5. Water Purifier Main Parts Function Introduction

Using the current most advanced international RO technology, standard configuration is as follows:

① First is a 10-inch 5-micron PP filter:

The aperture of the PP filter is 5 microns, can effectively filter rust, sand, other larger particles and solid impurities in water.

② Second is a 10-inch 85C granular activated carbon filter:

This machine can effectively adsorb chlorine, humus, disinfection by-products, odors, colors, and other materials.

③ Third is a 10-inch 1-micron PP filter:

This machine can further remove small particles in the water, suspended solids, colloids, etc.

④ Fourth stage is RO membrane:

Aperture is .0001 micron (0.1 nm), reduces bacterium by 4,000 fold, reduces viruses by over 200 fold, so you can effectively remove bacteria, viruses, heavy metals, pesticide residues, and other harmful substances from the water.

⑤ The fifth-stage is a post-activated carbon filter:

Regulates water taste, keeps water fresh.

Note: This machine also has an optional configuration:

Pretreatment Filter: KDF two stage filter, KDF three stage filter, sintered activated carbon filter

Post-filter: Alkaline filter, infrared mineralization activated carbon filter etc.

6. Water Purifier Accessory Functions

Storage Tank:

High Pressure Pump:

Low Pressure Switch:

Used to store water filtered by the water purifier.

Boosts pressure to create a stable environment for the RO membrane.

To prevent pump idling. When the inlet water pressure is less than 0.03 MPa or when the inlet water stops, the low pressure switch automatically shuts off the power source so the machine stops.

High Pressure Switch: Prevents pump from fully turning. When the pressure tank is full or has reached the set pressure, power supply is automatically cut off to stop the machine.

Inlet Water Solenoid Valve: Connects or cuts off incoming water. Operating pressure range is less than

≤0.6MPa.

Non-return Valve: Controls the flow direction.

Combination Flush Solenoid Valve: (1) Automatically flushes the reverse osmosis membrane.

(2)Controls waste water flow.

Transformer: Converting

AC 220V to DC 24V (the machine‟s safe operating voltage).

7. Water purifier features:

Large Flow Rate: It adopts the components of 75GPD RO membrane, the flow rate of which is 50% larger than the average, so the time of water producing is shortened and the amount of waste water is reduced by 25%.

④ Waste water pipe installation

Using a φ6mm drill to punch a small hole then take out a 6mm water pipe with proper length, one end of which is put into the hole. (See Diagram 8)

Smear some silica gel on the joint of the 6mm pipe and the drain pipe to prevent leakage, then fix the waste water pipe on the drain pipe with a cable tie.(for large flow water purifiers you need to use waste water clip to insert it into the already drilled drain pipe hole)

⑤ RO Membrane Installation

Firstly, take the water purifier and inlet water pipe out from the packaging, open the water purifier outer cover, unscrew the nut from the cap of RO membrane housing, and then, unscrew the membrane shell cover by using the housing wrench. Take the RO membrane from its packaging and put the end of the membrane with O-rings into the reverse osmosis membrane shell firmly. (See

Diagram 9) Finally, tighten the membrane shell cover with the wrench, connect inlet water pipe to the tie-in on the RO membrane shell cover, screw the nut then put the membrane shell into the big clip.

Warnings:

◆ Pay attention to the direction of the membrane when installing the RO membrane,

◆ Make sure that one end of the membrane has tow O-rings When installing the RO membrane,

◆ When installing, be sure to put the end with the O-ring into the end of the membrane shell with the pure water connection, when installing correctly you only need a little force to put the reverse osmosis membrane into the membrane shell, if you encounter too much resistance, please do not force the reverse osmosis membrane into the membrane shell, doing so may cause permanent damage to the membrane shell or membrane components (the membrane manufacturer does not assume responsibility for returned components due to damage during installation);

◆ Damage to the membrane shell and reverse osmosis membrane element caused as a result of the above reasons is not covered under the water purifier warranty.

⑦ Storage tank installation

First wrap Teflon tape around the water nozzle 4-5 times, Smear a little silica gel on it to prevent water seepage if necessary.

Then screw the water tank ball valve into the water nozzle,

Finally connect the water tube: stuff a pipe stopper into both ends of a 6mm tubing with a suitable length, one end of which should be connected to labeled storage tank connector on the water purifier and the other in the storage tank ball valve ,do remember to sleeve the screw nut.

Finally put the storage tank on the base.( See Diagram 10)

Diagram 10

3. Considerations

① When installing the water pipes, cannot install a drain stopper, in addition, for the water pipe bottom connector, the screw nut should have no wire teeth exposed.

② If the inlet water pipe is 9mm, should ensure that the inlet water tube and connector have 30-40cm of straight piping to avoid burst pipe accidents caused by bending in the pipe.

