Hazardous
HANDLING.

This guide is designed to help identify reasons for potential
operating problems. It is not a service guide.
DISMANTLING OF PUMP VOIDS WARRANTY.
Servicing of pump other than simple cleaning of pump inlet
or impeller should be referred to the factory or its autho-
rized service centers.
NOTE:
The manufacturer assumes no responsibility for
damage or injury due to disassembly.
PUMP DOES NOT RUN OR HUM:
1) Line circuit breaker may be off, tripped or loose. Have
a certified electrician check fuse or breaker.
2) Water level in pit may be too low to activate switch.
Add more water to pit.
3) Plug on power cord may not be making contact in
receptacle. Check security and connection.
4) Float may be obstructed. Make sure float is free and not
interfering with the pit wall or other obstruction.
5) If all symptoms check OK, the motor winding may be
open. Consult factory.
PUMP RUNS OR HUMS BUT DOES NOT DELIVER
WATER:
1) Check valve may be installed backwards or is defective.
Check to make sure it is installed properly and flapper
in valve is free to move.
2) Discharge line may be blocked or frozen. Check to see
if line passes through cold areas or is blocked.
3) Pump may be air-locked. Make sure air bleed hole was
drilled in discharge pipe. See Figure A for proper
location of bleed hole.
4) Vertical lift is beyond pump's capability. Pump's
maximum lift capability is 17'.
NOTE:
At the pump's maximum lift there will be
no flow.
5) Inlet screen of pump is plugged or the impeller is
jammed. Remove the pump screen and clean inlet and
impeller.
PUMP RUNS AND REMOVES WATER BUT DOES
NOT SHUT OFF:
1) Float is stuck in the "ON" position. Check to make
sure the float is free to move up and down without
obstruction.
2) Switch is defective. Consult factory.
PUMP RUNS BUT DELIVERS VERY LITTLE WATER.
1) Vertical lift is approaching the pump's maximum lift
capability. Refer to the above maximum lift chart.
2) Pump's inlet is partially blocked. Check to make sure
the inlet is clear of debris.
3) Discharge line is partially blocked. Check for blockage.
4) Check valve is not opening all the way. Check for
defective or blocked check valve.
CIRCUIT BREAKER TRIPS OR FUSE BLOWS WHEN
PUMP STARTS
1) Fuse or breaker size is too small. A 15 amp breaker
should be used.
2) Other major appliances are on the same circuit. Pump
should be on its own circuit.
3) Pump is connected to an extension cord or wiring is
inadequate. Have an electrician check for proper
wiring.
4) Defective motor or switch. Consult factory.

Maintenance

• Pedestal sump pump have open, exposed motors. Take
precautions to make sure the motor does not get wet
from dripping pipes, etc.
• Pour an ounce of 20 or 30 weight oil into the hole near
the top of the pedestal column every 6 months. A label
next to the hole designates where to add the oil. See
Figure B.
• Pour enough water into the sump pit to activate the
pump periodically when not normally in use.
• Check periodically to make sure the pit is free from
accumulated debris, rocks or other objects that may
potentially jam the pump.
