When the indicator crystals turn Pink it is time to "re-new" the unit. Simply remove the unit from where it is adsorbing moisture and plug it into a power outlet in a well ventilated area (bathroom with extraction fan, garage, outside, etc.). There is a built-in heater that will warm the crystals allowing them to expand and release the moisture as water vapor into the outside air. It takes about 8 hours to completely re-new the unit. When it is completely renewed the indicator crystals will change back to blue. The unit is brand new again and ready to adsorb another 6 ounces of moisture.
The crystals will remain active for 10 years and we offer a 5 year limited manufactures warranty on all EDV300 units.NO LONGER AVAILABLE
