• 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 / Cleaning
• 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.
• Remove the pre-filter, inspect the adjustable flow and remove any accumulated debris.
• Remove the threaded inlet cover by rotating it in a counterclockwise half turn while pulling
lightly outward from the pump body.
• Inspect the impeller and remove any debris that may be present.
• Spin the impeller. If the impeller is difficult to turn, feels “gritty”, or a grinding noise is
evident in the rotor chamber, remove the rotor as per the instructions below.
Removing the Rotor
• Remove the impeller assembly by pulling outward from the rotor chamber.
Note:
The impeller assembly is comprised of six individual parts shown in the image below.
Take care not to lose or misplace any of these pieces during the cleaning process.
