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 three
screws that hold it. Set the cover aside
and discard the screws.
Step 2 - Remove the register by
removing the two screws that hold it. Set
the register aside and discard the screws.
Step 3– 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.
Step 4 – Next, turn the MTU over and
mount the register onto the MTU (see
illustration below) fastening the register to
the MTU with the #10 x 3/8” screws
provided.
Start the two screws into the mounting
holes, and then slide the register beneath
the screws, making sure that the wiggler
on the register is aligned with the MTU
coupler.
Tighten both screws to a torque not to
exceed 3-5 inch-pounds.
CAUTION!
Do not over tighten screws.
Excessive torque may
damage the MTU enclosure.
Use of power tools is not
recommended.
