Unpacking and Inspection
Be sure to check the entire unit for any shipping damage or lost parts. Also note damage
to the shipping cartons. Contact US Water Systems at 1-800-608-8792 to report any ship-
ping damage within 24 hours of delivery. Claims made after 24 hours may not be honor-
ed. Small parts, needed to install the unit, will be in a parts bag. To avoid loss of the small
parts, keep them in the parts bag until you are ready to use them.
Safety Guide
• Check and comply with your provincial /
state and local codes. You must follow
these guidelines
• Use care when handling the RO system.
• The RO system works on 110 volt electri-
cal power only. Be sure to use only the
included transformer.
• Transformer must be plugged into an in-
door 120 volt, grounded outlet only.
•WARNING: This system is not intended
for treating water that is microbiologically
unsafe or of unknown quality without ad-
equate disinfection before or after the
system. Contact US Water Systems for
disinfection treatment equipment.

Proper Installation
This RO system must be properly installed and located in accordance with the Installation
Instructions before it is used or the warranty will be void.
•DO NOT install or store where the sys-
tem will be exposed to temperatures be-
low freezing or exposed to any type of
weather. Water freezing in the system will
break it. Do not attempt to treat water
over 100°F.
•DO NOT install in direct sunlight. Exces-
sive sun or heat may cause distortion or
other damage to non-metallic parts.
• Properly ground to conform with all gov-
erning codes and ordinances.
• Use only lead-free solder and flux for all
sweat-solder connections, as required by
state and federal codes.
• Maximum allowable inlet water pressure
is 125 psi. If daytime pressure is over 80
psi, night time pressure may exceed the
maximum. Use a pressure reducing valve
to reduce the pressure.
•WARNING: Discard all unused parts and
packaging material after installation.
Small parts remaining after the installa-
tion could be a choke hazard.

Introduction
Professional-Grade Raptor RO outperforms the field with quality and longevity.
The 500 - 750 GPD Raptor RO can sit on a counter, shelf, or the floor. Its steel powder
coated frame is corrosion-proof and the system utilizes three stages of filtration ahead of
the membrane.
Features
• Three stages of Pre-Filtration
• Single (500 GPD) or Dual (750 GPD) TFC high-flux reverse osmosis membrane
• 50% recovery rate
• Includes pressure gauges (pump pressure and output pressure)
• Bulkhead quick-connect fitting makes it truly "plug n' play"
• 5-Year Factory Warranty
• Made in USA
• Compact design is at home just about anywhere
• Cover removes easily for service.
Four Step Purification Process
1. 5 Micron Sediment Filtration
2. Carbon Block Pre-Filter
3. Chloramine Carbon Block Post-Filter
4. Reverse Osmosis Membrane

How the System Works
A pressurized water source is fed to the first pre-filter which is a 5 micron sediment filter.
The water then passes through a GAC and catalytic carbon filter to the solenoid shutoff
valve. The water then goes from the solenoid switch to the booster pump. Water is pres-
surized at the booster pump and then is conveyed to the membranes. Product water (per-
meate) from the membrane filters is conveyed to the inline check valve and then to the
high pressure switch then on to the faucet and water storage tank. Waste water (concen-
trate) from the membrane is conveyed to the flow restrictors / membrane flush valve. The
water leaving the flow restrictors / membrane flush valve is conveyed to an onsite drain.

* If any of the feed water parameters are not within the limits given, contact US Water
Systems for assistance.
NOTE: HIGHER TDS AND / OR LOWER TEMPERATURES WILL REDUCE THE SYS-
TEMS PRODUCTION. 2% OF THE SYSTEM OUTPUT CAN BE LOST FOR EVERY DE-
GREE "F" BELOW 77.
• Do not use where the water is microbiologically unsafe or of unknown quality without
adequate disinfection before or after the system.
• Pretreatment must be sufficient to eliminate chemicals, organics or inorganics that
could attack the membrane material. Always turn off the unit, shut off the feed water,
and disconnect the electrical power before working on the unit.
• Never allow the pump to run dry.
• Never allow the unit to freeze or operate with a feed water temperature above 100°F.

Rejection, Recovery & Flow Rates
The US Water Systems Raptor reverse osmosis system is designed to produce permeate
water at the capacities indicated by the suffix in the systems name under the conditions
listed above. For example, the RPT-500 produces 500 gallons per day of permeate water
at the listed operating test conditions.
The amount of total dissolved solids (TDS) rejected by the membrane is expressed as a
percentage. For example, a 98.5% rejection rate means that 98.5% of total dissolved sol-
ids do not pass through the membrane. To calculate the % rejection, use the following for-
mula:
•% Rejection = [(Feed TDS - Product TDS) / Feed TDS] x 100
• Example: 98.5% = [(550 - 8.25) / 550] x 100
NOTE: ALL TDS FIGURES MUST BE EXPRESSED IN THE SAME UNITS, TYPICALLY
PARTS PER MILLION (PPM) OR MILLIGRAMS PER LITER (MG/L).
The Raptor reverse osmosis system is designed to reject up to 98.5% NaCl, unless com-
puter projections have been provided or stated otherwise.
The amount of permeate water recovered for use is expressed as a percentage. To calcu-
late % recovery, use the following formula:
•% Recovery = (Product Water Flow Rate / Feed Water Flow Rate) x 100
• Example: 40% = (2.78 / 7.0) x 100
NOTE: ALL FLOW RATES MUST BE EXPRESSED IN THE SAME UNITS, TYPICALLY
GALLONS PER MINUTE (GPM).
