CUW4 Installation

CAUTION: Improperly installed systems could result in water damage

due to leaks or flooding. If you are not familiar with standard sink

plumbing systems and the proper use of common hand and power tools

or have any difficulty with the installation of this system, please consult

a licensed professional, such as a contractor or plumber.

Preparation

Location:

This water filter can be installed anywhere that has a proper cold-water

supply, such as under the kitchen sink, behind the refrigerator, next to

your aquarium, inside your RV, etc.

Tools needed:

1. 3/8 inch and ¼ inch wrenches or adjustable wrench

2. Phillips and flathead screwdrivers

3. A pair of scissors or a utility knife

4. Bucket and towel to catch water drips

5. Variable speed power drill with ½ inch steel or marble hole saw bit

if a hole needs to be drilled in the counter

Installing the Feed Water Adapter

1. Turn off your Inlet Water Valve (COLD), and open the kitchen

faucet to release water pressure.

2. With a towel or bucket underneath, disconnect the faucet’s water

hose from the Inlet Water Valve using the 3/8-inch wrench, and

install the Feed Water Adapter (AFW) between them. Make sure

the rubber washers are still in place. It is usually not necessary to

use Teflon tape here. Tighten the hex nut by hand and use the

wrench for the final ¼ - ½ turn. Do not over tighten.
