MAINTENANCE AND TROUBLESHOOTING (CONTINUED)

IMPELLER PLATE BASE SCREWS (4)

INLET SCREEN/

BASE

PRIMING HOLE

WHEN REATTACHING THE BASE (INLET SCREEN), BE SURE THAT THE FOUR (4) "PLUGGED" SCREENS 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.

Symptom	Possible Cause(s)
Pump will not	1. Tripped home electrical breaker
start or run	2. GFCI tripped
	3.	Low line voltage
	4.	Defective motor
	5.	Dirty switch
	6.	Impeller obstructed
	7.	Inlet screen clogged
	8.	Priming hole plugged
Pump starts and	1. Backflow of water from piping
stops too often	2. Dirty switch
	3.	Priming hole plugged

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: CAT No. 40138]

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)

Pump will not	1.	Debris in switch	1.	Rinse out switch with clean water (Figure 3 on page 3)
shut off or runs	2.	Discharge height exceeds capability	2.	Raise pump or reduce discharge height
continuously
Pump operates	1.	Impeller obstructed	1.	Remove base and impeller plate (Figure 2 on page 3), check for
but delivers little				debris; clean
or no water	2.	Priming hole plugged	2.	Clean hole, inside volute housing, with a pin or paper clip
				(Figure 2 on page 3)
	3.	Obstructed piping	3.	Check for kinks, reposition hose or check for debris
	4.	Discharge height exceeds capability	4.	Reposition pump to reduce discharge height
