Before You Start
• Check the model name plate to make sure once again that the product is of the correct
voltage and frequency rating.
• The setting on the circuit breaker or other overload protector should be made in
accordance with the rated currency of the pump.
• Turn off the power supply or circuit breaker before inserting the power supply plug to
avoid electrical shock, shorting, or unexpected starting of the pump, which could lead
to injury.
• Never operate the pump while it is suspended in air. The recoil may result in injury or
other major accident.
Electrical Safety
• Electrical wiring should be installed by a qualified electrician in accordance with all
applicable safety regulations. Incorrect wiring can lead to a pump malfunction, electrical
shock or fire.
• Pumps should operate on a designated, circuit rated at 15 Amps (minimum).
• Pump must be protected by a ground fault circuit interrupter (GFCI).
• Pump must be plugged into a standard, properly grounded, three pronged outlet.
• Do not cut the electrical cable. If a cable with cut insulation or other damage is submerged
in water, there is danger of water seeping into the pump motor and causing a short. This
may result in damage to the pump, electrical shock or fire.
Altering the electrical cable in
any way will void the warranty.
• Never move or handle the pump by pulling on the electrical cable. Make sure the electrical
cable does not become excessively bent or twisted, does not rub against a structure in a
way that might damage it, and does not come in contact with heated surfaces.
Operation
• In case of a power outage, turn off the power to the pump to avoid having it start
unexpectedly when the power is restored.
• L-Series pumps are cooled internally as the water flows around the motor.
Entire pump
including intake screen must be completely submersed during operation.
• In case of very excessive vibration, unusual noise or odor, turn off the power immediately and
consult with your nearest dealer. Continuing to operate the pump under abnormal
conditions may result in electrical leakage, electrical shock or fire.
Motor Protection System
• The pump has a built-in motor protection system. The following reasons may cause the
pump to stop automatically regardless of water level.
• Motor overheating
• Excessive current
• Change in voltage polarity
• Open-phase operation or operation under constraint
• Repeating cycles of stopping and restarting will damage the water pump. Do not
continue operation at low lift, low water level, or while the inlet is clogged with debris.
Not only will performance suffer, but also such conditions may cause noise, heavy
vibration, and pump failure.
