Step 1 –Faucet Install(Standard Non-Air-Gap Faucet)

Be sure to turn off the cold water line before you start.

1. Most sinks have an extra hole for the mounting of additional faucets, sprayers or

soap dispensers. If your sink does not already have an additional hole, you will

want to drill a ½” hole for the drinking faucet.

2. Once the hole is prepared, assemble the parts of the faucet that belong above

the sink. First is the faucet spout. Some faucet spouts have threads; most do

not. It is not necessary to tighten the faucet spout, and is preferable to let it move

freely so you can move it out of the way when you wish. Insert the faucet stem

into the hole in the faucet body. No plumber's putty is needed since the small

round rubber washers provide

the seal.

3. The large chrome base plate

goes underneath the faucet

body, then the large black rubber

washer.

4. From under the sink, slide the

thick black washer on first

followed by the lock washer.

Tighten firmly into place once the

faucet is properly aligned.

Step 2 –Install Water Supply Connector

1. Turn off the cold water line under the sink. Open the kitchen faucet to release

any pressure and make sure the water has stopped before proceeding. Get a

towel or bucket to catch any water drips.

2. Disconnect the water supply line

from the cold water connection

underneath the sink. Wrap the male

end of the water supply connector

with 3-4 wraps of Teflon tape to

ensure a proper seal. Screw the

female side of the feed water

adapter onto the cold water line

first, and then screw on the cold

water line to the male end of the

feed water adapter. Ensure a

proper seal, but do not over-tighten.

3. When the handle of the feed water

adapter is turned perpendicular to

the water line, this is the "OFF"

position. When in line with the

water line, the connector is “ON”.

Step 3 –Install Filters

1. Make sure the O-ring is seated inside the

groove on top of the filter housing. A light

amount of food-grade silicon jelly may be

used to help the O-ring seal better, but is

not required.

2. The filter cartridges are preserved in shrink

wrap. Note the direction sign on the sticker

before removing the wrap.

3. When placing the filter cartridge into its

housing, make sure it is centered and the

knob protruding from the bottom of the

housing fits in the central hole of the filter.

4. Screw the housing, with filters attached, onto the housing. The cap also has a

center knob which should be inserted into the center hole of the filter cartridge.

Twist the housing on in a clockwise direction by hand, and then use the housing

wrench to tighten it another 1/4 –1/2 of a turn. Do not over-tighten. This can

cause leaks and make it difficult to unscrew the housing when replacing

filters. Follow steps 1-4 to install the rest of filters.

Step 4 –Fitting and Tube Connections

1. Fittings: Wrap the male end of the fittings with 4-5 wraps of Teflon tape to

ensure a proper seal, and then screw them into each side of the system. Do not

over-tighten.

2. Supply Tube: Insert the tube into the fitting until you reach the ⅝” mark on the

tube. Pop the blue lock clip back on the fitting. This will lock the tube in place and

prevent it from moving.

3. Faucet Tube: Slide the brass nut and tube collar onto the tube.Fully insert the

tube insert into the end of the tube. Slide the tube collar towards the tube insert

until it stops. Insert the tube into the tapered, open end of the threaded metal

inlet. Screw on the brass nut and tighten it up. The brass nut compresses the

plastic tube collar onto the tapered metal surface and creates a water seal

between them while the tube insert stiffens the tubing.

Installation Tips

How to use the Quick-Connect fittings

To connect:

1. Check and cut the tubing end squarely and cleanly with utility knife or scissors.

2. Make a ⅝” mark at the end of the tube so you will be able to confirm when the

tube is inserted fully into the fitting.

3. Remove the blue lock clip from the fitting

with your nail. If the lock sleeve pops out

of the fitting when doing this, simply pop it

back in.

4. Insert the tube into the fitting until you

reach the ⅝” mark on the tube. You will

feel resistance when the tube reaches the

small rubber O-ring inside the fitting. You

will need to wiggle the tube and apply

additional pressure to get it past this O-

ring and create the seal. If the tube is

not ⅝” into the fitting and past the O-

ring, no seal will be created and

leaking will occur.

5. Once the tube is fully inserted into the fitting, pop the blue lock clip back on the

fitting. This will lock the tube in place and prevent it from moving.

To disconnect:

1. Remove the blue lock clip from the fitting.

2. With the blue lock clip removed, use your thumb and

index finger to hold down the lock sleeve. This will

release the metal teeth holding the tube in place.

While holding the lock sleeve down with that hand,

use your other hand to remove the tube from the

fitting.

Step 5–System Start-Up

When everything is in place, open the

drinking faucet and lock it open. Slowly

open the water supply connector and

allow water to flow into the unit,

eventually exiting through the faucet.

Check for leaks.

Allow the faucet to remain open to

rinse the unit for at least five minutes. It

is normal to see residual carbon and

fine air bubbles in the water when

flushing the system for the first time. If

the faucet drips a bit when closed, this

is also normal for the first couple of

days and is the result of pressure from

trapped air. This too shall pass.

*Check for leaks daily for the first week and occasionally thereafter.

Step 6 –How to Change Filters

1. Shut off the cold water supply valve. Place a bucket or towel under the system to

catch any water spills.

2. If there is enough room under the sink and the filter system is hung on the wall,

you can twist the filter housing off without removing the system from the wall.

Otherwise, you will need

to pull the system out, lay

it down, and remove the

housing at that point. Be

careful with the tubing

connections when

removing the system.

3. Twist off the filter

housings in a counter

clockwise direction using

the filter housing wrench.

4. Refer to installation Step

3 to install the new

vertical filter cartridges,

and tighten the filter

housings back on.

Remember not to over-tighten them or they will be hard to unscrew next time.
