No exposed parts, computer board wiring is correct, no naked or wrong connection, check whether the spring is connected, should be connected firmly, with or without falling off, check whether the high and low voltage switch is broken, whether the high pressure switch pressure screw is off; check into Water, flush the solenoid valve with or without the exposed part of the coil; check other accessories again, no damage is required, and a shortage occurs.
Sixth, the installation notes:
1, pay attention to service attitude, to be modest, kind and effective communication and communication with users.
2. Installers bring their own shoe covers, gloves and rags.
3, the choice of installation location on the one hand to facilitate installation, but also easy to repair and maintenance. It varies from person to person, from person to person, from actual situation, proposes our plan, and respects the user's thoughts.
4, whether it is placed in the position, or to bind the water pipe, we must pay attention to the appearance and practical.
5. If you need to wear a wall, or punch holes in countertops, cabinets, etc., pay attention to maintaining its integrity, and be reasonable and beautiful. If the situation cannot be controlled, you should first inform the user of the possible consequences and damages. Get their consent. The same is true when accessing the water tee.
6. When installing the machine, first clean the space of the machine, and the surrounding environment must not be dirty when the machine is installed.
7. Turn on the water source first, and then turn on the power when the machine is full.
8. After the installation is completed, the user should be informed of the method of use and precautions, and inform the user of the abnormal situation that may occur, and propose an emergency treatment.
9. After the installation is completed, carefully check and debug, and do a basic registration to ensure that everything is normal and leave the site.
7. Install the machine (1) Select a reasonable installation position, as close as possible to the water source, power supply and drain port, and install it in the cabinet.
(2) Installation of water inlet tee and ball valve:
1. Close and confirm that the main valve is closed (open the faucet without running water)
2, the old pipeline should be very easy to damage, to remind the user, find an experienced person or the animal husbandry department to assist.
3. Remove the faucet, install the water inlet tee and the ball valve to wrap the raw material belt, and then install the faucet.
4. Confirm that there is no water leakage after installation.
(3) Assembly machine
1. RO film, RO film direction, with two small sealing rings at one end, press the bottom by hand (can wipe a little Vaseline), can not use the cover to the top or squat. Check the seal ring for large defects. The seal on the cover must be placed on the membrane shell and coated with a small amount of Severin.
2. Install the filter element, first wrap the filter housing around the raw material strip, in order from right to left, 5 micron PP

5 After connecting, straighten out the pipe.
Eight, the pure water machine debugging (1) purpose, the last comprehensive adjustment of the machine, check to prevent errors.
(II) Method and role
1. Open the inlet ball valve and find the gooseneck faucet. After filling the water, turn on the power; 1, 2, 4, 5 lights, then 1, 2, 3, 5, the light is on, after 1 minute, 1, 3 5, the light is on, the water volume of the sewage drain pipe is changed from large to small, which proves that the flushing solenoid valve is intact and effective. The check valve is unobstructed.
2. After the standby device is normally water-making, (the water flow is stable, no air bubbles), close the ball valve on the water storage tank, close the gooseneck faucet, and later, the pure water machine stops, which proves that the shutdown function of the high-voltage switch is intact; Gradually stop, prove that the water inlet solenoid valve is intact, effective: the high pressure pump should not be operated frequently, which proves that the check valve is closed tightly.
3, open the goose faucet, the water pressure is gradually reduced, after a few seconds, the pure machine normal water production, prove that the high-voltage switch boot function is intact and effective. In the normal water production process, the pure wastewater volume flow rate is uniform, which proves that the water inlet solenoid valve is good.
4. Repeat the above work 2-3 times.
5. Close the inlet ball valve, the pure water machine stops, open the inlet ball valve. After several tens of seconds, the pure water machine is turned on, which proves that the low-pressure switch of the pure water machine is functioning properly and effectively, repeating 2-3 times.
6. After everything is normal, fill the pressure storage tank with pure water, open the goose faucet, and rinse the pure water to remove the activated carbon until the water is clean. Turn off the goose faucet to let the machine water normally.

Nine, pure water machine fault diagnosis and elimination (1) no water
1. Water and electricity are normal.
2, high pressure pump transfer, with or without waste water, if there is waste water, water inlet system, drainage system, no problem, check valve stuck, no pure water out of the faucet, whether the film is scrapped in advance, or has been used, water is not Smooth or not water; there is no blockage in other places.
