The water purifier generally adopts five levels of filtration. After the use of time, impurities and organic matter are attached to the filter core, resulting in water quality degradation and even harm to the safety of drinking water. Therefore, the filter element should be replaced regularly.

The life of the filter element is as shown in the figure below:

Replace the filter element

(only when the filter element is replaced, can you drink healthy water)

It should be noted that, due to the different process and structure, the life of the filter cartridge is different, which is summarized as follows:

Note: different areas have different water quality, water consumption and climate.

How to change the filter element of water purifier? -- the method is as follows:

1. Replace the filter element of the front filter.

The filter element is placed in the back of the water meter to remove large particles from tap water, such as gravel. The replacement cycle is: about 3 months.

For specific steps, please refer to the article "how to change the front filter element".

Replace the filter element of water purifier.

1. Close the water inlet ball valve on the three-way, and open the residual water in the faucet;

2. Hold the main filter core in a horizontal rotation (inward) 90 degrees or so, and remove the filter core.

3. Open the new filter cartridge, remove the filter cap, vertically align the head upward, and rotate (outward) about 90 degrees, and gently shake the main core to ensure that it is in order to prevent leakage;

4. Open the inlet ball valve and the water tap is not closed, the water after a few seconds, letting it since the row 10 minutes, one is active filter to ensure filtering and prolong service life, the second is there may be a small amount of activated carbon powder out of leading to deep color water flows to its clear;

5. Observe whether the main core is leaking, turn off the water tap after 10 minutes, and install it.

In replacing pre tertiary filter, turn off the first electroplating ball valve and ball valve, pressure barrels open gooseneck faucet, to row residual water in the pipe, when the water no longer flow, will be equipped with a filter shell wrench cartridge filter shell open, take out the old filter, loaded with the specifications of the new filter, the filter shell at the top of the black "O" type circle, coated with lubricant like vaseline, then the "O" type circle into the filter shell in the slots, in vertical way, tighten the filter shell, as far as possible to avoid "O" type circle shift, then open the electroplating ball valve and ball valve pressure barrels.

Three, replace RO reverse osmosis membrane.

Shut off ball valve electroplating, wait ten minutes, unscrew the nut on the membrane shells the right joint pull water out, and then close the pressure barrels of ball valve, unscrew the top of the nut joint, and tap into an empty barrel or sink in, with his left hand held tight reverse osmosis membrane tube, then use tongs to live old reverse osmosis membrane, it pulled up outside the membrane shells. Insert the newly opened reverse osmosis membrane into the reverse osmosis membrane tube until the end of the two black "O" ring ends at the bottom end of the film shell and then screw the membrane cover tightly. Plug in the pipe and tighten the joint nut. Then open the electroplating ball valve and let the machine run for more than two hours. After the system enters the normal water production state, connect the water pipe to the pressure bucket ball valve and open the pressure barrel ball valve.

Notes:

1. Check the length of the filter cartridge: compare the length of the old and new filter cores. If the length of the new filter is insufficient, the rubber mat can be used to solve the problem. Rubber pad can be removed from the old filter center (rubber pad can be removed from the old filter center)

2, household reverse osmosis pure water machine placed on filter put filter is, especially the PP is easy to put the partial twist filter bottle by hand when you need to feel, screw fixed easily put a partial, twist filter bottle by hand when you need to feel. Small T33 is marked with flow direction. It is marked with the direction of flow.

3 installed flush filter, pure water machine parts before they can access level system, after washing when disconnected the next level of pipeline, ultrafiltration water purification machine, filter installed only after flush before they can access level of the system, the disconnected when cleaning the next level of pipeline, need to open the inlet ball valve can wash, need to open the inlet ball valve can wash and rinse time 5 minutes, rinse after the access to the lower processing system. Minutes, after washing, access to the lower processing system.

4. The filtering time depends on the water quality, generally 6-8 months, and PP can be cleaned and used. No more than one year.
