Introduction
This manual provides instructions for the installation, operation, and maintenance of your Crystal Quest Fluoride Countertop Water Filter System. This system is designed to reduce or eliminate a wide spectrum of contaminants from tap water, including fluoride, chlorine, heavy metals, sediment, and inorganic compounds, providing cleaner and safer drinking water.
The system is engineered for durability and reliable performance, offering a filter life of up to 10,000 gallons or 1-3 years before a cartridge replacement is necessary, depending on water quality and usage. Its countertop design allows for quick and easy installation without complex plumbing.

Setup and Installation
The Crystal Quest Countertop Water Filter System is designed for easy, tool-free installation on most standard kitchen faucets. Follow these steps for proper setup:
- Remove Faucet Aerator: Unscrew and remove the aerator from your kitchen faucet.
- Attach Adapter: Determine the type of thread on your faucet. Select the appropriate adapter from the included set and screw it onto the faucet. Tighten manually.
- Connect Diverter Valve: Screw the diverter valve onto the faucet adapter. Ensure the gasket (pre-installed in the diverter valve) is securely positioned. Rotate the diverter valve stem to the desired position and re-tighten the swivel collar if necessary.
- Connect Hose to Filter: Use the small retaining nut to securely attach the unit hose to the filter housing.
- Position Filter: Place the water filter unit in a convenient location on your countertop, typically next to the sink. Insert the filter's spout firmly into its housing.
Note: Adapters are included to fit most faucets. For a tight seal, you may need to use the gasket from your faucet's original aerator in addition to the washers provided with the adapters. If the included adapters do not fit, consult a local plumbing or hardware supplier for assistance in obtaining a correctly threaded adapter.

Operating Instructions
To use your Crystal Quest Countertop Water Filter System:
- Activate Water Flow: Turn on your kitchen faucet.
- Engage Filter: Turn the handle on the diverter valve to direct water flow through the filter. Filtered water will dispense from the filter's spout.
- Bypass Filter: To use unfiltered tap water, turn the diverter valve handle to its original position. Water will then flow directly from your faucet.
- Stop Water Flow: To stop all water flow, turn off your kitchen faucet and then return the diverter handle to the bypass position.
It is recommended to flush the filter for a few seconds before initial use or after periods of inactivity to ensure optimal water quality.
Maintenance
Regular maintenance ensures the longevity and effectiveness of your water filter system.
Filter Cartridge Replacement
The fluoride filter cartridge should be replaced every 6-12 months, or sooner if you notice a significant reduction in water flow or a change in water taste. The system's overall filter life is rated for up to 10,000 gallons or 1-3 years, but individual cartridge life depends on incoming water quality, chemistry, pressure, and usage.

Cleaning the System
Periodically wipe down the exterior of the stainless steel housing with a soft, damp cloth to keep it clean. Avoid using abrasive cleaners or solvents.
Troubleshooting
If you encounter issues with your water filter system, refer to the following common problems and solutions:
- Reduced Water Flow: If the water flow from the filter slows significantly, it typically indicates that the filter cartridge is nearing the end of its lifespan and requires replacement.
- Unpleasant Taste or Odor: A change in water taste or the presence of an odor suggests that the filter cartridge may be exhausted and needs to be replaced. Ensure the filter was properly flushed after installation or replacement.
- Leaking Connections: Check all connections, especially at the faucet adapter and diverter valve, to ensure they are tightened securely. Verify that all gaskets and washers are correctly seated.
- No Filtered Water: Ensure the diverter valve is fully engaged to direct water through the filter. Check that the main faucet is turned on.
- Water Quality Concerns: If you suspect the filter is not performing as expected (e.g., no change in water test results), re-check the installation steps to ensure all components are correctly assembled and sealed. Consider replacing the filter cartridge if it's old.
