Keep in mind that you may install a tube tee on the line to the faucet to connect icemakers
or other faucets to the system. If you locate your system farther than 20 feet from the
faucet, you will need to use 3/8” tubing or install a pressure booster pump to your line. See
your dealer for parts and details.
Step 2. Getting Ready
1. Clear working area. Unpack all components and check for visual damage. Ensure all
listed components are included.
2. Inspect the cold water supply line and the condition of the pipe. The water supply adapter
included is intended to be installed between the supply valve and the faucet connector,
under the kitchen sink. If the cold water supply valve is not available at the installation
location, you will need to consult your plumber or plumbing supply store to purchase an
appropriate cold water connection.
3. Check the air pressure in the RO storage tank with an ordinary tire gauge. It should be
pre-charged to 7-10 PSI. Adjust if necessary. DO NOT EXCEED RECOMMENDED TANK
INFLATION PRESSURE
– UNIT WILL FAIL TO OPERATE CORRECTLY.
4.
You will need the following tools: An electric drill, a ½” carbide bit, a ¼” carbide bit, a 1/8”
carbide bit, a pencil, a small adjustable (crescent) wrench, a sharp knife (X-Acto type knife
is best), Teflon plumbing tape, adjustable pliers, a rat-tail file, a center punch, a medium flat
head screwdriver, a small household funnel. Always wear eye protection when using an
electric drill.
Step 3. Install the Cold Water Supply Faucet Adapter
1. Turn OFF the COLD water supply valve to your kitchen faucet.
2. Turn ON the COLD water on your kitchen faucet to release all the pressure, and completely
drain the cold water until the water flow stops.
3. Place some towels underneath the cold water supply valve and then disconnect the faucet
supply tube from the cold water supply valve.
4. Wrap male threads on both cold water supply valve and the water supply adapter 4 to 5
times
with plumber’s (Teflon) tape.
5. Install the water supply adapter on the cold water supply valve. Do not over-tighten.
6. Install the faucet supply tube to the water supply adapter.
7.
Connect the white ¼” tube to the water supply adapter by inserting the tube firmly and
pushing until the tube end contacts the stop. Gently tug the tube backwards to assure a
secure connection. In the same way, connect the other end of the tube to the RO system
water inlet.
8. Keep the COLD water supply valve OFF until the RO system installation has been
completed; turn the COLD water supply valve ON and check for leaks around the water
supply adapter. Tighten, reseal or reinstall if necessary.
