- Oinarria muntatzea: Attach the pump and filter tank to the base support as per the included diagrams.
- Add Filter Media: Remove the multi-port valve and carefully pour the recommended amount of filter sand (70 lbs) or filter balls (2.2 lbs) into the tank. Ensure the standpipe is centered during this process.
- Install Multi-Port Valve: Place the 7-way valve onto the filter tank, ensuring the O-ring is properly seated. Secure with the flange clamp.
- Connect Pump to Filter: Attach the pump to the filter tank using the provided hose and clamps.

5. Funtzionamendu-argibideak
The 7-way multi-port valve allows for various operational modes. Always turn off the pump before changing the valve position.
- Iragazkia: This is the standard operating mode for daily filtration. Water passes through the filter media, and clean water returns to the pool.
- Atzera-garbiketa: Used to clean the filter media. Water flow is reversed, flushing accumulated debris out through the waste port. Perform when pressure gauge reads 8-10 PSI above starting pressure.
- GARBITU: Used after backwashing to flush any remaining debris from the valve and filter lines to the waste port, preventing it from returning to the pool.
- HONDAKINAK: Bypasses the filter and sends water directly out the waste port. Useful for lowering pool water level or vacuuming heavy debris directly to waste.
- ITXITA: Shuts off all flow to the filter and pump. Never use this setting while the pump is running.
- BIRKIRKULATU: Iragazkia saihestu eta ura zuzenean igerilekura itzultzen du. Produktu kimikoak iragazi gabe nahasteko erabilgarria.
- NEGUA: Position for winterizing the filter system.

6. Mantentzea
Regular maintenance ensures optimal performance and extends the life of your filter pump.
- Atzera-garbiketa eta ureztatzea: Perform backwashing when the pressure gauge indicates a rise of 8-10 PSI above the clean filter pressure. Follow with a rinse cycle.
- Iragazki-saskiaren garbiketa: Regularly inspect and clean the pump's strainer basket. Turn off the pump, close necessary valves, remove the clear cover, empty debris, and replace.
- Iragazki-euskarriaren ordezkapena: Sand filter media typically lasts 3-5 years. Filter balls may require cleaning or replacement more frequently depending on usage.
- Neguan egitea: Before freezing temperatures, drain all water from the pump, filter, and hoses. Store the pump and filter in a dry, protected area.
