1.0 FOREWORD
1.1 Congratulations on purchasing an Evolution Low Salt Oxidiser & Sanitiser for your
swimming pool. This system is designed for reliability and easy operation to provide
many years of trouble-free service. Please read the instructions thoroughly before
operating the unit. If you have any concerns or require further assistance, please do not
hesitate to contact our friendly staff or any of our Evolution distributors.
2.0 POOL CHEMISTRY
2.1 It is important to note that the Low Salt Oxidiser does not maintain the water chemistry
of the swimming pool water; it simply sanitises the water from a mild salt / mineral
blend solution. To ensure the water is chemically balanced within the guidelines listed
below, the pool water should be tested regularly at a pool shop to maintain a sparkling
and healthy pool.
pH 7.2 – 7.6
Total Alkalinity 90 – 150ppm
Cyanuric Acid 40 – 65ppm
Salinity 1,800 – 4,000ppm
Free Chlorine 1.5 – 3.0ppm
2.2 The Low Salt Oxidiser is designed to operate within a salinity range of 1,800 – 4,000
parts per million (ppm). This salinity range can be achieved by adding regular pool salt,
Pure Minerals Ultra Blend™, or other mineral blend products to the pool. To correctly
dose the pool water with Pure Minerals Ultra Blend™, follow Sections 6.0 and 7.0 of
this manual.
2.3 Note: Before adding minerals and salt to the swimming pool, please switch the
Oxidiser off to avoid overload damage. FAILURE TO DO SO MAY VOID THE WARRANTY.
2.4 Before initial startup, it is recommended to manually add chlorine to the swimming pool
as the Low Salt Oxidiser is designed to maintain oxidiser levels over time and not run
for unnecessarily long hours to build an acceptable oxidiser level. The manual addition
of chlorine may also be required for unforeseen situations where the swimming pool
has a high sanitisation demand, for example, after a large bather load or heavy rain.

3.0 CELL INSTALLATION
3.1 The Low Salt Oxidiser cell housing must be plumbed into the return line after the filter.
Please refer to the installation diagram, Fig.1, below for the preferred method. The cell
housing has allocations for either 50mm PVC pipe or 40mm PVC pipe using the supplied
PVC reducing bushes.
3.2 If a heater is plumbed into the system, then the cell housing must be installed after the
heater in the return line to protect the elements or heat exchanger. If a solar heating
system is fitted, the cell housing should be installed after the return line comes back
from the roof if it rejoins the main swimming pool return line.

4.0 POWER PACK INSTALLATION
4.1 The Low Salt Oxidiser power pack is wall mounted using the supplied mounting bracket
or directly hanging on the wall with screws (300mm centres). The power pack must be
mounted at least 1 metre above the ground and 3 metres or more from the pool edge.
4.2 It is strongly recommended that the power pack be installed where it is protected
from the elements. Rain and sunlight will prematurely age the unit. It should also be
mounted in a position where it is away from accidental water spray. The power pack
should be installed so that adequate airflow can circulate freely around the unit to
allow for sufficient ventilation.
4.3 The power pack comes with a standard 230V 10A power cable that is to be connected to
mains power. Plug the power cable into a suitable weatherproof outlet.
4.4 The power pack is fitted with a 230V 10A power socket located on the right-hand
underside of the power pack. The pool pump should be plugged into this socket so that
the Oxidiser and pump activate together when the timer switches on at the allocated
time settings. Failure to plug the pool pump into this socket could lead to the Oxidiser
staying on with no water circulation. Without circulation, and in the event of a water
probe failure, overheating and a possible gas build-up may occur. This build-up may
damage the cell housing.
4.5 The Oxidiser cell cable is connected to the power pack at the junction box on the
underside of the unit. With power off, remove the protective cover from the junction
box and insert the cell cable wires to the terminals, with the thin wire connecting to the
middle position. The screws must be firmly tightened so there is solid contact between
the wires and the terminals. Replace the protective cover back over the junction box.

