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.
It is recommended that a mounting bracket be used.
Install Mounting Bracket and Fittings
Instructions are for installing fittings supplied with the filter system or
similar fittings onto copper plumbing. If the unit is to be installed on
any other type of tubing (plastic, PVC, galvanized), consult a
qualified plumber for additional hardware.
Attach heavy duty mounting bracket to head assembly
with four hex-head screws as shown in illustration.
Failure to use the bracket may result in a leak over time.
The bracket can be used as a template for marking the
location of the mounting screws.
Apply 4 or 5 wraps of white sealing tape, in a
clockwise direction, to the pipe threads of each
fitting. DO NOT use joint compound on any parts
connecting to filter system.
Assemble fitting to the inlet and outlet of the head. Start each
fitting by hand to make sure they don’t cross thread. Use an
adjustable wrench to tighten fittings. DO NOT OVERTIGHTEN.
About 1–2 thread(s) should remain visible.
Use four hex washer-head screws to mount bracket to the wall firmly.
Use proper anchors on wall. Anchors are NOT included. 4

Cut Water Line
WARNING:
A copper or galvanized cold water pipe may
be used to ground electrical outlets in the home. Failure to maintain this
ground path may result in an electric shock hazard. If the cold water
pipe is used to ground electrical outlets, please refer to the Installing the
Ground Wire section before cutting the pipe.
Turn off the water supply and open a nearby faucet to drain the
water out of pipes.
Using a tape measure or ruler, measure the distance “D” as shown.
■ NOTE: It is recommended that the shut-off valve be placed before and
after the filter as shown in the Installation Overview illustration.
■ Select a secure location surface to install filter and mounting bracket.
The location should align the filter system with inlet and outlet pipe
and should not cause the pipes to bend or damage. Mark the distance
“D” on the pipe. D is about 7
3 ⁄ 4
″
.
Using a pipe cutter, cut pipe. Sand (file) cut ends of pipe to assure
that they are square and smooth.
■ NOTE: Have a bucket and towel available to collect excess water.

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 two adjustable wrenches, hold incoming fitting securely with
one wrench and tighten nut with second wrench. Repeat this
procedure for outgoing fitting.
If mounting bracket is not used, support the water pipe on either
side of the filter unit.
Install a filter and tighten canister to seal (see filter cartridge
replacement section). 4

Final Check
Install filter, if not already done (see Filter Cartridge Replacement
Section).
Slowly turn on water supply.
Check entire system for leaks.
If leaking from fittings, shut off water flow and tighten or reseal
fittings. If leaking from the canister, tighten canister with a wrench.
After installation, flush the cartridge for 10 minutes, wait one hour,
then flush again for 10 minutes before using the water. 5

Installing the Ground Wire
NOTE: If your house plumbing is plastic, it would not be used as a
grounding path, and this step should be skipped.
IMPORTANT: A copper or galvanized house cold water pipe is often used
to ground electrical outlets in the home. Grounding protects you from
electrical shock. The water filter system may have broken this ground
path. To restore connection, install the included 6-gauge copper wire
across the filter, tightly clamped using the included UL approved
1/2
″
–1
″
bronze grounding clamps at both ends as shown.
Clean copper pipe and ends of wire with emery paper.
Attach bronze clamps to pipe. Tighten screws.
Attach wire to clamps as
shown. Tighten screws firmly
to the stripped end of the
copper wire. 3
