Installation Steps
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
proceed
ing 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” RED tubing to the Feed Water Adapter.
