INSTALLATION STEPS
6 . Using fentiles and compression nuts, cut and fasten
a length of tubing (allow some slack) from the cold
water pipe, to the filter head inlet compression adap­
tor, FIG5-
7. Cutting to the length needed to allow some slack,
fasten tubing to the filter outlet side compression
adaptor, returning to the sink cold water pipe, as typi­
cally shown in FIG, 6,
8. Check to be sure all fittings are tightened
9. Before turning on the water supply, r emove the
sump from the filter head and install die filter cartridge
(see page 7).
FIG. 6
TO SINK
COLD FAUCET
B. SOLDERED COPPER FITTINGS, FIG. 2
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. CAUnON: Turn off the 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
clean, and remove all burrs and rough edges, from
both pipe ends
Note: When soldering, use lead-free solder and Bux
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, 7. After they have cooled, apply Teflon
tape or pipe joint compound to the pipe threads.
Then, tur n tliem into the filter head and tighten,
4. Solder the filter housing, with assemblies A and B
installed, to the cold water shutoff valve C. Wrap a wet
rag around assembly A to reduce heat transfer through
the pipe, and into the head
5- Protect the filter housing from soldering heat, as
you did above, and complete the connections (D) to
the faucet cold water pipe,
6. Before turuing on the water supply, remove the
sump from the filter head and install die filter cartridge