③ If the power cord wiring needs to be longer, then according to the wiring requirements use a Φ8mm pinched tube to wrap around the connection, then on the outside wrap around insulating electrical tape, do not place it on the floor, it should be suspended in the air or in another place away from the ground.

④ When installing, if you need to make a hole in the wall, you should first make sure that there are no electricity or water lines in the location you plan to drill.

⑤ Do connect the power supply wire to the reliable standardized ground wire .If not, the manufacturers will not take any responsibilities caused by safety accidents.

⑥ Water is forbid during installation otherwise electric leakage may happen because of the switching power supply.

Testing

The source of water and power must be confirmed after the water route is connected right. Then follow these steps to troubleshoot the machine:

1. Open the tap water inlet valve as well as the water purifier inlet water ball valve, (See Diagram 11) plug in the power source and wait till the filters are full of water and pure water start to run from the gooseneck faucet.

2. Wait for the water purifier to operate stably (about 5-10 minutes), check each connection to make sure if it is secure and see if there is any leakage from the membrane shell, filters, etc.

3. Close the pure water gooseneck faucet and wait approximately for 30 seconds to check whether the waste water has stopped.

4. Open the gooseneck faucet to see if pure water is flowing, if not, check whether the tap water pressure is too low or whether the high pressure switch cannot be reset.

5. Shut off the inlet water ball valve when the machine is operating, After a while, observe the machine to see if it has stopped, if not ,please check the low pressure switch to see if it can be reset.

6. Only after everything is confirmed right, the water purifier can be used safely

Diagram 11

Usage Methods

1、 The major components of this product are plastic, so please observe the machine constantly to ensure the security while using it.

2、In order to prevent microbial contamination of membrane components during storage and transportation the reverse osmosis membrane element package contains a small amount of protective solution while the post-activated carbon filter will emit activated carbon powder the first time it is used. So for the first hour the water purifier is operated, do not open the water storage tank. It is recommended that the water produced is thrown out, otherwise the pure water taste may be unusual.

3、 When you start operating the water purifier the pure water TDS value may be a little high, after running for some time the TDS value for pure water will gradually decrease until it is stable.

4、When you are using the water purifier, the inlet water ball valve should be opened and the pure water faucet needs to be turned on. When you are not using water turn off the water faucet, the high pressure switch will automatically cut off the water supply.

5、In these

“usage ”, “usage” refers to when the power supply is connected and/or the inlet water ball valve is open so the water purifier is in a working condition.

Maintenance

1、Filter Replacement Time

① This machine‟s filter replacement cycle for the various filters is derived from statistical indicators on average tap water use estimates. If there are big discrepancies between the user‟s actual water quality and utilization rate and the average indicators, there will be more obvious differences between the filter‟s actual use time and the estimated cycle such as premature filter clogging, premature failure, etc. If this happens, filter replacement should be based on actual use, you should also promptly contact your local after-sales service department.

②

This machine‟s estimated filter replacement cycle is based on average household water consumption and is suitable only for residential use, do not install this machine in places that require large volumes of water. If the water volume requirements are large, this company has appropriate machines for business purchase.

③ According to economic statistics on municipal tap water, a three person family on average uses 10L of water a day, according to the water volume and inlet water quality conditions, overall filter volume is approximately as follows (the following data is for reference only):

Ranks Water Volume (tons)

First: 10-inch inline 5-micron PP filter

Second: 10-inch inline granular activated carbon filter

7.5

7.5

Third: 10-inch inline 1-micron PP filter

Fourth: RO membrane

10 depending on the actual water consumption

Fifth: Post-activated carbon filter 6

Note: It is recommended that filter element replacement is carried out by after-sales staff.

Water quality has a great influence on the life of the filter, the RO membrane’s lifespan is affected by many factors, the above table expresses lifespan under standard conditions, in actual usage, because the water quality may be different, the lifespan may exceed the above estimate, it may also be lower than the estimate, this data is for reference only. Under normal circumstances if the following situations are experienced, you should consider replacing the filter:

◆ Poor water quality, taste declines, TDS value of water rises;

◆ Water flow is significantly reduced, check to see if the filter or membrane is blocked (and determine that it was not caused by a temperature drop);

◆

If the filter‟s outer surface is covered in mud or the filter has significantly changed color;

◆ If serious filter clogging leads to no pure water from the water purifier.

2. Filter Replacement Method

① Replacing the 1st and 3rd stage PP filters

Firstly, shut off the inlet water ball valve, unscrew the 1st and 3rd stage filter cartridges by using the filter cartridge wrench and then remove the old filters, take the new filters out of the packaging, finally place the filters in the filter cartridges and tighten the filter cover.

(Note: place the 5 micron PP filter in the 1st stage filter cartridge, the 10-inch 85C granular activated carbon filter in the 2 nd

stage filter cartridge, the 1 micron PP filter in the 3rd stage filter cartridge)
