7.2. Backwash Mode

Backwash Mode is used to clean the sand filter by reversing water flow, flushing out dirt and debris. Activate this mode by selecting the appropriate setting on the control panel. The pump will reverse the water flow, directing dirty water through the waste port. Regular backwashing ensures optimal filter performance and prevents clogging. Perform this mode when pressure gauge readings indicate high pressure or reduced flow. Always connect the waste hose securely before starting Backwash Mode. After backwashing, return the valve to Filter Mode to resume normal operation. This process is essential for maintaining clean water and extending the lifespan of the sand filter. Ensure the waste water is directed to an appropriate drainage area to avoid environmental contamination. Proper use of Backwash Mode keeps your pool water clean and your filtration system functioning efficiently. Regular backwashing also helps prevent premature wear on the pump and filter components. Always refer to the manual for specific instructions on when and how to perform this maintenance task. By following these steps, you can keep your pool water clear and your filtration system in peak condition.
