- Ensure the pool water level is adequate for safe operation.
- Activate the main power switch for the countercurrent system.
- Press the ON button on the control panel, typically located near the pool or on the nozzle unit itself. The pump will start, and water will begin to flow from the nozzle.
Stopping the System:
- Press the OFF button on the control panel. The pump will stop.
- For extended periods of non-use, or during maintenance, turn off the main power switch to the system.
Regolazione del flusso:
Some models may feature adjustable nozzle settings to vary the intensity or direction of the countercurrent. Refer to the specific nozzle documentation for adjustment procedures.
6. Manutenzione
Regular maintenance ensures the longevity and optimal performance of your countercurrent system.
Manutenzione ordinaria:
- Ispezionare l'ugello: Periodically check the nozzle for any debris or blockages. Clean as necessary.
- Controllare la pompa: Listen for unusual noises from the pump. Ensure there are no visible leaks around the pump or plumbing connections.
