The electronics housing can be rotated up to 180 degrees in either direction to
improve field access, to improve operational functions, or to better view the
optional LCD meter. To rotate the housing, perform the following procedure:
1. Loosen the housing rotation set screw using a 3/32-in. hex wrench.
2. Rotate the housing clockwise to the desired location. If the desired
location cannot be achieved due to thread limit, rotate the housing
counter clockwise to the desired location (up to 360° from the thread
limit).
3. Retighten the housing rotation set screw to 20 inch pounds.
