2) Water Treatment Process
Municipal Tap Water → PP Sediment Filter → GAC Filter →CTO Filter →RO Membrane →
Deionize Filter → Purified water
3) Operating Conditions
•Maximum water pressure: 70 psi, or a pressure regulator (part# APR70) is required if there is
high water pressure or water hammer.
•Minimum water pressure: 30 psi for model#RCC1DP, 45 psi for model#RCC1D, or an extra
booster pump is needed to improve RO efficiency
•Install this RO system where it is protected from hot/cold weather and direct sunlight. Avoid
hitting, dropping, or dragging as they may cause cracks and leaks.
Understanding the Booster Pump and RO Process
1. Source water enters the system and passes through the stage 1, 2, and 3 pre-filters. Located
between the pre-filters is the Low-pressure
Switch. This switch turns on when the
incoming water pressure is 6 psi or greater.
2. The High-pressure Switch turns on
when the pressure in pure water line is below
20 psi, and turns off at 45 psi.
3. When the Low-pressure Switch and
High-pressure Switch are both on, the Feed
Water Solenoid Valve opens, allowing water
to the Booster Pump.
4. The source water passes through the
Booster Pump, bringing it to approximately
100 psi entering the membrane housing.
5. Coming out of the RO membrane is a
pure water port and wastewater port. The RO
water is forced through the .0001 micron-sized
holes of the RO membrane and exits through
the one-way Check Valve on the membrane's
pure water exit port. The water rejected by the
RO membrane exits through the wastewater
exit port. On the drain line before the
wastewater is disposed of is the Flow
Restrictor, limiting the amount of drain water
allowed out to keep pressure in the system.

Step 1: Water Inlet – Three Options
Water Inlet Option 1 –
Connect from Cold Water Valve Under Sink w/ 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.
Step 1. a. 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 1. b. 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. Plumber's tape may be used to seal the
connection.
Step 1. c. 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 1. d. Connect the 1/4'' RED tubing to the Feed Water Adapter.
The included bushing can be threaded on either side of the Feed Water Adapter to fit the configuration
of both 3/8'' COMP and 1/2'' NPT.
Water Inlet Option 2 –
Connect from Kitchen/Bathroom Faucet w/ 156F34GH + 34GH14K Connectors
Step 1. a. Remove the aerator from the faucet. Your hands should be enough, but pliers can be
used. Save the aerator, which may be needed if the system is removed.
Step 1. b. Screw the 156F34GH adaptor onto the 34GH14K connector, then screw the whole
connector onto the faucet. Usually, the connectors can be hand tightened; if necessary, use a
plier. Plumber's tape may be used to seal the connection.
Step 1. c. Connect the 1/4'' RED tubing to the 34GH14K connector.
Water Inlet Option 3 –
Connect from Garden Hose Bibb w/ 34GH14K Connector
Step 1. a. Twist the 34GH14K connector onto the garden hose bibb by hand, then use a plier to
tighten it as needed. Plumber's tape may be used to seal the connection.
Step 1. b. Connect the 1/4'' RED tubing to the 34GH14K connector.

Step 2: Install Drain Saddle (ADS1K)
It is highly recommended that you watch the video "How to Install iSpring Drain Saddle (ADS1K)
for Reverse Osmosis (RO) System | DIY Installation" on YouTube.
Step 2. a. Choose a proper spot anywhere before the P-trap on the drain pipe to install the drain
saddle and tubing. Remember that the drain saddle should NOT be installed after the P-trap
to prevent potential microorganism growth.
Step 2. b. Drill a 1 /4" hole in the drain pipe, and paste the black sticky pad around the hole.
Step 2. c. Cut the BLACK tubing end to make a 45° 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.
Step 2. d. Insert Lock Clip. Pull the tubing lightly to make sure it is secure.
Step 3: Install the Vertical Filters: Stages 1, 2, and 3
Step 3. a. Make sure that the O-ring is seated inside the
groove at the top of the filter housing. Food-grade
silicone jelly may help the O-ring stay in place and
seal better.
Step 3. b. Filter cartridges are preserved in shrink wrap.
Note the direction sign on the sticker before
removing the wrap.
Step 3. c. When placing the filter cartridge into its
housing, make sure it is centered, and the knob is
protruding from the bottom of the housing fits in the
central hole of the filter.
Step 3. d. Screw the housing, with filters attached, onto
the housing caps (caps are pre-assembled on the
machine head). The cap also has a center knob that
should be inserted into the center hole of the filter
cartridge. Twist the housing on in a counter-clockwise direction by hand, and then use a
housing wrench to tighten it up for about 1/4 – 1/2 turn. Do not overtighten. This can cause
leaks and make it difficult to unscrew the housing when replacing filters.
*Note* the second stage GAC is the only filter that must go in a certain direction. Make sure that
the end with the rubber washer faces up, attaching to the housing cap.

Step 4: Installing the Reverse Osmosis Membrane
Step 4. a. Disconnect the tubing from the quick-fitting connection on the membrane cap.
Step 4. b. Open the membrane housing cap. A thick rubber band can be slipped on the housing
body for better grip.
Step 4. c. Find the inner end with 2 O-rings, cut open the end of the sealed bag, use it to hold
the RO membrane to avoid contamination, and firmly insert the membrane into the housing
until the outer end without the O-ring is completely inside the housing. See Figure above.
Step 4. d. Before twisting the housing cap back on, check that the O-ring is evenly snagged on
the membrane housing. Hang tight and tighten up for about 1/4 – 1/2 turns using a small
plastic housing wrench, but do not over tighten. DO NOT reconnect the tubing to the inlet on
the cap at this point (will do it in system start-up).

