The installation sequence of filters shall not be reversed to avoid affecting the normal function of the system.

1. If you do not use the system for a long time (more than 1 week), it is recommended to turn on the faucet to flush for a while before using it again.
2. If the system is not used for a long time, please disconnect the water supply and remove the batteries.
3. Please replace the filter regularly according to the filter life indicator.

NOTE: While the testing was performed under standard laboratory conditions, actual performance may vary depending on the source water quality and water usage. In case of premature blockage and failure of the filters, it is recommended to replace the filter in accordance with actual usage.

4. Clean the system with clear water. Do not spray the water directly onto the filter. Do not use steel wool, an abrasive cleaner,or a corrosive liquid such as gasoline or acetone.
5. When cleaning, do not pour other liquids into the filter or you risk damaging the filter system.
6. Check the system and water pipe fittings regularly for water leakage to avoid any property damages.

If using well water as the source, please make sure the feed water has been through a pre-filtration system, otherwise, large particles in well water will clog the filter easily and shorten filter life.
