TROUBLESHOOTING
1. Pump does not run or start when water is up in
tank.
a. Check for blown fuse or tripped circuit breaker.
b. Check for defective level switch.
c. Where control panel is used be sure H-O-A switch
is in the AUTO position. If it does not run, turn
switch to the HAND position and if the pump
runs then the trouble is in the automatic electrical
system. Have an electrician make electrical checks.
d. Check for burned-out motor. Occasionally lightning
can damage a motor even with lightning protection.
e. Where plug-in cords are used be sure contact
blades are clean and making good contact. DO
NOT USE PLUG-IN CORDS INSIDE A BASIN OR
WET WELL.
2. Pump runs but does not deliver ow.
a. Check for airlock. Start and stop pump several
times. If this does not help it may be necessary
to loosen a union in the discharge line to relieve
airlock.
b. Check valve may be installed backward. Check ow
arrow on valve body. Check shut-off valve. It may
be closed.
c. Check vertical elevation of discharge pipe. It may
be higher than pump can support.
d. Pump inlet may be plugged. Remove pump to
check.
e. Level control ball or weight may be stuck on side of
basin. Be sure it oats freely.
RISK OF ELECTRICAL SHOCK. Always
unplug power cords or turn off all main and branch
circuit breakers before doing any work on the pump.
If control panel is remote from pump, disconnect lead
wires to motor so that no one can turn the circuit breaker
back on.
