Note: The motor in this unit contains thermal protection that responds to motor current and heat from the motor winding and ambient
temperature. When the combination of current and heat exceeds a pre-determined point, the protector opens and interrupts the circuit.
When the winding termperature returns to a more normal level, the protector will automatically reset.

properly wire outlet
Check water supply and valving
Refer to owner's manual section on
proper priming technique
Check water supply and valving
Install a pressure reducing valve on inlet
to reduce inlet pressure
Set the pressure in pressure tank to
2 psi lower than cut-in pressure
Place check valve after pressure tank
Press the power button on the user
interface
Check the supply voltage and correct
if possible
Check the supply voltage and correct
if possible
Supply cold water to the pump
Reset pump by pressing power button
