Reactivation Instructions
When the blue silica gel beneath the inspection window turns pink, reactivate as follows: Place the unit in a 145°C oven for at least 3 hours. (or until the silica gel turns blue again.) Remove from oven and let cool until able to handle. Keep in sealed container until ready to use.
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.
