Bracket mounting

The bracket kit contains a stainless steel angle bracket and PVC threaded disc
(Figure 6), which may be used to mount the transmitter on a support over the
liquid surface.

Installation instructions

1. Attach bracket to the disc using the three screws provided.
2. Attach the assembled bracket and disc to a rigid support over the liquid
surface.
The bracket may be bolted to a suitable cross member. Ensure the
transmitter is perpendicular to the surface to maximize the return echo size.
3. Use PTFE tape on the transmitter's screw thread.
4. Insert the transmitter into the disc.
5. Tighten to a torque of 1.5 ft-lb (2 N-m) using the transmitter's hexagon.
Do not use the transmitter housing to tighten.
