into wall outlet. If pump works,
proceed to check switch, if not, fault
is in pump or power supply.

TROUBLESHOOTING INFORMATION

PROBABLE CAUSES
Pump not plugged in.
Circuit breaker shutoff or fuse removed.
Accumulation of trash on mercury float switch. Clean float.
Remote float switch obstruction.
Defective switch.
Defective motor.
Remote float switch obstruction.
Pump is air locked.
Liquid inflow matches pump capacity.
Defective switch.
Loose connection in level control wiring.
Check valve installed backwards.
Check valve stuck or plugged.
Lift too high for pump.
Inlet to impeller plugged.
Pump is air locked.
Lift too high for pump.
Low voltage, speed too slow.
Impeller or discharge pipe is clogged.
Impeller wear due to abrasives.
No check valve in long discharge pipe allowing
liquid to drain back into basin.
Check valve leaking.
Basin too small for inflow.
CORRECTIVE ACTION
Plug in pump.
Turn on circuit breaker or replace fuse.
Check float path and provide clearance.
Disconnect switch, check w/ohmmeter. Open-infinitive resistance,
closed-zero.
Have pump serviced.
Check float path and provide clearance.
Shut power off for approximately 1 minute, then restart. Repeat
several times to clear air from pump. If system includes a
check valve, a 3/16" hole should be drilled in discharge pipe
approximately 2" above discharge connections.
Larger pump required.
Disconnect switch, check w/ohmmeter, Open-infinitive resistance,
closed-zero.
Check control wiring.
Check flow indicating arrow on check w/ohmmeter, Open-infinitive
resistance, closed-zero.
Remove check valve and inspect for proper operation.
Check rating table.
Pull pump and clean.
(See corrective action above.)
Check rated pump performance.
Check for proper supply voltage to make certain it corresponds to
nameplate voltage.
Pull pump and clean. Check pipe for scale or corrosion.
Replace worn impeller.
Install a check valve in discharge line.
Inspect check valve for correct operation.
Install larger basin.
