IMPORTANT INSTALLATION RECOMMENDATIONS

Read entire manual. Failure to follow all guides and rules could cause personal injury or property damage.

• BE SURE TO FOLLOW ALL APPLICABLE STATE AND LOCAL CODES.

• Use a qualified installer.

• Do not install the Reverse Osmosis system outside or in extreme hot or cold temperatures. DO NOT INSTALL ON HOT WATER.

• Recommended installation is under the sink. However, the unit can be installed in a remote location, up to 30 feet away from the sink.

Additional installation materials may be required.

• If unit is installed in basement, with faucet on 1st floor, some capacity loss may be experienced. RVTNK1 can be purchased to provide
additional capacity.

• If Reverse Osmosis system is connected to a refrigerator icemaker, a special icemaker connection kit is required (RVKIT). Do not use
copper tubing for the connection between the Reverse Osmosis system and the refrigerator.

• Be sure the water supply conforms to the specifications on page 2. If water supply conditions are unknown, contact your municipal
water company or your local health department for a list of contaminants in your area and a list of laboratories certified by your state
to analyze drinking water.

WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before

or after the system. Systems certified for cyst reduction may be used on disinfected water that may contain filterable cysts. This
Reverse Osmosis system contains a replaceable treatment membrane cartridge critical for effective reduction of Total Dissolved
Solids. The water should be tested periodically to verify that the system is performing satisfactorily. This system is acceptable for
treatment of influent concentrations of no more than 27 mg/L nitrate and 3 mg/L nitrite in combination measured as N and is
certified for nitrate/nitrite reduction only for water supplies with a pressure of 280kPa (40 psig) or greater. Small parts remaining
after the installation could be a choke hazard. Discard safely.

THINGS TO CHECK BEFORE BEGINNING INSTALLATION

FEED WATER—The water supply to the undercounter Reverse Osmosis system must

have the qualities listed in the specifications (see page 2). Municipal water supplies most
often will have these qualities. Well water may need conditioning—have the water tested
by a water analysis laboratory and get their recommendations for treatment.

CAUTION: For water with hardness greater than 10 grains (at 6.9 pH), the use
of

a softener is recommended. Failure to install a softener will reduce the life of

the Reverse

Osmosis membrane. See Fig. 1A for additional information on the

possible need for a softener.

DRAIN POINT*—A suitable drain point and air gap (check your local codes) are
needed for reject water from the Reverse Osmosis membrane cartridge.

RO FAUCET—The RO product water faucet installs on the sink or on the countertop
next to the sink. Often, it is installed in an existing sink spray attachment hole. Space is
required underneath for tubing to and from the faucet, and for securing the faucet in
place. All faucet connections and installation procedures are done on or above the sink
or countertop. Refer to

Electronic Faucet Installation

section.

BASEMENT INSTALLATION—If installing in a basement, leave enough tubing in
place during installation to be able to move unit to floor for ease of servicing and making
filter/membrane changes.

STEP-BY-STEP INSTALLATION INSTRUCTIONS

FEED WATER SUPPLY

Check and comply with local plumbing codes as you plan, then install a cold feed water supply fitting. For new home installation using

standard plumbing fittings, see Fig. 2A below. A typical installation for existing homes using the saddle valve is shown in Fig. 2B below.

A. PREFERRED INSTALLATION

1. Turn off the cold water supply.

2. Complying with plumbing codes, install a fitting on the cold

water pipe to adapt 1 ⁄4 ″OD tubing. A typical connection is

shown in Fig. 2A (parts not included). Make sure a water
supply valve is used.

B. OPTIONAL INSTALLATION

Where codes permit

NOTE: Codes in the state of Massachusetts require installation
by a licensed plumber and do not permit the use of the saddle
valve. For installation, use plumbing code 248-CMR of the
Commonwealth of Massachusetts.

1. Turn off the cold water supply and attach saddle valve as

shown in Fig. 2B.

