Step 1: Set up Feed Water Adapter (AFW)

1.1    Look at figure five. Shut off the Cold Water Line through the cold water supply Valve beneath the sink. To lessen pressure, expose the kitchen faucet and be sure water stops prior proceeding to the next phase. Pick up a bucket and towel to grasp water drips.

Separate Kitchen Faucet Connector (KFC) pipe as of CWSV.

1.2 Confirm O-ring within AFW female end and curl it onto CWSV. Exercise pliers or wrench to tighten the screwup.

1.3 Coil KFC to the male end of AFW. Shift the handle of AFW to irritable location. Start CWSV slightly, notice and fasten a leak.

1.4 Attach the 1/4” RED tubing with AFW.

Step 2: set up Drinking Water Faucet

2.1 If in your kitchen sink there remains no half hole, you need to drill a hole. Wipe it well and make the area completely dry. Make contact with us for the bigger front plate as well as washer since the gap is very big to cover.

2.2 Take out blue protection film from the frontage plate, trip it on the valve thread and fall on the black rubber like a washer. Go into the faucet thread part into the gap. Sealer or plumber glues may be applied.

2.3 Beneath the sink, tighten the black rubber washer and lastly fasten washer with the nut.

2.4 Glide the firmness fitting nut and the collar of the BLUE tubing, push the insert with the tubing, enter it in the faucet end and then tighten up the nut. Draw the tubing to notice if this is safe enough.

Step 3: Set up Drain Saddle

1.1    Select a spot over the drain pipe which is suitable for setting up the tubing and the drain saddle. Horizontal pipe is suggested to lessen the soaked sound.

3.2 Make a ¼ inch hole to the pipe of the drain; attach the muggy black pad surrounding the hole.

3.3 Slash the BLACK tubing end somewhat to make a 45-degree angle. Trip the plastic nut as well as a forward plate of the tubing.

Enter the tubing in ¼ inch hole in the pipe of the drain, adjust the back plate as well as tighten two screws by hex nuts when the tubing stays in the gap.

3.4 Tauten the nut of the Drain burden with hand. Draw the tubing to see if it is safe.

Step 4: Put in the Vertical Filters: Stages one, two and three

4.1 Be happy to know that the O ring is set inside the channel to the summit of the filter lodging. Food graded silicon jelly can be applied to aid the O ring to keep in the right place as well as seal better.

4.2 Filter cartridges are reserved in shrink enfold. Take a note of the indication mark on the sticker before removing the wrap.

(GAC stage).

4.3 Keep the filtering cartridges with the housing, surely it is in the middle and lump protrude from the underneath of the housing fits the center hole of the filter.

4.4 Add screw to the housing, having filters joined up the shelter caps. The lid holds a center knob that must be entered into the main gap of the filter cartridge. Bend the housing to the clockwise direction with hand, and use a housing wrench to tighten up for ¼ to ½ turn. It is wise not to tighten more. It can create leaks, and it would be tuff to unscrew the housing if replacing filters.

4.5 Notice the step from 1.1 to 1.4 to set up the GAC and CTO filter.

Note: The 2nd stage GAC is the one filter which has to go in a certain direction. Be sure that the end along with the rubber washer ahead so add by housing cap.

Step 5: Set up Tank Shut-off Valve (TSV)

5.1 Enfold ten to 15 turns to Teflon tape clockwise with the metal thread to the up of the tank.

5.2 Use screw with the Tank turns off valve on then tighten up with your hand. Surely do not tighten much.

5.3 Attach the YELLOW tubing on the Quick-adjust of TSV.

Step 6: Put in Reverse Osmosis Membrane

6.1 Release the membrane housing screw cap. At first, you have to disconnect the white ¼ inch tubing out of the Intel Quick-fitting in the membrane housing cap and after that detach the cap. Finally, a chunky rubber band may be slipped on the housing body by the stronger handhold.

6.2 Take out the membrane from the sealed bag. Go to the flow direction sign to the membrane and tightly enter the membrane with the housing to the smaller end which has two black O ring heads. At first, the bigger ending is with the housing opening. Notice figure 8 to 9.

6.3 Prior twisting the housing cap behind a notice that the O ring is snagged with the membrane housing. Hang firmly and tighten up for ¼ to ½ turns applying a little plastic housing wrench. Better not to tighten more. It is wise not to connect the tubing with a cove on the lid to this point.

