2. Decide whether the switch needs to function as normally open (NO) or normally closed (NC). This determines the position
of the switch float.
3. Read the two-character inscription above the center of the float (Figure 14). The inscription should be in the upright
position (it can be read) when the LevelMaster is in the vertical position. It will read either NO or NC (Figure 14 displays
NO). If it is not in the desired position:
a. Pull the retainer clip off.
b. Turn the float over.
c. Re-install the float switch.
d. Place the retainer clip back into place.
