5. Operating Instructions

5.1. 6-Way Multiport Valve Functions

The 6-way valve allows you to control the water flow through the filter system. Always turn off the pump before changing valve positions.

• FILTER: Standard operating mode for daily filtration. Water passes through the sand media, cleaning the pool water.
• BACKWASH: Reverses water flow through the filter to clean the sand media. This flushes trapped debris out through the waste port.
• RINSE: Used after backwashing to flush out any remaining debris from the filter lines before returning to FILTER mode.
• WASTE: Bypasses the filter and sends water directly out the waste port. Useful for lowering pool water level or vacuuming heavy debris directly to waste.
• CIRCULATE: Bypasses the filter and circulates water directly back to the pool. Useful for mixing chemicals without filtering.
• CLOSED: Stops all water flow to and from the filter. Never use this setting while the pump is running.

5.2. Timer Settings

The integrated timer allows for automated filtration cycles. The pump offers 9 time settings from 2 to 24 hours, with options for single or continuous cycles.

1. Set Running Hours: Select the desired filtration duration using the timer dial.
2. Activate Timer: Turn on the pump. The time of activation will become the daily start time for the selected cycle.
3. Continuous Operation: For continuous operation, select the appropriate setting or bypass the timer function if available.

6. Maintenance

Regular maintenance ensures optimal performance and longevity of your AQUASTRONG sand filter pump.

• Backwashing: Backwash the filter when the pressure gauge reads 8-10 PSI above its clean operating pressure, or when water clarity decreases.
  1. Turn off the pump.
  2. Set the 6-way valve to 'BACKWASH'.
  3. Turn on the pump and backwash until the water in the sight glass (if present) runs clear (typically 2-3 minutes).
  4. Turn off the pump.
  5. Set the 6-way valve to 'RINSE'.
  6. Turn on the pump and rinse for 30-60 seconds.
  7. Turn off the pump.
  8. Set the 6-way valve to 'FILTER' and restart the pump for normal operation.
• Sand Replacement: Filter sand typically needs replacement every 3-5 years, depending on usage and water quality.
• Pump Basket Cleaning: Periodically check and clean the pump's strainer basket to remove large debris.
• Winterization: In colder climates, drain all water from the pump and filter system to prevent freezing damage. Store the pump in a dry, protected area.