DANGER: To protect yourself from serious injury or
fatal shock, use a battery powered hand drill only to make
the hole. Do not use an electric drill.

2. Close the water supply valve by turning the handle clockwise.

3. Open the main water supply valve and several house faucets

to purge air from the system. Close faucets when water runs
smoothly.

FILTRATION DRAIN CONNECTION INSTALLATIONS

Check and comply with all state and local plumbing codes as you plan.

CAUTION: The options detailed below are the ONLY approved installation
configurations. Do not use any drain saddle device.

NOTE: Failure to follow these Installation Instructions will void the Warranty, and the

Installer will be responsible for any service, repair, or damages caused thereby.

PREFERRED INSTALLATION OPTIONS

(Options A, B and C)

OPTION A.
BASEMENT ACCESS INSTALLATION (FIG. 3A)

Route the drain line DIRECTLY from the Reverse Osmosis system to a standpipe in
the basement, bypassing the air gap provided in the faucet. The drain line may also
be routed in the basement to a floor drain or washtub, provided that the air gap in the
basement is maintained. Avoid dips, loops or low spots in the drain line. The basement
air gap and drain installation configuration must conform to all local codes. Special air
gap fittings are available to connect the drain line to the top of the standpipe.

OPTION B.
SEPARATE VENT INSTALLATION—2 P-TRAP (DRY-VENTED) (FIG. 3B)

Install a separate dry-vented p-trap under the sink to be used exclusively for the Reverse
Osmosis drain line. A dry-vented p-trap is a p-trap that has its own vent/stack. Attach
the provided drain line adapter to the p-trap and secure it with the slip joint nut and
washer as shown. Route the drain line from the air gap to the drain line adapter
ensuring that there are no dips, loops or low spots in the line, which could result in a
clogged drain line. The drain line adapter should be aligned vertically such that the
hose connection points in a direction 45° of vertical. (See Fig. 3E.) The drain line

MUST be routed through the air gap provided in the RO water faucet.

OPTION C.
SHARED VENT INSTALLATION— 2 P-TRAP (WET-VENTED) (FIG. 3C)

Install a p-trap under the sink to be used exclusively for the Reverse Osmosis drain line.
A wet-vented p-trap is a p-trap that shares a common vent/stack. Attach the provided
drain line adapter to the p-trap and secure it with the slip joint nut and washer as
shown. Route the drain line from the air gap to the drain line adapter ensuring that
there are no dips, loops or low spots in the line, which could result in a clogged drain
line. The drain line adapter should be aligned vertically such that the hose connection
points in a direction 45° of vertical. (See Fig. 3E.) The drain line MUST be routed
through the air gap provided in the RO water faucet. Locate the p-trap as high as

possible (minimum of 4″above horizontal pipe from second sink or disposer).

SECONDARY RECOMMENDATION

(Use only if option A, B or C is not possible.)

OPTION D.
DRAIN LINE ADAPTER INSTALLATION (FIG. 3D)

DO NOT install the drain line DOWNSTREAM OF A DISPOSAL or in a
HORIZONTAL PIPE. Install the provided drain line adapter under the sink as

shown. The baffle-tee or y-connector shown MUST be in place (purchase and install
if necessary) to prevent a clog in the Reverse Osmosis drain line. Route the drain line
from the air gap to the drain line adapter ensuring that there are no dips, loops or low
spots in the line, which could result in a clogged drain line. The drain line adapter
should be aligned vertically so that the hose connection points in a direction 45° off
vertical. (See Fig. 3E.) This installation MAY result in a slight drain noise in the sink
drain when the Reverse Osmosis system is operating. Rotate the Drain Line adapter tee
assembly slowly until noise is minimized. Generally, 180° opposite the existing
horizontal pipe/baffle-tee is a good orientation.

connections. Select one of the following places to install the faucet:

—IN an existing sink spray attachment or soap dispenser hole
—IN a hole to be drilled in the sink top
—IN a hole to be drilled in the countertop, next to the sink

NOTE: Looking at Fig. 4D, be sure the faucet base will fit flat against the

surface at the selected location so the gasket will seal. The base may
have to be angled sideways or diagonally.