You may neatly organize the tubing, but make sure to leave enough length so the filter system
can be moved freely in and out of the cabinet when replacing filters.

Page 11 www.123filter.com | [phone] | [e-mail]
Step 6: Leak Stop Valve (ALS1) Installation
The Leak Stop Valve is a reusable mechanical leakage protector. Whenever a water leakage is
detected, it will shut down the feed water.
Step 6. a. Make sure the end of the tubing is cut square before connecting it to the fitting.
Step 6. b. Follow the water flow direction indicated on the Leak Stop Valve to connect it to the
water inlet pipeline.
Step 6. c. Tape the bottom of the Leak Stop Valve against the floor.
Step 7: Mounting the System (Optional)
•Mounting the system is NOT required. The system does NOT need to be
mounted to work correctly.
•Please note if the system is to be mounted, it is recommended to use two 10
x 1-1/4 Phillips Flat Wood Screws (not included). This will make replacing
filter cartridges easier.
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.
Step 8: System Start-up
Note for model#RCC1DP: You may now plug in the booster pump to an outlet. The pump will
not turn on until the water is flowing.
Step 8. a. Make sure no tubings are kinked. Place a towel under the system to catch any possible
water leaks.
Step 8. b. Disconnect the RO membrane housing cap inlet tubing. Turn on the water inlet, and
flush the first three stages into a bucket until the water turns clear. The water may appear
black at first due to loose carbon from new carbon filters.
Step 8. c. Once the water is clear, shut off the water inlet and reconnect the tubing to the RO
membrane housing cap. You will want to flush the first three stages like this whenever
they are changed.
Step 8. d. Open the pure water outlet. Slowly open the water inlet and check for any 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. 3) The Housing/Cap is not
tightened properly or is misaligned with the threads.

www.123filter.com | [phone] | [e-mail] Page 12
Step 8. e. Within 5 minutes, the booster pump on model#RCC1DP will kick on, and the RO
water will start slowly trickling from the pure water outlet. Let the water trickle for at least
15 minutes to flush out the entire system. It will eventually turn clear apart from many tiny
air bubbles leaving the system.
Step 8. f. Shut off the system.
Step 8. g. The TDS (total dissolved solids) of the water should be tested periodically to verify
that the system is performing properly. iSpring RO systems have exceeded the minimum
requirements for NSF/ANSI standard 58. They should be giving an average TDS reduction
rate of 90%+, so if your tap water is 100 ppm, you should be getting 10 ppm or less from the
RO water (200/20>, 400/40>, etc This reverse osmosis system contains a replaceable
treatment component critical for the effective reduction of total dissolved solids. That product
water should be tested periodically. TDS is measured with a TDS meter - it is an inexpensive,
easy-to-use device that can be found on Amazon.com or 123filter.com by searching "iSpring
TDS."
Step 8. h. Check for leaks daily for the first two weeks after installation to ensure the system is
functioning properly. Install the Flood Alarm (optional, model: WD01) to provide additional
peace of mind and protection.
Note: Do not use microbiologically unsafe water or unknown quality without adequate disinfection
before or after the system. Systems certified for cyst reduction may be used on disinfected water that
may contain filterable cysts.
System Maintenance
All iSpring RO systems are designed with ease of use and low maintenance in mind. If the filter
cartridges are changed on schedule as suggested, the system will work properly for years to come.
See the chart below for the filter pack model numbers for your system. The filter packs can be found
on 123filter.com, Amazon, or HomeDepot.com.
1-Year Filter Pack
2-Year Filter Pack
3-Year Filter Pack

F15-150
F22-150
*Please note, the general filter cartridge replacement schedule is for reference only. Not all filters
included in the same filter pack, Carefully choose the filter pack that suits your RO system.
*Filter replacement schedule may vary depending on the quality of your source water.

When to change the filter?
The filters are highly suggested to be replaced when they reach their recommended replacement cycle.
However, the actual lifespan of filters may vary depending on the source water quality and daily
usage. If you notice a great decrease in the tap water flow or detect an unpleasant smell, taste, and
odor, it would be a good time to get your filters changed.
How to change the filters?
Carefully follow the instructions that come with the filter package.
O-rings: Replace every 3 years or sooner if a leak happens at the O-ring.
The package comes with spare O-rings for the pre-filter housing and the membrane housing. Please
save them with this manual.
What should I do with the system when going out of town?
When you leave for an extended time, you will want to shut off the water supply to the system. To
do this, shut off the water inlet supply, and open the pure water outlet until it stops running. The
filters should be replaced if the system is not used for over a week, as they will be sitting in stagnant
water.
Leak Stop Valve Pads (ALS1P3) Replacement
It is highly recommended that you watch the video "Absorb Pad Replacement of iSpring Leak
Stop Valve | Easy DIY | Step by Step" on YouTube.

Cloudy water
after installation
a. In the weeks after installing
the system or changing the
filters, you will see many tiny
air bubbles in the RO water.
This can cause the water to
appear "cloudy."
a. The bubbles will disappear as the
system clears itself of trapped air and
are harmless for the time being.

Page 15 www.123filter.com | [phone] | [e-mail]
Pump does not
start
a. No power.
b. Incoming water pressure is
below 30 psi.
c. Low-pressure switch is not
functioning correctly.
a. Make sure the pump is plugged in. If
it is plugged in and still not kicking on,
make sure it is not plugged into the
same outlet as the garbage disposal.
Typically this outlet only has power
when the garbage disposal is switched
on.
b. Increase the incoming water pressure,
such as adding a booster pump.
c. Contact the iSpring Customer Service
Team for replacement.
Pump runs 24/7
