Proper Installation

Please read all instructions, specifications, and precautions before installing and using your water filter system.

Precautions:

For cold water use only.

After prolonged periods of non-use (such as during a vacation), it is recommended that the Filter System be flushed thoroughly. Let water
run for 10 minutes before using.

The QuickTwist™ Filters used with this Filter System have a limited service life. Changes in taste, odor, and/or flow of the water being
filtered indicate that the filters should be replaced.

Before You Begin

n Check under the sink to locate a solid wall surface to mount the Filter System.

NOTE: The Filter System must be mounted in a vertical position.

n Locate the cold water pipe under your sink and observe if it is a flexible hose or a rigid pipe (ex: plastic, metal, copper). Rigid pipes

may require cutting in order to make adequate space to install the Kitchen Faucet Adapter (see Step 2). Also determine if you have
all appropriate tools, fasteners and adapters to fit your plumbing.

n Consult your local plumbing codes and install accordingly.

STEP 1

continued to next page

This filter must be protected
from freezing, which can
cause cracking of the filter
and water leakage.

NOTICE

Because of the product’s limited service life and to prevent costly repairs or possible water damage, we strongly
recommend that the head of the filter be replaced every ten years. If the head of the filter has been in use for
longer than this period, it should be replaced immediately. Date the top of any new head to indicate the next
recommended replacement date.

Safety glasses and a r

espirator are

r

ecommended for this pr

ocess, as it
may produce dust that can cause
severe irritation if it is inhaled or
comes in contact with eyes.

CAUTION

DO NOT DRILL THROUGH AN ALL-PORCELAIN OR CAST IRON SINK. If installing on an all-por

celain

or cast ir

on sink, the faucet must be mounted in a pre-drilled sprayer hole or through the countertop
next to the sink. If the countertop must be drilled, make certain that the area below the drilling
location is free of wiring and pipes. Also, make sure that there is sufficient room to make the proper
connections to the bottom of the faucet mount. DO NOT DRILL THROUGH COUNTER TOPS MORE
THAN 1" IN THICKNESS OR COUNTERTOPS MADE OF TILE, MARBLE, GRANITE OR SIMILAR
SUBSTANCE. Consult with a plumber or the countertop manufacturer for assistance.

STEP 1

Mount the Faucet for Filtered Water (continued)

NOTE: The Faucet for Filtered Water in this package 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 for mounting the 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 to accommodate the Faucet. The Faucet for Filtered Water base should be
positioned securely on a flat surface with adequate space for proper function. Consider convenience and appearance of the faucet
befor

e installation.

IF YOUR SINK DOES NOT HAVE A WATER SPRAYER HOLE, GO TO

1. IF YOUR SINK DOES HAVE A WATER SPRAYER HOLE, GO TO 4.

1 In order to prevent parts and materials from falling down the drain, line the sink with newspaper or a towel.

2 Apply masking tape to the area to be drilled in order to prevent scratching the sink surface or countertop if the drill bit slips

during operation (and to minimize rough edges).

3 Using a pencil, mark the drill hole. Use the 1/4" drill bit to make a pilot hole. Then use the 9/16" or 5/8" drill bit to drill the final

hole. Drill completely through the sink or countertop.

NOTE: Make sure that the Faucet for Filtered Water is assembled. The Faucet for Filtered Water Spout should be inserted into the Faucet
for Filtered Water Body and the retaining nut should be tightened until snug.

4 Guide the Black Rubber Gasket E onto the threaded Faucet for Filtered Water D Stem. Slip the threaded Faucet Stem into the sink

or countertop hole. Make sure the Faucet for Filtered Water sits flat on top of the sink or countertop surface.

5 From underneath the sink, slide the Metal Lock Washer F up the Faucet for Filtered Water Stem. Then screw the plastic Faucet

Stem Nut

G all the way up the Faucet Stem until it is flush with the Metal Lock Washer. Screw until it is slightly snug and check

to make sure the faucet spout is in the proper position. Using fingers, tighten the nut to secure the Faucet for Filtered Water to
the sink.

NOTE: Do not tighten the Faucet for Filtered Water Stem Nut with pliers as it may strip the Faucet Stem threads.

STEP 2

Install the Kitchen Faucet Adapter

NOTE: The Kitchen Faucet Adapter is designed to fit 1/2" NPTF supply threads.

1 Locate the cold water shut-off valve under the sink. Turn off the cold water supply to the sink.

NOTE: If uncertain about which line supplies the cold water, tur

n on the hot water to the faucet. Allow the water to heat up and carefully

feel the pipes under the sink. The pipe that r

emains cool to the touch is 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 1/2" threaded stem on the bottom of the kitchen faucet.

NOTE: If rigid plumbing pipe (metal or plastic) is used, you may need to shorten the pipe using a hacksaw or pipe cutter to accommodate
the Kitchen Faucet Adapter

.

4 Holding the Kitchen Faucet Adapter H in an upright position (see diagram), scr

ew onto the thr

eaded faucet stem.

5 Screw the cold water supply line to the male threads of the Kitchen Faucet Adapter using the nut that was connecting the cold

water line to the kitchen faucet pr

eviously

. For a secur

e fit, tighten the nut using an adjustable wrench.

STEP 3

Mount the System Head

1 Choose an easy-to-access area under the sink to mount the Filter System.

NOTE: To allow adequate space for filter changes, allow a minimum clearance of 4-6" below the QuickTwist™Filters. The Filter System
must be mounted in a vertical position.

NOTE: Mount the Filter System to a solid cabinet wall or wall. If a solid surface is not available, use hollow-wall anchor bolts or toggle
bolts (not included) to secure to the wall.

2 Remove cartridges from system head by turning from right to left.

3 Remove the cap from the top of the System Head A. Using the Built-in Bracket on the back of the System Head, mark the holes for

the Mounting Screws

C on the wall surface.

4 Using a 1/8" drill bit, drill two pilot holes for the Mounting Screws. Insert Mounting Screws into the wall with a Phillips screwdriver,

leaving approximately 3/8" of each Mounting Screw exposed.

5 Hang the System Head on the eyes of the bracket and replace the System Head cap.

STEP 4

Install 1/4" Plastic Tubing for Water Supply Line from
Kitchen Faucet Adapter to System Head Inlet

1 Determine the length of 1/4" Plastic Tubing L that will be necessary to connect the System Head Inlet to the Kitchen Faucet

Adapter

H. Make sure to allow enough Plastic Tubing to prevent kinking in the line.

2 Cut the 1/4" Plastic Tubing squarely on both ends with a utility knife, making sure not to crimp the Plastic Tubing during cutting.

3 Wet one end of the 1/4" Plastic Tubing with water and push it into the Kitchen Faucet Adapter approximately 5/8" until it stops.

NOTE: Do not bend or crimp 1/4" Plastic Tubing when inserting.

4 Wet the other end of the 1/4" Plastic Tubing with water and push it into the System Head Inlet approximately 5/8" until it stops.

NOTE: The 1/4" Plastic T

ubing does not need to be disconnected for general r

outine maintenance and filter replacement. However,
Plastic Tubing may be easily disconnected if necessary. Simply turn off the water supply to the Filter System and press in the grey collar
ar

ound the fitting while pulling the Plastic T

ubing out with the other hand.

Be sure that all electrical appliances and outlets are turned off at the
circuit breaker before working in cabinet area.
