Cut the pipe and install the fittings

Photo 1: Cut the supply line
Turn off the shutoff valve and disconnect the supply
line. Mark the filter width on the supply line
and cut it out. Tighten the pipe cutter in small
increments to avoid pinching the soft copper tube.
Deburr the cut end with sandpaper or a file (cut plastic
tubing with a utility knife).

Photo 2: Add the fittings
Slip the brass nut and ferrule onto the tubing.
(If you have a plastic water line, insert the brass
reinforcers into the tube ends). Thread the
brass nut onto the fitting until finger tight, and twist it
one full turn with two wrenches (the longer fitting goes
on the supply side).

Photo 3: Snap in the filter
Snap the filter into the supply side. Make sure the
waterflow indicator points toward the fridge.
Support the filter and slowly open the water shutoff
valve until water sprays out of the unhooked end. Hang a
bucket from a screw and flush water through the filter for
approximately five minutes (two to three gallons), and then
snap it into the other fitting.
Install a refrigerator water filter to remove the bad
taste from drinking water and ice cubes. An inexpensive inline
refrigerator water filter reduces chlorine, rust, sediment and odors for
water- and ice-dispensing refrigerators. Filters are
available from home centers and appliance stores.
The filter splices into the standard 1/4-in. copper or
plastic refrigerator water supply line (Photo 1). Locate
the filter as close as possible to the water shutoff valve.
Leave at least 6 in. of clearance between the wall and
refrigerator when installing the filter behind a refrigerator.
Once you install the system, quick-connect fittings
make it easy to change the filter.
Turn off the shutoff valve and disconnect the 1/4-
in. supply line from the valve (hold a bucket under the
valve to catch residual water). Some types of valves
leak. You may have to turn off the main water supply
valve to your home. Cut back the tubing (Photo 1)
and attach the quick-connect fittings (Photo 2). Snap
the filter into the fittings.
Secure the tubing on the fridge side with a 1/4-in.
copper strap and flush the filter to dispense any fine
loose carbon particles (Photo 3). If a leak occurs,
tighten the nuts or fittings. Strap the filter to any nearby
support to take stress off the tubing. Write the
installation date on the filter and replace it every six months with a new one.
