Install Fittings and Mounting Bracket
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 12
″
of Teflon tape, in a clockwise
direction, to the pipe threads of each fitting.
DO NOT use joint compound on any parts.
Use the bracket as a template to find the
two screw locations. Wood screws are provided. If mounted
onto other surface, use appropriate hardware.
Drill a 3/16
″
hole on each marked screw location (optional),
then drive the two wood screws until about 1/4
″
of thread
is left. Ensure at least one screw is anchored into wall stud.
Assemble a fitting through the mounting bracket hole 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 to
tighten fittings firmly. DO NOT OVERTIGHTEN.

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 electric outlets, please refer to 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 the 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 to install the filter and mounting
bracket. The location should align the filter housing with the
inlet and outlet pipes and should not cause the pipes to bend.
Mark the distance “D” on the pipe. D is about 5
1 ⁄
4
″
for
GXWH04F model and 5 3 ⁄
4
″
for GXWH20F model.
Using a pipe cutter, cut pipe. Sand (file) the cut ends of the
pipe to assure that they are square and smooth.
■ NOTE: Have a bucket and towel available to collect excess water.
