Setup and Installation
The Panasonic TK-CS500-WEX is designed for countertop installation and operates using water pressure. Follow these steps for proper setup:
- Unpack the Unit: Carefully remove all components from the packaging. Ensure all parts, including the main unit, filter cartridge, and connection accessories, are present.
- Position the Purifier: Place the main purifier unit on a stable, flat countertop surface near your kitchen sink.
- Connect to Faucet: Attach the provided diverter valve to your kitchen faucet. Ensure a secure, leak-free connection. The purifier connects to this diverter valve via a hose.
- Install Filter Cartridge: Open the top cover of the purifier and insert the filter cartridge into its designated slot. Ensure it is seated correctly. Refer to the "Maintenance" section for detailed filter installation instructions.
- Flush the System: Before first use, run water through the purifier for several minutes to flush out any carbon dust or air from the new filter.

Operation
Operating your Panasonic water purifier is straightforward. The unit allows you to select between purified and unpurified water flow.
- Water Selection: Use the selector switch on the diverter valve, typically located at the faucet connection, to choose between purified water (flowing through the purifier) and unpurified tap water (bypassing the purifier).
- Dispensing Purified Water: Once the selector is set to purified water, turn on your faucet. Water will flow through the purifier and dispense from the purifier's spout.
- Adjusting Spout: The purifier's spout can swivel 180 degrees for convenience, allowing you to position it as needed for filling various containers.

Maintenance
Regular maintenance, particularly filter replacement, is crucial for ensuring the continued performance and water quality of your purifier.
Filter Cartridge Replacement
The filter cartridge has a substantial capacity of 12,000 liters, equivalent to many 1-liter bottles of water. The unit is equipped with an LED indicator to help you monitor the cartridge's remaining life.

- Monitoring Cartridge Life: Observe the LED indicator lights on the top of the unit. These lights will gradually turn off as the filter approaches the end of its life. Replace the cartridge when all indicator lights are off or when water flow significantly decreases.

- Turn off the water supply to the purifier.
- Open the top cover of the purifier.
- Carefully remove the old filter cartridge by pulling it upwards.
