Water purifier filter replacement method

1, pre-filter filter replacement

When replacing the pre-filter element, first close the water inlet three-way ball valve, remove the two hoses at the two ends of the front transparent bottle, and control the water in the front transparent bottle to dry, and then put the pre-filter out. The white quick connector at the outlet (marked with “OUT”) is unscrewed, and the front transparent bottle is unscrewed to remove the old filter element, and the inside of the filter bottle and the filter bottle cover are cleaned, and a new filter element of the same specification is installed, and the black cover is rotated Upper (to avoid the "O" rubber ring shift), and then use a loose spanner to fasten the white quick connector, and finally the white hose into the front filter inlet (with "IN" mark) and the outlet (with "OUT" mark), so that the filter replacement of the pre-filter is completed

2, Water purifier filter replacement

Water purifier filter replacement steps are as follows:

1 Close the inlet ball valve on the three-way, open the net faucet to drain the remaining water;

2 Grip the main filter element horizontally (inward) by 90 degrees and remove the filter element downwards.

3 Open the new filter cartridge, remove the filter cover, insert the vertical alignment head, and rotate it laterally (outwardly) by about 90 degrees. Gently rock the main core to ensure safety, to prevent water leakage.

4 Open the water inlet ball valve. At this time, the net tap is not closed. After a few seconds, the water is discharged and allowed to self-arrange for 10 minutes. The first is to activate the filter to ensure the filtration function and to prolong the service life. Second, there may be a small amount of active carbon powder rushing out to cause deep color. Water should be drained;

5 Observe whether the main core leaks water. After 10 minutes, close the clean tap and complete the installation.

3, before the water machine three filter replacement

When replacing the front three-stage filter element, first turn off the plating ball valve and the pressure barrel ball valve to open the gooseneck faucet to drain the remaining water in the pipeline. After the water no longer flows out, use the filter shell wrench to install the filter element with the filter element. Open, remove the old filter element, and insert the new filter element of the same specification. Place the black “O” ring above the filter housing with a lubricant such as Vaseline and place the “O” ring into the groove in the filter housing. Inside, in a vertical manner, the filter housing is tightened to avoid shifting the “O” ring, and finally the plated ball valve and the pressure tank ball valve are opened.

4, pure water machine RO reverse osmosis membrane replacement

When the RO reverse osmosis membrane is better, first close the plating ball valve. After waiting ten minutes, unscrew the nut connector on the right side of the membrane shell, pull out the water pipe, close the pressure barrel ball valve, and unscrew the nut above it. Joint, and the water pipe into an empty bucket or sink, with the left hand tight reverse osmosis membrane tube, and then clamp the old reverse osmosis membrane, pull it out of the membrane shell. Insert the newly opened reverse osmosis membrane into the reverse osmosis membrane tube until one end of the two black small O-rings abut on the bottom of the membrane shell and tighten the membrane shell lid tightly. Insert the water pipe and tighten the connector nut. Afterwards, the plated ball valve was opened again, allowing the machine to run for more than two hours. After the system was brought into a normal state of production, the water pipe was connected to the pressure tank ball valve and the pressure tank ball valve was opened.
