- Step 1. Install Feed Water Adapter (AFW43)
- 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.
- Turn off the Cold Water Supply Valve (CWSV) under the sink and open the kitchen faucet to release pressure. Prepare a towel or bucket to catch any water drips. Disconnect the kitchen faucet connector pipe from the CWSV.
- Step 2. Install Drinking Water Faucet
- Drill a hole to install the faucet
- Install a faucet bracket (included) instead of drilling a hole (Optional)

- Step 5. System Start-up
- Make sure no tubing is kinked. Place a towel under the system to catch any possible water leaks.
- Open the drinking water faucet. Slowly turn on the Feed Water Adapter (AFW43) and check for leaks. The top 3 causes of leaks are 1) The tubing is not fully inserted into the quick-connect fitting. 2) The O-ring is not in the correct place or is kinked...
- Rinse the system for 5-15 minutes. It is normal to see residual carbon and fine air bubbles in the water when flushing the system for the first time.
- Check for leaks daily for the first two weeks after installation to ensure the system is functioning properly.

How to Drill a Hole in Sink or Counter-top
1. It is highly recommended that you watch the YouTube video "How to Drill Faucet Holes."
2. Choose a 1/2" Diamond Core Bit for granite and a titanium drill bit for steel. Do NOT use a
hammer drill on natural stone, glass, and ceramic.
3. An indent should be made with a punch on steel before drilling to help guide the bit.
4. Use caution when drilling on a Porcelain sink, as it could be easily chipped - set drill speed
on slow. Press the bit downward firmly until it breaks through the slippery surface.
5. Use a coolant to disperse heat. Choose water for granite and oil for steel. Use the Water
Suction Cup to hold coolant inside and prevent the drill bit from slipping.
6. Hold the drill firmly and vertically at the slowest speed to prevent the drill bit from slipping
on the counter.
7. Once you break through the smooth surface, swirl the drill a little to evenly apply pressure
in a circle. Be patient and deliberate. It can take 20 - 40 minutes to drill through 1".
Step 3: Install the System
A. Place the system on a flat surface.
B. *(Optional) Match the stage labels and twist filter cartridges counterclockwise into the machine
head in order.
C. *(Optional) Use the included screws to hang the system on the wall.
