5. Instrukcja obsługi

The 5-way selector valve on top of the filter tank controls the various functions of the system. Aby zapobiec uszkodzeniom, przed zmianą położenia zaworu należy zawsze wyłączyć pompę.

• FILTR: This is the standard operating mode for daily pool water filtration. Water passes through the filter media, removing impurities, and then returns to the pool.
• PŁUKANIE WSTECZNE: Used to clean the filter media. Water flows in reverse through the filter, dislodging trapped debris, and is then directed out through the waste port. Perform backwash when the pressure gauge reads 0.2-0.3 bar (3-5 psi) above its clean operating pressure.
• WYPŁUKAĆ: Used after backwashing to flush out any remaining dirty water from the filter and settle the filter media. Water flows through the filter and out the waste port.
• ODPAD/ODPROWADZANIE: This setting bypasses the filter and sends water directly from the pool out through the waste port. Useful for draining the pool or vacuuming heavy debris directly to waste.
• RECYRKULUJ: Water is circulated through the system and back to the pool without passing through the filter media. Useful for mixing chemicals without filtering.
• ZAMKNIĘTE: This position shuts off all flow to and from the filter. Use this setting only when the pump is off and for maintenance tasks that require isolating the filter.
