Cabinet type water purifier installation process description

The fully automatic reverse osmosis pure water machine is a kind of facility that effectively controls the terminal tap water automatically controlled by a microcomputer, and is convenient to install and use. When you purchase or install the machine for the user, in order to ensure the installation quality, you can usually install in the following order: install RO membrane → fiber filter → precision activated carbon filter → fiber filter → punching → install the host → close the total valve → install Water three-way → Install water into the water → Inlet water directly to the fiber filter water pipe → Check whether the water inlet leaks → Install the water tank on the ball valve → Gooseneck faucet → Gooseneck faucet to the rear carbon outlet pipe → Waste water to the sink water pipe → After the activated carbon front-end water pipe → turn on the power → check the water quality → after the water quality is qualified and stabilized → connect the ball valve on the water tank → water → water → re-water → end the installation.

(1) Install RO membrane

Remove the RO film packaging film, remove the water pipe at the cover of the RO film casing, unscrew the RO membrane cover, insert one end of the two rubber sealing rings into the mouth of the RO membrane casing, and turn it to the bottom. Move the sealing ring of the membrane shell end cover to the screw end of the RO membrane shell, screw the shell cover with hand force, install the water pipe, and tighten.

Check if the elbow at the end cap is loose. If it is loose, remove it, wrap 2-3 turns of the raw tape, and then screw it on as it is.

Special attention: Wash the hands before removing the outer packaging of the RO membrane. Keep the hands clean during the installation process, and do not cause pollution to the RO membrane.

(2) Installing the filter element

Remove the plastic packaging film and insert the fiber filter, the granular activated carbon filter and the side of the fiber filter with double seals into the interface of the filter cap. Apply a little white Vaseline along the perimeter of the O-ring on the filter bottle, screw on the filter bottle and tighten by hand. When using a special wrench, the tightening process should be even and not too large.

(3) Installing a fixed host

1. Wall mounting: Two holes with a diameter of 8 mm are made at the selected mounting location. Place the plastic expansion bolt that is carried randomly, screw in the screw, hang the main unit and tighten the screw.

2. Installation in the cabinet: It can be fixed without punching, and the position can be stabilized.

Whether installing on a wall or in a cabinet, consideration should be given to the convenience of replacing the filter element and repairing it in the future. Especially when installing in the cabinet, the water machine should be placed outside the cabinet door for installation.

3. Installation of gooseneck faucet preparation: Install at the location selected by the customer. If the gooseneck faucet is to be installed on the conditioning table of the kitchen, a hole with a diameter of 12 mm should be drilled on the conditioning table. If the gooseneck faucet is installed on the wall, drill two holes with a diameter of 6~8 mm according to the hole distance of the bracket at the selected position, insert the plastic expansion bolt, and fix the bracket to the wall with self-tapping screws. Then install the gooseneck faucet in sequence.

When punching holes in marble countertops, special drill bits should be used for positioning with positioning plates. When twisting holes in marble (synthetic material), a normal twist drill should be used. Both types of punching use ordinary hand drills, and must not use impact drills.

4. Install the ball valve on the water storage bucket: wrap the sealing tape around the thread of the storage bucket for 6~8 turns, screw into the upper ball valve, and then tighten the upper ball valve with your hand. Place the bucket in the appropriate location.

5. Install the gooseneck faucet: When installing the gooseneck faucet, enlarge the soft rubber ring above, put a small soft rubber ring, hard rubber pressure plate, metal washer in the bottom, and then tighten the nut.

6. When installing the water pipe on the water purifier, a pipe plug must be placed at the end of the pipe to prevent water leakage.

(4) Connecting water pipes of water machine parts

1. The tap water pipe closes the indoor total valve. Install the water inlet tee and the water inlet straight (strap) at the water supply location selected by the user, and install the rear water parts. Seal tape should be used for these three parts to prevent water leakage.

2. The nuts on the interfaces of the water mains on the machine are marked with the name of the connecting parts. The installer should know in advance. The water pipe carried by the water purifier is 5 meters. The user should take care of the length of use of each part of the water pipe, and the end of each butt pipe should be aligned.

3. Inlet water straight through - fiber filter filter cap water pipe:

Inlet water straight through: Unscrew the inlet ball valve tightening nut, insert the water pipe into the nut, insert the water pipe into the water outlet of the water inlet (to be inserted), then tighten the nut to close the water inlet. position. Connect the other end to the upper end of the fiber filter cartridge cap (all hose ends should use a random plug, insert the tube to the end and tighten the plastic nut by hand).

Check the water supply for leaking water in all parts of the pure water machine (open the main valve, open the rear water switch, release the sewage, close the water switch after the water is clear, open the water into the water for inspection.

4. Gooseneck faucet - rear activated carbon outlet pipe:

Gooseneck faucet: The interface should be fixed with a special special tightening nut: insert the water pipe into the nut, insert the water pipe into the sealing plastic apron and expose the water pipe to 1-2 cm, insert the water pipe into the lower part of the gooseneck faucet, then rotate Tightly tighten the nut (use a wrench to tighten it).

5. Post-activated carbon outlet: Installed according to the general water pipe connection.

6. Waste water ratio - lower sink water pipe:

The wastewater is installed at a specific water pipe connection. The other end can be connected to the user's sewer (concentrated water can also be connected to other containers for general washing water).

7. Rear activated carbon front end tee - ball valve on the water tank:

Installed here as a general water pipe connection. Usually, the water pipe at the ball valve on the water tank can be temporarily disconnected, and then connected after the water quality inspection is completed.

As a device for making ultrapure water, EDI can be used as a secondary desalination device after reverse osmosis equipment to produce up to 10-18.2 MΩ.CM. EDI equipment can run continuously without the need for chemical regeneration. In a specific application, only adjusting the operating current of the EDI can change the effluent quality. Therefore, it is widely used in the microelectronics industry, semiconductor industry, power generation industry, pharmaceutical industry and laboratories. It can also be used as pharmaceutical distilled water, food and beverage production water, boiler feed water for power plants, and other applications of ultrapure water.

Continuous deionization (EDI, Electrodeionization or CDI, continuous electrodeionization) is the adsorption of anion and cations in water by a mixed ion exchange resin, and these adsorbed ions are respectively transmitted through the anion-cation exchange membrane under the action of a direct current voltage. The process of removal. This process ion exchange resin is electrically continuously regenerated and therefore does not require regeneration with acids and bases. This new technology can replace traditional ion exchange devices to produce ultrapure water up to 18M-CM. It can be described relatively clearly: EDI uses the form of cation and cation membranes, and adopts symmetric stacking. The anode and the cation resin are sandwiched between the anion and cation membranes, and the cation and cation exchange are carried out under the action of DC voltage. At the same time, under the action of the voltage gradient, water will be electrolyzed to produce a large amount of H+ and OH-, and these H+ and OH- are continuously regenerated in the middle of the ion membrane. Since EDI is continuously exchanged-regenerating, the purity of pure water is getting higher and higher, so that high-purity ultrapure water is easily produced.

EDI technology is a new membrane separation technology formed by the organic combination of electroosmosis and ion exchange. The ion exchange effect of the ion exchange resin and the selective permeation of the anion and cation exchange membranes on the anion and the cation can realize the directed migration of the ions under the action of the direct current electric field, thereby completing the deep demineralization of the water.
