Precautions
WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
CAUTION: This filter must be protected from freezing, which can cause cracking of the filter and water leakage.
CAUTION: 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 your 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.
CAUTION: Turn off water supply to head without cartridge if it must be left unattended for an extended period of time.
NOTE:
• For cold water use only.
• Make certain that installation complies with all state and local laws and regulations.
• The contaminants or other substances removed or reduced by the selected cartridge 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 2-3 minutes before using.
• The filter cartridge used with this system has a limited service life. Changes in taste, odor, color and/or flow of the water being filtered indicate that the cartridge should be replaced.
The IC-750 with 750R or 1000R replacement cartridge is Tested and Certified by
NSF International to NSF/ANSI Standard 42 for the aesthetic reduction of Taste and Odor and Chlorine and Particulate Class I*, Standard 53 for the reduction of
Cysts*, Lead*, Lindane*, Atrazine*, and Turbidity*.
*Applies to 1000R replacement cartridge only.
Installation
• For standard installation on 1/4-inch copper, plastic or flexible hose cold water line.
• Please read all instructions and precautions before installing and using your
IC-750 water dispenser Icemaker Filter
• Numbered diagrams correspond with numbered steps
• Instructions refer to standard installation on existing water line to refrigerator.
Before installation, make sure there is enough slack in existing water line to allow refrigerator to be moved out from the wall.

Installation Continued
1. Mounting the Filter System
(A) Turn off the cold water supply to the refrigerator and dispense the water from the refrigerator door until water flow stops to release the pressure in the pipes before starting installation.
Place a tray or towels under the cold water line to catch the excess water after the pipes are cut.
NOTE: Before starting installation, turn off the icemaker in the refrigerator and store the ice cubes in a clean container in the freezer.
(B) Select location under sink, in basement or near refrigerator where filter is to be mounted.
NOTE: Filter should not be more than 3 feet from the appliance.
NOTE: Allow 1-1/2-inches (33 mm) clearance below housing or 11-inches below filter head to enable filter cartridge changes.
CAUTION: Filter head should be mounted on stud or firm surface. The mounting bracket will support the weight of the filter and help prevent strain on the cold water line.
WARNING: DO NOT screw mounting bracket directly onto the refrigerator.
(C) Filter head should be mounted in vertical position. Use mounting bracket as a template to mark screw locations. Mount filter head in marked location using screws.
CAUTION: Water supply to the refrigerator should have a separate shut off valve installed before filter. If it does not, a separate shutoff should be installed.

2. Cutting or Disconnecting the Tubing
Use a 7 to 8 foot coil (3 coils, approximately 10" diameter) of plastic, copper or flexible hose between the outlet of the filter and the refrigerator.
Determine the length of plastic, copper or flexible hose needed to connect the inlet and outlet of filter.
Using a pipe cutter or hacksaw for copper tubing or utility knife for plastic; cleanly cut tubing or disconnect flexible hose from refrigerator. Leave a minimum of 2-inches (51 mm) of pipe after shut-off valve in case pipe must be re-cut at a later time. Deburr ends of remaining pipe with a file.
3. Connecting the Tubing and Fittings
(A) Connecting the Inlet.
Assemble fittings as shown. Press tubing into fitting until it stops. Hand tighten plus 1 to
1-1/2 turn(s) with a wrench.
(B) Connecting the Outlet.
NOTE: If the water cannot be flushed through an existing water dispenser, install T-Flush valve first and then connect the outlet of the filter the same as step 3A. See Page 1 for a
T-Flush valve diagram.

4. Installing the Cartridge
(A) Hold cartridge from the bottom when installing or changing the cartridge. Use caution not to scrape knuckles on bracket when locking the cartridge into place.
(B) Line up the arrow on the cartridge with unlocked padlock on head. Insert cartridge and turn arrow to locked padlock. See Diagram R4 in Filter Cartridge Replacement on page 3.
5. Putting the Filter into Operation
(A) Turn on water supply to allow filter to fill with water. Check for leaks. If it leaks, see Troubleshooting.
(B) Flush filter for 5 minutes through the water dispenser or if appliance is equipped with only an icemaker, through the T-Valve, and discard water.
(C) Turn on Icemaker.
(D) Check for leaks before leaving installation. If it leaks, see Troubleshooting.
NOTE: A drinking water cartridge may contain carbon fines (very fine black powder). If your icemaker contains black carbon fines, discard ice.

R. Filter Cartridge Replacement
NOTE: It is recommended that the filter be replaced every twelve months, or when you notice a change in taste, odor, or flow of the water being filtered.
(1) Relieve pressure by turning off water supply to the filter and dispense water from water dispenser or T-flush valve until water flow stops.
(2) Place towel under the system to catch any water drips.
(3) (a) Turn arrow from locked to unlocked position and (b) remove cartridge.
(4) (a) Line up arrow with unlocked position on head and insert cartridge. (b) Turn to locked position.
(5) Turn on water and check for leaks. If it leaks, see Troubleshooting.
(6) Flush water through water dispenser or T-Flush valve for 5 minutes to remove carbon fines. Check for leaks before leaving installation.

Troubleshooting
Leaks:
...Between head and cartridge
(1) Turn off the water supply to the filter and dispense water from the refrigerator door or T-Flush valve until water and airflow stops.
(2) Remove cartridge and inspect o-rings to make sure they are in place and clean.
(3) Install cartridge and turn on water supply, if it still leaks, contact Technical
Support at 1-800-645-5426. M-F 7:30 AM - 5 PM CST. Turn off icemaker if filtered water goes to icemaker.
...From fittings
Relieve pressure by turning off water supply to the filter and dispense water through the refrigerator door or T-Flush valve until water and airflow stops. For copper or plastic tubing, loosen the compression nut and pull the tubing from the brass fitting. Inspect to see if the ferrule and insert (plastic only) are properly installed on the tubing. If so, reconnect tubing finger-tight, then tighten nut snug about 1/2 to 1 turn with a wrench. Open the water supply valve. If the leaks persist, or if there are other leaks on the unit, turn off the water supply and icemaker, then call Technical Support at 1-800-645-5426. If the fitting does not leak, turn on the icemaker.
