motor is equipped with automatic resetting ther-
mal protector and may restart unexpectedly.
If protector trips, motor may be overloading. Check for the
following problems:
1. Not enough back pressure in discharge pipe.
2. Voltage too high or too low.
3. Wires to motor too small.
4. Motor incorrectly connected to power supply wires.
5. Defective motor.

Risk of electrical shock. Do not touch
sump pump, pump motor, water, or discharge pip-
ing when pump is connected to electrical power.
Always disconnect pump cord (power) before han-
dling.
1. Plug unit into 115 V. outlet. It is strongly recommended
that this unit be plugged into a Class A 15 Amp GFCI
(Ground Fault Circuit Interrupter). Consult your local
electrician for information and availability.
2. Fill sump pit with water, pump will start automatically
when lower rod stop actuates switch lever arm. When
upper rod stop actuates switch lever arm, pump will
stop.

3. The motor is equipped with an automatic reset thermal
protector to protect unit from overheating. When motor
has cooled sufficiently, switch will reset automatically
and restart motor. Repeated tripping could be caused by
low voltage, long extension cords, clogged impeller,
very low head or lift, etc. Cycling of protector will
cause eventual motor burnout.
