Replacing Your Water Optimizer’s Filters
Your Water Optimizer is equipped with a 
I
 Pod Filter(s) Status Light

This reminder 
is controlled by a timer that will change the Pod Filter(s) Status Light
 from white to red 
every six months. This timer can be reset by following the last step in this section.
To maximize lter and appliance lifespan, it is very important to always ush the
