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

    Published on 2019-08-28
    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.

    The information on this page applies to the following models: WP4111/90 , WP4141/90 , WP4161/90 .
