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 Figure 5. Turn off the Cold Water Line via the Cold Water
Supply Valve (CWSV) 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 Kitchen Faucet Connector (KFC) pipe from CWSV.
1.2 (Refer to AFW user manual). Check O-ring inside AFW female end,
and twist it onto CWSV. Tighten it up using wrench or pliers.
1.3 Twist KFC onto the male end of AFW. Turn the handle of AFW to
cross (OFF) position. Turn on CWSV slowly, check and fix any leaks.
1.4 Connect the 1/4” RED tubing to AFW.
Step 2: Install Drinking Water Faucet
2.1 If your kitchen sink does not have an existing ½” 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.
(Contact us for larger front plate
and washer if the hole is too big to cover).
2.2 Remove blue protection film from the front plate, slip it on the faucet
thread, and slip on the black rubber washer. Insert the faucet thread
portion into the hole. Optional plumber glue or sealer could be used.
2.3 Under the sink, tighten the back rubber washer, lock washer with nut.
2.4 (Refer to How to use compression fitting). Slip the compression fitting nut and collar on the BLUE tubing,
push the insert into the tubing, insert it into the faucet end, and tighten up the nut. Pull the tubing to check if
it is secure.
