Always ensure the switch is fully engaged in the desired position to prevent leaks or improper water flow.

The frequency of cleaning depends on your water quality and usage. Clean the cartridge when you notice a reduction in water flow or visible discoloration on the cartridge surface.
6. Troubleshooting
If you encounter issues with your Hi Tech H5 Water Purifier Filter, consider the following common solutions:
- Reduced Water Flow: This is often an indication that the ceramic cartridge needs cleaning. Refer to Section 5.1 for cleaning instructions.
- Leaks at Faucet Connection: Ensure the faucet joint and filter unit are securely tightened. Check if the correct adapter was used for your faucet. Replace any worn-out rubber gaskets if present.
- Water Not Purified: Verify that the switch/lever is fully engaged in the 'filtered water' position.
- Unpleasant Taste/Odor Persists: If the cartridge has been cleaned and the issue persists, the cartridge may need replacement, or the source water quality is beyond the filter's capacity.
If problems persist after attempting these steps, please contact your retailer or the manufacturer for further assistance.
