OPERATION
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 individ-
ual branch circuit, with 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 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.
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.
