STEP-BY-STEP INSTALLATION INSTRUCTIONS (cont.)
Select Location
Select a location for the filter that is:
■
protected from freezing.
■
not exposed to direct sunlight.
It is recommended that a shut-off valve be placed on both sides
of the filter.
Install Fittings
The fittings supplied with the filter are for use with 3⁄4″copper
tubing only. If the unit is to be installed on any other type of
tubing (plastic, PVC, galvanized), separate hardware must
be purchased.
Apply about 6″of Teflon tape, in a clockwise direction,
to the pipe threads (course) of each adapter.
DO NOT
use
joint compound on any parts.
Assemble a fitting to the inlet and outlet of the head. Start
each fitting by hand to make sure they don’t cross thread.
Use a 11⁄8″wrench firmly.
DO NOT OVERTIGHTEN.
About one
to two thread(s) should remain visible.
Cut Water Line
Turn off water supply and open a nearby faucet to drain
water out of pipes.
Remove the nut and brass ferrule from both compression
fittings and set aside. Using a tape measure or ruler,
measure the distance “D” as shown.
■
NOTE:
I
t is recommended that the shut-off valve be placed
before and after the filter as shown in the
Installation
Overview
illustration.
■Select the location for the filter. Mark the distance “D”
on the pipe.
Using a pipe cutter or hacksaw, cut pipe. Sand (file) cut
ends of pipe to assure that they are square and smooth.

Installing the Unit
Align filter assembly with pipe ends making certain that
the
incoming
water supply is going into the filter opening
marked “IN”. It may be necessary to spread the pipe ends
apart to install filter assembly.
Using a
11⁄8″
wrench to hold the adapter in place, use a 11⁄4
″
wrench to tighten the nut. Repeat process for other fittings.
If necessary, support the water pipe on either side of the
filter unit.
Installing the Ground Wire
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 copper, buy and install a #6 copper wire
across the filter, tightly clamped at both ends as shown here.
Install clamps to copper pipe on both sides of the unit
(as shown).
Securely attach each end of the grounding wire to the pipe
with the clamps.

Check entire system for leaks.
If leaking, shut off water pressure and tighten or reseal
fittings.
Open any downstream faucet and allow filter system to
flush for 5 minutes.
