Installation
Note:
Please read all steps of installation instructions before beginning.
Note:
If using a repressurization pump, a third float should be used to turn the pump off when the tank is
empty.
1. Remove the bulkhead nut from the bulkhead fitting and place the bulkhead through the opening in the tank from the
outside, making sure the bulkhead gasket is on the outside of the tank. Loosely connect the bulkhead nut. Do not
tighten at this time.
2. Position the float tree assembly on the inside of the tank and pull the float wires through the bulkhead fitting.
Connect the float assembly tee to the bulkhead fitting by turning the bulkhead fitting from the outside of the tank.
Tighten the bulkhead nut.
Caution:
Do not tighten by turning the float assembly inside the tank, float damage can occur.
Tighten only by turning the bulkhead fitting from the outside of the tank.
3. Position the electrical conduit elbow on the outside of the tank, pulling with wires into the conduit elbow. Tighten
onto the bulkhead fitting.
4. Install SO cord (supplied by customer) through the strain relief fitting and attach it to the bottom of the conduit fitting.
Make sure enough wire is run into the conduit fitting.
5. Connect the wires from the SO cord to the float switch wires.
Note:
It is recommended to test the wiring by placing an OHM meter on the connections testing for
possible short or ground. All electrical connections shall be in accordance with the NESC guidelines and as
dictated by local authorities holding proper jurisdiction for local/state and or by U.B.C., and U.M.C.
guidelines for all mechanical means.
