INSTALLATION INSTRUCTIONS
Heavy Duty Water Filtration System—GNWH38F
SAFETY PRECAUTIONS
■ Check with your state and local public works department for
plumbing and sanitation codes. You must follow these guidelines
as you install the Heavy Duty Water Filtration System. Using a
qualified installer is recommended.
■ Be sure the water supply conforms with the
Performance Data
.
If the water supply conditions are unknown, contact your
municipal water company.
WARNING:
Do not use with water that is
microbiologically unsafe or of unknown quality without
adequate disinfection before or after the system.
■ It is highly recommended that a water shut-off valve be placed
directly upstream of your household filter.
■
Check with your local public works department for plumbing codes.
You must follow their guides as you install the Heavy Duty Water
Filtration System.
■
Use the Heavy Duty Water Filtration System on a potable, safe-todrink, home COLD water supply only. The filter cartridge will not
purify water or make unsafe water safe to drink. DO NOT use on
HOT water (100°F max).
■
Protect the Heavy Duty Water Filtration System and piping from
freezing. Water freezing in the system will damage it.
■
Your Heavy Duty Water Filtration System will withstand up to
100 psi water pressure. If your house water supply pressure is
higher than 100 psi during the day (it may reach higher levels
at night), install a pressure reducing valve before the system
is installed.
■ Do not install on
HOT WATER
. The temperature of the water
supply to the Heavy Duty Water Filtration System must be
between the minimum of 40°F and the maximum of 100°F.
See the
Filter Cartridge Life
section.
■
Do not
install the Heavy Duty Water Filtration System using
copper solder fittings. The heat from the soldering process
will damage the unit.
■ If making a soldered copper installation, do all sweat soldering
before connecting pipes to the system. Torch heat will damage
plastic parts.
WARNING:
Discard all unused parts and packaging
material after installation. Small parts remaining after installation
could be a choke hazard.
■
Do not
install filter in an outside location or anywhere it will be
exposed to sunlight.
PROPER INSTALLATION
This Heavy Duty Water Filtration System must be properly installed and located in accordance with the Installation Instructions
before it is used.

Filter Cartridge Replacement
You should change your filter when the water flow is noticeably reduced or at least every 3 months.
Turn off water to filter. Water must be shut off from
an upstream valve.
Press the red pressure release button to release
pressure.
Unscrew the filter canister and discard used filter.
Wash the filter canister with mild soap and water.
Do not
use harsh cleaners or hot water.
Inspect the filter canister O-ring. Make sure it is
lightly lubricated with clean food grade silicone
grease (silicone grease is available through GE
Parts and Service: 1.800.626.2002, part number
WS60X10005). Be sure the o-ring is seated in the
groove. It is recommended that you replace the
O-ring if it is damaged.
Place a new filter cartridge into the canister,
making sure it is centered and completely seated
on the bottom seal.
Reinstall the filter canister to the unit. Use the
canister wrench to tighten the canister. DO NOT
OVERTIGHTEN.
Slowly turn on water to the filter by using the
upstream shut-off valve.
Press the red pressure release button to remove
trapped air.
After installation, flush the cartridge for
10 minutes, wait one hour, then flush again
for 10 minutes before using the water.

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.

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).

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.

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.
