Grasp the clamped band shroud assembly by opposing edges and spread the opening
of the circular shape and place over the body OD at a machined shroud channel.
a. Position the shroud end with the guide pin holes and worm screw clamp nuts on
the same side of the meter which has the guide pins.
b. Align the guide pin holes in the shroud with the guide pins in the body and hold
this band shroud end against the body OD.
c. Position the opposite end of the band shroud near to the guide pin hole end and
engage the worm screw clamp thread ends into the worm screw clamp nuts.
With a flat blade screwdriver or 5/16 inch (8mm) hex driver rotate the worm
screw clamp nuts, each a little at a time, until the band shroud becomes snug
against the body OD.
Check the shroud for proper fit on the meter body and continue tightening the worm
screws.
a. Check to confirm that the band shroud assembly fully covers the meter body.
b. Check to confirm that the hem bends of the two shroud parts, located at the
bottom of the meter, are fully engaged.
c. If the shroud is misaligned, use a flat blade screw driver and loosen all worm
screw clamp assemblies by alternating between the worm screw clamp screws,
turning each a few turns at a time. Reposition the misaligned band.
Place one half of the top shroud over the worm screw clamps and the top shroud
support.
d. Insert the three hex head bolts and split lock washers into the top shroud and
align with the three holes in the top shroud support.
