To Connect: 1. See Figures above. Check and cut the tubing end square and clean with a utility knife or scissors. 2. Make a mark at the end of tubing. The lengh is about 1/2” - the depth of the fitting body. 3. Fully insert the tubing until the mark is almost invisible. This ensures that it is sealed by the O-ring near the bottom. To Disconnect: 1. See Figures above. Remove the blue Lock Clip. 2.
1. 2. 3. 4. Slide the Nut and Collar onto the end of tubing. Fully insert the Insert into the open end of tubing. Slide the Collar toward the Insert and fit into the tapered open end of the thread matal inlet. Screw on the Nut and tighten it up. The Nut compresses the plastic Collar onto the tapered matal surface and creates a water seal between them while the Insert hardens the tubing. How to Drill a Hole in Sink or Counter-top 1.
Installation Steps Before you begin installation, it is highly recommended that you watch the video “iSpring reverse osmosis installation” on YouTube. Note: Steps 1 – 7 are independent, and can be performed in any order. Step 1: Install Feed Water Adapter (AFW) 1.1 See Figures above. Turn off the Cold Water Line via the cold Water Supply Valve (WSV) under the sink. Open the kitchen faucet to release pressure and make sure water has stopped before proceeding to the next step.
Step 2: Install Drinking Water Faucet 2.1 If your kitchen sink does not have an existing 1/2” hole, you will have to drill one. (Refer to How to Drill a Hole in Sink or Counter-top.) Wipe clean and dry the area. (Contact us for a larger front plate and washer if the hole is too big to cover.) 2.2 Remove the blue protection film from the front plate, slip it onto the faucet thread, and slip on the black rubber washer. Insert the faucet thread portion into the hole.
Step 4: Install the Vertical Filters: Stages 1, 2, and 3 4.1 Make sure that the O-ring is seated inside the groove at the top of the filter housing. Foodgrade silicon jelly may be used to help the O-ring stay in place and seal better. 4.2 Filter cartridges are preserved in shrink wrap. Take note of the direction sign on the sticker before removing the wrap (GAC stage). 4.
6.1 Open the membrane housing cap. A thick rubber band can be slipped on the housing body for better grip. 6.2 Find the inner end with 4 O-rings, cut open the end of sealed bag and use it to hold RO membrane to avoid contamination, and firmly insert the membrane into the housing until the outer end with only 2 O-rings is completely inside the housing. See Figure above. 6.3 Before twisting the housing cap back on, check that the O-ring is evenly snagged on the membrane housing (cap does NOT have O-ring).
Step 8: System Start Up (optional sub-steps are marked with * ) 8.1 Make sure that none of the tubings are kinked. Prepare a bath towel and bucket to catch water drips. 8.2 To avoid the residual carbon dust in the first three stages from getting into the RO membrane, remove the tubing to the inlet of the RO membrane housing cap. Flush the first three stages into a bucket until the water turns clear, and re-connect the tubing to the RO membrane. You may do this whenever you change the first three stages.
System Maintenance For replacement filter cartridges, visit 123Filter.com or Google “Model replacement filter” online, in which “Model” is the model number of the system, e.g. RCS5T. Stages 1 – 3 Pre-filters: Replace every 6 – 12 months, depending on source water quality and clean water usage. The frequency depends on the source water quality and clean water usage. They could last longer in city water, and shorter in well water. Different areas have good or bad water.
2. If there is enough room under the sink and filter system is hung on the wall, it could be easier to twist the filter housing off without taking the unit off the wall. Otherwise, it could be easier to pull the system out, lay it down and work towards the housing bottom. Please be careful with tubing connections when pulling the system out. 3. Twist off the filter housing in a counter-clockwise direction when looking from the bottom. Use a housing wrench (the bigger one) if necessary. 4.
2. Disconnect the tubing from the Quick-Connect fitting, unscrew the fitting, unwrap a new cartridge, replace the Teflon tape on the fitting threads if necessary, follow the sign on the label to screw the correct fitting on each end, and reconnect the tubing. O-rings: Replace every 3 years or sooner if leak happens at O-ring. The package comes with 3 spare O-rings for the pre-filter housing, and 1 spare O-ring for the membrane housing. Please save them with this manual.
