Hayward  - ProSeries™ Sand Filters

Product Description


ProSeries™ high-rate sand filters are high performance, totally corrosion-proof, unitised tank constructed filters that blend superior flow characteristics and features with ease of operation. For multiple applications, the ProSeries™ represents the very latest in sand filter technology and will provide clear, sparkling water for years to come.







Set valve to FILTER for normal filtering. Also use for regular vacuuming.


For cleaning filter. When filter pressure gauge rises 8-10 PSI (0.55-0.69 BAR) above start-up (clean pressure):
Stop the pump, set valve to BACKWASH. Start pump and backwash until water in sight glass is clear. Approximately 2 minutes or less depending on dirt accumulation. Proceed to RINSE. 



After backwashing, with pump off, set valve to RINSE. Start pump and operate for about 1/2 to 1 minute. This ensures that all dirty water from backwashing is rinsed out of the filter to waste, preventing possible return to the pool. Stop pump, set valve to FILTER, and start pump for normal filtering.



To bypass filter for draining or lowering water level and for vacuuming heavy debris directly to waste.



Water is recirculated through the pool system, bypassing the filter.



Shuts off flow from pump to filter. VACUUMING—Vacuuming can be performed directly into the filter. When vacuuming heavy debris loads, set valve to WASTE position to bypass the filter and vacuum directly out to waste.



Pure, clear swimming pool water is a combination of two factors—adequate filtration and proper water chemistry balance. One without the other will not give the clean water you desire.


Your filter system is designed for continuous operation. However, this is not necessary for most swimming pools. You can determine your filter operation schedule based on your pool size and usage. Be sure to operate your filtration system long enough each day to obtain at least one complete turnover of your pool water.


To properly sanitize your pool, maintain a free chlorine level of 1 to 3 ppm and a pH range of 7.2 to 7.6. Insufficient chlorine or an out of balance pH level will permit algae and bacteria to grow in your pool and make it difficult for your filter to properly clean the pool water.


*NOTE: For new concrete pools, or where there is a large amount of dust or debris—start filter in FILTER position (not BACKWASH) to prevent clogging of underdrain laterals. 






  1. Check skimmer and pump strainer baskets for debris.

  2. Check for restrictions in intake and discharge lines.

  3. Check for air leak in intake line (indicated by bubbles

  4. returning to pool).

  5. Backwash filter. 




  1. Check for algae in pool and treat as required.

  2. Be sure chlorine and pH levels are in proper range (adjust as required).

  3. Check surface of filter sand for crusting or caking (remove 1 " of sand if necessary). 




  1. Check chlorine, pH and total alkalinity levels and adjust as required.

  2. Be sure flow rate through filter is sufficient.

  3. Operate filter for longer periods.

  4. Be sure Vari-Flo valve is set on "Filter" position.
