2. Cutting or Disconnecting the Tubing
Use a 7 to 8-foot coil (3 coils, approximately 10-inch 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. T-flush valve can also be installed
after copper or tubing is connected to outlet. Connect
outlet of filter the same as Step 3A.
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 4.
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 15 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.
NOTE: Initially, filtered water may appear cloudy. If cloudiness in
a glass of water disappears from the bottom, air within the
water will disappear within a few weeks after installation.
INSTALLATION IS NOW COMPLETE.
R. CARTRIDGE REPLACEMENT
It is recommended that the filter be replaced every six 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 refrigerator door 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.
