Introduction
Thank you for your purchase of the Premier Reverse Osmosis
(RO) water treatment system. This Premier water treatment system
has been designed and tested to provide you with high quality
drinking water when installed, maintained and used in accordance
with the instructions in this Manual, and any requirements of local,
state and federal law. Failure to do so could result in personal injury,
property damage or damage to the equipment. This Manual should
be considered a permanent part of your system and should be kept
available for easy reference by any user.
If this system or any of its parts becomes damaged or needs repair,
turn off the water supply, stop using the system and contact an
experienced service individual immediately.
If on-product labels or this Manual are misplaced, damaged or il-
legible, or if you require additional copies, please contact Watts for
these items at no charge.
If you are ever uncertain about a particular task or the proper method
of operating this system, consult this Manual, contact a licensed
plumber, or contact Watts at 800-752-5582
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 allow clean drinking water through, but will reduce
the passage of containments such as arsenic or lead*. This reverse
osmosis system also utilizes carbon block filtration technology, and
can therefore provide a higher quality drinking water than carbon
filtration systems alone.
*This product cannot effectively reduce the trivalent form of
Arsenic. Please read the Arsenic Fact Sheet and Performance
Data Sheet in the back of this manual for additional information.
The Stages of Filtration
Your system is a four stage RO which is based upon separate
treatment segments within the one complete water filtration system.
These stages are as follows:
Stage 1 – Sediment filter, recommended change 6 months.
The first stage of your RO system is a 5 micron
sediment filter that traps sediment and other particulate
matter like dirt, silt and rust which affect the taste and
appearance of your water.
Stage 2 – Carbon filter, recommended change 6 months.
The second 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 3 - Membrane, recommended change 2-5 years.
Stage three is the heart of the reverse osmosis system,
the 50GPD (Gallons Per Day) RO membrane. This semi
permeable membrane will effectively remove TDS, Sodium
and a wide range of contaminants such as Perchlorate,
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 4 - 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.
NOTICE
Filter & Membrane life may vary based upon local water
conditions and/or use patterns.
Operational Parameters
NOTICE
Installation must comply with State and local plumbing regula-
tions. Do not use with water that is micro biologically unsafe or
of unknown quality without adequate disinfection before or after
the system.
System is intended to be installed using the cold water
supply only.

Hardness
Hardness: Recommended hardness not to exceed 10 grains per
gallon, or 170ppm.
* System will operate with hardness over 10 grains but the mem-
brane 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 100 psi then a water pressure
regulator is required. A booster pump is needed for incoming water
pressure under 40psi.
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 Premier supplies speciality filters (part numbers WP107008,
WP560060 and WP560059) that can be used if copper tubing fol-
lows the Reverse Osmosis unit. Be sure to follow any state or local
regulations during installation.
