Mounting the Float Switch
Install the float switch in the following way:
Note: Floats are labeled HIGH and HIGH HIGH.
Therefore, always mount the HIGH float at the lowest
monitoring elevation.
1. Install a ¼-inch x 2 ¼-inch anchor bolt in the manhole wall just
below the rim. Select a location away from the monitor
mounting location and on the opposite side of the manhole
from the rungs. This will reduce the possibility of the float
switch and its cabling striking or getting tangled in the rungs or
monitor.
2. Establish the proper elevation (representing the trip point) at
which to hang the float switch, and then determine the distance
from that elevation to the anchor bolt.
3. Measure that same distance from the top of the float switch (top
of the float’s collar where the enclosure meets the cable) up the
cable.
4. Secure the cable to the anchor bolt using an anchor cable tie at
that location on the cable.
5. Slowly lower the float switch into the manhole until it is fully
suspended from the mounting location.
