Please follow the four color-coded tube connections to complete the installation.
Tubing Connection Guide Cut the tubing squarely, and insert tubing into the lock fitting (be sure the lock fitting is flush for a secure insert). Push tubing inward while pushing the lock fitting outward and insert the lock pin. Pull on the tubing gently to ensure it is tightly fitted. CAUTION: Before cutting supplied tubings, predetermine the length by measuring the distance between the components to be connected.
Preparation Determine the location for installation of the RO system. Determine the location for installation of the RO faucet. You may use the existing predrilled hole on the sink. Make sure the washer is big enough to cover the hole. If you drill a new hole on the countertop or sink, make sure that drilling the hole will not damage any pipe or wiring underneath the countertop or sink. Determine the location for the water storage tank.
Installation A. RO Faucet Installation The RO faucet may be installed on any flat surface. Check the underside of the location for any interference. You may use the existing predrilled hole on the sink. Make sure the washer is big enough to cover the hole. If you drill a new hole on the countertop or sink, make sure that drilling the hole will not damage any pipe or wiring underneath the countertop or sink. 1. Determine the desired location for your RO faucet on your sink surface. 2.
B. Porcelain Sink To drill on a porcelain sink, a spring-loaded Relton-style drill set is strongly recommended in order to prevent chipping. Avoid high speed drilling during the initial cutting of porcelain as this can cause chipping. See the following figures.
Recommended drill bit set for a porcelain sink C. Feed Water Supply Installation Tapping into the COLD WATER line CAUTION: The water supply to the unit MUST be connected to the COLD WATER LINE. HOT WATER will severely damage your RO System. 1. 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 make sure the water has stopped before proceeding to the next step. Get a towel or bucket to catch any water drips.
Feed Water Adapter with Bushing to convert 3/8” COMP to 1/2” NPT 5. Connect the feed water tubing to the RO system. Once the feed water adapter has been installed, connect the tubing (RED) to the first stage (clear housing) of the RO system.
D. Mounting the Drain Saddle Valve A Drain Saddle Valve is used to make a waste water connection with the drain under the sink and is designed to fit around a standard 1 1/2-inch OD drain pipe. The drain saddle valve should always be installed before (above) the p-trap and on a vertical or horizontal drain. To avoid clogging the drain line with debris, do not install the drain saddle near a garbage disposal. 1. Choose a spot on the drain pipe that is convenient for installing the drain saddle.
E. Install the Tank Ball Valve NOTE: Do not tamper with the air valve on the lower side of the storage tank. It has been preset at 8–10 psi by the manufacturer. 1. Unplug the plastic cap on the top of the tank. 2. Wrap the thread three times with plumber’s (Teflon) tape only. 3. Connect the ball valve to the thread. Make sure it is tight, but not overly tight. 4. Place the storage tank in the desired location either horizontally or vertically. 5.
below. 2.) Remove the membrane housing from the plastic mounting clip. Remove the membrane housing’s end cap by turning counterclockwise as shown in the diagram below. 3.) Insert the RO membrane cartridge into the housing as shown in the diagram below. The O-rings on the product water tube of the RO membrane cartridge MUST FULLY SEATED in the membrane housing for proper operation. Also, make sure that the Brine Seal on the membrane seals with no gaps or wrinkles inside the membrane housing.
System Start-Up Make sure ALL the tubing is connected to the correct locations. Double-check the security of all connections before TURNING ON the water supply. See the following checklist. A. ) The faucet tubing connects to the inline filter (5th stage). One end of the inline filter is marked “connect to faucet.” (3/8” blue tubing) B. ) The feed water tubing connects to the 1st stage of the unit. C.
1. Turn on both the cold water supply and the undersink feed water valve, and close the tank ball valve. If any leaks are noted, turn off the valve and correct before proceeding. 2. Open RO faucet for continuous flow. 3. Check the system for leaks; tighten where necessary. 4. After five minutes, the water will start to drip out of the RO faucet. Let it drip for about 10 minutes and then flip the handle to the closed position. Turn on the tank ball valve.

Preventative Maintenance The following recommendations will help your system achieve maximum efficiency in RO water production. 1. Filter maintenance a. Filters may be stored for several years. b. Place the sealed unopened filter in an airtight container to prolong its shelf life and prevent it from absorbing unwanted odors. 2. Membrane maintenance a. The dry-packed membrane typically has a two-year shelf life. To prolong the shelf life, keep the unopened dry membrane in the refrigerator. b.
Note: If the housing is too tight to open, try unplugging the fitting or tubing in order to release the air and water pressure inside the housing. e. After opening the housing, remove the used filter and put the new filter into the housing. Make sure the O-ring is in place, turn the housing counterclockwise to close, and tighten. f. Repeat the previous step on the second filter change. g. Turn on the water supply and make sure there are no leaks. h. Let the water drip from the faucet for about 10 minutes.
Cleaning Procedures The following system and tank cleaning procedures are recommended to be done every 12-18 months. 1. Shut off the source water supply to the RO system. 2. Open the RO faucet and depressurize the RO system and storage tank. 3. Remove the pre-filter cartridges, post-filter cartridges, and RO membrane. Discard or prepare them for cleaning.
b. Fill the tank sanitizer feeder with the recommended amount of disinfectant, and connect the feeder to the water supply and RO storage tank. c. Turn on the water supply and force the water and disinfectant solution into the RO storage tank. The storage tank should feel heavy when filled. d. The disinfectant solution should remain in the tank for a minimum of 10 minutes. If the tank has not been sanitized in more than a year, leave the solution in the tank for 20 to 30 minutes.
Troubleshooting Note: Turn off the system before servicing or inspecting. PROBLEM CAUSE Milky colored water √ Air in system SOLUTIONS o Air in the system is a normal occurrence with the initial startup of the RO system. The milky appearance will disappear with normal use within one to two weeks. Noise from faucet √ Air gap faucet o Will cease after system shuts down. √ Location of drain saddle o Relocate the drain to above the water trap.
