5. Maintenance
Emptying the Water Tank:
- When the water tank is full, the unit will automatically shut off, and the red indicator light will illuminate.
- Carefully slide out the water tank from the front of the unit.
- Empty the collected water.
- Slide the empty tank back into the unit until it clicks into place. The unit will resume operation if powered on.
Cleaning the Water Tank:
- Regularly clean the water tank to prevent mold and mildew growth.
- Use mild soap and warm water to clean the tank. Rinse thoroughly.
- Ensure the tank is completely dry before reinserting it into the unit.
Recharging Reusable Dehumidifier Boxes:
- The reusable boxes contain desiccant particles that change color from orange (dry) to dark green (saturated/wet).
- When the particles turn dark green, remove the box from its location (e.g., wardrobe).
- Place the saturated box on top of the main dehumidifier unit in the designated slot.
- Press the DRY button on the dehumidifier. The unit will enter a drying mode for the reusable box, typically for 3 hours (or longer in winter).
- Once the particles turn back to orange, the box is recharged and ready for reuse. Remove the box from the dehumidifier after drying to maintain optimal performance of the main unit.
- Note: A small amount of white powder in the box is normal and does not affect use. These boxes are only suitable for the CS12 model.
