OPERATING INSTRUCTIONS AND PARTS MANUAL

MAINTENANCE

1. Periodic cleaning is required to maintain performance of the
pump. Follow the cleaning steps listed below:
a. Disconnect pump from power source.
b. Remove the strainer.
c. Remove the four (4) base screws (Figure 1).
d. Remove the base and impeller plate.
e. Remove the debris and make sure the impeller turns freely.
f. Reinstall impeller plate, base, screws, and strainer.
g. Use a pin or paperclip to clean the priming hole and air
escape channel.

WHEN REATTACHING THE BASE (INLET SCREEN), BE SURE THAT
THE "PLUGGED" SCREEN IS ORIENTED BELOW THE SWITCH.

TROUBLESHOOTING

1. Verify pumping height does NOT exceed 13 feet (See Figure
A). If pumping height is greater than 13 feet, this pumps automatic
feature will not operate correctly.
2. Verify water depth is 2-1/8 inches or greater.
3. To verify pump is operating correctly.
a. Disconnect pump from power source.
b. Connect hose adapter/check valve and discharge hose to
pump.
c. Immerse pump in a bucket or tub of water at least 2-1/8
inches
in depth.
d. Place the other end of the discharge hose outside the
bucket, so the water will pump out.
e. Plug power cord into a grounded 120 volt GFCI power
outlet. The pump should start after 2 seconds of detecting
water. Once the pump removes the water to a depth of 3/4
inch, the pump will stop automatically.
f. If pump does NOT operate, unplug power cord and proceed
to maintenance –refer to cleaning instructions.
4. To verify discharge hose is free from a blockage.
a. Connect hose to another water source such as a faucet.
If water flows through hose, return to step 3a. If water is
restricted, verify discharge hose is unwound. Remove all
kinks, bends, or obstructions in hose.
b. If pump is still NOT operating, refer to cleaning instructions
5. If pump runs continuously, unplug the unit. Once unplugged,
remove the strainer and check for debris stuck inside the sensor body
(Figure 2). Remove any trapped leaves, debris or dirt.
Figure 2 - Remove Debris From Sensor
6. If the pump cycles on and off too often the electronic switch
may need cleaning. Disconnect pump from power source, remove
the strainer and turn the pump upside down. The sensor probe
will be visible inside the switch housing. Clean inside the housing
gently scrubbing with a small brush using soapy water. Then rinse
thoroughly with clean water.
7. When temperatures drop below freezing remove pump from
service and store indoors to protect pump from damage due to ice.
The pump has a unique protection circuit to protect the motor from
a locked impeller condition possibly caused by debris buildup or
from a "frozen" impeller situation caused by ice formation. When
the pump is activated and a locked impeller condition is detected
the unit will automatically shutdown to protect the motor from
overheating. The pump will continue this on/off cycle for a period
of time to attempt to "free" the impeller until eventually the unit
will remain off for a period of 12 hours checking twice a day for a
"freed" impeller. Once the pump is able to operate correctly the
pump will resume normal operation. To reset this delay without
waiting 12 hours momentarily unplug the pump.
