Precautions

WARNING: Do not use with water that is microbiologically unsafe or of

unknown quality without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts.

CAUTION: Filter must be protected against freezing, which can cause cracking of

the filter and water leakage.

NOTE:

• Filter cartridge life varies depending on filter type, usage, and water conditions.

• For cold water use only.

• Make certain that installation complies with all state and local laws and regulations.

• The replacement filter cartridge used with this system has a limited service life. Changes in taste, odor, or flow of the water being filtered indicate that the cartridge should be replaced.

• The contaminants or other substances removed or reduced by these systems are not necessarily in your water. Ask your local water municipality for a copy of their water analysis, or have your private well tested by a reputable water testing lab.

• After prolonged periods of non-use (such as during a vacation) it is recommended that the system be flushed thoroughly. Let water run for 5–6 minutes before using.

The CT-2 is Tested and Certified by NSF International against NSF/ANSI Standards 42 for the aesthetic reduction of Taste and Odor, Chlorine Particulate Class I. Standard 53 - Asbestos, Cyst, Lead, Mercury and Turbidity Reduction.

Installation

• Please read all instructions and precautions before installing and using your Culligan Countertop Water Filter.

• Numbered diagrams correspond with numbered steps.

1. Remove aerator from faucet on which filter will be installed (Fig. 1).

2. Determine the type of threads on your faucet: External threads: No adapters should be needed. Proceed to Step 3. Internal threads: Through trial and error, select the proper adapter and

washer (Fig. 2) and screw into faucet. Tighten manually.

NOTE: Adapters are included which will fit most faucets. To create a tight seal, you may need to use the gasket from your faucet's aerator in addition to the washers included with the adapters. If the adapters do not fit, consult your local plumbing or hardware supplier for assistance in obtaining the correct thread adapter.

3. Screw the diverter valve onto the faucet, turning swivel collar to tighten (Fig.

3). Make certain that gasket (already installed in diverter valve) is positioned securely between the diverter valve and the faucet (or adapter). Rotate diverter valve stem to desired position. Swivel collar may need to be retightened. Place assembly conveniently next to sink.

Operation

4. Turn on water and pull valve stem (Fig. 5). This causes the water to flow through the filter before exiting the faucet. To stop water flow to filter, either push in the valve stem or turn water off.

NOTE:

• A drinking water cartridge may contain carbon fines (very fine black powder). After installation, flush the cartridge for 5 minutes to remove the fines before using the water.

• It is recommended that you run the tap at least 20 seconds prior to using water for drinking or cooking purposes.

• During initial use, your water may appear cloudy. This cloudiness is caused by air that has been trapped in the cartridge. If you let the water sit for 5 minutes in a glass, you will notice the cloudiness disappear from the bottom up. This phenomenon is not harmful and will clear up within a few weeks as the remaining air is flushed from the cartridge.

Filter Cartridge Replacement

A. Turn off faucet. Holding filter over the sink, turn it upside down and unscrew the top of the housing

from the base (Fig. A). Empty excess water into sink. Set top of filter housing aside.

B. Pull filter cartridge to remove from the base (Fig. B). Discard used cartridge. Wipe top and base of

filter housing clean with warm water, mild dish soap and a soft cloth. Do not use harsh detergents, abrasive cleaners, or wire brushes, as they may damage the system.

C. Set base of filter on counter. Insert filter cartridge securely into filter base as shown in Figure C. NOTE: Make sure both black O-rings are present at bottom of filter cartridge. D. Screw top of filter housing onto base by hand and turn until you hit a hard stop. The Culligan logo

on the front of the housing should line up directly opposite the tubing.

E. Follow instruction #5 under Operation on page 2.

Troubleshooting

Leaks between Base and Housing

1. Turn off faucet and unscrew base of housing.

2. Check to make sure gasket is clean and undamaged. Replace if necessary.

3. Reinsert cartridge securely into base and screw top of housing back onto base until you hit a hard stop. The Culligan logo on the front of the housing should face directly opposite the tubing on the base of the housing. If leaks persist, call Technical Support at: 1-800-645-5426.

Valve Stem Will Not Release

1. Unscrew diverter valve from faucet.

2. Soak in vinegar up to one hour to remove scale build-up, periodically pulling and releasing valve stem.

Decreased Flow or Return of Bad Taste/Odor

Replace filter cartridge.
