5. With the Mounting Bar in the proper orientation regarding the invert, turn the knob to extend the rod to
just short of the manhole frame walls. The Mounting Bar should be installed a minimum of 14 inches
(355.6 mm) below the rim of the manhole, which minimizes the risk that the bar would be struck when
opening the manhole lid. When possible, install the bar on the manhole frame so that it is installed on
a solid, vertical surface. While less ideal, it is acceptable to place the bar below the frame, as long as
the bar is mounted securely.
6. Reference the bubble level while tightening the knob on the Mounting Bar in the manhole frame to
ensure that the bar will provide a level sensor mounting surface. Tighten the knob by hand to extend
the bar and provide as tight of a fit as possible within the frame. Grip the bar firmly and pull forcefully
to confirm that the bar will not move, slip, shift, or drop.

Installing the Stainless Steel Wall Mount Bar
The Stainless Steel Wall Mount Bar is designed as an alternative method of securely positioning the ECHO
in the manhole over the flow.
Perform the following procedure to install the Mounting Bar:
1. Position the bracket on the manhole wall, such that the ECHO will overlook the flow. Refer to “Installing
the Mounting Bar”, Step 4, for additional configurations to accommodate alternative flow paths.
