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.
NOTICE Do not allow pump to run dry.
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.
Corrective Action(s)
Check fuse, circuit breaker, power cord and electircal outlet.
If voltage wiring under recommended minimum, check size of wiring
from main source. If OK, contact Electric Comapny or local Hydro
authority.
Operate switch manually and replace if inoperative.
Check to see float is not rubbing sump wall or float rod rubbing or
stuck against sump cover.
Replace float if filled with water.
IF pump has been running and stops before sump is emptied,
automatic overload may have tripped. Check inlet screen to be sure
impeller is not jammed. If so, free impeller of obstruction.
Check power cord, automatic switch and motor. Replace faulty parts
as needed.
Check inlet and clean if needed.
Clear discharge line and check valve for obstruction.
Refer Corrective Actionon low line voltage in above section.
Dril a 1/8" (3.2mm) hole in discharge pipe just above pump body but
below the check valvee.
Replace impeller or shaft as needed.
Lower float rod stop.
Replace automatic switch.
Refer to No. 5 in Insallation instructions.
