• Mag Drive Series pumps must not be used to pump salt water, sewage, flammable or
corrosive liquids, greases, oils or food waste.
• Pay careful attention to the water level while the pump is operating. The pump must be
fully submersed at all times of operation.
• Repeating cycles of stopping and restarting will damage the water pump. Do not continue
operation at low water level or while the inlet is clogged with debris. Not only will perfor-
mance suffer, but also such conditions may cause noise, heavy vibration, and pump failure.
• In case of excessive vibration, unusual noise or odor, turn off the power immediately and
consult your nearest dealer.
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.
Monthly Inspection
• Check for any drop in performance. Reduced performance is usually caused by debris
blocking the pump intake.
• Detach the power cable from the receptacle or 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 and pre-filter.
• Unthread the pre-filter by turning it in a counter clockwise direction. Inspect the threaded
inlet on the volute and remove any accumulated debris.
• Remove volute by rotating it in a counterclockwise half turn while pulling lightly outward
from the pump body.
• Inspect the impeller. The impeller should spin freely. If the impeller feels tight or gritty
when spun, please refer to the cleaning instructions on page 5.
Winterizing
• Under no circumstances should the pump be left in frozen water.
• When the pump is out of use for an extended period, wash it and dry it thoroughly, then
store it indoors.
Note: Always run a test operation before putting the pump back into operation. When the
pump is left installed in water it should be run at regular intervals (about once per week).
