Installation Instructions

MTU Instruction
for Hersey Water Meters
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. It is recommended that the
screws be tightened to no more
than 4 – 5 in-lbs. Overtightening
the screw can stress and possibly
fracture 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.
Note: When connecting a dual port MTU
to a compound meter, connect port 1
(black jacket) to the primary, or high-flow
register and port 2 (grey jacket) to the
secondary or low-flow register.
Step 3 – Make a final visual check of the
wiring from the MTU to the meter register.
Verify that the cable routing is neat,
secure and professional.
Step 4 – Once installation and wiring are
complete, program the MTU using the
STAR Programmer Software and your
MTU Programmer.
