Grounding
Always ground the housing in accordance with national and local electrical codes.
The most effective grounding method for the housing is a direct connection to earth
ground with minimal impedance. Housings have an external earth ground point for making
this connection.
Adjust display rotation
To rotate the housing ( Figure 3-4 ), perform the following procedure:
1. Loosen the set screw until the level detector housing can rotate smoothly.
a. Do not unscrew all the way. Rotating the housing, without this screw in place, can
damage the internal wiring.
2. First, rotate the housing clockwise to the desired location.
a. If the desired location cannot be achieved due to the internal thread limit, rotate
the housing counterclockwise
3. Re-tighten the set screw.
