Safety Guide
Be sure to check the entire RO system for any shipping damage or parts loss. Also note
damage to the shipping cartons. Contact US Water Systems at 1-800-608-8792 to report
any shipping damage within 24 hours of delivery. Claims made after 24 hours may not be
honored.

Table of Contents
• Check and comply with provincial / state
and local codes. It may be mandatory that
these codes/laws be followed.
• Use care when handling the RO system.
• The RO System works on 110 or 220 volt-
60 Hz 1PH electrical power only.
• DO NOT exceed 150 psi on the pump or
membrane pressure gauge or damage or
injury could occur.

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 it will be ex-
posed to temperatures below freezing or ex-
posed to any type of weather. Water freez-
ing in the system will break it. Do not attempt
to treat water over 100°F.
Do not install in direct sunlight. Excessive
sun or heat may cause distortion or other
damage to non-metallic parts.
Properly ground to conform with all govern-
ing 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 maxi-
mum. Use a pressure reducing valve (PRV)
to reduce the pressure.
RO membranes will degrade in the presence
of chlorine or chloramines. In these condi-
tions, it is wise to consider purchasing a
backwashing carbon filter system with a
chlorine reducing media. Contact US Water
Systems for Chlorine and Chloramine remov-
al equipment.
WARNING: Discard all unused parts and
packaging material after installation. Small
parts remaining after the installation could be
a choke hazard.

Component Identification
1. Solenoid Valve - Turns ON/OFF Feed Water Supply when the tank input circuit is opened
2. 5 Micron Sediment Pre-filter - Removes Sediment from the Feed Water
3. Filter IN Pressure Gauge - Monitors Feed Water Pressure prior to the Pre-filters
4. Pump Pressure Gauge- Monitors the Membrane/Pump pressure during operation. WARNING! Do not ex-
ceed 150psi.

5
Component Identification
5. Computer Control - The Minitrol Controls ON/OFF Function as well as Fail Safe Switches.
6. Recycle/Recirculation Valve - Controls the amount of Concentrate Water that is Fed back to the Mem-
branes for Recycle
7. Concentrate/Waste Valve - Controls the amount of Concentrate Water going to the drain for waste.
8. Pump and Motor - Boosts the Feed Water Pressure to the Membranes

6
Component Identification
9. Throttle Valve - Adjusts the Boost Pressure to the Membranes. WARNING! Do not exceed 150psi.
10. Permeate/Product Flow Meter - Monitors the amount of Permeate Water going to the storage or distribution
system.
11. Concentrate Flow Meter - Monitors the amount of Concentrate Water going to drain.
12. Recycle/Recirculation Flow Meter - Monitors the amount of Concentrate Water being recycled to the Mem-
branes.

7
Component Identification
13. Low Pressure Switch - Shuts the system down as a fail safe in a Low Feed Water Pressure condition.
This pressure switch is in the RO controller.
14. Membrane Pressure Vessels - Holds the Membranes
15. Power Supply Cord
16. Injection Pump Electrical Connection
17. Tank Level or Pressure Shutoff Connections
WARNING! This input is a NO VOLTAGE dry contact. DO NOT
apply voltage to this input!
