Installation Instructions

MTU Instruction
for Sprague/Actaris 675A, 800A and 1000A Gas Meters
Step 5 – Place the lower gasket onto the
meter, aligning it as shown to insure that
the openings for the index bolts and index
cover bolts match up with the threaded
holes on the top of the meter.
Step 6 – Break out the tab for either the
front or rear wire exit on the bottom edge
of the pulser body, depending on how you
plan to mount the MTU. (See the
illustration below.)
Step 7 – Assemble the couplers and
shaft to the pulser body as shown in the
illustration below. Ensure that the
magnet is mounted on the Standard
Coupler, and that the retaining shaft is
securely snapped into both couplers.
Step 8 – Place the pulser on the lower
gasket, aligning the bottom coupler on the
pulser with the wiggler on the meter.
Align the corner mounting holes on the
pulser with the mounting holes on the
index base plate.
Step 9 – Position the index on top of the
pulser, aligning the drive pin on the index
with the slot on the tall coupler. Ensure
that there is no binding.
Note: On some models, a ‘shorter’ index
may not allow sufficient clearance
between the tall coupler and the index. In
this case, replace the standard shaft with
the extended shaft and insert the nylon
spacers provided between the index and
the pulser body.
