- Multiple Units: For larger spaces or areas with consistently high humidity, consider using multiple dehumidifier stones to achieve optimal moisture control.

3. Operating Instructions
The Hornady Rapid Dry Dehumidifier Stone operates passively by absorbing moisture from its surroundings. No power source is required during operation.
- Continuous Absorption: The stone continuously works to absorb humidity from the air within your enclosed storage space.
- Moisture Indicator: Monitor the indicator window on the side of the stone. When the stone is dry and actively absorbing moisture, the indicator will be white.
- Saturation Indication: As the stone absorbs moisture and becomes saturated, the indicator window will gradually change from white to blue. This signals that the stone needs to be recharged.
4. Maintenance (Recharging)
Recharge the dehumidifier stone when the indicator window turns blue (WET).
- Remove Cover: Carefully remove the protective rubber cover from the stone.
- Recharge Method: Choose one of the following methods to recharge the stone:
- Oven: Place the stone in an oven preheated to 300°F (150°C) for approximately 1 hour.
- Microwave: Place the stone in a microwave on defrost mode (200W-300W) for 9 minutes.
- Cool Down: Allow the stone to cool completely to room temperature before replacing the protective rubber cover.
- Indicator Reset: Note that it may take a few hours for the indicator window to fully return to white (DRY) after recharging.
CAUTION: The stone will be HOT after recharging. Handle with care.
CAUTION: Do not overheat the stone.
