3. Setup Instructions
- Unpack and Wash: Carefully unpack all components. Wash the dispenser reservoir, lid, and filter compartments with mild, scent-free soap and warm water. Rinse thoroughly to remove any soap residue.
- Prepare Filters: Remove the new filters from their packaging. Submerge each filter in water for approximately 10-30 minutes to prime them. This helps remove air bubbles and ensures optimal filtration from the first use.
- Install Filters: Insert the prepared filters into their designated compartments within the dispenser. Ensure they are seated firmly.
- Initial Fill: Place the lid on the dispenser. Fill the top reservoir with tap water. For best results, pour water into the reservoir, avoiding direct contact with the filters. Allow the water to filter through completely. Discard the first two full reservoirs of filtered water to flush out any carbon dust and prepare the filters for regular use.
- Positioning: Place the dispenser on a flat, stable surface, such as a countertop or refrigerator shelf. The compact design (8.5"L x 12.4"W x 8.7"H) allows it to fit nicely in most refrigerators.

4. Operating Instructions
- Filling the Dispenser: To refill, slide open the lid and pour tap water into the top reservoir. The dual-filter system provides an 8x faster flow rate, filtering a full reservoir in approximately 2.5 minutes.
- Dispensing Water: Position your glass or bottle under the easy-pour spigot and push the lever to dispense filtered water. The spigot is designed to be leak-proof.
- Monitoring Filter Life: The lid features a smart filter life indicator. Observe the indicator to determine when filter replacement is needed (Good, Replace Soon, Replace Now).
- Capacity: The dispenser holds a total of 40 cups of water, with approximately 19 cups in the top reservoir awaiting filtration and 21 cups in the bottom filtered water tank.

5. Maintenance
- Regular Cleaning: It is recommended to clean the entire dispenser system weekly with mild, scent-free soap and warm water. Ensure all parts are thoroughly rinsed and dried before reassembly.
- Filter Maintenance: When refilling the top reservoir, you may remove the filters, gently shake them, and rinse them under running water to maintain optimal performance.
- Filter Replacement: The filters have a lifespan of approximately 200 gallons or 2 months, whichever comes first. Replace filters as indicated by the smart filter life indicator or after the recommended period to ensure continued effective filtration.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow filtration or no water flow. |
|
|
| Water splashing from the lid when moving the dispenser. | Lid does not have a tight seal. | Exercise caution when moving the dispenser, especially when full. Avoid sudden movements. Consider moving it when the top reservoir is empty. |
| Water still has a high TDS (Total Dissolved Solids) reading. | This system is designed to add alkaline substances and reduce specific contaminants, not to lower TDS. | This is normal operation. If a low TDS value is desired, consider a Waterdrop 0 TDS Dispenser (e.g., models WD-WFD-01L, WD-WFD-01W). |

Image 6.1: TDS Explanation. This image clarifies that the system does not lower TDS, as it retains beneficial minerals, and provides examples of typical TDS levels in various beverages.
