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

1. If you are not going to use the system for more than one week, turn off the RO faucet, shut off the coldwater valve, and disconnect the power. Seal the filters and store them in the refrigerator (not the freezer). Before using the appliance again, you need to open the RO faucet and allow it to run for 10 minutes first. Otherwise, the filters need to be changed, as bacteria may grow when the system is not used for such a long time.
2. Please replace the filter regularly according to the filter life indicator.

NOTE: Actual performance may vary depending on the water quality and usage. In case of blockage or failure of the filters, it's recommended to replace the filters according to actual situations.

3. Clean the system with clear water. Do not spray the water directly. Do not use abrasive cleaner orcorrosive liquid to clean.
4. Keep the waste water pipe unobstructed to avoid damage to the filter or internal parts.
5. When the drainpipe is blocked, do not use the system to avoid waste water from soaking the floor, andturn off the system power.
6. Check the system and water pipe fittings regularly to avoid any property damage.
7. Regularly check whether the power supply and wires are damaged or loose to avoid major accidentscaused by electric leakage.
