1. Unpack unit and check for shipping damage. 2. The system consists of two components, the 404-4 controller and the 406 sensor. 3. The controller, which has 7 wires extending from the end of a 1/2" nipple, must be first connected to either the junction box of the dispenser or, the submersible pump as follows and as shown in Figures #1a and #Ib. A. Dispenser. (i) Shut off the power to the dispenser. This is extremely important not only to avoid possible electrocution, but also to prevent any sparks occurring in the presence of gaso- line vapors and thereby causing an explosion. (ii) Remove the cover from the junction box and locate a spare threaded hub. Remove the plug from the hub and if needed install a reducing bushing so that you have a 1/2" threaded opening. (iii) Feed the 7 wires through this opening and thread the 1/2" nipple into a hub. Tighten the nipple using a wrench on the nipple and not the body of the controller. (iv) Connect the wires as shown in Figure #2. (v) . The sensor should now be plugged into the 4 -wire female plug on the end of the controller. Cover the plugs with electrical tape. WARNING: Never plug or unplug the sensor unless the controller is de -energized. Doing so will damage the unit and void the warranty. (vi) Position the sensor in the bottom of the container at whatever level you want the dispenser to be shutdown. Remember that the unit will shut down when liquid rises to a point 3/8" above the bottom of the sensor. The excess cable should be looped and secured with a tie -wrap so that the sensor is suspended at the appropriate position. Many containment pans have a sump for locating the sensor. (vii) Turn the dispenser power back on afteryou have replaced the junction box cover. The dispenser should now operate normally. (viii) To test the cutoff, insert the sensor into a cup of water. The sensor is affected by ambient light, therefore test the sensor below grade and/or shielded from direct light. The dispenser should shut down when the sensor is placed into at least 3/8" of water. Remove the sensor from the water to restore power to the dispenser. NATE: If controller relay cycles or oscillates when sensor is tripped, it is likely that the controller is switching its own power. Check the appropriate wiring diagram to confirm that controller is wired properly. Make sure that the orange /black, red and black wires are tied tp power from the breaker and the orange wire feeds the dispenser.
