Timer battery installation and change
Insert coin or screwdriver into the slot between
timer cap and base. Gently pry them open and
separate timer base from cap. Install or change
2 new AAA 1.5 volt batteries. After you have
the batteries in place, line up the base and cap
and snap them back together.
It is recommended to change the batteries at
least every 2 filter changes, or when the blue
LED light seems dim.
Do not mix old and new batteries. Do not mix
alkaline, standard (carbon-zinc) or rechargeable
(ni-cad, ni-mh, etc.) batteries.
Installation of timer
Hold the timer body in the center and gently
push the timer to its seat at the top of the head
or attach it in a remote location for easy viewing.
Timer reset and application
After new batteries are installed or filter is
changed, push and hold the blue timer reset
button (hold the reset button for approximately
5 seconds). Release the reset button after the
light stops flashing. The timer has been reset.
The light will flash again in 90 days to remind
you that it is time to change the filter.
STEP-BY-STEP INSTALLATION INSTRUCTIONS (cont.)
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 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,
6-gauge copper wire across the filter, and tightly clamp using
UL-approved 1/2″–1″ bronze grounding clamps at both ends as
shown. Zinc clamps should not be used on copper plumbing.
For GXWH04F, wire and clamps may be purchased separately
from your local hardware store, or are available by visiting our
Website at ge.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.

with a wrench.
