PRODUCT INSTALLATION
STEP 1: 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 ltered 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 the Escutcheon 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 at part of the Plastic Washer is
facing up and the raised area is facing down, 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 rmly 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 2: T-VALVE INSTALLATION
1. Turn o the cold water supply under the sink at the wall.
Then, turn on the cold water to drain the residual water
from the water lines.
2. Disconnect cold water supply line from the supply valve
under the sink at the wall.
3. Connect the bottom of the 3/8-inch T-valve to the cold water
supply valve at the wall. If the water connection is a 1/2-inch
size, use the provided adapters with rubber washers to
connect the T-valve to the supply line.
4. Re-connect faucet water supply hose to the top of the T-valve
as shown, then insert one end of the orange water supply
tubing into the T-valve 1/4-inch Quick Connector. Be sure to
push rmly into place to secure.
NOTE: See next page for tips on how to use Quick Connectors.
5. Make sure the T-valve is in the closed position (valve arm
should be facing up).
Install the T-valve on the cold water supply only.
Never connect to the hot water supply!
You may wish to place a bucket or container under
the pipes to catch any excess water.

Visit brondell.com for our Quick Connect
video tutorial.
Tube connections on the T-Valve, Drain Clamp, Circle, 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 t 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 rst, and then pull the Tube out gently.

MOUNT
DRAIN VALVE
HERE
1. If there is an existing drain connection for a 1/4-inch quick connect tube, then use this connection.
Otherwise, locate a suitable area on the sink drain pipe to install the provided drain clamp.
NOTE: Select a location for
the drain hole based on the
design of the plumbing. It
should be installed above the
trap and on the vertical or
horizontal tail piece. Locate
the drain connection away
from the garbage disposal.
See example to the right.
2. Once a suitable spot has been selected for the drain clamp,
drill a 1/4-inch hole into one side of the pipe. Be sure to
use a suitable drill bit for the material being drilled into (for
example: PVC versus Metal Pipe) and be sure to use safety
goggles.
NOTE: Starting with the 1/8-inch drill bit, drill a 1/8-inch hole
in the drain pipe. Use the 1/4-inch drill bit to enlarge the hole.
If you do not have a 1/8-inch drill bit, then you can just use
the 1/4-inch bit. Clean the debris from the pipe and the hole
before continuing.
STEP 3: DRAIN CLAMP INSTALLATION
WARNING: this step may require drilling into the existing drain pipe. Please seek
professional help when completing this step and always wear safety protection including
safety goggles!
DO NOT drill all the way through the pipe.

3. Align the drain clamp to the hole
a. Take the front half of the drain saddle (with the 1/4-inch
quick connector opening) and unscrew the grey quick
connector from the saddle as shown in diagram 3a.
4. Once the drain clamp is secure and tight on the pipe,
remove the guide and screw the 1/4-inch Quick Connector
back into place.
5. Lastly, insert the white drain tube into the 1/4-inch Quick
Connector on the drain clamp and push rmly into place.
b. Insert a screwdriver, straw, or similar straight thin item into
the front of the rst half of the saddle (to use as a guide) as
shown here in diagram 3b.
c. Insert the end of the guide into the 1/4-inch hole in the
drain pipe and slide the clamp until secure against the
drain pipe. The hole is now properly lined up with the
drain clamp hole. Hold secure by keeping the guide
inserted until the clamp is secured by screwing on the
back side as shown in diagram 3c.

1. Connect the tubes:
a. Connect the open end of the 1/4-inch blue tubing (from
faucet) to the top of the Circle by pushing into the middle
hole labeled “Outlet”.
b. Connect the open end of the white tubing (from the drain
clamp) to the top of the Circle by pushing into the hole
labeled “Drain”.
c. Finally, connect the open end of the orange tubing (from
the water supply T-valve) to the top of the Circle by
pushing into the hole labeled “Inlet”.
d. Be sure to push the ¼”tubing rmly into place to secure.
2. Turn on Water and Check for Leaks
a. Open the T-valve by turning the valve arm 90° and turn
cold water supply back on under the sink at the wall. The cold
water supply will then begin to supply water to the Circle.
b. After turning on the water supply, check all connections for
leaks. Wait 5 minutes and check once more for leaks before
proceeding to the next step.
Failure to properly install this product or to properly
check for leaks may cause damage to the property.
In these instances, Brondell, Inc. will not be held
responsible for any damages.

Problem Possible Cause Solution
My TDS meter is not
reading zero
It could be normal operation or the lters
may need to be changed
Generally, RO systems lower TDS readings
by 90% as compared to tap water readings.
This is a normal working range. For example,
if your tap water TDS reading is 100, then a
normal TDS reading for the RO ltered water
is in the range of 0–10. If the TDS reading for
the RO ltered water is higher than 15% of
normal tap water, this indicates it time for a
lter change (including RO membrane).
