RF Exposure Notice (509)
The antenna of this transmitter must not be co-located or operating in conjunction with any other antenna
or transmitter.
The device should be installed so that people will not come within 20 cm (8 in.) of the antenna.
This equipment has been tested and found to comply with Part 15 of the FCC Rules. This equipment
generates, uses and can radiate radio frequency energy, and if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.

Remove Existing Cover & Prep Meter
Remove the existing index cover
and index from the meter.
Clean the meter index area
and make sure to remove
any remaining parts
of the old gasket.

Attach the Tamper Magnet Holder
On an American meter,
attach the magnet so that
the protrusion holding the
magnet points down and to
the left and the gap in the
circle fits around the
notch on the meter.
On a Rockwell meter, attach the
magnet holder so that the
protrusion holding the magnet
points down and to the left and
the inner pin is inserted into
the index screw hole. American

Inspect IMU
Inspect the IMU, ensuring that
there is no visible damage.
Check the front and rear gaskets.
Make minor placement
corrections as needed.
The front gasket should adhere
to the enclosure and keep the
screw holes clear.
The rear gasket should be
attached to the enclosure on the
left and right, and remain
straight in the middle such that
the gasket will seal between the
enclosure and meter. The
gasket must keep the screw
holes clear.

Connect Battery Cable Connector
Gently plug in the battery cable
connector to the PCB, if it is not
already connected.
The connectors are keyed. The
top side of the male connector
has a feature that fits into a slot
on the top side of the female
connector on the PCB.
Orient the connectors before
attempting to connect.
Carefully insert the male
connector while holding the
opposite end of the female
connector. Do not push the
male connector without holding
the opposite end of the female
connector.

Attach the Meter Index to the IMU
Align the IMU drive train
with the index wriggler.

Attach Meter Index to IMU
Use the two index screws
to firmly attach the index
to the IMU.
Index screw torque:
Rockwell: 6-7 inch pounds
American: 8-10 inch pounds
Rotate the drive shaft two turns from
the rear, clockwise or counter-
clockwise, and observe that the 2 foot
test hand also moves 2 turns. The test
hand should spin freely. If not, correct
by fixing or replacing the index or IMU.
Two rotations of the IMU drive shaft will
rotate the 2 ft drive hand two
rotations.

Attach IMU Assembly to Meter
Temporarily fasten the guide pins
to the meter (3-4 threads into
the meter). You will remove
these in a later step.
Using the guide pins, align the
IMU to the meter and match the
meter wriggler to the IMU drive
by adjusting the index test hand.
On the Rockwell meter, rotate
the magnet to 12 o’clock to
avoid the screw in the index
well.
Watch (from the side or top) the
IMU drive link to the meter
wriggler.
On the American meter, the
pin goes into the slot.
On the Rockwell meter, the
cup fits over the wriggler
(meter gear).

Attach IMU Assembly to Meter
Hold the enclosure against the meter to
maintain proper alignment to perform
the following checks:
If no gas is flowing through the meter,
verify that the half cubic ft test hand
rotates approximately 180 degrees when
turned gently by hand
If gas is flowing through the meter, you
should see the test hands rotating. You
do not need to manually rotate the test
hand.
Verify that:
There are no clicking or snapping
sounds
There is no gap between the meter and
IMU
The rear gasket seals the meter to the
IMU

Attach IMU Assembly to Meter
If you hear clicking or snapping, or if
there is a gap or a poor gasket seal,
remove the IMU and reinstall.
Repeat the verification checks.
Attach the index cover and 2
screws to the meter and IMU as
shown. On a Rockwell meter, the
curved side of the index cover goes
on top. The red tamper plugs will fit
to the upper left and lower right
corners.
Tighten the 2 screws.
Torque:
Rockwell: 6-8 inch pounds
American: 10-11 inch pounds

Inspect Gaskets
Verify that the front and rear
gaskets seal the mating surfaces
all the way around the IMU and
index cover.
If the gaskets have not seated
correctly, remove all the cover
screws, adjust the gasket
position, and reinstall the IMU.

Inspect the gaskets and install the tamper seals
Re-inspect the front and rear
gaskets to ensure that they
form a seal between the
index cover, enclosure, and
meter.
Use a nut driver to push the
three tamper seals into the
openings on the IMU (2 in the
index cover and 1 in the
battery door).
21

Prepare the IMU for Programming
Slowly pass the service magnet once (for 2 to 5 seconds) over the top of the IMU.
Doing so wakes up the IMU, enabling you to program it.
