 Always disconnect from the electrical outlet before handling the Pump. 

 
IF THE PUMP FAILS TO OPERATE, CHECK THE FOLLOWING:

 

 

• 

Check the circuit breaker and try another GFCI protected outlet to ensure the Pump is 
getting electrical power. 

 

• 

Check the pump discharge, impeller and tubing for obstructions. 

 

• 

Check the intake screen to ensure it is not clogged. 

 

• 

Flush with water to remove any algae build-up. 

 

• 

To clean the Impeller area: rotate the volute 45º counter-clockwise and pull it straight out. 
Rotate the impeller by hand to ensure that it can spin freely. 

 

• 

Use a stream of water to remove any debris. 

 

• 

Monthly maintenance will add to your Pump’s life.
