System Installation

Prior to Installation

Inspect the package

Open the box and remove all of the components. Inspect them to ensure nothing was damaged during shipping. If any part is cracked or broken, please immediately contact iSpring Customer Support for a replacement. Identify and get familiar with the components.

Recommended tools list

● Variable speed drill with two bits: ¼” (for drilling a hole on PVC drain pipe), ½” hollow
diamond (for drilling a hole on countertop for drinking faucet)
● 5/8”, 9/16” open-end wrench, or adjustable wrench, pliers
● Phillips head screwdriver
● Scissors or utility knife

Operating conditions

● Minimum water pressure: 45 PSI, otherwise a booster pump is necessary to raise the
incoming water pressure and improve the RO efficiency.
● Maximum water pressure: 70 PSI, otherwise a pressure regulator (part no. APR70) is
required to lower the PSI to the maximum level.
● Operating water temperature range: 40 – 100 °F (4 - 37 °C) (This RO system is NOT
designed for HOT water). The RO process will be slightly faster the warmer the source water is and vice versa.
● Maximum TDS: 750 ppm
● Install this RO system in a location where it is safe from hot/cold weather and direct
sunlight. Avoid hitting, dropping, or dragging the system as this can cause cracks and leaks.

The UV filter is typically the final stage for all RO UV systems, but can be moved in front of the 1st stage if the incoming water is already clear.

Installation Tips

Figure 1

How to use the Quick-Connect fittings

To connect:
1. See Figure 1. Check and cut the tubing end squarely and cleanly with utility knife or
scissors.
2. Make a ⅝” mark at the end of the tube so you will be able to confirm when the tube is
inserted fully into the fitting.
3. Remove the blue lock clip from the fitting with your nail. If the lock sleeve pops out of the
fitting when doing this, simply pop it back in.
4. Insert the tube into the fitting until you reach the ⅝” mark on the tube. You will feel
resistance when the tube reaches the small rubber O ring inside the fitting. You will need to wiggle the tube and apply additional pressure to get it passed this O ring and create the seal.
If the tube is not ⅝” into the fitting and past the O ring, no seal will be created and leaking will occur.
5. Once the tube is fully inserted into the fitting, pop the blue lock clip back on the fitting. This
will lock the tube in place and prevent it from moving.
Figure 2
Figure 3
To disconnect:
1. See Figures 2 and 3. Remove the blue lock clip from the fitting.
2. With the blue lock clip removed, use your thumb and index finger to hold down the lock
sleeve. This will release the metal teeth holding the tube in place. While holding the lock sleeve down with that hand, use your other hand to remove the tube from the fitting.

How to drill a ½” hole in your sink or counter-top

1. It’s highly recommended to watch the YouTube video “How To Drill Faucet Holes” to
get a better understanding of the process. Depending on what kind of countertop you have, you may want to hire an experienced professional to ensure the hole is drilled correctly.
2. Choose a half inch Diamond Core Bit for granite, and a titanium drill bit for steel. Do NOT
use a hammer drill on nature 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 breaking through the slippery surface. Some people found it is easier to secure the bit by drilling through a piece of wood that is firmly pressed on the surface.
5. Use 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. Starting at slowest speed, hold the drill firmly and vertically and prevent the drill bit from
slipping on the counter.
7. Once breaking through the smooth surface, swirl the drill a little to apply pressure in a circle
evenly.
8. Be patient and deliberate. It can take 20 – 40 minutes to drill through one inch.

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 proceeding 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.

3/8” COMP to 1/2” NPT

Step 2: Installing the RO Faucet

2.1 If your kitchen sink does not
have an existing ½” faucet 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.
2.2 Slip the front plate on the
faucet stem, followed by the rubber washer. Insert the faucet stem into the hole on the countertop. Under the sink, slip on the back rubber washer, and tighten the nut with the plastic wing.
2.3
Slide the quick connecting up
the push-in adapter on the base so that it seats securely into the faucet stem, then lock it in place by sliding the blue clip under the collet.
2.5 Insert the BLUE tubing about
1/2 inch into the push-in
and again, secure it with the blue clip.
fitting,

Step 3: Installing the Drain Saddle

3.1 Choose a spot on the drain pipe that is convenient for installing the drain saddle and tubing.
A horizontal pipe is recommended to minimize the dripping sound.
3.2 Drill a 1 /4” hole in the drain pipe, and paste the black sticky pad around the hole.
3.3 Cut the BLACK tubing end to make a 45 degree angle. Insert the tubing into the 1/4” hole
in the drain pipe, install the back plate, and tighten the two screws with hex nuts while the tubing remains in the hole.
3.4 Insert Lock Clip. Pull the tubing lightly to make sure it is secure.
