INSTALLATION STEPS (cont.)
WATER FILTER HOUSING ON HOUSE MAIN WATER PIPE, TO FILTER ALL HOUSEHOLD WATER
2. On the main water pipe where you will install the
filter use a tubing cutter to remove a section of pipe
about 12" long. Use sandpaper or emery-cloth to
thoroughly clean and remove all burrs and rough
edges from both pipe ends.
Note: When soldering, use lead-free solder and flux
only. Be sure pipe and fittings are properly cleaned.
3. Solder a sweat adaptor onto one of the pipe ends.
4. Place, but do not solder, a straight connector onto
the other pipe end.

5. Remove the sump from the filter head and set the
sump aside.
6. After it cools, apply several wraps of Teflon tape to
the threads on the sweat adaptor fitting.
7. Carefully turn the filter head INLET (if water flow
is from the left) onto the sweat adaptor fitting. If wa­
ter flow is from the right turn the outlet side of the
head onto the fitting. Do not cross-thread or over­
tighten and crack the filter head.

8. Turn a sweat adaptor fitting into the other side of
the filter head and hand tighten only. Using a tape
measure or ruler measure the distance "D" as shown
below. Mark this same dimension on a length of cop­
per pipe. Cut the length of pipe.

9. Remove the sweat adaptor fitting from the filter
head and solder to the cut length of pipe.
10. After it cools, apply several wraps of Teflon tape
to the threads on the sweat adaptor fitting. Apply
flux and place the pipe end of the soldered assembly
into the straight connector. Then turn the adaptor
end into the filter head and tighten.
11 . Solder both sides of the straight connector.
12. Before replacing the sump and turning on the
water supply install the filter cartridge (see page 8).
Note: Read the grounding information on page 6,
and comply with the instructions if required to main­
tain continuity.

THREADED PIPE AND FITTINGS, FIG. 3
MATERIALS AND TOOLS NEEDED: For threaded
pipe installation you will need a pipe threading tool,
pipe wrenches, pipe joint compound, union fittings
and pipe nipples. Connect the filter housing as typi­
cally shown in FIG. 3, page 4. Observe the follow­
ing:
■ Use pipe joint compound on all external threads.
■ Do not turn pipe or fittings too tightly into the filter
head or you may break it.
■ It is important to have some linear movement in
the house main water pipe. This will allow you to
tighten union fittings without damaging the filter
head if pipe lengths are not exact.
Note: Read the grounding information on page 5,
and comply with the instructions if required to main­
tain continuity.
