Note: Steps 1 – 7 are independent, and can be performed in any order.
Step 1: Installing the Feed Water Adapter (AFW43)
(The bushing can convert 3/8” comp. to ½” NPT. Refer to AFW43 user manual)
1.1 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 make sure 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.
1.2 Check to make sure the O-ring is seated inside the AFW43 female end, and twist it onto the CWSV.
Tighten it using a wrench or pliers.
1.3 Twist the KFC onto the male end of the AFW43. Turn the handle of the AFW43 to the perpendicular
OFF position. Turn on the CWSV slowly, and ensure you are getting a proper seal.
1.4 Connect the 1/4” RED tubing to the AFW43.

Step 2: Installing the RO Faucet
2.1 If your kitchen sink does not have an existing ½” faucet hole, you will have to drill one. (Refer to How to
drill a Hole on Sink or Counter-top). Wipe clean and dry the area.
2.2 Slip the front plate on the faucet stem, followed by the rubber washer. Insert the faucet stem into the hole
on the countertop. Under the sink, slip on the back rubber washer, and tighten the nut with the plastic
wing.
2.3 Slide the Nut, then the Collar onto the end
of the tubing.
2.4
Push the Tube Insert into the open end of
the tubing.
2.5
Insert the tubing into the threaded faucet
stem.
2.6
Screw the Nut tightly onto the threaded
faucet stem.
2.7
This compresses the Tube Collar and
Tube Insert to create the seal between the
tubing and faucet.
