Reverse osmosis uses a special kind of semi-permeable membrane designed to function similarly to living cell’s membrane. The membrane can be conceived of as having tiny pores, 200 times ner than virus particle and 4000 times ner than most bacteria. The principle of reverse osmotic water purication is modelled after living cell’s natural water cycle. It allows to remove all noxious impurities from water including nitrate, microorganisms, and anthropogenic pollutants. Only certain types of molecules pass through the membrane lter.

Standard model MO 5-50 ltration system operates the following way.

Filter rack 1 is connected to cold water line by installing feed adapter 4 and feed water valve 5 (see Figure 3.1). Red tube connects feed water valve with pre-lter 10.1 in the lter rack 1 so that feed water rst undergoes the three stages of pre-treatment in pre-lters

10.1, 10.2, 10.3. Inside the pre-lters, water is stripped of suspended solids, chlorine and organochlorines, rust, and other impurities that can foul or damage the RO membrane.

Outlet of pre-lter 10.3 is connected to feed inlet of the automatic shuto valve 12, which is a four-way valve fastened to the frame of lter rack. Automatic shuto valve controls switches the whole RO system on and o by opening feed when there is not enough water in the pressure tank 2 (e.g. when some water is taken from the faucet) and closing feed when pressure tank is full.

Feed outlet of the automatic shuto valve is connected to the inlet in membrane housing on top of the lter rack, which contains the RO membrane 10.5. Membrane housing has two outlets — one for puried water (permeate), and the other for water containing the retained impurities (concentrate). Water owing into the RO membrane undergoes reverse osmosis and separates into the two streams. Concentrate is discharged into drain pipe, and permeate is accumulated in the pressure tank 2 and dispensed from the faucet on demand.

Permeate outlet of the membrane housing is tted with a check valve to prevent backow and wasting puried water. It is connected with permeate inlet in the automatic shuto valve 12, and permeate outlet of the shuto valve is connected with union tee 11. Another

2. Principle of operation

outlet of the union tee is connected to the pressure tank (by means of yellow tube running to the tank valve 6), and the third outlet of the tee is connected to carbon post-lter 10.4. All described components are connected to one another with exible tubes.

The purpose of the pressure tank 2 is accumulating and storing puried water, the need for which arises due to slow nature of reverse osmotic purication of water. For instance, if the system is tted with a 50 gpd membrane, 200 ml cup will take over 1,5 minutes to ll if the membrane was directly connected to faucet without a tank. In order to compensate for the small production rate, drinking water is puried in advance and stored in the tank, which is pressurized so the water will run at an ample rate. When completely drained, the pressure tank takes about 1,5 hours to ll.

Concentrate with the retained impurities is discarded from the second outlet in membrane housing, connected with the drain saddle 8 with the black tube. In order to operate properly, the system requires a backpressure on concentrate line, which is created by ow restrictor 14 — a plastic insert with calibrated throttle orice. Flow restrictor is inserted in the black tube and must face the membrane housing when the tube is connected.

When faucet is opened, puried water is drawn from the pressure tank through the postlter 10.4. Рost-lter is a coconut shell activated carbon lter. Its purpose is to remove any taste and odor imparted to puried water while in the tank, especially if stored for longer periods of time and/or at warmer temperatures. Carbon taste and odor lter outlet is connected to the faucet 3 by means of blue tube.

Additional equipment

Booster pump 16 for reverse osmosis system is an option. It is purposed to increase feed water pressure in the system in case supply pressure is not sucient to operate the system with the specied rate of drinking water production. We recommend that you t your system with a booster pump or purchase an RO system with a booster pump if the pressure in your water supply line is less than 3 bar.

UV disinfection unit 17 is an option. The unit is necessary when protection against emergence of downstream microbial contamination is essential.

Re-mineralizing lter 15 is an option and is included in models that produce mineralenriched water alongside regular reverse osmotic water.Mineral composition of water (approximate) after re mineralizing is specied on product label.

Before installing the system, it is necessary to prepare a place under the kitchen sink. Make sure that there is sucient space for the system and the pressure tank. In case there is not enough empty space under the kitchen sink it is acceptable to install the pressure tank separately from the system within yellow tube stretching distance.

