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
Instructions are for installing fittings supplied with the
filter (on some models) or the WHKIT onto 3/4
″
copper
plumbing. If the unit is to be installed on any other type of
tubing (plastic, PVC, galvanized), different hardware must be
purchased. See instructions with additional hardware
purchased, or consult a qualified plumber.
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 an adapter to the inlet and outlet of the head.
Start each fitting by hand to make sure they don’t cross
thread. Use a 1
1
⁄
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:
It 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 Ground Wire
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 housing may have broken this
ground path. To restore connection, install a 12
″
long, 8-gauge
copper wire across the filter, tightly clamped using UL-approved
1/2
″
–1
″
bronze grounding clamps at both ends as shown. Zinc
clamps should not be used on copper plumbing. For
GXWH01C
,
wire and clamps may be purchased separately from your local
hardware store, or are available by visiting our Website at
www.GEAppliances.com, or from Parts and Accessories by calling
800.626.2002 (U.S.)or 800.663.6060 (Canada) – order part
number WHKIT.
Clean copper pipe and ends of wire with emery paper. Bare wire
is recommended. If insulated wire is used, it should be stripped
3/4
″
at each end before cleaning with emery paper.
Attach bronze clamps to copper pipe. Tighten screws.
Attach wire to clamps as shown. Tighten screws.
NOTE:
If your house plumbing is plastic, it would not be used as a
grounding path, and this step should be skipped.

flush for 5 minutes.

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 1
1
⁄
8
″
wrench to hold the adapter in place, use a 1
1
⁄
4
″
wrench to tighten the nut. Repeat process for other fittings.
If necessary, support the water pipe on either side of the filter
unit.
