MTU Instruction
for Actaris/Sprague/Schlumberger Gas Meters
Step 5 – Next, assemble the couplers
and shaft to the MTU. Place the flat,
disc-shaped coupler on the shaft and
insert the shaft through the front (register)
side of the MTU.
Then snap the magnet holder on the shaft
from the back of the MTU. Ensure that
both couplers are firmly attached to the
shaft.
Step 6 – Now, 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.
Step 7 – Check that the register is
properly engaged by rotating the coupler
on the back of the MTU and observing
the register dials.
