The Coral Undercounter Water Filtration System is not designed to remove beneficial
minerals from your drinking water. These minerals that occur naturally are a healthy
part of your drinking water and should remain. The Brondell Coral Undercounter
Water Filtration System is designed to dramatically reduce water-soluble harmful
contaminants, including industrial chemicals, pesticides, herbicides, turbidity,
volatile organic compounds (VOCs), and microorganisms, most of which cannot be
"read" with a TDS reader.
Since these harmful components are water-soluble, they cannot be picked up by a
simple TDS meter. Contrary to its name (Total Dissolved Solids or TDS Meter), these
inexpensive products cannot detect most harmful water-soluble contaminants.
There is a major misconception that low TDS readings mean healthy water and that
is simply not always true.
The best method for testing the performance of a water filtration device is to have
a nationally recognized independent organization, such as WQA (Water Quality
Association) or NSF International, test and certify the products. The certified data
is then available in a Performance Data Sheet, which you should request from the
manufacturer. For more clarification of what the Coral Undercounter Water Filtration
System does remove from your water, please see our Certified Performance Data
Sheets on pages 21-23.
IMPORTANT NOTE ABOUT
“TDS METERS” AND TESTERS
Q) When I use a Total Dissolved Particle (TDS) reader to test my water
after it goes through the Coral Undercounter Water Filtration System,
why don't the levels of dissolved particles go down or decrease? I don’t
think the product is working.

PRODUCT INSTALLATION
STEP 1: T-VALVE INSTALLATION
Do not install the Filter Head Connection Asssembly further than 12 feet away from
either the water supply valve, or the Indicator Faucet.
Avoid unnecessary slack in the supply hoses when connecting to the water supply, Filter
Head Connection Assembly, or Indicator Faucet.
Do not install in direct sunlight, or a place where it will be directly exposed to freezing
temperatures.
Be sure to install the T-Valve on the cold water supply line. Running hot water through
the Coral Water Filtration System will damage the filters.
1. Close the cold water supply valve. Place a bucket, or similar
item, underneath the valve to catch any water that may spill
out during installation.
2. Unscrew the hose that connects the cold water supply valve
to the existing tap water faucet.
3. Ensure the rubber washer is inside the T-Valve, and then
screw the T-Valve Adapter onto the cold water supply valve.
NOTE: If the water supply valve is smaller than the 1/2”
connection on the T-Valve, use the included 3/8”Valve
Adapters with Rubber Washers to connect the T-Valve and
the water supply hose.
4. Screw the cold water supply hose to the top of the T-Valve.
Be sure to keep the water supply valve closed.

STEP 2: FAUCET INSTALLATION
Before Installation
You will need an existing faucet hole at least 7/16
inches in diameter in the sink or countertop to install
the supplied filtered water faucet. You may also
replace an existing kitchen sprayer, soap dispenser,
or plug already on the countertop or sink.
1. Unpack the faucet and insert the Top Spout into the Main
Body by pushing down until inserted then screw the Top Cap
clockwise until secured in place.
2. Cut zip tie on the blue water connection tubing and unroll
to straighten tubing. Be careful not to cut the tube when
removing the zip tie.
If drilling a new hole is required for the
faucet installation, please consult a
professional. Brondell will not be liable
for any damages including those to the
sink or countertop due to installation of
the faucet or drilling a hole.

3. Attach the Escutcheon to the Main Body by inserting the
blue tubing through it and pushing it all the way up until
connected to the Main Body.
4. Install the faucet on top of the countertop or sink and feed
the blue tubing through the hole to the cabinet below. Then
slide the large Plastic Washer as shown up through the blue
tubing until snug against the bottom of the countertop or
sink hole. Be sure that the flat part of the Washer is facing
down and the raised area is facing up as shown here.
5. Install the Lock Washer and the Locking Nut the same way
and tighten until the plastic washer is holding the faucet
assembly firmly in place. The faucet is now installed.
6. Pull the plastic tab out from the battery compartment to
activate the faucet indicator. The LED light will blink red
once, blue once, and then will be ready to go.