1. If drilling is needed, make a 1-1 ⁄ 4″dia. hole. Be sure to use the

proper procedure for drilling porcelain or stainless steel.

2. Looking at Fig. 4A, insert a screw into the NON-SLOTTED base

mounting hole. Turn a flat nut a few turns onto the screw.

3. Position the base gasket over the mounting hole. Set the base on
the gasket, routing the leadwire through the mounting hole.
Holding the flat nut under the sink with one finger, tighten the
screw until just snug.

4. Turn the remaining flat nut a few turns onto the other screw.
Position the screw in the slotted base mounting hole and tighten
until snug. Make sure the gasket position is properly aligned and

carefully tighten both screws until the base is held firmly in place.
Do not overtighten and break the base.

5. Assemble the top faucet base and hex nut onto the faucet stud

(Fig. 4C). Tighten the nut until snug.

6. Insert washer into tubing adapter. Securely tighten to faucet stud.

7. Take the 27″ length of 3 ⁄ 8″tubing and push one end completely

onto the 3 ⁄8 ″faucet barb fitting (Fig. 4D).

8. Position the Reverse Osmosis system under the sink. Referring to
Fig. 5, page 7, hang the system on cabinet wall.

SANITIZING THE REVERSE OSMOSIS SYSTEM

Sanitize upon installation of the Reverse Osmosis system and after servicing inner
parts of the Reverse Osmosis system, including replacement of prefilter, postfilter
and Reverse Osmosis cartridge. It is important to wash hands with anti-bacterial
soap before handling inner parts of the system.

CAUTION: If installing unit in New Construction, ensure house plumbing is flushed
thoroughly before opening the water supply valve. Also, before sanitizing, be sure to
remove all cartridges as follows. Chlorine will destroy the Reverse Osmosis cartridge.

1. Be sure the water supply valve to the Reverse Osmosis system is turned off and the

RO water faucet is open. Allow the system to drain completely (this takes several
minutes).

2. Place a dry towel under unit. Remove the clamp retainers and clamp
sections from top of unit.

3. Lift the Reverse Osmosis cap straight up (a slight resistance is normal) from
the Reverse Osmosis housing (no need to disconnect tubing) and move aside.

NOTE: If the cap o-ring seal remained in the Reverse Osmosis housing,
replace it on the cap.

4. Remove the Reverse Osmosis cartridge and outer prefilter cartridge from

the Reverse Osmosis housing and place in a clean plastic bag. Dispose of
water from the Reverse Osmosis housing.

5. Fill the Reverse Osmosis housing with fresh cold water, to about 1″ from the top.

Add one ounce (2 tablespoons) of ordinary 5.25% household chlorine bleach
and mix into the water. DO NOT ADD CHLORINE FIRST. Concentrated
chlorine may damage plastics.

6. Replace Reverse Osmosis cap, with the o-ring, and install the clamp retainers.

7. Close the red tank shutoff valve and disconnect postfilter at the tank shutoff valve.

Connect the Reverse Osmosis product water tubing (disconnect at electronics box)
directly to the tank shutoff valve, isolating the carbon postfilter as shown in Fig. 6B.

8

. Open the red tank shutoff valve and the water supply valve to the Reverse Osmosis system.

Allow system to fill for one minute. Now open the RO water faucet, locking the lever
upward against the spout.

9. Allow water to flow through the Reverse Osmosis system until all the bleach odor is
gone (approximately 20 minutes).

10. Turn off the water supply valve to the Reverse Osmosis system. Close the RO water
faucet AFTER the water flow stops.

11. Close the red tank shutoff valve. Disconnect the water product line from the red tank
shutoff valve and connect to the electronics box. Reconnect postfilter line to red tank
shutoff valve. Open red tank shutoff valve.

12. a. Repeat steps two and three. Be careful of water in the Reverse Osmosis housing.