Note

It is preferable to install the system in places protected from direct sunlight.

1. Remove the RO system from its packaging and check the assembly.

2. Shut o water supply in your kitchen or whole home and open water tap where you are about to install the system (on your kitchen sink) for 1 minute to relieve pressure in the system, and then close it.

3. Install the feed adapter into the cold water line, take feed water valve from the set and join it to the feed adapter.

Note

Feed adapter is ½″ sized. If your pipe is a dierent size, use an appropriate reducer tting.

4. Unscrew the coupling nut of the feed water valve connection and put it on the red tube. Insert the red tube into the outlet of the valve and screw the coupling nut back on. Connect the other end of the red tube to the quick connect tting of the rst pre-lter.

5. Connect the drain saddle with drain pipe from the kitchen sink. The drain saddle is compatible with most standard drain pipes. Drill a hole of 5,0 mm diameter in the kitchen sink drain pipe, apply rubber gasket with sticky base (included in the kit). Install the drain saddle on the drain pipe over the hole. Tighten nuts on drain saddle with a wrench. Insert black tube into the connection on the clamp (gure 4). For instruction on using quick connect ttings, read chapter 6.

6. Put a few turns of PTFE tape on the thread on tank outlet. Screw the tank valve onto the tank outlet. Close the tank valve.

7. Install the faucet according to the instructions in chapter 5.

8. Select spot where you are going to install the lter and make two holes. The distance between the holes in the wall must precisely correspond to that between the holes in the bracket. Allow for at least 100 mm gap between the bottom of the lter and oor. Install screw

anchors if necessary and screw in two screws (not included).

9. Connect the exible tubes. Layouts for each system model are given in gures 3.1, 3.2, 3.3.

10. Install cartridges in the rst and second bowl per water ow direction as in Figure 5. Screw the bowls back on. Bowl should be turned with hands, do not use wrench.

11. Disconnect the tube that connects the third bowl (per water ow direction) with the automatic shuto valve.

12. Open the feed water valve and ush 5-7 liters of water through the rst two bowls with cartridges.

Note

Water may spill from the free end of the tube, prepare a container to collect it.

13. Insert the cartridge into the third bowl (per water ow direction), screw the bowl into the lter and repeat washing procedure as described in the above paragraph with at least 4 more liters of water to wash the coal dust. Close the feed water valve and connect the free end of tube back to the automatic shuto valve.

14. Install the membrane (if it was not pre-installed at factory) in its housing on top of the lter rack in accordance with the scheme in Figure 6.

15. Slowly open the feed water valve with the faucet opened. After squeezing the air out of system, check if the water ows freely from the faucet.

Note

The air trapped in the system can take as long as 3 days to purge completely, in the meantime of which the system may produce milky/cloudy drinking water or water with dust-like lm on its surface. This is caused by tiny bubbles of air that had dissolved into the water and is not a malfunction.

16. Leave the feed water valve open for 30 minutes. Close faucet and carefully check all connections for leaks. Turn the tank valve open.

Note

During the rst week of use check the system for leaks daily. It is also recommended to check it routinely afterwards. If you have to leave for extended periods of time, such as a business trip or a vacation, shut o water supply to your system.

17. When the tank is full (and you cannot hear water owing in the system any longer) drain all the water from the tank into the kitchen sink by opening the faucet. When water pressure is released, close the faucet to rell the tank. Depending on supply water pressure, lling the tank can take 1,5 to 3 hours. When the tank is lled for the second time, the water in it can be used.

1. To prepare for installing the faucet drill a hole with a diameter of 12,5 mm in a suitable spot on the kitchen sink or counter.

Caution

Metal chips can damage the sink, it is necessary to remove them carefully immediately after the hole is drilled. If you are installing the faucet on a ceramic or stone xture, use a special carbide drill bit.

2. Mount the faucet on the counter top as shown on the scheme in Figure 7. Put the rubber

gasket on top of the hole and seat the faucet in it. Put on plastic gasket, lock washer, and nut on the shank of the faucet sticking through at the bottom side of the hole. Screw the nut all the way up until the faucet is rmly xed on the counter top.

