4. Assemblage et installation
Follow these steps for proper assembly and installation of your filter pump. Refer to your pool's specific instructions for connecting the hoses to the pool's inlet and outlet ports.
- Positionner la pompe : Place the filter pump on a solid, level surface, at least 2 meters (6.5 feet) away from the pool edge. Ensure the pump is lower than the pool's water level.
- Connecter les tuyaux : Attach one hose from the pump's inlet port (marked with a minus sign or 'IN') to the pool's water outlet (suction) port. Attach the second hose from the pump's outlet port (marked with a plus sign or 'OUT') to the pool's water inlet (return) port. Secure all hose connections with clamps.
- Install Strainers: Insert the inlet and outlet strainers into the corresponding ports inside the pool.
- Assurer le débit d'eau : Open any valves or plugs on the pool's inlet and outlet ports to allow water to flow into the pump. The pump housing should fill with water.
- Purge d'air : Loosen the air release valve on top of the filter pump housing until water starts to flow out. Close the valve once all air has escaped.
- Connexion électrique : Plug the pump into a properly grounded electrical outlet protected by a GFCI/RCD.
5. Fonctionnement
The Bestway Flowclear filter pump is designed for ease of use, featuring an energy-saving plug with a built-in timer for customizable operation.
- Démarrage de la pompe : After ensuring proper installation and water flow, plug the pump into the electrical outlet. The pump will begin to operate.
- Réglage de la minuterie : The energy-saving plug allows you to set the pump to run for a specific duration, up to 10 hours. Consult the instructions provided with the plug for detailed timer setting procedures. This feature helps optimize filtration cycles and energy consumption.
- Fonctionnement quotidien: For optimal water clarity, operate the filter pump daily. The duration of operation depends on pool size, bather load, and environmental conditions. A general guideline is to run the pump for at least 8-10 hours per day.
- Arrêt de la pompe : Pour éteindre la pompe, il suffit de la débrancher de la prise électrique.
6. Entretien
Regular maintenance of your filter pump is crucial for its longevity and for maintaining clean pool water. The primary maintenance task involves cleaning or replacing the filter cartridge.
- Débrancher l'alimentation : Always unplug the filter pump from the electrical outlet before performing any maintenance.
- Fermer les vannes : Close the pool's inlet and outlet valves (if applicable) to prevent water from flowing out of the pool.
- Remove Filter Housing Lid: Unscrew the collar retainer and remove the filter housing lid.
- Retirer la cartouche : Carefully remove the used Type III-A/C filter cartridge from the pump housing.
- Nettoyer ou remplacer :
- Nettoyage: Rinse the filter cartridge thoroughly with a garden hose to remove debris. If the cartridge remains dirty or discolored after rinsing, it should be replaced.
- Remplacement: Install a new Bestway Type III-A/C filter cartridge into the pump housing.
- Remonter: Place the filter housing lid back on and tighten the collar retainer securely.
- Restaurer l'alimentation : Open the pool's valves, bleed any air from the pump (as described in Section 4), and plug the pump back into the electrical outlet.