5.0 OPERATION
5.1 The control interface on the power pack consists of the following:
Fig. 3
1. Oxidiser Output LEDs
If the correct salinity level is maintained in the water, all ten lights will illuminate at full
oxidiser output (100%). Each light represents a 10% incremental output. If only LED 1
(first indicator light) flashes on, the pool water salinity is below 1,500ppm, and the unit
has gone into the ultra-low salinity cutout mode. There is no oxidiser output in this
mode, and the salinity must be increased for the Oxidiser to return to regular operation
(see manual Sections 6.0 and 7.0). The Oxidiser Output dial (2 in Fig. 3) will increase or
decrease the output to suit the pool requirements. If all of the indicator lights flash, then
there is a water flow fault.
2. Oxidiser Output
The Oxidiser Output dial determines the amount of oxidiser production. By simply
turning the control clockwise, oxidiser output increases, and by turning the control anti-
clockwise, oxidiser output decreases. Do not force the control past its stop, as this will
damage the unit and void the warranty.
3. High Salt Light
This light is a red warning indicator and will illuminate when the swimming pool
salinity level is above 4,000ppm. If this light is on, together with the ten output LEDs
(1 in Fig. 3), the salinity level is higher than necessary. However, no action is required; the
salinity level will gradually reduce from rain and splash out over time.
4. Polarity Light
The Polarity Light is the first indicator light, 10% in the Oxidiser Output array (1 in Fig. 3).
This light will alternate between orange and green every reversing cycle (4-12 hours).
The factory setting is a 12-hour cycle.
5. Digital Timer
The Digital Timer is a 24-hour, 7 day time switch for controlling the Oxidiser and
associated circulation pump ON/OFF times.

Setting the Digital Timer
To set the Oxidiser scheduled ON/OFF times, press the TIMER button. The first ON
time (1ON) will appear on the screen. The Digital Timer has 15 inbuilt daily program
settings. Press the DAY button to scroll through these programs. Generally, the every-
day program should be selected (Mo Tu We Th Fr Sa Su). This will enable the Oxidiser’s
scheduled ON/OFF times to activate every day.
Press the HOUR and MIN buttons to set the ON time. Press the TIMER button again, the
first OFF time (1OFF) will appear on the screen. Press the HOUR and MIN buttons to set
the OFF time.
Pressing the TIMER button again will show the second ON time (2ON). Repeat the
programming procedure above to complete additional ON/OFF schedules if required.
When finished programming the schedules, press the CLOCK button to return to the
home screen. On this screen, the current timer state is shown.
To reset a timer schedule, go to the schedule by pressing the TIMER button as required,
then press and hold the TIMER button again to reset.
6. Circuit Breaker
The circuit breaker mounted on the front right-hand side of the Oxidiser is designed
to trip out in the event of a power surge or overload. When tripped, the yellow centre
button will pop out, shutting down the unit. To reset, press the yellow centre button
back in to resume normal function.
Note: Turn off the Oxidiser at the power point before attempting to reset the circuit
breaker. Should the circuit breaker continue to trip, then a local Evolution distributor
should be contacted.
7. Switch
This switch allows you to choose the timer operation mode for the Oxidiser and pool
pump. The Timer selection to the left enables the Oxidiser and pool pump to turn on
and off at the designated timer settings. The Manual selection to the right allows the
Oxidiser and pump to work continuously until the switch setting is physically changed.
The Off position in the middle will turn power off to the Oxidiser and circulation pump.