Dispose of water.

b. Replace the Reverse Osmosis cartridge with the o-ring seal downward and the

prefilter cartridge with “this side up” facing upward. BE SURE HANDS HAVE

BEEN CLEANED WITH AN ANTI-BACTERIAL SOAP.

PRESSURE TESTING THE SYSTEM

—DO THE SANITIZING PROCEDURE BEFORE PRESSURE
TESTING—INSTALLATION CHECKLIST

1. Open the water supply valve to the Reverse Osmosis system and

open the storage tank shutoff valve.

2. Check all connections for LEAKS.

3. In about 4 hours, pressure will build in the Reverse Osmosis

system. Carefully recheck all fittings and connections for water
leaks. Correct leaks if any are found.

4. Fill sink(s) 1/2 full of tap water and drain, checking drain

plumbing for leaks.

PURGING THE SYSTEM

1. Wait about 4 hours for the storage tank to fill.

2. Open the RO faucet until the tank is empty and flow stops.

3. Close the RO faucet and repeat these steps three more times.

The system is ready to make product water for use.

WARNING: Initially, the Reverse Osmosis cartridge
contains a food grade preservative that has to be purged
from the system before first use or whenever Reverse
Osmosis cartridge is replaced. The preservative will give
product water an unpleasant taste and odor.

INSTALLATION CHECKLIST

1. Are all tubing connections tightened? Do they run between the

points shown? No leaks!

2. Is the faucet base leadwire connected to the electronics box

leadwire?

3. Is the battery holder connected to the electronics box and are

the batteries installed in the holder correctly?

4. Did you use drain option B, C or D? Make sure the 3 ⁄8 ″drain

tubing, from the faucet to the drain point, is without loops,
dips, or low-spots.

5. Is the tank shutoff valve in the open position?

6. Is the water supply shutoff valve open?

7. Did you sanitize and purge the system?

WHAT THE REVERSE OSMOSIS SYSTEM DOES

Reverse Osmosis removes Total Dissolved Solids (TDS) and
organic matter from water by diffusing it through a special
membrane. The membrane separates minerals and impurities
from the water and they are flushed to the drain. High quality
product water goes directly to the drinking water faucet or to the
storage tank. The system makes a good supply of drinking water
each day (see

Product Specifications

). How much it makes depends

on the feed water supply pressure, temperature, and quality.
The system includes an electronic faucet assembly with an

integrated testing feature. When water is taken from the faucet,
a flashing green indicator light means TDS removal is within
specified limits and that water quality is good.

The prefilter and postfilter are replaceable cartridges. The carbon
prefilter removes chlorine while also filtering sediments. The
postfilter removes any other undesirable tastes and odors before
you use the water.

THE GE ELECTRONIC MONITOR SYSTEM

Indicator lights on the faucet base show Reverse Osmosis
performance when the faucet is open to dispense water.

Flashing Green Light—The Reverse Osmosis system is providing
high quality drinking water.

NOTE: If the Reverse Osmosis system is connected to the
refrigerator, this light will also flash when the icemaker or
dispenser is in use.

The green light may stop flashing when the supply of Reverse
Osmosis water is nearly gone and flow from the RO water faucet
decreases. This is a normal condition.

Flashing Amber “FILT” Light—The prefilter and postfilter cartridges
need replacing. This occurs after 6 months or 900 gallons of
product water use, whichever occurs first. Also, replace the 4 “AA”
alkaline batteries in the electronics box. Good batteries are needed
to ensure correct indicator light operation. Weak batteries may
give a false “RO” light indication. Changing the batteries resets the
6 month or 900 gallon period.

Flashing Amber “RO” Light—The Reverse Osmosis cartridge is no
longer removing at least 75% of the Total Dissolved Solids (TDS)
from the supply water. The Reverse Osmosis cartridge, flow
control, and screen need replacing.

NOTE: Disregard initial or short periods (a few seconds) of the
flashing “RO” light. Long periods of limited or no use can cause
the TDS levels to temporarily change.
