How Reverse Osmosis works –

Your new Reverse Osmosis (RO) system is composed of a 3-stage system manifold, a 3000 series pre-filter, the reverse osmosis membrane, a storage
tank, a 3000 series post-filter and a faucet to deliver the filtered water to your countertop. First the water goes to the pre-filter, which is a replaceable
cartridge that reduces chlorine, odor, sand, silt, dirt, and other sediments to improve the taste of your water. Next, the water flows to the Reverse
Osmosis
into the storage tank. A diaphragm inside the tank keeps the water pressurized to about 30 psi when the tank is full. This is what provides the fast flow
to the faucet. When the tank is empty, it

system drops and the shutoff valve opens to allow the tank to be re-filled.

Reverse Osmosis uses a membrane that is semi-permeable, allowing cleaner water to pass through it, while rejecting the contaminants that are too
large to pass through the tiny pores in the membrane. This quality reverse osmosis system uses a process known as cross-flow to allow the membrane

CAUTION CAUTION

This filter must be protected from
freezing, which can cause cracking
of the filter and water leakage.

Because of the product’s limited service life and to prevent costly repairs or possible water damage, we
strongly recommend that the housing be replaced every five years. If the head of the filter has been in use
for longer than this period, it should be replaced immediately. Date the top of any new head to indicate the
next recommended replacement date.

Plan Your Installation

It is recommended to read through the entire manual before beginning your installation.
Follow all steps exactly. Reading this manual will also help you get all the benefits

from your system.
Your Reverse Osmosis Drinking Water System can be installed under a sink or in a
remote location. Typical remote sites are a basement or laundry room or utility room. Review
the location options below and determine where you are going to install your system.

Under The Sink Location

The Reverse Osmosis Filter Assembly and storage tank are normally installed in a
kitchen or bathroom sink cabinet. See Fig. 1.
A suitable drain point is needed for reject water from the Reverse Osmosis Filter.

Remote Location

You can also locate the Reverse Osmosis Filter Assembly and storage tank in a remote
location away from the Reverse Osmosis Faucet. You will need a nearby water
source and drain point. See Fig. 2.

Install Kitchen Faucet Adapter

CHOOSE TYPE OF WATER FITTING TO INSTALL

1

Locate the cold water line in the sink cabinet. Turn off the cold water supply to the sink.

NOTE: If uncertain about which line supplies the cold water, turn on the hot water to the faucet. Allow the water to heat up and carefully
feel the pipes under the sink. The pipe that remains cool to the touch is the cold water supply.

2

Turn on the kitchen faucet to release pressure and allow water to completely drain from the line.

3

Disconnect the cold water line from the 1/2" threaded stem on the bottom of the kitchen faucet.

NOTE: If rigid plumbing pipe (metal or plastic) is used, you may need to shorten the supply pipe using a hacksaw or pipe cutter to
accommodate the Kitchen Faucet Adapter.

4

Holding the Kitchen Faucet Adapter in an upright position (see diagram), screw onto the threaded faucet stem.

5

Screw the cold water supply line to the male threads of the Kitchen Faucet Adapter using the nut that was connecting the cold
water line to the kitchen faucet previously. For a secure fit, tighten the nut using an adjustable wrench.

Be sure that all electrical appliances and outlets are turned off at the
circuit breaker before working in cabinet area.

Drain Connector Installation

Choose the drain outlet location. See Fig. 1 (page 3)

NOTE: Extra care should be taken when entering drains near dishwashers or food waste disposals, as backflow
may occur through the air gap and cause flooding.

1

Remove protective cover from back of Foam Seal Knock out center hole and align holes then attach to Drain Connector
front plate .

2

Position the Drain Connector on the sink drain pipe above the drain trap. Allow room for drilling. Tighten Screws and

Nuts securely.

3

Use a battery powered or properly grounded drill. Using the Drain Connector port as a drill guide, drill a 7/32” hole through

the wall of the drain pipe. Do NOT penetrate the opposite side of the pipe and be careful not to damage the side of the drain
port fitting.

Install RO System and Drain In Remote Location

INSTALL A REMOTE DRAIN POINT AND AIR GAP (Remote Location)
You can also run the drain tubing to an existing drain in the house. A floor drain, laundry tub, standpipe,
sump, etc. are suitable drain points. This type of drain is preferred over the drain connector. Check your
local codes. Longer lengths of tubing (see parts list in manual) may be needed.

Always be sure to provide an air gap between the end of the hose and the drain point. This will prevent
wat

er from backing up into the system. Air gaps are required code in most areas.

TO INSTALL A REMOTE DRAIN POINT, COMPLETE THE FOLLOWING STEPS:

1

Remove the 1/4" Red Plastic Tubing from the RO Faucet Body by pulling gently.

2

Determine if this length is long enough to reach the drain point. If it is, then insert Restrictor in end of
tubing and then insert this end of tubing into drain port on RO Membrane Filter .

If not, replace the 1/4" Red Plastic Tubing with an adequate length of tubing to reach the drain point.

3

Then insert Restrictor in end of tubing and then insert this end of tubing into drain port on RO
Membrane Filter . Refer to Step 6 in manual on how to disconnect and connect tubing.

Sanitize, Test and Purge System

SANITIZE THE SYSTEM

Sanitizing is recommended immediately after installation of the RO Filter System Assembly. It’s also recommended after servicing inner
parts. It is important that the person installing or servicing the system have clean hands while handling inner parts of the system.
Complete the following steps to sanitize the system.

1

Make sure the water supply to the RO Filter System Assembly is off.

2

Open the Reve

Add 3 ml. of bleach into the open end of Water Storage Tank White Plastic Tubing S . Handle bleach according to
manufacturer’s instructions.

6

Re-connect Water Storage Tank and White Plastic Tubing S to Tank Connector D fitting.

7

Sanitizing the RO Filter System Assembly will be completed during the pressure test and purging following steps below.

NOTE: The bleach must be completely removed from the system before drinking the RO water. See purging instructions below.

P

RESSURE TEST THE SYSTEM

IMPORTANT: Complete the sanitizing procedures above before pressure testing.

1

Open the cold water supply valve to the RO Filter System Assembly. See page 3, Fig. 1

2

Open the kitchen faucet. This will purge air from the plumbing system. Close kitchen faucet when water runs smooth.

3

Ensure RO Faucet is closed.

4

Pressure will start to build in the RO Filter System Assembly in about 2 hours. Carefully inspect all fittings and connections while the

RO Filter System Assembly buil

exist, refer to the troubleshooting chart or call the toll free number.

URGING THE SYSTEM

1

Open the Reverse Osmosis Faucet and let water flow through the system for a 24 hour period. Water will flow heavily until tank
becomes empty, and then it will be a slow drip for the balance of 24 hours.

NOTE: The flow rate will be very slow during the purge.

2

Close the Reverse Osmosis faucet after the 24 hour purge is complete.

3

Your Reverse Osmosis system is ready for use when the purge is complete.

Review the following operating features before using your Reverse Osmosis System:
You will not have filtered water immediately. It will take 1-3 hours to completely fill the storage tank to create liberal flow from the
