using 1-inch NPT piping or use the mounting surface
with a bracket. Position the 2-inch NPT threaded
connection at the height where you want the level
switch to operate. The 2-inch NPT threaded

NOTE: A typical installation with blocking
and bleed valves is shown at right.

Install the LS200 or LS200N/NDVO/NDVOR in the 2-
inch NPT connection of the float chamber. BE SURE
float travel is not restricted and that the float is tight onto the float shaft.

To complete installation and wiring, follow the instructions for mounting directly into
wall of the vessel and for wiring.
