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 sub-
mersible type and must be in water at all times for prop-
er operation and cooling.
Periodically clean the pump inlet. This will avoid
impeller rotation being hampered by any debris.

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.
