These will notify you when it is time to perform routine filter replacement. Be sure to reset the filter life indicator every time you replace a filter (see Filter Replacement Guide” below for instructions).
Filter Replacement Guide:
Before replacing a filter, turn off the cold and hot water supplies under the sink, then open the faucet to fully release the water pressure on the system. Wait 3-5 minutes and then unplug the power cord to the RO filtration unit.
a. Remove the front cover of the RO filtration unit.
b. Twist the filter that needs to be replaced counterclockwise until the triangle symbol on the filter is aligned with the “unlocked” symbol on the filter housing.
c. Remove the old filter by pulling it straight out. Note that a small amount of residual water will flow out when the old filter is removed. Use a clean towel to wipe up any remaining water inside the empty filter housing.
d. Remove wrappings and protective cap from the new filter.
e. Insert the new filter into the corresponding filter hole, aligning the triangle symbol on the filter with the “unlocked” symbol on the housing, then rotate 90° clockwise until the triangle symbol is aligned with the “locked” symbol on the housing. You may hear a click when the filter is in place.
f. After the filter is in place, plug the power cord back into its outlet and turn the water supply back on. Press and hold the filter Reset button for 3 seconds to enter the filter reset program, then tap the selection key to select the desired filter. Press the Reset button again for 3 seconds until you hear the system beep. The filter is now successfully reset.
