2. Filling the Water Tank
The unit features dual water tanks for convenient refilling. You can add water from the top or by pulling out the bottom tank. Ensure the unit is unplugged before filling.
- Top Fill: Open the top cover and pour clean water directly into the reservoir.
- Bottom Tank: Gently pull out the bottom water tank. Fill it with clean water, then slide it back into the unit until securely in place. The bottom tank has a visible water level indicator.
Do not exceed the maximum fill line. The 1-gallon capacity water tank provides up to 8 hours of continuous cooling.

3. Using Ice Packs
For enhanced cooling, use the provided ice packs. These pre-filled polymer solidified gel ice packs should be frozen for at least 3 hours before use. Place the frozen ice packs into the water tank along with the water. This can reduce ambient temperatures by 41-49°F.
