4. Einrichtung und Installation
Proper installation is critical for the performance and safety of your filter system.
- Standort: Place the filter system on a firm, level surface, preferably concrete, as close to the pool as possible. Ensure adequate ventilation and protection from direct sunlight and extreme weather.
- Montage:
- Attach the pump to the base plate.
- Place the filter tank onto the base plate.
- Connect the pump to the filter tank inlet.
- Install the multi-port valve onto the top of the filter tank, ensuring a secure, watertight seal.
- Attach the pressure gauge to the multi-port valve.
- Filter Media (Sand) Installation:
- Remove the multi-port valve from the tank.
- Cover the standpipe opening inside the tank to prevent sand from entering.
- Carefully pour the recommended amount and grade of filter sand (e.g., #20 silica sand) into the tank. Refer to the specifications for the correct quantity.
- Level the sand and remove the standpipe cover.
- Reinstall the multi-port valve, ensuring it is properly seated and sealed.
- Sanitäranschlüsse:
- Connect the pool skimmer/main drain line to the "PUMP" port on the multi-port valve.
- Connect the pool return line to the "RETURN" port on the multi-port valve.
- Connect a waste line to the "WASTE" port on the multi-port valve, directing it to an appropriate drainage area.
- Stellen Sie sicher, dass alle Verbindungen dicht und dicht sind.
- Elektrischer Anschluss:
- Connect the pump to a properly grounded electrical outlet or circuit, protected by a Ground Fault Circuit Interrupter (GFCI).
- Stellen Sie sicher, dass die Lautstärketage und Frequenz entsprechen den Anforderungen der Pumpe.

5. Bedienungsanleitung
The multi-port valve controls the flow of water through the filter system. Always turn off the pump before changing the valve position to prevent damage.
Multi-Port Valve Positions:
- FILTER: Normal filtering operation. Water flows through the sand bed, trapping debris, and returns to the pool. This is the most common setting.
- RÜCKSPÜLUNG: Used to clean the filter sand. Water flows in reverse through the sand bed, dislodging trapped debris, and is directed out the waste port. Backwash until the sight glass (if present) runs clear.
- SPÜLEN: Used after backwashing to settle the sand bed and flush any remaining dirty water to waste. Run for 30-60 seconds.
- ABFALL/ABFLUSS: Bypasses the filter and sends water directly out the waste port. Useful for vacuuming heavy debris directly to waste or lowering pool water level.
- UMKEHREN/UMGEBEN: Bypasses the filter and circulates water directly back to the pool. Useful for distributing chemicals without filtering.
- GESCHLOSSEN/WINTERISIEREN: Closes all ports to the filter. Use for servicing the pump or filter, or for winterizing the system. Never operate the pump in this position.
Starten des Systems:
- Ensure the pool is filled to the proper level.
- Prime the pump if necessary (fill the pump basket with water).
- Stellen Sie das Mehrwegeventil auf „RÜCKSPÜLEN“.
- Turn on the pump and backwash for 2-3 minutes or until the water in the sight glass is clear.
- Schalten Sie die Pumpe aus.
- Stellen Sie das Mehrwegeventil auf „SPÜLEN“.
- Pumpe einschalten und 30-60 Sekunden lang spülen.
- Schalten Sie die Pumpe aus.
- Set the multi-port valve to "FILTER".
- Turn on the pump. Note the initial pressure gauge reading. This is your clean filter pressure.

6. Wartung
Regular maintenance ensures efficient operation and extends the life of your filter system.
- Rückspülen: Backwash the filter when the pressure gauge reading is 8-10 PSI (0.5-0.7 bar) above your clean filter pressure, or when pool water appears cloudy.
- Reinigung des Pumpenkorbs: Regularly inspect and clean the pump strainer basket. Turn off the pump, close necessary valves, remove the lid, empty debris, and replace.
- Filtersandwechsel: Filter sand typically lasts 3-5 years, depending on usage and water chemistry. Replace the sand when filtration efficiency decreases despite regular backwashing.
- Überwinterung: In cold climates, drain all water from the pump, filter, and plumbing lines to prevent freezing damage. Store the multi-port valve handle in the "WINTERIZE" or "CLOSED" position (if available) or remove it and store indoors.
- Dichtheitsprüfung: Periodically check all connections for leaks and tighten as necessary.
7. Fehlerbehebung
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Low water flow / Low pressure | Clogged skimmer/pump basket, dirty filter sand, air leak in suction line, pump not primed. | Clean baskets, backwash/rinse filter, check for air leaks, prime pump. |
| Trübes Poolwasser | Dirty filter sand, insufficient filtration time, improper water chemistry, broken laterals inside filter. | Backwash/rinse, run filter longer, balance chemicals, inspect laterals (requires draining sand). |
| Water leaking from valve | Worn O-rings/gaskets, loose connections. | Inspect and replace O-rings/gaskets, tighten connections. |
| Pumpe läuft nicht | No power, tripped breaker/GFCI, motor issue. | Check power supply, reset breaker/GFCI, consult a qualified electrician. |
