1. Routine maintenance
- Organic solvent such as gasoline 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 puri�ed water 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 (≥7 days), 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 puri�ed water to empty the system, and
turn off the power. Before using it again, turn on the puri�ed water for at least 10

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 low rate is observed, we recommend changing the �lters as well.
This system can only work with Philips �lters.

* 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.