3. If there is no waste water, check the water inlet solenoid valve, whether it can not be opened, the water can not pass, and check whether the filter element has been blocked, to the replacement period.
4, the pump does not turn, there is no water, always 3, 4, 5 lights, check the high voltage switch, (short circuit method).
5. The pump has no pressure (the pump is also running).
6. The circuit does not check the circuit normally.
(2) The water storage tank is full but does not stop to check the high-voltage switch. If the pressure is too high, if it is too high, adjust it to 2.8-3Kg/cm. (The water pressure gauge is selected, the range of 1/3-2/3 is the most accurate. The measurement is multiplied by 2,0.6 Ma.) The pressure is not too large, the pressure is too high, and the inlet pressure is increased accordingly, so that the wastewater will increase. The indirect reaction increases and the wastewater increases. The pressure of the indirect reaction high pressure pump is less than 3Km/cm2a, the pressure of the high pressure pump is not enough, and the pressure of the high pressure pump is too low, and the normal pressure should be 6-8Kg/cm2.
(3), no water does not start 4, 5 lights, short circuit method check high voltage switch. 3, 5 lights, open circuit check the low voltage switch.
(4) After the shutdown, the wastewater does not stop entering the water. The solenoid valve is not closed tightly, or it is reversed. The backstop valve does not stop returning water. In both cases, the waste water is different. The former tap water and the latter one is pure water. The water quality is different: the amount of water is different. The former type is relatively rushing, and the latter type of flow is small. Because the backstop valve causes non-stop waste water, the water tank barrel valve can be closed, and the waste water flow stops, which can be judged.
(5) The machine frequently starts the backstop valve to return water, and the high pressure switch pressure is too high.
(6) Judging its fault according to the action of each component.
1, high voltage switch:
The water is not stopped, and the pressure tank is short of water and does not start.
2. Check valve:
Failure 1. The wastewater does not stop and the water quality is good;
Fault 2, the high pressure pump runs without pure water;
Fault three, the check valve spool is stuck but pure water, the pure water machine is running normally, the indicator light is normal, but no water is produced.
3. Inlet water solenoid valve:
Failure 1. The wastewater is not closed, the water quality is poor, and the flow rate is large.
Fault 2, the water inlet solenoid valve can not be opened, does not enter the water, resulting in no pure water, the characteristic is that the computer board shows normal, the pump is running normally, and the wastewater is not.
4, low voltage switch:
One of the faults, no water stop after stopping the water, the computer board is 1, 3, 5 lights on, the open circuit method.
The second problem is that after water, the water pressure is normal, no power on, short circuit method.
5. Flush the solenoid valve:
One of the faults, no flushing, the solenoid valve can not be opened.
The second problem is that the shutdown is not strict and the wastewater is flowing. When the wastewater flow rate is large, the pressure will be reduced a lot, and in severe cases, no water will be produced.
6, high pressure pump:
The pressure is not enough to produce water properly. Without stopping the machine, the shutdown pressure of the high-voltage switch is not reached, and the water quality is not normal.
7, pressure bucket:
One of the failures is that there is no water or less water. First, the water is leaking, the water is out of the mouth, and it cannot be repaired.
The second fault, the yellow water, the PE liner rupture, causing the water to directly contact the steel drum, rust, surface and taste.
8, R. O film:
The removal rate is low, 90% lower, and abnormal. Over time, the increase in water consumption, removal rate, and water production gradually decrease.
9, filter:
One of the faults, blockage, the first level of blockage, the computer board only lights the fifth light, (green moss, bacteria, sediment blockage). The water is stopped, the second and third levels are blocked, the 1, 3, and 5 lights are all on, and there is no waste water to make water. The same as the water inlet solenoid valve is not opened, the segmentation method is excluded.
The second fault, the fifth level is blocked, the water is full, there is no pure water, and the segmentation method is excluded.
The third fault, the filter element fails, affecting the life and effect of various parts of the machine.
10. The computer board indicates the working status and redistributes the circuit. Four lights or more than four lights are on for a long time (more than 2 minutes), there is a problem with the computer board: 3, 4, 5 lights are on, but the water is not full, the problem of the high voltage switch is eliminated, and the computer board is faulty. 1, 3, 4, 5 lights, the computer board itself is faulty.
