1. How to replace the front filter of the three-stage ultrapure water machine
There will usually be water spillage during this process, please prepare a basin or rag to clean the utensils:
a) Close the electroplating ball valve and pressure ball valve cylinder;
b) Open the gooseneck tap to drain residual water in the pipes;
c) After the water no longer flows through, open the filter housing of the filter element with a wrench equipped with a filter housing;
d) Remove the old filter with new filter element specifications;
e) Put on the top of the black and other filter housing; O" rings, coated with lubricant such as petroleum jelly, then other O" into the filter housing in the slot.
f) Tighten the housing in a vertical fashion, avoiding as much as possible; displacement of the O" ring.
g) Open the electroplated ball valve and the pressure barrel of the ball valve. Household pure water machine, pure water machine, reverse osmosis membrane
2. Steps and precautions for replacing the reverse osmosis membrane
There will usually be water spillage during this process, please prepare a basin or rag to clean the utensils:
When buying a new water purifier, the reverse osmosis membrane is usually in the reverse osmosis membrane tube. After a period of use, when the reverse osmosis membrane needs to be replaced, you can ask for professional services, or replace it according to the following steps:
Preparation of instruments: wrench, pliers, bucket, scissors or knife.
Note: During installation/replacement, try to avoid pulling other pipes to avoid leakage.
3. Change steps
1. Close the electroplating ball valve and wait for ten minutes. (Let the system pressurize)
2. Loosen the nut on the joint on the right side of the membrane shell by hand or tools, and pull out the tube.
3. Facing the machine, hold the membrane shell tightly with your left hand, and screw the end cover into your hand. (If the rear RO membrane tubing on top of the charcoal filter is interfering with the operation of this step, it may be shifted a bit or pulled all the way, and if it is pulled all the way, you are opening extra tubing.)
4. Close the ball valve, loosen the top of the nut joint by hand or the pressure barrel of a tool, and insert it into an empty bucket or sink.
5. Hold the reverse osmosis membrane tube tightly with your left hand, then clamp the old reverse osmosis membrane with pliers, and pull it up out of the membrane shell.
6. Open the envelope of the new reverse osmosis membrane and take it out.
7. Put the new reverse osmosis membrane into the unsealed reverse osmosis membrane tube until there are two small black & etc.; one end of the O" ring to the bottom of the membrane shell.
8. Turn the membrane shell in the same posture, cover the membrane shell tightly and tighten it.
9. If necessary, adjust the direction in a clockwise (locked) direction, pointing the contact toward the rear of the machine.
10. Insert the pipe and tighten the connecting nut. (don't forget the pipe plug)
11. Open the electroplating ball valve.
12. After more than two hours, let the machine run. After the water system enters a normal state, connect the pipe and the ball valve of the pressure tank and open the pressure tank.
