Installation Instructions

MTU Instruction
for American Meter Company Gas Meters
Tools Required
To mount the MTU to these meters, you
will need the following tools and
equipment:
• Safety glasses
• Phillips screwdriver
• Slotted screwdriver
Installation Procedure
Before installing the MTU, all anti-tamper,
safety, and security hardware must be
removed from the clear register cover.
Step 1 - Remove the existing clear
register cover by removing the four
screws that hold it. Discard both the
screws and the cover.
Step 2 - Remove the register by
removing the two screws that hold it. Set
the register aside. Discard the screws.
Step 3 - Mount the register onto the MTU,
fastening the register to the mounting
holes shown here with the #8 x 3/8”
screws provided.
Start one of the two screws into the
mounting hole, and then slide the register
beneath the screw aligning the wiggler on
the register with the MTU coupler.
CAUTION!
Do not over tighten screws.
Excessive torque may
damage the MTU enclosure.
Use of Power tools is not
recommended.
Then insert the second screw and tighten
both screws to a torque not to exceed 3-5
inch-pounds.
Note: On some odometer-style registers
like the one shown below, slight
protrusions on the back of the register
assembly can interfere with proper
alignment of the register. Should this
occur, use a diagonal cutting plier to trim
the two wire guides on the MTU to the
right of the coupler. Trim these guides as
close to flush with the MTU enclosure as
possible. (See MTU photo below.)
