The most important and core of the water purifier is the filter element. The quality and normal operation of the filter element directly determine whether the water quality meets the standard. Therefore, when it is used to a certain extent, it also needs to be replaced. Do you know how to replace the filter element of the water purifier? Next, I will introduce you how to replace the filter element of the water purifier and the maintenance method of the water purifier.
How to replace the filter element of water purifier
1. Replace the filter element of the prefilter. With the inlet ball valve closed, the hoses at both ends of the transparent bottle removed and the water in the transparent bottle dried, unscrew the white quick connector at the filter outlet, replace the old filter element with a new filter element, and then clean it, cover it, screw in the white quick connector, and plug in the hose at the end.
2. Replace the filter element of the water purifier. After closing the ball valve to remove the water, turn the old filter element 90 degrees or so to take it out, insert the new filter element, turn it 90 degrees or so to tighten it, and finally check the filter element for water leakage.
3. Replace the filter element of the pure water machine, close the ball valve to remove the residual water, replace the old filter element in the filter housing with a new one, put the "O" ring coated with Vaseline in the groove of the filter housing, and then tighten the filter housing.
Maintenance method of water purifier
1. When installing the water purifier, be sure to avoid being close to the high-temperature heat source, such as gas stove, water heater, etc. This is mainly because if the water purifier is baked at high temperature for a long time, the plastic part in the product will be easily melted or burnt, which will directly affect the service life of the product.
2. When installing the water purifier, it is not only necessary to avoid high temperature heat source, but also to avoid direct sunlight, because no matter which kind of water purifier is exposed to a certain amount of sunlight, blue-green algae will grow, and this substance is harmful to human body. However, in case the installation site cannot avoid direct sunlight, we should also try to put a sunshade near the water purifier or cover it with other dark cloth bags.
3. If the water purifier has not been used for several days, it needs to be flushed for several minutes when it is used again until the original water in the domestic water purifier is drained.
4. The failure of the water purifier can not be avoided. At that time, the tap water inlet valve must be closed immediately to cut off the water inlet of the water purifier, instead of blindly disassembling it.
5. After the water purifier is used, it is necessary to keep the ultrafiltration membrane core in a wet state all the time. The salesperson of the water purifier said that the drying of the ultrafiltration membrane core will lead to a significant decline in water production, and it is almost impossible to recover.
