Supplies and Tools Required
See Publication 471-2000, General
Installation and Wiring Guidelines for a
complete list of recommended tools and
supplies for MTU Installation.
Installation Procedure
Step 1 - Select a mounting location for
the MTU that will allow optimum signal
transmission, and install any needed
wiring. Be sure to follow all General
Installation and Wiring Guidelines as
outlined in Publication 471-2000.
Step 2 – Select the wiring diagram that
applies to the meter you are connecting
and make the appropriate wiring
connections.
a. Direct Wiring to Meter - MTU
wiring is supplied stripped to a
standard length that fits water
meters with screw terminals.
Simply wrap the wires around the
screw terminal and tighten the
screw hand tight. Over tightening
the screw can stress and possibly
damage the wire.
b. Water Meter with Integral Cable -
If the water meter is supplied with
an integral cable and a cable-to-
cable splice is necessary, use a
gel-filled wire splice designed for
outdoor (moisture applications) to
seal the individual connections.
