Installation Steps
Before you begin installation, it is highly recommended that you watch the video
“iSpring reverse osmosis installation” on YouTube.
Note: Steps 1 – 7 are independent, and can be performed in any order.
Step 1: Install Feed Water Adapter (AFW)
1.1 See Figures above. Turn off the Cold Water Line via the cold Water Supply Valve (WSV)
under the sink. Open the kitchen faucet to release pressure and make sure water has stopped
before proceeding to the next step. Get a towel or bucket to catch any water drips.
Disconnect Faucet water hose Connector (FC) pipe from WSV.
1.2 Check O-ring inside AFW female end, and twist it onto WSV. Tighten it up using a wrench
or pliers.
1.3 Twist FC onto the male end of AFW. Turn the handle of AFW to cross (OFF) position.
Turn on WSV slowly, check for and fix any leaks.
