Step B - ake Tubing Connections
OTE: Remove protective foam plugs before connecting tubes (See Fig. 4). Discard foam plugs.
1. Locate the piece of supplied 3/8" tubing not used previously. Route it between the union connector
and the filter system outlet (See Figures 2 & 3). Allowing some slack, measure and cut to length. Cut
the ends of the tubing square.
2. Insert tubing all the way into the union connector and filter system outlet. Pull on the tubing to be
sure that it's held firmly in the fittings.
3. Repeat steps 1 and 2 to connect the tube installed on the cold water shutoff to the filter system inlet.
Tubing Connection (all push-in fitting locations):
This system includes push-in fittings for quick tubing connections. When working with the fittings, do the
following.
continued on the next page
Step A - Install Water Supply Fittings
Check and comply with local plumbing codes as you plan, then install the fittings to connect the
undersink filter into the sink’s cold water supply line. Fittings (9/16-24 thread) and 3/8” O.D. tubing are
included to provide connections to and from the undersink filter’s inlet and outlet. A typical connection
using the included water supply fittings is shown in Figure 3.
1. Close the sink’s water shut off valve(s), or another shut off valve upstream from where you will
install the filter, and open faucets to relieve pressure from the sink’s cold water supply line.
2. Locate the line connecting the cold water shutoff to the sink faucet. Typically this line will be a flexible
hose. Disconnect the nut that connects this line to the cold water shutoff. Use a bucket to catch water
that drains from this line.
3. Locate one piece of the supplied 3/8” tubing, plus the supplied compression nut, ferrule and tubing
insert (See Fig. 3). Assemble the parts onto the tube, as shown in Figure 3, and thread the compres-
sion nut onto the cold water shutoff. Tighten to provide a leak-tight connection.
4. Locate the water supply adaptor (supplied) and, using thread sealing tape, install it into the nut on the
supply line which you disconnected in Step 2. Refer to Figure 3.
5. Press the stem of the water supply adaptor into one end of the supplied union connector (See Figure
3). Be sure to push the stem all the way in.

If needed cut the tubing again.
3. Push tubing through the collet and all the way into fitting. Full engagement is 3/4" length of tube into
the fitting.

Step D - Turn On Water, Check for Leaks and Rinse Carbon Fines
1. Open the shutoff valve(s) that you closed at the beginning of this installation.
2. Open the filtered water faucet to purge air from the system. When the water runs smooth, with no
bubbles or spurting, close faucet and check installation for leaks.
3. Open the filtered water faucet and let water run for 10 minutes to rinse out carbon fines.
Step C - Install the Filter Cartridge
1. Remove the small plastic shipping cap from the open end of the filter cartridge.
2. Install the cartridge onto the water filter head assembly, as shown in Figure 6. Turn cartridge to the
right to tighten.

Filter Cartridge Life
Taste and Odor Cartridges: A taste and odor cartridge contains activated carbon. When new, open the
filtered water faucet and allow fine, carbon particles to purge from the cartridge. Flush for 10 minutes. It
is recommended to replace filter cartridge every six months of use. There are several variables that
determine how long a cartridge will last. These include:
1. How much water you use, and
2. How much sediment, taste and/or odor, or other unwanted substance, is in the water.
Use the following information as a guide. However, no matter which type of cartridge you are using, you
will know it is time to replace them when you first notice the return of the unwanted sediment, taste
and/or odor in your water, or when the flow diminishes or stops.
Whirlpool®Undersink Full Flow Water Filtration System model WHEUFF with replacement element
WHEURF conforms to NSF/ANSI 42 and 53 for the specific performance claims as verified and substan-
tiated by test data. The rated capacity for this system is 2000 gallons (7570 liters) at a rated service flow
of 2.0 gallons per minute (7.57 liters per minute).
Filter Cartridge Replacement
OTE: There is no need to shut off the water supply when replacing the filter cartridge.
1. Turn filter cartridge to the left to remove cartridge from the filter head.
2. Dispose of the cartridge in a proper manner.
3. Install new cartridge. Turn cartridge to the right to re-attach to the filter head.
Taste and Odor Cartridges: Taste and odor cartridges contain activated carbon, a black powder.
When new, open the filtered water faucet and allow fine, carbon particles to purge from the cartridge.
Flush for 10 minutes.
