4. Setup and Installation
The Tier1 RWF1100 filter is designed for quick and easy, tool-free installation. Refer to your refrigerator's specific manual for exact filter location and removal instructions, as these can vary by model. Generally, the process involves removing the old filter and inserting the new one until it locks into place.

General Installation Steps:
- Locate your refrigerator's water filter compartment. This is typically inside the refrigerator, in the grille at the bottom, or in the top right corner.
- Twist the old filter counter-clockwise to unlock and remove it. Some water may drip out, so have a towel ready.
- Remove the protective cap from the new Tier1 RWF1100 filter.
- Insert the new filter into the housing and twist clockwise until it is securely locked. You may feel a slight resistance as the O-rings engage.
- Run water through the dispenser for approximately 3-5 minutes (about 2-3 gallons) to flush out any air and loose carbon particles. This ensures optimal filtration and clear water.
- Check for leaks around the filter housing.
- Reset your refrigerator's 'change filter' indicator, if applicable. Refer to your refrigerator manual for specific instructions on resetting the indicator.
5. Operation
The Tier1 RWF1100 filter operates by passing water through an activated coconut carbon block. This filtration medium is highly effective at adsorbing various impurities from your tap water.

Filtration Process:
- Chlorine Reduction: The activated carbon effectively captures chlorine, significantly improving the taste and odor of your water.
- Sediment Removal: The filter's fine pores trap rust, sand, silt, and other particulate matter, preventing them from entering your drinking water and ice.
- Turbidity Reduction: By removing suspended solids, the filter reduces turbidity, resulting in clearer water and ice.

6. Maintenance
Regular replacement of your water filter is crucial for maintaining optimal water quality and refrigerator performance. The Tier1 RWF1100 filter has a recommended service life.
Image 6.1: The Tier1 RWF1100 filter lasts up to 6 months or 300 gallons, whichever comes first.
Filter Replacement Schedule:
- Replace the filter every 6 months or after filtering 300 gallons of water, whichever comes first.
- Use the included date sticker to mark the installation date on the filter or a visible location on your refrigerator.
- If water flow significantly decreases before the recommended replacement interval, it may indicate high sediment levels in your water, and the filter should be replaced sooner.
7. Troubleshooting
If you encounter issues after installing your new filter, consider the following common troubleshooting steps:
- Reduced Water Flow: Ensure the filter is fully seated and twisted into place. Flush the filter for a longer period (5-10 minutes) to remove trapped air. If the issue persists, the filter may be clogged due to high sediment, requiring replacement.
- Leaking: Remove and re-install the filter, ensuring it is properly aligned and twisted until snug. Check that the O-rings are not damaged or dislodged.
- Cloudy Water or Air Bubbles: This is common immediately after installation and usually resolves after flushing 2-3 gallons of water through the dispenser. The cloudiness is typically air trapped in the system.
- Unusual Taste/Odor: Ensure the filter has been adequately flushed. If a taste or odor persists, verify the filter is the correct model for your refrigerator and that it is installed correctly.
If these steps do not resolve the issue, please contact Tier1 customer support.
