System Installation Prior to Installation *Installation is to comply with all local laws and regulations* Inspect the package Open the box and remove all of the components. Inspect them to ensure nothing was damaged during shipping. If any part is cracked or broken, please immediately contact iSpring Customer Support for a replacement. Identify and get familiar with the components.

Page 4 www.123filter.
Understanding the Booster Pump and RO Process 1. Source water enters the system and passes through the stage 1, 2, and 3 pre-filters. Located between the pre-filters is the Lowpressure Switch. This switch turns on when the incoming water pressure is 6 psi or greater. 2. The High-pressure Switch turns on when the pressure from the pressurized tank is below 20 psi, and turns off at 45 psi (e.g., when the tank is full). 3.
Installation Tips How to Use the Quick-connect Fittings Figure 1 To Connect: 1. See Figure 1. Check and cut the tubing end squarely and cleanly with a utility knife or scissors. 2. Make a 5/8" mark at the end of the tube so you will be able to confirm when the tube is inserted fully into the fitting. 3. Remove the blue lock clip from the fitting with your nail. If the lock sleeve pops out of the fitting when doing this, pop it back in. 4.
To Disconnect: 1. See Figures 2 and 3. Remove the blue lock clip from the fitting. 2. With the blue lock clip removed, use your thumb and index finger to hold down the lock sleeve. This will release the metal teeth holding the tube in place. While holding the lock sleeve down with that hand, use your other hand to remove the tube from the fitting.

Step 1: Installing the Feed Water Adapter (AFW43) (The bushing can convert 3/8" comp. to 1/2" NPT. Refer to AFW43 user manual) Step 1. a. See Figure 5. Turn off the Cold Water Line via the Cold Water Supply Valve (CWSV) under the sink. Open the kitchen faucet to release any pressure and ensure the water has stopped before proceeding to the next step. Get a towel or bucket to catch any water drips. Disconnect the Kitchen Faucet Connector (KFC) pipe from the CWSV. Step 1. b.
How to install an Air-gap Faucet (optional) Note: The installation instructions below are for your reference only. An air gap faucet is not included with this system. • Drill a hole in the kitchen sink or countertop if there isn't already a spare one. Refer to the manual of the faucet when determining the size. • Place the front plate and the rubber washer on the base of the faucet. Mount the faucet on the countertop. • From under the sink, connect the RO system pure water output line to the faucet stem.
Step 4: Installing the Vertical Filters: Stages 1, 2, and 3 Step 4. a. Make sure the O-ring is seated inside the groove on top of the filter housing. A light amount of food-grade silicone jelly may be used to help the O-ring seal better but is not required. Step 4. b. The filter cartridges are preserved in shrink wrap. Note the direction sign on the sticker before removing the wrap. Step 4. c.
Step 6. e. Before twisting the housing cap back on, make sure the O-ring is seated at the end of the membrane housing, as shown in figures 12 and 13. This is very important to avoid leaking and damage to the O-ring. Step 6. f. Place the membrane housing cap back on, hand tighten it, then use the housing wrench to tighten it another 1/4-1/2 of a turn. Do not over tighten. Step 6. g. DO NOT reconnect the tubing to the fitting on the cap at this point (will be done in system startup).
Figure 16 Step 7. a. See figure Sample Installation and figures of system top view and note connection points A-B, C-D, E-F, and G-H. Step 7. b. Facing the system's front, 1st stage is the see-through housing located on the righthand side. Connect the RED tubing Feed Water Adapter (AFW43) (point A) to the stage 1 elbow fitting (point B). Step 7. c. Connect the Flow Restrictor (point C, 3" long cylinder with a FLOW labeled on it) to the Drain Saddle (point D) with the BLACK tubing. Step 7. d.
disconnected. Open the Feed Water Adapter Valve (AFW43) and Cold Water Supply Valve (CWSV), and flush the first three stages into a bucket until the water turns clear. Step 8. c. Once the water is clear, shut off the AFW43 and reconnect the tubing to the RO membrane housing cap. You will want to flush the first three stages like this whenever they are changed. Step 8. d. Open the RO faucet. Slowly open the AFW43 back up and check for any leaks.
OWNER’S MANUAL Please read this manual for useful reverse osmosis system maintenance information. Section 1: iSpring RO System Maintenance All iSpring RO systems are designed with ease of use and low maintenance in mind. If the filter cartridges are changed on schedule as suggested, the system will work properly for years to come. See the chart below for the filter pack model numbers for your system. The filter packs can be found on 123filter.com, Amazon, or HomeDepot.com.
Figure 17 Note: Stages 6 and/or 7 only exist on specific models. Stage 1 – 3 Pre-Filters Replace every 6 months or sooner if you notice a decrease in water flow or quality. The replacement frequency depends on your water usage and source water quality. Changing the prefilters according to the schedule is essential to protect the RO membrane from chlorine and other damaging contaminants. How to change the stage 1 – 3 pre-filters: 1.
How to Change the Reverse Osmosis Membrane Figure 18 Figure 19 1. The RO membrane typically lasts about 2 – 3 years. The membrane life span depends on the source water quality, water usage, and how often the three pre-filters are replaced. It is essential to replace the pre-filter cartridges on schedule to ensure their performance and water purity. Use a TDS meter to check the RO water purity periodically. 2.
Optional Add-on Ice Maker Kit (ICEK) The Ice Maker Kit (model#: iSpring ICEK) can be purchased separately to feed RO water to your refrigerator for crystal clear ice cubes and great tasting water. If you choose to hook up the system to your refrigerator output, it can take the place of primary output over the RO faucet.

Section 2: Troubleshooting Guide for Newly Installed Systems w/ Booster Pump Figure 22 1) Zero output water from RO faucet a) Water supply is closed. Open the water supply to the system, so the valve is in line with the red tubing. b) Incorrect installation. Verify all tubing connections. c) The pump is not running, therefore not allowing water through. Make sure the pump is plugged into a live outlet that gets continuous power. d) A tubing is crimped, blocking the water flow.
4) Leaking from between the membrane cap and membrane housing a) If the membrane housing is leaking, make sure the O-ring is seated correctly, as shown in 5) 6) 7) 8) 9) 10) 11) 12) sections "Installing the RO Membrane" and "How to Change the RO Membrane." It should be seated on the end of the membrane housing before the threads begin. The membrane cap is then screwed on over it. When positioned incorrectly, it will create a gap or damage the O-ring.
