Operation
(1) Quick Connect Instruction
It is highly recommended that you watch the video ''How to Connect and Disconnect Quick
Connect Fittings | DIY Installation'' on YouTube.
Cut the tubing end squarely using a utility knife or scissors. Insert the tubing into the quick connect
fitting for at least 1/2''. You will need to wiggle the tube and apply additional pressure to create a
seal.
(2) Install Feed Water Adapter (AFW43) (Optional)
It is highly recommended that you watch the video ''How to Install a Feed Water Adapter for
Reverse Osmosis (RO) and Other Applications | iSpring AFW43'' on YouTube.
Step 1. Turn off the Cold Water Supply Valve (CWSV) under the sink and open the kitchen
faucet to release pressure. Get a towel or bucket to catch any water drips. Disconnect the
kitchen faucet connector pipe from the CWSV.
Step 2. Install the Feed Water Adapter onto the CWSV and tighten it using a wrench or
pliers. Make sure the O-ring is seated inside the adaptor.
Step 3. Re-install the kitchen faucet connector pipe 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 get a proper seal.
Step 4. Connect the 1/4'' tubing to the Feed Water Adapter.
