The standard probe (Figure 1-
2) consists of a 1” (2.5 cm) diameter hydrocarbon float and a 1” (2.5 cm)
diameter water float. When the hydrocarbon float rises, it activates a time delay which turns on the system
(after a user-set period of time). This time may be varied by adjusting the potentiometer within the EP box. A
preset delay can prevent the pump from turning on and off too frequently. The water float prevents the pump
from running when the intake is in water.
