Installation Instructions
Please read all instructions and precautions prior to installation and use.
Precautions
•This filter is for cold water use only.Hot water will damage filter cartridges.
•After prolonged periods of non-use (i.e., vacation), including when first installed, it is recommended the
filter system be flushed thoroughly (let water run for 15 minutes before using).
•These cartridges have a limited service life. Changes in taste, odor, and/or water flow indicate the filter
cartridges should be replaced.
•Before beginning installation, register for a product warranty: https://www.hydranti.com/warranty
Before You Begin
•Install according to local plumbing codes.
•Locate the cold water pipe under your sink. Rigid pipes may require cutting in order to make adequate
space to install the Kitchen Faucet Adapter (C6a / C6b).
•Ensure you have all appropriate fasteners and adapters to fit your plumbing.
•Watch our installation video if you are unsure of what to do at any point during installation:

Step 1
Mount Auxiliary Faucet
Note: This faucet is designed to fit a 9/16” hole. Most standard sinks come with 1-3/8” or 1-1/2” diameter water
sprayer holes that can be used to mount this faucet. If the pre-drilled holes cannot be used or are not in the
desired position, a new hole must be drilled using either a 9/16” or 5/8” drill bit. The faucet should be positioned
securely on a flat surface with adequate space for proper function.
If you need to drill a hole, start from step (1). If you will be using a pre-drilled hole, skip to step (5). If using the
mounting bracket (C3), use 3 screws to mount the bracket to a solid surface, then skip to step (5).
1. Line sink with newspaper or towel to prevent parts and materials from falling down the drain.
2. To help prevent scratching the sink surface or countertop, apply masking tape around the area that will
be drilled.
3. Mark the drill hole using a center punch or
pencil.
4. Make a pilot hole using the 1/4” drill bit. Use
the 9/16” or 5/8” drill bit to drill the final hole.
Drill through the sink or countertop completely
and smooth rough edges with a file.
5. The first rubber gasket fits right into the base
of the faucet. Slide it into place, then guide the
faucet stem into the hole on your
counter/mounting bracket.
6. Under the counter, slide the hard plastic
washer, the small rubber washer, and the
metal gripping washer onto the stem in that
order. Tighten it all with the securing nut.
Step 2
Install the Kitchen Faucet Adapter Valve
Note: This kit includes two adapter valve options: one with 3/8” NPT connections (C6a) and one with 1/2” NPT
connections (C6b). Depending on your undersink configuration, you may need to use a different valve.
Method A (Stop Valve and Sink Supply Line can be Disconnected)
1. Locate the cold water shut-off valve under the sink. Turn off the cold water supply.
2. Turn on the kitchen faucet to release pressure and allow water to completely drain from the line.
3. Disconnect the cold water line from the 3/8” threaded stop valve under sink.
4. Holding the kitchen faucet adapter (C6a) in an upright position, screw onto the stop valve connection.
5. Screw the water supply hose, which leads to the sink, onto the open threaded end of the kitchen faucet
adapter valve. Tighten using an adjustable wrench.
Method B (Stop Valve and Sink Supply Line are Permanently Connected)
1. Locate the cold water shut-off valve under the sink. Turn off the cold water supply.
2. Turn on the kitchen faucet to release pressure and allow water to completely drain from the line.
3. Disconnect the cold water supply hose from the 1/2” threaded stem on the bottom of the kitchen faucet.
4. Holding the kitchen faucet adapter valve (C6b) in an upright position, screw onto the threaded faucet
stem.
5. Using the nut that was previously connecting the cold water line to the kitchen faucet, screw the cold
water supply line to the male threads of the adapter valve. Tighten using an adjustable wrench.

