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.

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).
SPECTRUM 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.

Electrical
The motor used on the SPECTRUM Systems are pump and motor combinations. The motor is available in
220V 50Hz 1 Phase. Each SPECTRUM System is equipped with an 2.4 metre electrical cord w/o plug.
Ensure that the electrical circuit supplying the system is compatible with the requirements of the specic
SPECTRUM model being installed.
NOTE: It is recommended that a qualified electrician wire the system in accordance with
thelocal and national electrical codes.
CAUTION NOTE: To reduce the risk of electrical shock the incoming power supply must include a
protective earth ground.
SPECTRUM Systems are controlled with a high pressure switch in the permeate line. The liquid pressure
switch turns the system on when the permeate water pressure drops below 2.8 bar and off when the
permeate water pressure exceeds 4.1 bar.
Pre-ltration
SPECTRUM Systems are supplied with a carbon block lter. Change the cartridge once a month or when a
1 bar differential exists between the two pre-lter gauges.
NOTE: The system must be operated on ltered water only.
Pump
The pump type used on the SPECTRUM Systems is multi-stage centrifugal stainless steel. If any damage
occurs to the system’s pump a re-build kit may be available. Contact the local dealer or distributor and
inform them of the system pump model.
Mounting
The free standing system should be bolted down or securely fastened in compliance with local regulation
standards.

Membrane Installation,
Removal & Replacement
Installing and replacing membranes in the membrane housings is an easy process if the correct information
and tools are at hand. Refer to the following instructions when removing or replacing membrane elements:
NOTE: All pressure gauges must read zero before proceeding. Before attempting, disconnect
the power from the system and bleed all water pressure from the system.
1. Remove the black end cap from the top of the membrane housing. This is done by removing the yellow
locking clip and then the white snap ring on the membrane housing end.
2. Remove the replacement membrane element(s) from the shipping box; the membrane(s) should be
contained within a plastic oxygen barrier bag.
3. Cut the bag open as close as possible to the seal at one end of the bag, so the bag may be re-used if
necessary.
4. Make sure that all parts are clean and free from dirt. Examine the brine seal and permeate tube for
nicks or cuts.
5. Flow directions should be observed for installation of each element into their respective membrane
housings.
NOTE: Wear gloves for the following steps in order not to contaminate the membrane.
Replacing the Membrane Element
NOTE: The brine seal must be in the same position for each membrane element housing.
The brine seal is a rubber seal that protrudes on one side of the membrane and is always on
the feed side of the membrane element. On SPECTRUM Systems the brine seal should be
on the top side of the membrane housing.
1. Remove one membrane element at a time from the top of the membrane housings. Long nose pliers
may be necessary to pull the old membrane element out of the membrane housing.
2. Lubricate the brine seal with a non-petroleum based lubricant. Do not use a petroleum-based lubricant.
3. Install membranes with brine seal location depicted (Figure 2).
4. With a smooth and constant motion, push the membrane element into the housing so the brine seal
enters the housing without coming out of the brine seal groove.
5. Once the membrane has been fully inserted into housing re-install black end plug, white snap ring
(ensure the white snap ring is fully seated all the way around end plug) and yellow locking clip.
6. Reconnect any ttings that may have been disconnected when the membrane housing were
disassembled.
7. To start-up the system refer to the initial start-up section of this manual.
