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 screws
that hold it. Discard the screws and the
cover.
Step 2 - Remove the register by
removing the two screws that hold it. Set
the register aside and discard the screws.
Step 3 – Mount the adaptor to the meter
head using the two #10-24 x .75”
provided. Tighten these screws to a
torque not to exceed 15 -18 inch-pounds.
Step 4– Remove the paper backing from
the gasket provided to expose the
pressure sensitive adhesive. Place the
gasket on the back of the MTU with the
adhesive surface facing the MTU so that
it aligns over the three mounting screws
and the raised gasket surface of the
MTU.