6.0 DOSAGE
6.1 The Low Salt Oxidiser is designed to work with regular pool salt or mineral blend
products to sanitise the pool effectively, but it works best as a complete system
with high-quality Pure Minerals Ultra Blend™. Using Pure Minerals Ultra Blend™ will
produce a magnesium-rich and precisely sanitised pool with minimal maintenance.
6.2 The Low Salt Oxidiser operates within a salinity range of 1,800 – 4,000ppm.
The pool water salinity level must be known to begin using Pure Minerals Ultra
Blend™, and the Low Salt Oxidiser. A pool care professional can perform this
test. Once the salinity level is known, add the appropriate Pure Minerals Ultra
Blend™ amount by following the dosage tables. Dosage tables are available at
www.evolutionwls.com.au/product/pure-minerals-ultra-blend/
6.3 The dosage table for a 2,000ppm target salinity is provided as a guide on the next page
6.4 It is essential to maintain the pool water salinity within the range of 1,800 – 4,000ppm.
If the salinity falls below 1,500ppm, the unit will go into the ultra-low salinity cutout
mode (LED 1 flashing green). There is no oxidiser output in this mode, and the salinity
must be increased for the Oxidiser to return to regular operation.
6.5 Note: Before adding minerals and salt to the swimming pool, please ensure the
Oxidiser is switched off to avoid overload damage. FAILURE TO DO SO MAY VOID THE
WARRANTY.
7.0 ADDING PURE MINERALS ULTRA BLEND™
7.1 1. Ensure pool water is correctly balanced before adding Pure Minerals Ultra Blend™.
Free chlorine level must be between 1.5 and 3.0ppm, pH level must be between 7.2 and
7.6.
2. Add the recommended amount of Pure Minerals Ultra Blend™ into the shallow end
of the pool and allow to dissolve (sweep in with a broom if required).
3. Run the filter pump for 8 hours (with Oxidiser turned off) to allow for complete
dilution.
4. You may swim in the pool at any time during this process.
7.2 Note: As magnesium dissolves into the water, the water may sometimes take on
a green tinge. This is a natural effect of the magnesium, and the water colour will
return to normal after 48-72 hours.

8.0 MAINTENANCE
8.1 It is recommended that a pool water sample is taken to a pool shop and tested once per
month for analysis. Please refer to Section 2.0, 6.0 and 7.0 for additional information.
8.2 The Low Salt Oxidiser cell operates most efficiently when it is clean. As a natural result
of the electrolytic process, calcium is attracted to the titanium plates in the cell. The
self-cleaning feature helps to inhibit such build-up and scaling. However, the attraction
of calcium and other minerals is inevitable, and eventually, it must be removed by
manual cleaning.
8.3 The transparent housing of the cell allows easy visual inspections, and with correct
water chemistry, the cell will only need cleaning approximately every 3-6 months. In
regions with hard water (high calcium levels), more frequent cleaning may be required.
8.4 To clean the cell follow these instructions:
1. Turn off power to the Oxidiser and pump.
2. Remove the cell from the cell housing by loosening the cell collar and pulling the
cell out of the housing. If required, disconnect the cell cable wires at the junction box
underneath the power pack (these must be reconnected firmly and tightly).
3. With the cell removed, use a high-pressure hose nozzle to spray off as much loose
scale as possible. Do not use any sharp or metallic objects to remove scale, as this will
damage the cell.
4. If further cleaning is required, the cell needs to be cleaned in a mixture of 1 part
Hydrochloric Acid to 10 parts water. Mix the acid solution in a bucket or tube that will
fit the cell.
5. iWARNING: Chemical Hazard - When mixing acid with water, always add the
acid to the water, never add water to the acid. When using the acid, ensure to use
rubber gloves and appropriate eye protection and follow safety directions on the
Hydrochloric Acid label.
6. Place the cell into the cleaning solution submerging the plates and ensuring that
the cell head (Section 3.0 Fig. 2) does not contact the acid solution. Once the cell is
clean, remove it from the cleaning solution and rinse. Replace the cell into the housing
in the reverse manner to the steps above.
8.5 Only qualified electrical technicians should service the power pack. For the nearest
Evolution recommended service technician, please contact Evolution Water & Lighting
Solutions on 07 5565 0000 or email us at [e-mail].
