If a reverse osmosis water filtration system is connected to your cold water supply, the water pressure to the reverse osmosis system needs to be a minimum of 40 to 60 psi (276 to 414 kPa).
If the water pressure to the reverse osmosis system is less than
40 to 60 psi (276 to 414 kPa):
■Check to see whether the sediment filter in the reverse osmosis system is blocked. Replace the filter if necessary.
■Allow the storage tank on the reverse osmosis system to refill after heavy usage.
■If your refrigerator has a water filter, it may further reduce the water pressure when used in conjunction with a reverse osmosis system. Remove the water filter. See “Water Filtration System.”
If you have questions about your water pressure, call a licensed, qualified plumber.
Connect the Water Supply
Read all directions before you begin.
IMPORTANT: If you turn the refrigerator on before the water line is connected, turn the ice maker OFF.
Connect to Water Line
1.Unplug refrigerator or disconnect power.
2.Turn OFF main water supply. Turn ON nearest faucet long enough to clear line of water.
3.Find a ¹⁄₂" to 1¹⁄₄" (12.7 mm to 3.18 mm) vertical cold water pipe near the refrigerator.
IMPORTANT:
■Make sure it is a cold water pipe.
■Horizontal pipe will work, but the following procedure must be followed: Drill on the top side of the pipe, not the bottom. This will help keep water away from the drill. This also keeps normal sediment from collecting in the valve.
4.Determine the length of copper tubing you need. Measure from the connection on the lower right rear of refrigerator to the water pipe. Add 7 ft (2.1 m) to allow for cleaning. Use ¹⁄₄" (6.35 mm) O.D. (outside diameter) copper tubing. Be sure both ends of copper tubing are cut square.
5.Using a cordless drill, drill a ¹⁄₄" hole in the cold water pipe you have selected.

6.Fasten the shutoff valve to the cold water pipe with the pipe clamp. Be sure the outlet end is solidly in the ¹⁄₄" drilled hole in the water pipe and that the washer is under the pipe clamp. Tighten the packing nut. Tighten the pipe clamp screws slowly and evenly so the washer makes a watertight seal. Do not overtighten or you may crush the copper tubing.
7.Slip the compression sleeve and compression nut on the copper tubing as shown. Insert the end of the tubing into the outlet end squarely as far as it will go. Screw compression nut onto outlet end with adjustable wrench. Do not overtighten.
8.Place the free end of the tubing in a container or sink, and turn ON the main water supply. Flush the tubing until water is clear. Turn OFF the shutoff valve on the water pipe.
Connect to Refrigerator
Depending on your model, the water line may come down from the top or up from the bottom. Follow the connection instructions for your model.
Style 1
1.Remove plastic cap from water valve inlet port. Attach the copper tube to the valve inlet using a compression nut and sleeve as shown. Tighten the compression nut. Do not overtighten. Confirm copper tubing is secure by pulling on copper tubing.
2.Create a service loop with the copper tubing. Avoid kinks when coiling the copper tubing. Secure copper tubing to refrigerator cabinet with a “P” clamp.

3.Turn on water supply to refrigerator and check for leaks. Correct any leaks.
Style 2
1.Create a service loop (minimum diameter of 2 ft [61 cm]) with the copper tubing. Avoid kinks when coiling the copper tubing.
2.Remove the plastic cap from water valve inlet port. Place a compression nut and sleeve on the copper tubing.
3.Insert the end of the copper tubing into the water valve inlet port. Shape tubing slightly so that the tubing feeds straight into the port to avoid kinks.
4.Slide the compression nut over the sleeve and screw into the water valve inlet port.
