INSTALLATION STEPS
WATER FILTER HOUSING ON HOUSE MAIN WATER PIPE, TO FILTER ALL HOUSEHOLD WATER
A. USING COMPRESSION FITTINGS, FIG. 1
1. Apply several wraps of Teflon tape to the threads
of both compression fittings.
2. CAREFULLY, turn the compression fittings into the
water filter head inlet and outlet and tighten. Do not
cross-thread and damage the threads. Do not overĆ
tighten and crack the head.
3. Remove the nut and brass ferrule from both comĆ
pression fittings and set aside. Using a tape measure
or ruler, measure the distance ``D'' as shown below.
Mark this dimension below so you do not forget.

4. CAUTION: Turn off the water supply to the
main pipe. Open a high and low faucet, in the water
system, to drain the pipe.
5. On the main water pipe, where you will install the
filter, mark the dimension D. You will remove this secĆ
tion of pipe. Before you begin to cut, double-
check your measurement.
6. Use a tubing cutter to remove the section of pipe.
Remove all burrs and rough edges with the sandpaper
or emery-cloth.
7. Place a nut and brass ferrule (from compression fitĆ
tings) onto both pipe ends.

8. With the inlet side of the water filter facing inĆ
coming water, spread the pipes apart and fit both
pipe ends into the compression fittings. Move a ferrule
and nut up to the fitting. Then, turn on and tighten the
nut. Hold the fitting with 1 wrench while tightening the
nut with the other. Repeat on the other side.

9. Before turning on the water supply, remove the
sump from the filter head and install the filter cartridge
(see page 8).
IMPORTANT: The house cold water pipe is often used
to ground electrical outlets in the home. Grounding
protects you from electrical shock. The water filter
housing may have broken this ground. To restore, buy
and install a #4 copper wire across the filter, tightly
clamped at both ends as shown here.

MATERIALS AND TOOLS NEEDED: You will need 2
sweat adaptors, 3/4" NPT x sweat (sweat end to fit
your main water pipe), lead-free solder and flux,
soldering torch, Teflon tape, sandpaper or
emery-cloth, open end (to fit sweat adaptor) or
adjustable jaw wrench.
CAUTION: Heat created when soldering can damĆ
age the water filter housing. Be sure to use the folĆ
lowing procedures to protect the water filter.
