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 specic
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.

Operation & Maintenance
DO:
•Change the cartridge lters regularly
•Monitor the system and keep a daily log
•Run the system as much as possible on a continuous basis
•Adjust the system recovery to the recommended value
•Always feed the pump with ltered water
DON’T:
•Permit chlorine to enter or be present in the feed water
•Shut down the system for extended periods
•Close the throttle valve completely
•Operate the system with insufcient feed ow
•Operate the pump dry
The reverse osmosis process causes the concentration of impurities. The impurities may precipitate (come
out of solution) when their concentration reaches saturation levels.
Check the feed water chemistry and pre-treat the water and/or reduce the system’s recovery as required.
If necessary consult the local dealer or distributor.
Pre-lter Pressure Gauges
These gauges measure the feed water pressure when it enters and exits the pre-lter. A pressure differential
of 0.68 - 1 bar or more on the pressure gauge indicates the pre-lter requires servicing. For example, if the
inlet pressure is 2.75 bar the lter should be changed when the outlet pressure is 2 bar or below.
Permeate (product) Flow Meter and Concentrate (waste) ow meter
These ow meters indicate the ow rates of the permeate and concentrate water. The measurements, when
added together, also indicate the feed water ow rate or (total ow rate); if the system is not equipped with
a concentrate recycle valve.
NOTE: Precipitation can scale or foul membranes and must be prevented.
NOTE: Excessive recycling may cause premature fouling /scaling of the membrane elements.
Low Pressure Switch
The low pressure switch shuts off the system when the feed water pressure drops below 1 bar, preventing
damage to the pump. The system restarts automatically when there is a constant pressure of 2.4 bar or more.
NOTE: If you notice the pressure uctuating and the system cycling off and on, turn the
system off and ensure that proper feed ow and pressure are available to the system.

Spectrum
TM
High Pressure Switch
The high pressure switch shuts off the system when the product water pressure exceeds 4.1 bar, preventing
damage to the system. The system restarts automatically when the pressure drops below 2.75 bar.
Pump Throttle Valve
The pump throttle valve is installed as a standard feature on SPECTRUM systems. It provides an adjustment
for pump pressure. As the feed water temperature decreases and/or the feed TDS increases, the system
will require a higher operating pressure to produce the specied permeate ow.
Adjusting the Throttle Valve
To decrease the pressure, turn the handle clockwise. To increase the pressure, turn the handle counter
clockwise, shown in Figure 4.
Figure 4.
Flushing the System
The system should be ushed weekly to remove sediment from the surface of the membranes. To manually
ush the system follow the steps shown below:
1. The system must be operating during the ush procedure.
2. Fully open the concentrate valve (Figure 1, Item 5).
3. Allow the system to run for 10 - 20 minutes.
4. After 10 - 20 minutes, close the concentrate valve to its previous setting. Ensure the proper concentrate
ow rate is going to drain.
5. The system is now ready to operate.
Operation & Maintenance

16
Spectrum
TM
NOTE: Prior to shipping or storing a system for more than three weeks, the system should
be cleaned with an appropriate cleaner, ushed with water and protected from biological
attack with an appropriate solution for membrane elements. The membrane housing(s)
and plumbing lines of the system must be completely drained. Any water remaining in the
plumbing of a system may freeze, causing serious damage.
Preparation for Storage
or Shipment
Preparing the System for Storage
1. Totally immerse the elements in the membrane housing in a solution of 2% M-100 solution, venting the
air outside of the housings. Use the overow technique: circulate the M-100 solution in such a way that
the remaining air in the system is minimised after the recirculation is completed. After the membrane
housing is lled, the M-100 solution should be allowed to overow through an opening located higher
than the upper end of the highest housing being lled.
2. Separate the preservation solution from the air outside by closing all valves. Any contact with oxygen
will oxidise the M-100 solution.
3. Check the pH once a week. When the pH becomes 3 or lower, change the preservation solution.
4. Repeat this process at least once a month.
During the shutdown period, the plant must be kept frost-free and the temperature must not exceed 45°C.
Preparing unit for shipment:
5. Disconnect the inlet, concentrate, pre-lter and permeate plumbing.
6. Drain all water from the pre-lter cartridge housings by unscrewing the housings, removing the pre-
lter cartridge and draining the water from the housings.
7. Disconnect the tubing from the connectors on the permeate and concentrate inlets and outlets.
8. Fully open the concentrate valve.
9. Drain the ow meters.
10. Allow the system to drain for a minimum of eight hours or until the opened ports stop dripping.
After draining is complete, reconnect all plumbing.

Troubleshooting
Abnormal Permeate Flow
Permeate ow should be within 20% of the rated production, after correcting the feed water temperatures
above or below 25°C. Check the permeate ow meter to determine the permeate ow rate.
NOTE: To determine the temperature correction factor, locate the temperature correction
table in this manual and follow the directions.

Membrane Temperature
Correction Factors
Find the temperature correction factor (TCF) in the table below. Divide the rated permeate ow at 25°C by
the temperature correction factor. The result is the permeate ow at the desired temperature (see example).
If the system is rated to produce 18.9 lpm of permeate
water at 25°C, the same system will produce more
water at a higher temperature. It will also produce less
water at a lower temperature. Use the temperature
correction table to obtain the correct ow.
Example:
18.9 lpm @ 15°C (18.90 ÷ 1.422 = 13.29)
18.9 lpm @ 25°C (18.90 ÷ 1.000 = 18.90)
18.9 lpm @ 28.9°C (18.90 ÷ 0.892 = 21.19)
If service assistance is required, please complete the following process:
Contact the local dealer or distributor. Prior to making the call, have the following information available:
system installation date, serial number, daily log sheets, current operating parameters (e.g. ow, operating
pressures, pH, etc.) and a detailed description of the problem.
