Installation


  • Turn off the water supply before starting.
  • Install the filter cartridge in cold water applications only.
  • Connect the filter to the compatible Haws unit (2000S, 2000SN, 2010, etc.) following local plumbing codes.
  • After installing a new cartridge, run at least 5 gallons of water through the system to flush out carbon particles and air bubbles.
  • Check all connections for leaks before regular use.
  • For detailed steps, refer to the installation manual provided in the package or contact a licensed plumber.


Maintenance


  • Replace the filter every 12 months or after 2,500 gallons, whichever comes first.
  • Monitor water flow; if it slows down, replace the cartridge sooner.
  • Inspect fittings regularly to ensure there are no leaks.
  • Only use genuine Haws replacement filters for certified performance.
  • For service or repairs, consult the manual or a licensed technician.
