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.
