Setup Instructions
Follow these steps to set up your new Culligan with ZeroWater Technology 12-Cup Water Filter Pitcher:
- Unpack Components: Carefully remove all components from the packaging. You should have the pitcher, the 5-stage filter, and the TDS meter.
- Wash Pitcher: Wash the pitcher and lid with mild soap and warm water. Rinse thoroughly. The pitcher is BPA-free.
- Prepare Filter: Remove the filter from its protective packaging. No pre-soaking is required.
- Install Filter: Screw the 5-stage filter firmly into the threaded opening on the underside of the water reservoir (the upper part of the pitcher). Ensure it is securely tightened to prevent unfiltered water from bypassing the filter.
- Assemble Pitcher: Place the reservoir with the installed filter into the pitcher body. Place the lid on top of the reservoir.
- Initial Fill: Fill the reservoir with cold tap water. Allow the water to filter through completely into the main pitcher body. Discard the first two full pitchers of filtered water to prime the filter and remove any carbon dust.
- Test with TDS Meter: Use the included TDS meter to test the filtered water. The meter should read "000" indicating virtually all dissolved solids have been removed. If it does not read "000", ensure the filter is properly installed and repeat the initial fill and discard steps.

Operating Instructions
Using your Culligan with ZeroWater Technology pitcher is straightforward:
- Filling the Pitcher: Lift the easy-slide lid and pour cold tap water into the top reservoir. The water will slowly filter through the 5-stage filter into the main pitcher. Do not overfill the reservoir.
- Pouring Water: Once the water has filtered, you can pour it directly from the pitcher. The ergonomic handle and smooth spout are designed for easy, no-drip pouring.
- Monitoring Water Quality: Regularly use the built-in TDS meter to check the quality of your filtered water. A reading of "000" indicates optimal filtration.

Maintenance
Proper maintenance ensures the longevity and effectiveness of your water filter pitcher:
- Filter Replacement: The TDS meter is your indicator for filter replacement. When the meter reads "006" or higher, it's time to replace the filter to maintain optimal water quality. Filter life can vary based on your tap water's initial TDS level and usage.
- Replacing the Filter: Unscrew the old filter from the reservoir. Dispose of the used filter. Screw in a new Culligan with ZeroWater Technology filter firmly. Remember, this pitcher is compatible only with NEW Culligan with ZeroWater Technology filters and not with legacy ZeroWater filters.
- Cleaning the Pitcher: Wash the pitcher and lid regularly with mild soap and warm water. Do not wash the filter with soap or put it in a dishwasher.

Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| TDS meter reads above "000". | Filter is exhausted or not properly installed. | Ensure filter is screwed in tightly. If still high, replace the filter. |
| Water tastes unusual or has an odor. | Filter is exhausted or not properly primed. | Replace the filter. Ensure the first two pitchers of filtered water were discarded during initial setup. |
| Water filters very slowly. | Filter is nearing the end of its life or tap water has high dissolved solids. | This is normal as the filter absorbs more contaminants. Replace the filter if the TDS reading is high. |
