Introduction
SPECTRUM SRO Systems are durable and high performance, designed to offer years of reliable
operation providing the proper care is taken. This manual outlines installation, operation, maintenance
and troubleshooting details vital to sustained performance.
If a system is altered at the site of operation, or if the feed water conditions change contact your local
dealer or distributor to determine the proper recovery for the application.
NOTE: In order to maintain the manufacturer’s warranty an operating log must be maintained
and copies will need to be sent to your local dealer or distributor for review.
NOTE: Prior to operating or servicing the Reverse Osmosis System this manual must be
read and fully understood. Keep this and other associated information for future reference
and for new operators or qualied personnel near the system.

• 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 START THE PUMP WITH THE CONCENTRATE VALVE CLOSED.
• NEVER ALLOW THE UNIT TO FREEZE OR OPERATE WITH A FEED WATER TEMPERATURE
ABOVE 38°C.
Safety
The safety section of this manual outlines the various safety headings used throughout this manual’s
text and are enhanced and dened below:
!
CAUTION: Indicates statements that are used to identify conditions or practices that could
result in equipment or other property damage.
WARNING: Indicates statements that are used to identify conditions or practices that could
result in injury or loss of life. FAILURE TO FOLLOW WARNINGS COULD RESULT IN SERIOUS
INJURY OR EVEN DEATH.
CAUTION
CAUTION
CAUTION
DO NOT UNDER ANY CIRCUMSTANCE REMOVE ANY CAUTION, WARNING OR OTHER
DESCRIPTIVE LABEL FROM THE SYSTEM.
PLEASE READ THE ENTIRE MANUAL BEFORE PROCEEDING WITH THE INSTALLATION
AND STARTUP. FAILURE TO FOLLOW THE ATTACHED INSTRUCTIONS OR OPERATING
PARAMETERS MAY LEAD TO THE PRODUCT’S FAILURE, WHICH CAN CAUSE PROPERTY
DAMAGE AND/OR PERSONAL INJURY.

Feed Water &
Operation Specifications
Feed water quality has the greatest effect on the operation of Reverse Osmosis Systems, therefore it is
important to ensure that the feed is within the operating parameters.
Feed Temperature (ºC) 4 - 29
System Inlet Pressure (bar) 3.1 - 5.8
Maximum Operating Pressure (bar) at Temperature (ºC) 13.8 at 25
Maximum SDI Rating < 3
Maximum Turbidity 1 NTU
Maximum Free Chlorine and/or Chloramines 0 PPM
pH (continuous) 5 - 11
pH (cleaning - 30 min) 2 - 12
Operating Limits
Operating Parameters:*
Feed Water Requirements:*
*If any of the feed water parameters are not within the limits given, consult the local dealer or distributor for assistance.
NOTE: Higher TDS and/or lower temperatures will reduce the system’s production.
NOTE: It is very important to meet the minimum feed water requirements. Failure to do so
will cause the membranes to foul and void the manufacturer’s warranty.

Rejection, Recovery &
Flow Rates
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 the total dissolved solids do not pass through the
membrane. To calculate the % rejection use the following formula:
% Rejection = [(Feed TDS - Product TDS) / Feed TDS] x 100
Example: 98.5% = [(550-8.25) / 550] x 100
NOTE: All TDS gures must be expressed in the same units, typically parts per million (ppm)
or milligrams per litre (mg/l).
S
PECTRUM Reverse Osmosis Systems are designed to reject up to 98.5% NaCl unless computer projections
have been provided or stated otherwise.
The amount of permeate water recovered for use is expressed as a percentage. To calculate % recovery
use the following formula:
% Recovery = (Product Water Flow Rate / Feed Water Flow Rate) x 100
Example: 50% = (1.02/2.04) x 100
NOTE: All ow rates must be expressed in the same units, typically litres per minute (lpm).

System Requirements &
Operation Guidelines
Plumbing
The membranes and high pressure pumps used on the SPECTRUM Systems require continuous ow of
water with a minimum feed pressure of 3.1 bar and must not exceed 38°C.
Feed Water Connection
1. Locate the 3/4" FNPT solenoid valve feed water inlet.
2. Attach the inlet piping to the 3/4" FNPT solenoid valve feed water inlet.
3. Be certain that all of the components of the feed water are soluble at the concentrations attained in
the system.
NOTE: Feed line must be a minimum of 1/2".
Permeate (Product Water) Connection
Locate the threaded 1/2" MNPT tting on the ow meter labelled “permeate” and attach to storage tank.
The permeate line can be run to the holding tank with PVC tting or other FDA approved materials. This is
so the material being used does not dissolved into the permeate water.
NOTE: The pH of the reverse osmosis permeate water will typically be 1 or 2 pH units lower
than the feed water pH. A low pH can be very aggressive to some plumbing materials such
as copper piping.
Concentration (Waste Water) Connection
Locate the 1/2" MNPT connector on the ow meter labelled “concentrate” and attach the line to a drain.
Run the concentrate line to an open drain in a free and unrestricted manner (no back pressure).
CAUTION
NOTE: Any restrictions or blockage in the drain line can cause back pressure, which
will increase the system’s operating pressure. This can result in damage to the system’s
membranes and components.
