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.

Countertop Kit Components
Included with the Countertop Kit are the following key components:
1. Acrylic Base: Used to hold the CB-As upright on the countertop. The
CB-As is placed on the acrylic base with the ports and tubing facing
down, so that the tubing can feed through the openings at the side of
the acrylic base.
2. Diverter valve: Used to connect the dual-hose from the CB-As to the
existing sink faucet. The diverter valve comes pre-attached to the dual-
hose, and allows selection of ltered or unltered water from the faucet.
3. Dual-hose: Used to connect the diverter valve to the CB-As.

Connect the Diverter Valve
1. Remove the aerator or screen (if present) from the end of the faucet. If
facing the open end of the spout, rotate the aerator counter-clockwise
to loosen and remove.
2. Attach the diverter valve directly to the faucet spout. If the threads
of the diverter valve do not match the threads of the faucet, use one
of the included faucet adapters to connect the diverter valve and
faucet. If facing the open end of the spout, rotate the diverter valve
and/or adapter clockwise to tighten.
NOTE: When using a faucet adapter, the rubber washer in the adapter
always faces up toward the faucet.
a. If Your Faucet Has an Outside Thread (male connector):
For many faucets with an outside thread, the diverter valve can
attach directly to the faucet. If the diverter valve is too small to
attach to the faucet, attach the inside thread (female connector)
adapter, part# MC106, to the faucet, and then attach the diverter
valve to the adapter.
b. If Your Faucet Has an Inside Thread (female connector):
The diverter valve cannot directly connect to a faucet with a female
connector. Attach one of the outside thread (male connector)
adapters, part# MC107 or part# MC108, to the faucet, and then
attach the diverter valve to the adapter. MC107 is designed to t
larger faucets, and MC108 is designed to t smaller faucets.

c. If Your Faucet Requires More Room for the Diverter Valve Connection:
Some faucets, particularly sprayer hose faucets, require additional
room for the diverter valve connection. If this applies, attach the
long adapter, part# MC257, to the opening of the faucet spout/
sprayer, and then attach the diverter valve to the adapter. The CB-
As may need to be repositioned on the sink to allow enough room
for sprayer faucet use.
d. If the Adapters Do Not Fit Your Faucet:
Although the adapters included with your CB-As allow connections
with many standard faucets, they do not cover every type of
available faucet connection. If none of the adapters allow the
diverter valve to connect to your faucet, please contact your
Dealer, to request part# MC105, part# MC109, or part# MC719 as
possible adapter solutions.
NOTE: When connected properly, the hose from the diverter valve
should lead toward the back of the faucet and sink.
3. The diverter valve features a bypass lever with a button on the left and
right sides of the diverter valve. Press the left button to bypass the DWS
and select the unltered water spout (larger opening). Turn on your
faucet to let unltered water ow out of the diverter valve and to make
sure that the diverter valve is properly connected.
4. Turn off the faucet.
5. Proceed to section Connect the Tubing to the Housing (Pg 14).
19
The CB-As can be used inline for connection to refrigerators, water coolers,
or ice makers, so that all of the water from the cold water outlet or faucet is
ltered. CB Tech recommends that a professional plumber install the system
for inline use.
Inline Installation

1. Using a paper towel or cloth, dry off all connections and the system housing.
2. Make sure that all connections are tightly secured.
3. Remove any air and loose carbon from the system.
a. On a below-sink conguration:
i. Turn the water supply back on; rotate both the Adapta Valve
shutoff valve and either the water supply Angle Stop Valve or
water shutoff valve counter-clockwise to engage the ow of
water through the pipes.
ii. Turn the handle on the CB-As faucet to start the ow of ltered
water.
iii. Allow water to ow through the DWS and the faucet for 30
minutes. This purges any air and loose carbon from the system.
iv. Adjust the Angle Stop Valve or water shutoff valve so that the
water ow to the drinking water faucet does not exceed the
ow rate.
NOTE: It takes approximately 15 seconds to ll a quart at 1.0
gallons per minute ow rate.
b. On a countertop conguration:
i. Press the right button on the diverter valve to select the ltered
water spout. The water will ow through the DWS and emerge
from the smaller opening on the diverter valve.
ii. Allow water to ow through the DWS and ltered water spout
for 30 minutes. This purges any air and loose carbon from the
system.
iii. Press the left button to select the unltered water spout, and
then turn off the faucet.
4. Check all connections to make sure that there are no leaks.
5. Congratulations! Your system is now ready for use!
