nuts,
cut and fas-
ten a length
of tubing
(allow
some
slack)
from
the
cold water
pipe,
to the filter head
inlet
compression
adaptor,
FIG.4.
7. Cut
tubing
to the length
needed
to allow
some
slack, fasten
tubing
to the filter outlet
side compres-
sion adaptor,
returning
to the sink cold water
pipe,
as typically
shown
in FIG. 5.
8. Check
to be sure all fittings
are tightened.
9. Before

MATERIALS
AND TOOLS
NEEDED:
You will need
2 sweat
adaptors,
3 / 8" NPT x sweat
(sweat
end to fit
your
sink
cold
water
pipe),
4 sweat
90°elbows,
copper
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 dam-
age the water filter housing.
Be sure to use the fol-
lowing
procedures
to protect
the water filter.
1. CAUTION:
Turn offthe
water supply to the sink
cold pipe. Open the sink cold faucet to relieve pres-
sure in the pipe.
Note: If the sink faucet
is a single
lever,
mixing
type,
also
close the shutoff
valve
on the hot water
side.
2. Use a tubing
cutter
to remove
a section
of the sink
cold
water
pipe
(catch
trapped
water
with
a rag or
towel).
Use sandpaper
or emery-
cloth to thoroughly
dean
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.
Observe
caution
note above.
3. Refer to FIG. 2, page
5, and to the following
draw-
ings.
Make
typical
soldered
assemblies
A and
B as
shown
in FIG. 6. After
they
have
cooled,
apply
Te-
flon tape or pipe joint compound
to the pipe threads.
Then
turn
them
into the filter head
and tighten.
4. Solder
the filter housing,
with assemblies
A and B
installed,
to the cold water
shutoff
valve