STEP 3: FILTER HEAD CONNECTION ASSEMBLY INSTALLATION
Be sure to install the Filter Head Connection Assembly so that the top of the assembly is
at least 14 inches from the floor of the sink cabinet. Otherwise the filters will not install
or seat correctly.
2. Using a pencil, mark where the Filter Head Connection Assembly will be mounted to the sidewall
of the cabinet (at least 14”from the cabinet floor). Use a level to make sure that the Assembly will
be mounted straight.
NOTE: Before you mount the Connection Assembly, it may be a good idea to practice inserting
and removing the filters.
3. Insert the two mounting screws through the holes in the Assembly frame and screw into the
cabinet sidewall.
1. Attach the two Quick Connect 90° Elbows to back side of the Connection Assembly Inlet and
Outlet as shown

STEP 4: INSTALLING THE FILTERS
1. To insert the filters, first line up the arrow on the filter head
with the arrow on the filter
NOTE: For purchasers of the Coral UC300, it is very important to install the filters in the correct
order. Simply match the same label colors to the filter head labels. From left-to-right, the
proper order is
1) Sediment filter
2) Pre-Carbon filter
3) Carbon Block filter
2. With the top and bottom arrows
still lined up, insert the top
of the filter into the housing
and turn 90 degrees to the
right, until the filter will not
turn any more.
The Filter Head arrow should
now be lined up with the“Circle”
icon and notch on the top
of the filter.
3a. For UC300 – Repeat the process for the Pre-Carbon filter and
Carbon Block filter.
3a. For UC100 – This process is complete.

STEP 5: CONNECTING THE TUBING
1. Water Supply Connection
Use the supplied white color Water Supply Tubing to connect the T-valve to the Filter Head
Connector Assembly by pushing one end of the tubing firmly into the Quick Connector
Collette on the open side of the T-Valve. Be sure to push in all the way and ensure the Tube
is not bent or kinked.
Then connect the other open end of the Tubing to the Filter Head Connector Assembly “Inlet”
by inserting the tube into the Collette on the Quick Connect 90 (degree symbol) Elbow on the
side labeled “Inlet” (nearest to the Sediment filter)
Using "Quick Connectors"
Tube connections on the T-Valve, Filter Head Connection Assembly, and Indicator Faucet are all of
the“Quick Connect” variety. The steps below illustrate how to connect and disconnect the Tubes
from these connectors.
a. Push the Tube into the Collette. The Collette is a collar that
provides a secure fit for the Tube and prevents water leaks.
b. Push the Tube in until it stops. The Tube will be secure, and
resistant to tugs or pulls. The Collette will be rigid and raised
slightly from the connector housing.
c. To disconnect the Tube, push down and hold the Collette first,
and then pull the Tube out gently.
2. Faucet Connection
Now, connect the open end of the Blue Tubing coming from the Faucet to the Filter Head
Connector Assembly “Outlet”by inserting the Tube into the Collette on the Quick Connect 90°
Elbow on the side labeled “Outlet” (nearest to the Carbon Block Filter). Be sure to push in firmly
all the way and ensure the Tube is not bent or kinked.

FILTER CHANGE INDICATOR
FILTER REPLACEMENT CYCLE
Contact Brondell at 888-542-3355, or visit us at www.brondell.com to order replacement filters.
The filters are critical to the performance of the Coral UC Water Filtration system, and it is
important to replace all of the filters on a regular basis. If any of the filters are overused beyond the
recommended service life, the performance of the water filtration device can deteriorate. Do not
miss the filter replacement cycle or use non-compatible filters as this can affect system performance
or damage the unit.
The LED filter change indicator in the faucet works by tracking both time and water flow from the
Coral UC system.
UC300 – When 12 months have elapsed or 600 gallons of water has been filtered through the system
(whichever comes first), the LED will flash red when dispensing water instead of flashing blue.
UC100 – When 6 months have elapsed or 300 gallons of water has been filtered through the system
(whichever comes first), the LED will flash red when dispensing water instead of flashing blue.
When the faucet LED indicator begins to flash red, it’s now time to change the filters and reset the
faucet indicator by replacing the battery.
A new battery is always included with the UF-35, or UF-15 filter replacement set.
* The filter replacement cycle may be reduced for areas with poor water quality or greater use.
** The period for the filter exchange is based on an average production of 1.64 gallons of
drinking water per day.
