Before you begin the installation, it is highly recommended that you watch the

video "iSpring Reverse Osmosis Installation" on YouTube.

Note: If you plan on mounting/hanging the system, it is highly recommended to

include supports under each of the bottom three housings. Supports under the

housings will take the water weight off the housing threads, and ensure the thread strength does not

decay over the years.

Note: Steps 1 – 7 are independent, and can be performed in any order.

Step 1: Installing the Feed Water Adapter

(The bushing can convert 3/8" comp. to ½" NPT.)

1.1 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. Disconnect the

Kitchen Faucet Connector (KFC) pipe from the CWSV.

1.2 Check to make sure the O-ring is seated inside the Feed Water Adapter 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 Feed Water Adapter. Turn the handle of the Feed

Water Adapter to the perpendicular OFF position. Turn on the CWSV slowly, and ensure

you are getting a proper seal.

1.4 Connect the 1/4"

Feed Water Adapter with Bushing to convert

3/8" COMP to 1/2" NPT
