Drill the Faucet Hole (if necessary)
The faucet can be installed through a standard faucet hole or spray hose
hole in your sink, if one is available. If no hole is available, use the following
instructions to drill a faucet hole. If a faucet hole is already available, skip to
section Connect the Faucet (pg 6).
1. Select and mark the faucet mounting spot on the sink.
a. Conrm that there are no reinforcing ribs under the desired faucet
location.
b. If you have an extra hole in your sink for a spray hose, you may also
choose to disconnect the spray hose and use that existing hole for
the CB-As faucet.
2. Use the hammer to gently tap the center punch on
the sink location where the hole is to be drilled. This
creates an indentation to mark the drilling location.
3. If you have a porcelain, ceramic, or cast acrylic sink:
CAUTION: Porcelain, ceramic, and cast acrylic
surface materials are extremely hard and can easily
crack or chip. Use extreme caution when drilling. CB
Tech is not responsible for any damages resulting
from faucet installation.
a. Use the 1/2” carbide-tipped masonry drill bit to grind away a small
section of sink veneer down to the metal, clearing enough space to
allow drilling without damaging the rest of the sink surface veneer.
b. Carefully use the 7/16” high-speed steel drill bit to completely drill a
hole through the metal sink.
CAUTION: Do not allow the drill bit to “grab” the sink veneer, as this will
damage the surface.
4. If you have a stainless steel or metal sink:
a. Use the 1/8” high-speed drill bit to
drill a pilot hole.
b. Use the 7/16” high-speed drill bit to
completely drill a hole through the
metal sink.

5. If you have a granite countertop:
CAUTION: Granite surface materials are extremely hard and can
easily crack or chip. Use extreme caution when drilling. CB Tech is not
responsible for any damages resulting from faucet installation.
a. Place a towel or basin under the sink, directly under the location of
the intended faucet hole.
b. Using a snake of plumbers putty, form a circular “dam” around
the location of the intended faucet hole. Make the dam 5” in
diameter and 3/4” tall.
c. Fill the dam with cool tap water. The water will keep the drill bit from
overheating.
d. Use the 1/2” granite drill bit to drill the hole. Slowly grind away the
granite material.
Connect the Faucet
Proceed to the instructions for your faucet type:
1. For a standard faucet, proceed to section Installing the Standard
Faucet (Pg 6).
2. For a capacity-monitored faucet, proceed to section Installing the
Capacity Monitor Faucet (Pg 8).
Installing the Standard Faucet
NOTE: The blue plastic tubing is attached to the faucet.
1. From the sink / countertop:
a. Place the larger soft black rubber washer over the faucet hole.
b. Place the cover plate on top of the large washer.
c. Place the smaller soft black rubber washer on top of the cover plate.
d. Place the faucet base over the smaller soft black rubber washer
and atop the cover plate.
2. From under the sink:
a. Slide the hard plastic black washer (with the smaller side up)
upward over the blue tubing.
b. Slide the lock washer upward, below the hard plastic washer.
c. Slide the wing nut upward, below the lock washer.
d. Hand-tighten the wing nut to secure the faucet.

1. From the sink / countertop:
a. Place the large rubber washer (#9) over the faucet hole.
b. Place the LED Display Plate (#7) on top of the large rubber washer.
Feed the attached black cable down through the hole in the sink.
Rotate the LED Display Plate so that the indicator light will be easy
to see.
c. Place the small rubber washer (#6) on top of the LED Display Plate.
d. Place the faucet base (#3) over the small rubber washer and
LED Display Plate. Feed the faucet stud (#4) and blue tubing (#5)
down through the hole in the sink. The faucet stud should now be
accessible below the sink.
2. From under the sink:
a. Slide the black track washer (#10) (with the at side down) upward
over the threaded faucet stud. Guide the black wire (#8) through
the track to protect the wire and prevent it from becoming pinched
between the sink and the stud nut.
b. Slide the hard plastic washer (#11) upward over the blue tubing
(#5), black track washer (#10), black wire (#8), and faucet stud
(#4).
c. Slide the lock washer (#12) upward over the faucet stud, below
the hard plastic washer.
d. Screw on the stud wing nut (#13) below the lock washer.
e. Hand-tighten the wing nut to secure the faucet.
3. Prepare the Filter Monitor Unit (FMU)
a. Guide the black wire (#8) from under the sink to the Filter Monitor
Unit (#14), and plug it into the top of the FMU.
b. Open the FMU and pull out the battery holder. Insert two (2) AA
batteries (not included) into the battery holder, making sure to
match the + and – signs. Reinsert the battery holder.
c. Press and hold the check/reset button on the FMU for six (6)
seconds. You should hear a long audio sound, and the LED Display
Plate will ash red and then green several times.
d. Snap the cover back onto the FMU.
e. Peel off the paper backing from the hook-and-loop connector
strip, and attach one piece to the back of the FMU.

f. Select a clean, convenient mounting location on a wall beneath
the sink, allowing sufcient space for placement of the FMU. Peel
off the paper backing from the second hook-and-loop connector
strip and attach it to the desired wall location.
g. Attach the FMU to the wall using the two hook-and-loop connector
strips.
4. Prepare the Filter Monitor Unit
a. Attach the two lter monitor adapters (#15) to the FMU (#14), one
on each side.
b. Complete the installation after connecting the tubing.
5. Connect the Tubing from the Housing to the Filter Monitor Unit
NOTE: Complete this step only after
the CB-As tubing has been connected
in section Connect the Tubing to the
Housing (Pg 14).
a. Fully insert the blue plastic tubing
from the CB-As OUTLET into the
adapter (#15) on the INLET (#5)
side of the FMU; the tubing should
typically be inserted 5/8” into the
adapter. The inlet side is the side
from which the arrow points away
on the capacity ow device.
NOTE: When pushing the tubing
into the adapter, you will encounter
some resistance. This does not
mean that the tube is fully inserted.
Continue to push rmly until the
tubing is inserted as far as possible
(roughly 5/8” into the adapter).
6. Connect the Tubing from the Faucet to the Filter Monitor Unit
a. Fully insert the blue plastic tubing from the faucet into the adapter
(#15) on the OUTLET (#5) side of the FMU; the tubing should typically
