What should I pay attention to water purifier for daily use?

Please read the following precautions in detail before use： 

* To prevent rapid blockage of the filter cartridge, please close the three-way ball valve before every use, and let the water flow out for about 5 seconds at the unfiltered setting.

* If the water is highly coloured or turbid due to work on your water network, do not let the water run at the filtered setting until the water is clear.

* If the water purifier has not been used for more than two days, please open the three-way ball valve and let the water flow out at the filtered setting for 5 minutes.

* If you plan not to use the water purifier for more than two weeks, please seal the filter cartridge well and keep it in the fresh-keeping room. When it is used again, let the water run at the filtered setting for 10 minutes before use.
