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.
Maintenance and Inspection
• Regular maintenance and inspections are a necessity for
continued efficient functioning. If any abnormal conditions are
noticed, refer to the section on Troubleshooting and take corrective
measures immediately.
• During or after the warranty period, the customer is NOT to
disassemble the pump for any reason.
Monthly Inspection
• Check for any drop in performance. Reduced performance is usually
caused by debris blocking the intake screen.
• Detach the power cable from the receptacle and turn off the power
supply (circuit breaker).
• Disconnect the pump discharge and remove the pump from
the water.
• Remove any accumulated debris from the surface of the pump, inlet
screen and impeller.
• Make sure all nuts and bolts are fastened securely.
• Do not disassemble the pump for any reason. Disassembly will void
the pump warranty. Refer operating and maintenance problems to a
qualified technician.
