warnIng! disconnect pump from power<br />
source before maintenance.<br />
1.<br />
2.<br />
Clean the inlet screen on the intake port<br />
regularly to remove accumulated debris.<br />
Wipe the pump clean with a soft, damp<br />
cloth with soapy water. Do not use solvents.<br />
Do not get the electrical components<br />
wet.<br />
Drain water from pump before storage<br />
by disconnecting the water lines and<br />
turning the Pump upside down. If storing<br />
the pump for a long time, store it in a dry<br />
location, and apply a light layer of oil to<br />
the metal parts prior to storage, to inhibit<br />
rust. do not expose to freezing temperatures.<br />

troubleshooting<br />
After storage, check the Impeller to make<br />
sure it turns easily and is not oxidized.<br />
note: Turn off the switch and unplug the<br />
pump when performing maintenance.<br />
Problem Cause solution<br />
The pump won’t start 1. No power.<br />
1. Check connections, and breaker/fuse.<br />
The pump operates<br />
but it won’t discharge<br />
water<br />
Only a low volume of<br />
water flows<br />
2.<br />
3.<br />
Pressure switch disconnected.<br />
Thermal Protection cut out.<br />
4. Blocked impeller.<br />
1. Pump not primed.<br />
2.<br />
3.<br />
4.<br />
Lift height exceeded.<br />
Inlet tube not submerged.<br />
Air in suction pipe.<br />
5. Inlet screen clogged.<br />
1. Inlet pipe is too small.<br />
2.<br />
3.<br />
4.<br />
5.<br />
Liquid is too dirty.<br />
Lifting height exceeded.<br />
Tank’s rubber bladder under-inflated.<br />
Piping corroded, causing friction.<br />
Motor overheats often 1. Extension cord too long or wire size too<br />
small.<br />
Pump/motor cycles<br />
rapidly<br />
Tank bladder will not<br />
hold pressure<br />
Water pumps<br />
intermittently<br />
2.<br />
Pump cycling too often.<br />
Cut-in and cut-out pressure may be set too<br />
closely.<br />
1. Air inlet valve is leaking.<br />
2.<br />
3.<br />
Check gauge.<br />
Allow pump to cool.<br />
4. Free the impeller.<br />
1. Prime pump.<br />
2.<br />
3.<br />
4.<br />
Reduce lift height.<br />
Submerge the inlet.<br />
Check pipe and seals.<br />
5. Clean screen.<br />
1. Increase pipe diameter.<br />
2.<br />
3.<br />
4.<br />
Clean screen frequently.<br />
Reduce lifting height.<br />
Inflate to 26-29 PSI.<br />
2. Bladder is broken.<br />
2. Replace bladder.<br />
Water level is being drawn below foot valve. Lower foot valve.<br />
5. Replace piping, with plastic where<br />
possible.<br />
1. Eliminate use of extension cord or use<br />
shorter/heavier gauge cord.<br />
2. Cut-in and cut-out pressure may be set<br />
too closely; Have the pressure switch<br />
adjusted by a qualified technician.<br />
Have the pressure switch adjusted by a<br />
qualified technician.<br />
1. Check air tank for leaks using soapy<br />
water and replace bladder if needed.<br />
Follow all safety precautions whenever diagnosing or servicing the pump.<br />
disconnect power supply before service.<br />
do not disassemble the pump or motor as this will damage the water seals.<br />
All repairs should be performed by a qualified technician.<br />
