Reactivation Instructions
When the center circle turns pink reactivate the unit as follows: Remove the bag of silica gel from the carton and place into a 115°C oven for at least 3 hours. Once reactivated, remove bag from the oven and let cool until able to handle. Replace the bag in the carton and store in a sealed container until ready to use. (It may take several hours for the indicating circles to turn blue again.)

Please Note: When you first use the Silica Gel Canister in a particular area, it may become saturated rather quickly as it adsorbs residual moisture. Once the residual dampness is removed, you can maintain a dry condition with less frequent need to reactivate.
