5. Pump can run when water doesn’t completely cover the
motor housing, but the inlet must be completely sub-
merged or it will break suction, will not move any water,
and may damage the shaft seal.
NOTICE:
For continuous operation the water depth must be
at least 5” (13 cm) to prevent the pump from overheating.
6. Keep the pump inlet clean at all times. If the ground bot-
tom or surface where the pump sits is dirty, raise the
pump slightly to reduce the amount of debris pulled into
the pump inlet.
7. If you need to reduce the flow, restrict the discharge. Do
not restrict the intake. Doing so will starve the pump for
water and can cause overheating.
MAINTENANCE
Risk of electric shock. Can burn or cause
death.
Disconnect the power before servicing, repairing, or
working on pump.
The pump’s motor is completely sealed in the motor housing
and does not require any service. Disassembly of the motor
housing or modification or removal of the power cord voids
the warranty. The power cord is non-replaceable.
Never run the pump dry! Running the pump dry can damage
the seal, causing leakage. This pump is a submersible type and
must be in water at all times for proper operation and cooling.
Periodically clean the pump inlet. This will avoid impeller rota-
tion being hampered by any debris.
To Clean Inlet/Impeller
1. Unplug pump.
2. Remove baseplate by turning in direction of OPEN arrow.
Clean out inlet.
3. Remove screw holding volute base to pump housing.
4. Turn volute base in direction of OPEN arrow and remove.
Clean out impeller.
To reinstall, reverse above directions. Be sure to replace
O-Ring and engage volute base tabs with pump housing before
replacing screw.
TROUBLESHOOTING
NOTICE:
This pump has no serviceable parts inside the motor
housing. Opening the motor housing will ruin the pump. If
obstructions or blockages of the impeller cannot be cleaned
out as described above, or by backflushing into the discharge
with a garden hose, replace the pump.
Hazardous voltage; can shock, burn or kill.
Unplug the pump before attempting to clean or work on the
pump.
