1. Check the length of the filter element: compare the length of the old and new filter elements. If the length of the new filter element is insufficient, it can be solved by increasing the rubber pad. (The rubber pad can be removed from the old filter.)
2. When placing the filter element, pay attention to putting the filter element right. PP is easy to put off. When opening the filter bottle, you should feel by hand. Granular activated carbon with rubber pad end up, small T33 marked with flow direction.
3. The filter element can only be connected to the system of the lower level after it is installed and flushed. Disconnect the pipeline of the next level when flushing, and the RO level can only be flushed when it is powered up.
4. the use time of filter element depends on water quality, generally 6-8 months. No more than a year.
