Monitor and Sensor Installation 3-35
Select a location that will allow you to remove the monitor
easily during service visits using the mounting bracket
(extension handle).
Select a location that provides only a minimal potential for
the monitor to experience surcharge conditions.
Select a location that will prevent the manhole lid from
potentially damaging the monitor during removal or when
rotating in the opening.
2. Hold the top end of the mounting bracket against the manhole
wall, and mark the location for the mounting hole through the
keyhole in the bracket.
3. Install an 3/8-inch (8 mm) anchor bolt in the hole.
Note: Make sure all anchor bolts, studs, nuts, and
washers used in mounting the monitor are stainless steel.
4. Twist a 3/8-inch (8 mm) nut onto the anchor bolt, but do not
tighten it down. Leave enough space between the nut and the
wall for the thickness of the mounting bracket.
5. Mount the bottom of the bracket onto the monitor flange with
two 3/8- x 2-inch (8- × 50-mm) bolts and nuts. It may be
necessary to drill new holes in the bracket.
