3. Make sure float move freely up and down
4. If voltage is under 108 volts, check wiring size
5. Install pump on dedicated circuit.

2. Clean out impeller
3. Reverse position of check valve
4. Drill 1/8 inch hole in discharge line between
pump and check valve
1. Wipe off surface of sensor (see Figure 5)
2. Additional run time will not damage pump