Step 3
Mount the System Head
1. Select an easily accessible area under the sink to mount the filter system.
2. Note: Mount system to a solid cabinet wall or wall. If this is not an option, use toggle bolts or hollow-wall
anchor bolts (not included) to secure the system to the surface.
3. Note: Allow a minimum clearance of 4”-6” below the filter cartridges to allow ample space for cartridge
changes. The filter system must be mounted in a vertical position.
4. Use the back panel as your mounting template, marking the holes for the mounting screws on the wall
surface.
5. Drill two pilot holes for the mounting screws using a 1/8” drill bit. Insert mounting screws into the wall
with a Philips screwdriver, leaving approximately 3/8” of each mounting screw exposed.
6. Position the system head on the eyes of the bracket.
Step 4
Install White Plastic Tubing for Water Supply Line from Kitchen Faucet Adapter Valve to System Head Inlet
1. Determine the length of white tubing (C4) necessary to connect the system head inlet to the kitchen
faucet adapter making sure to allow enough tubing to prevent kinking in the line.
2. Cut the tubing squarely on both ends. Use a tubing cutter to ensure a square cut.
3. Without bending or crimping it, wet one end of the tubing with water and push it into the kitchen faucet
adapter approximately 5/8” until it stops.
4. Wet the other end of the tubing with water and push it into the system head inlet on the left side of the
manifold approximately 5/8” until it stops.
5. Prevent tubing from coming loose from fittings by inserting a clip (C7) as shown in the illustration below.
(Elbow fitting in image not included.)

Step 5
Install Blue Plastic Tubing for Water Supply Line from System Head Outlet to Faucet
1. Determine the length of blue tubing (C5) necessary to connect
the system head outlet to the threaded faucet stem making
sure to allow enough tubing to prevent kinking in the line.
2. Cut the tubing squarely on both ends. Use a tubing cutter to
ensure a square cut.
3. Without bending or crimping the tubing, wet one end of the
tubing with water and push it into the system head outlet (right
side of system head) until it stops. Secure with clip (C7).
4. Gently slide the compression nut along the tubing. Press the
plastic ferrule into the blue tubing fully. The plastic
compression sleeve goes over the tubing, between the
compression nut and faucet stem.
5. Firmly push the tubing into the end of the threaded faucet stem hand-tightening the plastic compression
nut onto the threads. Tighten approximately ½ turn with an adjustable wrench.
Step 6
Install Twist-Lock Filters
Note: When viewing the system from the front, cartridge B1 (RED) should be positioned on the far left, followed
by cartridges B2 (WHITE), and B3 (ORANGE) from right to left. The furthest right cartridge should be the B3
(ORANGE).
1. Hold cartridge under the appropriate part of the head with the label facing left.
2. Lift each cartridge straight up into the system head until the two extended flanges on top of cartridge
are fully engaged into the system head.
3. Turn the cartridge counter-clockwise until it stops.
4. Repeat 1-3 for each cartridge.
Step 7
Test the Filter System for Proper Operation
1. Turn on the cold water shut-off valve under the sink.
2. Turn on the new faucet for filtered water. Allow the water to run for approximately 10 minutes in order
for the filter system to flush out any air and carbon fines (fine black powder from each cartridge).
3. Check for any leaks between the system head assembly and filters, on kitchen faucet adapter
connection, around all fittings and on faucet/tubing connection.
Troubleshooting

Cartridge Replacement
1. Turn off the cold water shut-off valve to the filter system.
2. Place a bucket or pan under the filter system to catch any water drips.
3. Turn each cartridge clockwise until it releases. Gently pull each cartridge down to remove from the
system head. Discard the used cartridges.
4. Hold each cartridge with the label facing to the left slightly. The two nozzles on the top of each cartridge
should be toward the back of the cartridge. See diagram in Step 6.
5. Lift each cartridge straight up into the system head until the two nozzles seat into the ports and the two
extended flanges on top of cartridge are fully engaged into the system head.
6. Turn each cartridge counter-clockwise until it stops.
7. Turn on the cold water shut-off valve and the faucet for filtered water. Check for leaks. If there are
leaks, see Step 7.
8. To flush out any air and carbon fines (fine black powder), flush water through the faucet for filtered
water for approximately 15 minutes.
