
3.
Tighten the index screws, securing the index to the Transmitter.

4.
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.
5.
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.
