Introduction
Thank you for your purchase of a state of the art Watts KwikChange™ Zero Waste Reverse Osmosis (RO) water treatment
system. Water quality concerns are becoming more of a focus for
the public. You may have heard about contaminants in the drinking
water, such as Arsenic, Perchlorate, Chromium, Cryptosporidium
or Giardia. There may also be some local water issues such as high
levels of Lead and Copper. This Watts water treatment system has
been designed and tested to provide you with high-quality drinking water for years to come. The following is a brief overview of the
system.
Your Reverse Osmosis System:
Osmosis is the process of water passing through a semi-permeable
membrane in order to balance the concentration of contaminants
on each side of the membrane. A semi-permeable membrane is a
barrier that will pass some particles like clean drinking water, but not
other particles like arsenic and lead.
Reverse osmosis uses a semi-permeable membrane; however, by
applying pressure across the membrane, it concentrates contaminants (like a strainer) on one side of the membrane, producing crystal
clear water on the other. This is why RO systems produce both clean
drinking water and rinse water that is flushed from the system. This
reverse osmosis system also utilizes carbon block filtration technology, and can therefore provide a higher quality drinking water than
carbon filtration systems alone.
Your system is a three stage RO which is based upon separate
treatment segments within the one complete water filtration system.
These stages are as follows:
Stage 1 – Carbon filter, recommended change 6 months.
The first stage contains a 5-micron carbon block filter. This
helps ensure that chlorine and other materials that cause
bad taste and odor are greatly reduced.
Stage 2 – Membrane, recommended change 2 to 5 years.
Stage-2 is the heart of the reverse osmosis system, the
RO membrane. This semi-permeable membrane will
effectively take out TDS, Sodium and a wide range of
contaminants such as Percholate, Chromium, Arsenic,
Copper, Lead as well as Cysts, such as Giardia and
Cryptosporidium. Because the process of extracting this
high-quality drinking water takes time, your RO water
treatment system is equipped with a storage tank.
Stage 3 - Carbon post filter, recommend change 12 months.
The final stage is a high-quality carbon filter. Drinking water
enters this filter after the water storage tank, and it is used
as a final polishing filter.
Note: Filter life may vary based upon local water conditions or
use patterns.
System Maintenance
Just because you cannot taste it, does not mean that it is not there.
Contaminants such as Lead, Chromium and Arsenic are undetectable to the taste. Additionally, over time if you do not replace the
filter elements, other bad tastes and odors will be apparent in your
drinking water.
This is why it is important to change out your filters at the recommended intervals as indicated in this system manual. When replacing
the filter elements, pay special attention to any cleaning instructions.

before or after the system. System is intended to be
installed on the cold water line only.
Operating Temperatures Maximum 100°F (37.8°C) Minimum 40°F (4.4°C)
Operating Pressure
pH Parameters Maximum 11 Minimum 2
Iron Maximum 0.2 ppm
TDS (Total Dissolved Solids) < 1800 ppm
Turbidity < 5NTU
Hardness: Recommended hardness not to exceed 10 grains per
gallon, or 170ppm. System will operate with hardness over 10 grains
but the membrane life may be shortened. Addition of a water softener may lengthen the membrane life.
Water Pressure: The operating water pressure in your home should
be tested over a 24 hour period to attain the maximum pressure.
If the incoming water pressure is above 85psi a pressure regulator
is recommended, and if over 100psi then a pressure regulator is
required.
Copper Tubing: Reverse Osmosis water should not be run through
copper tubing as the purity of the water will leach copper causing
an objectional taste in water and pin holes may form in the tubing.
Watts supplies speciality filters that can be used if copper tubing
follows the Reverse Osmosis unit. Be sure to follow any state or local
regulations during installation.
Note: RO unit must be installed a minimum of 25 Pipe feet from
water heater.
Maximum 85psi
(6.0 kg/cm2)
Minimum 40psi
(2.80 kg/cm2)
***IMPORTANT NOTICE***
System was tested in a laboratory setting utilizing a hot water
heater of 40 gallons set at 120°F. Performance may vary if
your heater is smaller than 40 gallons or set above 120°F,
contact the manufacturer for additional details.
System should not be used on homes equipped with a backflow prevention on the hot water heater. This device is 100%
efficient, as no water is lost to drain in the production of the
RO water.
Drill a Hole for the Faucet in a Porcelain Sink
Note: Most sinks are predrilled with 1½" or 1¼" diameter hole
that you can use for your RO faucet. (If you are already using it
for a sprayer or soap dispenser, see Step 2).
Caution: Porcelain sinks are extremely hard and can crack or
chip easily.
Use extreme caution when drilling. Watts accepts no responsibility for damage resulting from the installation of faucet.

How To Use the Quick-Connect Fittings For Tubing Connections
To make a connection, the tube is simply pushed into the fitting.
Place a piece of tape
1
⁄2" from end of tube to indicate how far the
tube should be inserted. The unique patented locking system holds
the tube firmly in place without deforming it or restricting flow.
NOTE: These diagrams are just to show how the quick-connect
fittings work, your product may not have this exact connector
part.
It is essential that the outside diameter be free of score marks and that burrs and
sharp edges be removed before inserting into fitting.
Push the tube into the fitting, to the tube stop. The collet (gripper) has stainless
steel teeth which hold the tube firmly in position while the O-ring provides a permanent leak proof seal.
To disconnect, ensure the system is depressurized before removing the tube. Push
in collect squarely against face of fitting. With the collet held in this position, the
tube can be removed. The fitting can then be reused.
Fitting grips before it seals. Ensure tube is pushed into the tube stop.
Pull on the tube to check that it is secure. It is a good practice to test the system
prior to leaving site and /or before use.