3. Take the blue tube, put compression nut on it, then put on compression ring, then put plastic insert inside the blue tube.

4. Push the blue tube as deep as possible into the bottom of the faucet’s shank, ensuring the compression ring is in the joint. Screw on the compression nut in order to join the tube to the faucet.

After you have completed installation, faucet must be rmly xed at the counter top, and the blue tube rmly joined to the shank of the faucet.

Connecting the tubing does not require using any tools. The entire system is connected together as shown on gures 3.1, 3.2, 3.3, depending on your model.

To release tube (or a plug) from a quick connect tting, rst remove the locking clip (horseshoeshaped red plastic clip), push the collet back against the body of the tting and then gently pull out the tube, while keeping the collet depressed (see gure 8). If the tube does not yield, you may not be pushing the collet deep enough. Make sure you push the collet evenly and strongly enough toward the body of tting.

In order to join a tube or plug to the tting simply push the tube all the way into the tting. After joining the pipe to the tting, put on a locking clip under the collet to secure the connection as shown in gure 9. To check the connection you have made try to pull the tube outwards as shown in gure 10.

6. Using quick connect ttings

* If quality of water supplied to the system does not meet the specied requirements, service

life of membrane and cartridges may be reduced.

** If pressure of your water supply is lower than required, purchase a system with a booster pump or t RO system that you already own with one. If pressure in your water supply is higher than the specied maximum pressure, a pressure reducing valve should be installed before the RO system.

If you use wellwater to supply your household utilities, it is advisable to perform chemical analysis of your water before installing an RO ltration system. If any of the parameters exceed the limit, consider using a water treatment system to bring supply water quality to within specication. To select proper equipment, refer to specialists or companies professionally engaged in water treatment.

Ecosoft reverse osmosis system can only be used with cold water supply.

Pre-lter cartridges should be replaced in a regular and timely manner, once in 3 months or more often. Failure to do so will increase fouling load on the membrane and may cause it to wear out prematurely. Generally, if your RO system takes signicantly more time to rell the tank (before switching o) than it would take with new cartridges and membrane, the membrane and pre-lter cartridges may need to be replaced.

If you are resuming after a prolonged (more than 2 weeks) period of non-use, rst drain all stored water. Open the faucet 3, wait until water stops running, then close the faucet and wait until the tank is full again. When the tank is relled, you may resume using the water.

Using UV lamp beyond the recommended service life is disapproved, since the intensity of UV radiation and its germicidal eciency will be reduced.

1. Disconnect the UV lamp power supply.

2. Shut o feed water valve, tank valve and the faucet.

3. Remove the black PVC cap through which the electric cable passes

4. Remove the lamp from the quartz sleeve by pulling on its base. Do NOT touch the bulb!

5. Disconnect the power plug holding the lamp by its base.

6. Insert the new lamp half way into the quartz sleeve.

7. Properly connect the power connector.

Caution

UV lamps should be handled with care and only held by the ceramic ends, because contaminating the quartz surface will reduce germicidal eciency and shorten service life. Use cotton gloves while handling UV lamps.

8. Push the lamp all the way into the housing and put the PVC cap back on.

9. Restore the supply of water to the unit and check for tightness and absence of leaks.

10. Plug the adapter into a socket and verify that the new UV lamp is working properly.

Ensure green indicator light in power supply adapter is on.

Caution

It is strongly forbidden to turn on the UV lamp power when the lamp is not in metal housing, and to look at a glowing lamp. This can lead to eye damage and result in deterioration or loss of vision.

When replacing the UV lamp it will also be useful to clean the quartz sleeve.

Do not use abrasive materials to clean the sleeve, as this may decrease transparency of the sleeve to UV radiation, thereby reducing the eciency of disinfection.

Be careful when removing the quartz sleeve from the housing to avoid damaging or scratching the sleeve.

Carefully remove sealing rings from the ends of the sleeve. The rings serve to protect the lamp and electrical connections from water leaks.
