for Sprague/Actaris 'Curb-type' Gas Meters
Refer to Publication 471-2000, General
Installation and Wiring Guidelines for
general information covering the wiring
and mounting of STAR MTUs.
Step 1 – If necessary, remove tamper
seals from any of the four screws that
secure the index cover to the meter body.
Step 2- Loosen and remove the four
screws securing the index cover to the
meter. You may discard these screws as
they will not be re-used. Remove the
index cover and the index cover gasket
from the top of the meter and discard.
You will replace both the cover and the
gasket during reassembly.
Step 3 – Remove the two screws
securing the index to the top of the meter.
You may discard these screws as they
will not be re-used. Remove the index
register and set it aside.
Step 4 – Verify that the couplers and
shaft are attached to the pulser body as
shown below. Ensure that these
components are securely snapped
together and that the magnet is in place
on the Single-pin Index Drive.
Step 5 – Mount the index to the pulser
using the #6-19 Phillips screws provided.
You can start the screws in the posts on
the pulser body first. Then engage the
tabs on the index with the mounting
screws. Ensure that the pin on the index
drive engages the wiggler on the index.
