Installation Process

Installing your new 9902 fridge filter may seem like a daunting process at first, but it can be done in a matter of minutes. Find your water filter cartridge typically located at the bottom of your refrigerator in the grille.  If you are having trouble locating your filter cartridge, try looking in the upper right corner inside of the fridge or on the back of the fridge.  Replace your filter whenever the indicator light on the cartridge turns red, or if the water flow to the dispenser decreases.  Follow these steps to replace your fridge filter:

  1. Turn off icemaker
  2. Remove your old filter by rotating the filter cap about ¼ of a turn counter-clockwise
  3. Pull out the old filter cartridge
  4. Remove the cartridge grille cap by sliding it off the end of the old cartridge
  5. Slide the cartridge grille cap onto the new filter cartridge
  6. Once the new cartridge cap is in the vertical position, insert the new filter cartridge into the base grille
  7. Rotate the cap clockwise into a horizontal position

Remember to flush three to five gallons of water through the new filter cartridge before use. Once this is completed, you can turn your icemaker back on. Now you will be able to enjoy clean, better-tasting water at your leisure.

Filtration- How It Workswater filtered by 4396508

Now that you have your filter installed, you can enjoy clean, clear drinking water all of the time.  How does your 9902 filter accomplish this? The answer is activated carbon.  Activated carbon is an extremely porous form of carbon that is exceptional at capturing particles.  Using this as a filtration tool inside your water filter allows the filter to capture undesirable substances such as lead, mold, bacteria, cysts, and chlorine that may be present in your tap water.

As water enters the filter chamber, it gets pushed through a central chamber filled with activated carbon.  The carbon will filter out any unwanted particles, producing clean, healthy water. This water is then pushed back out of the filter and is available for drinking.  This entire process occurs in a matter of seconds!

Filter Change Reminder

Unfortunately, filters don’t last forever. If you want to continue having access to clean, better-tasting drinking water, it is important to perform routine filter changes when necessary.  A filter undergoing continual use over time will begin to degrade as more and more water passes through it.  This can lead to a drop in water quality as the filter loses its efficacy.  This can be easily prevented by changing your filter at least once every six months so that you never have to worry about drinking dirty water ever again.