Step 7: Tubing clasp up (model definite sub-steps are marked with * )

7.1 Look at figure five and figure six then RCC7P and RCC7 TOP VIEW, note adding points A-B, C-D, E-F, and G-H.

7.2 Toward the iSpring logo up ahead, the pre-filter first stage is added to the right-hand side. Add the RED tubing Feed Water Adapter with the elbow fitting.

7.3 Add the Flow Restrictor that is a three inches long cylinder having a flow signal remaining besides the membrane housing toward the Drain Saddle along with Black tubing.

7.4 To the right side of the Post Carbon Filter, add the Tee-fitting and the Tank Valve to the Yellow tubing.

7.5 * Model without UV/AK/DI: To the last section of FT15, enter the BLUE tubing to the elbow fitting.

* Model with UV/AK/DI: RO water goes out of the point G at FT15 and runs toward the left end of the following.

Therefore the Blue tubing must be added to the last end of the ultimate stage that may be the AK/ UV/ DI filter.

7.6 Add another end of the BLUE tubing with the RO faucet.

7.7 You can arrange the tubings but keep more length. Therefore, the filter is possible to move easily in and out of the cabinet if replacing filters.

7.8 You can hang the system with the help of two 10 x 1-1/4 Phillips Flat Wood Screws. It may make the replacing filter cartridges easier.

Step 8: Structure Start-Up (model definite sub-steps are manifest with * )

* As the model comes with a UV stage, it is better not to plug in power along with the system that is completely flushed.

8.1 Be sure that all tubings are not bent. Shutdown Shut Off valve. Keep a bath towel to hold water leak.

8.2 To give up residual carbon in the first three states from getting to the RO membrane, the tubing with the inlet of the RO membrane housing cap is needed to keep disconnected. Flush the first three stages of the bucket, and then water comes out clear and finally re-connects the tubing with the RO membrane.

8.3 Open the Feed Water Adapter Valve and after that slow start the cold water supply valve.

Notice any leakage. There are main three causes of leaks 1) The tub is not completely entered to the quick connect fitting 2) the cap. Housing is not enough tightened up or off thread 3) the O ring is not to the right place or kinked.

8.4 * Switch on booster pump power if you have bought one.

8.5 Within five minutes, RO must begin dripping. Keep it open for at least ten minutes. It flushes the system excluding the tank. Water is black for loose carbon from the new carbon filters. By the help of some air bubble, it will turn into clear.

8.6 Turn off the RO Drinking Faucet. Start the Tank Shutoff Valve. Pass some time to fill up the tank. In warm summer it can take up to 1.5 hours or in cold winter, it will take 3 hours to fill up a 3.2 gallon tank having about 3.5 gallons keeping capacity.

8.7 After 2 hours, start the RO Drinking Faucet to flush out whole water in the tank. It is forbidden to use the first tank of water. The water comes out of the faucet may be stronger as the water pressure is built up to 35 to 40 psi if filled it up. Since the water flow changes again to a trickle, it indicates that the tank is vacant.

8.8 * Connect the UV power and notice as the RO faucet moves the UV off and on by the Flow Sensor Switch.

8.9 The reverse osmosis membrane is the main effective thing to remove total dissolved solids. The taste of water will be great if the system works properly. When the TDS of the source water is 100 ppm, the RO water must be less than 10 ppm.

8.10 After setting up the system notice if there is any leak for the first two weeks. Besides a bucket may be kept under the system in the case of any leaks. A Flood Alarm may be utilized for more protection.

Alkaline Update

This is a concern of follow-up that I have pH water and have original FA 15 alkaline filter appear with RO system. The installation date is December 2015. The customer service is excellent and useful.

In January 2016, they send me an FX15 3 stage alkaline filter without any cost as I told them the pH is around six instead of more than seven.

The main screen has two stages. I measured it with three stages filter and found the pH is below 7. For my mistake, it was over 8.

I use the pH test strips made of saliva and used for urine testing instead of water testing. I become confirm as I bought a bottle of alkaline water which said pH is 8 in level.

Alkaline Update

It was 7 in my test strips. The water was more alkaline coming out of the 3 stage FX 15 filter that I purchased from the store.

There is a picture in which it is shown the level of alkaline of the two stages and three stages side by the side of the RO water which has no alkaline filter. The result of the blue color is dramatic though there is no pH number.

I need test strips to test my drinking water. I have the procrastinated on, and I would like to post it for the readers who are thinking about the pH. My family likes the water of the RO system, and I am happy with the service of the iSpring.
