The SandPRO 50D features an easy-to-operate 4-position rotary valve for various functions:

Imatge: Una imatge detallada view of the multi-port valve with its 4-way handle, the integrated pressure gauge, and the transparent lid of the strainer basket.
- FILTRE: This is the standard operating mode for daily filtration. Water is pumped through the sand bed, trapping debris, and returned to the pool.
- CONTRENAT: Used to clean the sand filter. Water flow is reversed, flushing trapped debris out through the waste port. Perform backwash when the pressure gauge reading increases by 5-10 PSI above its clean operating pressure.
- ESbandida: After backwashing, this mode settles the sand bed and flushes any remaining dirty water to waste before returning to FILTER mode.
- hivernar: Prepares the filter for off-season storage. Consult the user guide for specific winterization procedures.
The integrated pressure gauge allows you to monitor the filter's performance. A rising pressure indicates that the filter media is becoming clogged and requires backwashing.

- Cistella de colador: Periodically check and clean the large-capacity easy-to-clean hair & debris strainer basket. The see-through lid allows for easy inspection. Turn off the pump before opening the basket.
- Backwashing & Rinsing: Perform backwashing and rinsing as needed, typically when the pressure gauge indicates a 5-10 PSI increase from its clean operating pressure.
- Substitució de sorra: The #20 silica sand typically needs replacement every 3-5 years, depending on usage and water quality. Refer to the user guide for instructions on replacing the sand.
