VI. Maintenance
1. Routine maintenance
- Organic solvent such as gasoline etc. shall not be used for wiping the housing of the
device. If cleaning is required, please gently wipe the surface of the product with a wet
cloth after it is disconnected from the power supply.
- If the system is not used for more than 2 days, turn on the faucet and allow the water to
run for at least 5 minutes to �ush the �lters and the system.
- If the system will not be used for an extended period, take out the �lter cartridges,
seal them with plastic wraps, and store them in the refrigerator (not in the freezer).
Turn off the three-way ball valve, turn on the faucet to empty the system, and turn off the
power. Before using it again, allow the water to run for at least 10 minutes to �ush the
�lters and the system.
2. Filter lifetime
Note
For the best performance, please change your �lter cartridge according to the �lter lifetime
indicator, or the �lter replacement cycle suggested below. When a signi�cantly lower �ow
rate is observed, we recommend changing the �lters as well.

* The actual lifetime of the �lter cartridge depends on the local tap water quality and daily
usage. The recommended replacement cycle is an average based on different local tap
water quality. If the local tap water quality is below the average, the actual lifetime of
the cartridge would differ from the recommended replacement cycle. If the �lter cartridge
is blocked, please replace it.
3. Filter cartridge replacement
a. Turn off the power and water supply before replacing the �lter cartridges.
b. Remove the front cover.
c. Turn the �lter that needs to be replaced anticlockwise and pull it out.
d. Remove the packaging of the new �lter and insert the cartridge in the system.
Turn it clockwise to align the triangle icon on the �lter cartridge with the lock icon on
the system.
