Installation and general maintenance manual
SOLUTION
•
Power cut. Check the circuit breakers.
•
Check the connection between the power cable and the motor' s terminals.
•
Check that the motor shaft is turning freely. Check that there is no debris
in the strainer basket.
•
If any debris still remains, remove the pump to access the turbine.
•
Check the position of the valves in the hydraulic circuit.
•
Air has clogged up in the circuit. Bleed the hydraulic circuit (bleed valve
on the filter).
•
The pool' s water level is too low, so the circuit is sucking in air. Fill the pool.
•
The strainer lid is defective. Check the state of repair of the gasket and that
the lid is watertight.
•
The strainer basket is full of debris. Clean it.
•
Air leak in the circuit. Check all of the tightening torques.
•
The turbine and pump diffuser are blocked or worn. Replace them.
•
The diffuser' s gasket is worn. Replace it.
•
Reverse rotation of the motor (only on three-phase pumps). Check the
connections of pump' s terminal blocks.
•
The filter is blocked up. Clean the filter (or cartridge, as may be the case).
•
Check the position of the valves in the hydraulic circuit.
•
Air leak or cavitation in the suction piping. Check the position of the valves
and adjust them whenever necessary.
•
Pump badly placed on the ground. Check that it is on a flat, hard, horizontal
surface. Use anti vibration pads whenever necessary.
