WHEN REATTACHING THE BASE (INLET SCREEN), BE SURE THAT THE
SIX (6) "PLUGGED" HOLES ARE ORIENTED BELOW THE SWITCH

7. If pump runs continuously, unplug the unit. Once unplugged,
check for debris stuck inside the sensor body (Figure 3).
Remove any trapped leaves, debris or dirt.
8. If the pump cycles on and off too often the electronic switch may
need cleaning. Unplug the pump and turn 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.
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. A check valve

[Check Valve Sold Separately] is required in this situation. For proper
operation, make certain the check valve is oriented as instructed.
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.

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 resume normal operation. To reset this delay without
waiting 12 hours momentarily unplug the pump.
Electrocution Hazard! Pump starts automatically. Disconnect the power before
attempting any repairs. Failure to follow will result in serious injury or death.
Corrective Action
1. Reset breaker
2. Check for damaged wiring or moisture
3. If voltage is under 108 volts, check wiring size
4. Replace pump
5. Rinse out switch with clean water (Figure 3 on page 3)
6. Remove base and impeller plate (Figure 2 on page 3) check for
debris; clean
7. Clean inlet screen (Figure 2 on page 3)
8. Clean hole, inside volute housing, with a pin or paper clip (Figure
2 on page 3)
1. Install or replace check valve [Sold Separately: 62061-001]
2. Rinse out switch with clean water (Figure 3 on page 3)
3. Clean hole, inside volute housing, with a pin or paper clip
(Figure 2 on page 3)
1. Rinse out switch with clean water (Figure 3 on page 3)
2. Raise pump or reduce discharge height
1. Remove base and impeller plate (Figure 2 on page 3), check for
debris; clean
2. Clean hole, inside volute housing, with a pin or paper clip
(Figure 2 on page 3)
3. Check for kinks, reposition hose or check for debris
4. Reposition pump to reduce discharge height
