Setup
1. Unpacking and Initial Cleaning
Carefully remove all components from the packaging. Wash the dispenser, reservoir, and lid with mild soap and warm water. Rinse thoroughly before first use. Do not wash the filter cartridge with soap.

2. Filter Installation
- Remove the new filter from its protective packaging.
- Rinse the outside shell of the new filter under cool tap water for 30 seconds.
- Insert the filter into the designated opening in the reservoir. Twist clockwise to secure it into position.
- Ensure the filter is firmly seated to prevent unfiltered water from bypassing the system.

Operating Instructions
1. Filling the Dispenser
To fill the dispenser, slide open the circular lid on top of the reservoir. Pour cool or room temperature tap water into the reservoir. The water will slowly filter through the 5-stage filter into the lower chamber.

2. Dispensing Water
Once the water has filtered into the lower chamber, it is ready for consumption. Use the thoughtfully crafted spigot for ergonomic pouring. Simply pull the lever forward to dispense water.

3. Using the Built-in TDS Meter
The dispenser features a built-in Total Dissolved Solids (TDS) meter. This meter measures the level of dissolved solids in your water instantly. When the meter reads "0 PPM", it indicates that your filter is effectively removing virtually all TDS from your water. The meter will alert you when it's time to change your filter (typically when it reads 6 PPM or above).

Maintenance
1. Filter Replacement
Replace the filter when the built-in TDS meter reads 6 PPM or above, or when you notice a change in water taste. Refer to the "Filter Installation" steps in the Setup section for detailed instructions on replacing the filter. Use only new Culligan with ZeroWater Technology filters. This dispenser is not compatible with legacy ZeroWater filters.

2. Cleaning the Dispenser
Regularly clean the dispenser, reservoir, and lid with mild soap and warm water. Rinse all parts thoroughly. Avoid using abrasive cleaners or scrubbers that could scratch the acrylic material. The filter cartridge should not be washed with soap.
Troubleshooting
- Slow Filtration: If water filters slowly, ensure the filter is correctly installed and not clogged. If the filter is old, it may be time for a replacement.
- High TDS Reading (above 0 PPM): If the TDS meter consistently reads above 0 PPM shortly after a filter change, ensure the filter is properly seated and twisted into place. If the issue persists, the filter may be exhausted or defective and requires replacement.
- Unusual Taste/Odor: A change in water taste or odor typically indicates that the filter needs to be replaced.
- Leaking: Check that all parts are correctly assembled and tightened. Ensure the spigot is fully closed after dispensing.
