SO-204 CARTRIDGE 9105-45


  • 20" large capacity softening system for espresso machines reduces scale-forming minerals like calcium and magnesium
  • Reduces scale forming minerals by ion exchange
  • May be used on water having up to 30 grains per gallon (500 mg/L) hardness
  • Useful where full size water conditioners are impractical
  • Includes mounting bracket, pressure relief valve and filter wrench
  • Recommended to be used in conjunction with an Everpure filtration system


Installation Tips

  • Choose a mounting location suitable to support the full weight of the system when operating
  • Use 1" water line
  • Install vertically with bowl hanging down
  • Allow 2-1/2" clearance below the cartridge for easy cartridge replacement
  • Flush cartridges by running water through for one minute at full flow
  • Make sure O-ring on bowl is sufficiently lubricated
  • Always screw on bowls by hand; Do not use a housing wrench


Operation Tips

  • Change cartridges on a regular 6 month preventative maintenance program
  • Change cartridges when hardness of treated water increases to more than 3 gpg
  • Service flow rate must not exceed 2.0 gpm
  • Always flush the cartridge at time of installation and cartridge change
  • To determine cartridge life, divide total capacity of cartidge (4,400 grains) by the hardness in grains per gallon (gpg) or milligrams per liter (ppm), respectively
