Monitor Installation 7-9
Positioning the nuts on the stud to receive the mounting bracket
11. Mount the bottom of the mounting bracket onto the monitor
flange with two 3/8-inch x 1-inch hex bolts, 3/8 – 16 nex nuts,
and 3/8-inch washers. It may be necessary to drill new holes in
the flange.
12. Carefully lower the monitor into the manhole, and place the
keyhole in the bracket over the outer nut on the stud.
Note: ADS strongly recommends attaching a security line
to the monitor before lowering it into the manhole to avoid
accidentally dropping the monitor down into the manhole
during installation.
13. Slide the bracket against the inner nut and washer, and tighten
and secure the outer nut against the bracket.
14. Neatly coil and secure the excess sensor and communication
cables in the manhole to simplify future monitor service
activities. Secure the cables to plastic anchors or ¼-inch x 2¼-
inch anchor bolts using 14-inch cable ties.
Note: Be careful to avoid damaging the sensor cables
during installation activities. Even small pinholes in the
cable can cause a sensor to malfunction or fail.
