Procedures for Conditioning FilterBalls™ for First Time Use:

VERY IMPORTANT INFORMATION,PLEASE READ BEFORE PROCEEDING
-Not recommended for underdrains that use perforated cylinders
-Recommended for use in underdrains that use laterals for effective use of filtration media

  1. FilterBalls™ products (Green™, Blü™, Blü10™ or Sanž™) are for use in housings rated above 250 pounds of #20 filter sand.
  2. Minimum bed depth of 12" above laterals, (see above) being sure to leave at least 30% open space above media for proper backwashing.
  3. Minis should always be used when the media bed depth is 12" or less indepth. Generally these are sand vessels rated at 250 pounds or less.
  4. FilterBalls Minis™ performance is not warranted in sand housings rated under 150 pounds of #20 filter sand. Many pump filter combos in this range are not hydraulically balanced. A two or variable speed pump is the exception. Please consult with a qualified pool technician for proper filter and pump system configurations for your pool.

Directions for start-up (empty tank, system off):

  1. Remove filter sand (if current vessel has sand in it).
  2. Clean the sand particles that might be jammed in the lower underdrain laterals.
  3. Add FilterBalls™ to tank (they are soft and can be pressed down when filling).
  4. Replace control valve or tank lid and rinse the new media for 2 minutes, then backwash for 2 minutes.
  5. Set to filter mode.
  6. Backwash again when pressure increases by 5-7 PSI.
