Operation
Risk of electric shock. Can shock,
burn or kill. Do not touch sump pump, pump
motor, water, or discharge piping when pump is
connected to electrical power. Always disconnect
pump cord (power) before handling.
1. Plug this unit into a 115V outlet, on an indi-
vidual branch circuit, with a Class A, 15 amp
GFCI (Ground Fault Circuit Interrupter). Consult
your local electrician for information and avail-
ability.
2. Fill sump pit with water, pump will start auto-
matically when lower rod stop actuates switch
lever arm. When upper rod stop actuates
switch lever arm, pump will stop.
NOTICE Do not allow pump to run dry.
Risk of electric shock. Can shock,
burn or kill. Before attempting to service,
always disconnect power from unit.
3. The motor is equipped with an automatic reset
thermal protector to protect unit from overheat-
ing. When motor has cooled sufficiently, switch
will reset automatically and restart motor.
Repeated tripping could be caused by low volt-
age, long extension cords, clogged impeller,
very low head or lift, etc. Cycling of protector
will cause eventual motor burnout.
