Sensor Installation

6.
Press the sensor well cap into the top of the well with the excess sensor length hanging inside the well
housing.
7.
Press down the locking handle on the sensor well cap to secure it in position and to form a water-tight seal
between the sensor well cap and the monitoring well housing.
8.
Pass the end of the sensor cable through the nut, bushing, and cord grip fitting and into the Junction box (J-
box). Pull the excess cable through the fitting and out the opened side of the J-box.
9.
After sliding the J-box cord grip fitting up to the J-box, apply the UL-classified sealant (suitable for use with the
fuel involved) to the fitting then screw it into the J-box. Tighten the J-box cord grip fitting nut to ensure a
watertight seal at the sensor cable entry.
10. Using the wiring nuts, connect the wires from the sensor cable to the field wires from the console (see
General Product Wiring Diagram on page 2). Be sure to observe proper polarity between sensor and console.
11. Seal wire nuts with epoxy sealant following instructions in Figure 3.
12. For additional security, a padlock may be installed on the sensor cap to ensure that the locking handle cannot
be opened by unauthorized personnel.
