MTU Instruction
for Sprague/Actaris 675A, 800A and 1000A Gas Meters
Fasten the index to the meter with two of
the ¼-20 x 2-1/4” slotted, stainless steel
fillister head bolts provided.
Step 10 – Place the index cover gasket in
position on top of the pulser and then
place the index cover on the top of the
gasket. Fasten the index cover to the
meter using the four remaining ¼-20 x 2-
1/4” slotted, stainless steel fillister head
bolts.
Installation of the pulser is now complete.
If you will be remotely mounting the MTU,
refer to Publication 471-2000, General
Installation and Wiring Guidelines for
general information covering the wiring
and mounting of STAR MTUs. Continue
to Step 11 if you will be mounting the
MTU to the pulser body.
NOTE: The pulser and MTU can be
supplied pre-wired or as separate
assemblies. If provided as separate
components, connect the three wires in
the pulser cable (red, black, and white) to
the corresponding wires in the MTU
cable.
Step 11 – Continue here to mount the
MTU to the pulser using the adaptor
provided. Begin by positioning the
adaptor on the back (or front) of the
pulser body and attach it using the two
#8-18 x ½” Phillips pan head thread
forming screws provided.
Step 12 – Bundle the excess wire into the
compartment on the adaptor.
