MAINTENANCE (CON'T)
6. Check the priming hole for obstruction. (Figure 1).
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. Use a pin or paperclip to clean the priming hole and
air escape channel.
f. Reinstall impeller plate, base, screws and strainer.
7. 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.

8. 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.
9. 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
Do NOT use pump if any part of the switch
housing or probe is cracked, broken or missing.
PUMPING HEIGHT
When water is pumped to an elevated position, any volume
that has not reached the discharge outlet can flow back
through the pump when the pump shuts off. This back-flow
can cause the water level in small areas to rise enough to
re-start the pump. The check valve/hose adapter included is
required in this situation. For proper operation, make certain
the check valve is oriented as instructed on check valve body.
In small areas a check valve is required to prevent
backflow. Without a check valve the pump may cycle
continuously and potentially wear out the pump components.
