2. GENERAL OVERVIEW
Congratulations on your recent purchase of your Oasis CX Premium Salt & Mineral Chlorinator Please
take a moment to read through the entire manual before installing your new unit. Your chlorinator must
be installed and operated as specified.
While every effort has been made to ensure that the information contained in this guide is accurate and
complete, no liability can be accepted for any errors or omissions. OASIS AQUATICS Pty Ltd reserves
the right to change the specification of the hardware and software described herein at any time without
prior notice.
Please remember that your Oasis CX Premium Salt & Mineral Chlorinator is not designed to chemically
maintain your pool water and keep it balanced, but rather to produce chlorine from a mild salt solution
within the water. We encourage regular water testing, balancing and correction if & when required to
maintain the recommended balanced levels of your pool water. This is a vital part of a complete
maintenance program and will ensure trouble free performance as well as a healthy and sparkling clean
pool.
There is one design, comprising 6 different size models in our range:
The models available (CX15, 25, 25LS, 35, 45 and 55) are all reverse polarity units designed to
automatically change direction every 4-16hrs (depending on your setting). See 7.3 CELL CLEANING
to change the reversing times. This change of polarity causes the calcium to dislodge and keep the cell
plates clean. Please note occasional cleaning of the electrode plates may still be necessary.
Thank you again for choosing an Oasis CX Premium Salt & Mineral Chlorinator We wish you many
happy years of swimming in your crystal clear pool.

2.1 Recommendations and Helpful Hints
•Read and keep your manual in a safe place.
•Increase chlorine production when temperature goes up.
•Use stabiliser to stabilise chlorine in pool.
•Maintain your salt levels between 3000-3500ppm for optimum performance.
•1500-2000ppm for CX25LS Low Salt Model.
•Decrease production when temperature goes down - see 6.4 WINTER / BLANKET MODE.

3. POOL PREPARATION
BEFORE OPERATING YOUR OASIS CX PREMIUM SALT & MINERAL CHLORINATOR PLEASE
READ THE FOLLOWING:
Check your salt levels in your pool before starting your unit. See 6.6 to perform a SALT TEST.
Salt and mineral levels should ideally be 3000-3500ppm (1500ppm -2000ppm for CX25LS) and
no more than 5000ppm. To achieve this with minerals you will need to add approximately 20-
30% more product to the pool water. Contact your local pool Professional for further assistance.
Salt levels above 6000ppm may overload the unit and cause excessive heat and void your
warranty.
For all new pool installations please seek advice from your pool builder or your local pool
Professional before adding salt, as some new surfaces request no salt to be added when initially
completed.
NEVER ADD SALT/MINERALS DIRECTLY TO THE SKIMMER BOX. This high concentration
of either salt or minerals will pass through your filtration, pump and other pool.
HANDY TIPS
The colder the water the lower your output but this does not mean you need more salt. There
will always be less chlorine demand in colder water.
We recommend 3.5kg per 1000 litre of pool water and a 50,000lt new pool needs approximately
175kg of salt. For the FRESHWATER LOW SALT SYSTEM Model: CX25LS, we recommend
1.5kg per 1000 litre of pool water.
The unit can operate on mineral/magnesium chloride salts, and you should allow an extra 20-
30% extra product for these types of salts.
Salt should always be added to the shallow end of the pool and allowed to dissolve. DO NOT
let the salt settle on the floor of the pool as they may cause damage to the surface. Use your
pool brush to mix the salt into the water.
Running the pump will mix the water and help the salt to dissolve.
Only run the pump in the first 8 –12 hours (ensure the cell is switched off to allow the salt to
dissolve.)
By pressing (TDS TEST)a salt measurement is taken, and a total TDS reading is indicated. The
ideal TDS reading should be an LCD display of “OK”, approximately 3000-3500ppm. If "HIGH"
is displayed, the salt level is above 4500ppm and the salt level is too high, and if “LOW” is
displayed the salt is below 1000ppm and we suggest taking a sample to your local pool
Professional for a more accurate result and further assistance. For the freshwater low salt
system Model: CX25LS, the ideal or "OK" TDS reading is 1500-2000ppm.

CX Chlorinator - Salt and Mineral Operation MANUAL Page 7of 33
4. POWER PACK AND CELL INSTALLATION
4.1 Power Pack Installation
The Oasis CX Premium Salt & Mineral Chlorinator has an Ingress Protection Rating of IP23
enabling it to be installed outdoors. Regulations require that the Power Pack shall be installed
outside the pool zone. The Power Pack shall be installed according to AS/NZS 3000 wiring
rules.
The Power Pack should be installed in a well-ventilated position ideally away from sunlight and
rain to prolong life and at least 1m above ground to prevent run of water entry.
Ensure that the Power Pack is not stored near chemicals, fertilisers or in a closed unventilated
shed with similar products as the fumes will cause excessive corrosion and damage to the
internals of the Power Pack and may void warranty.
When mounting the Power Pack on a post it is recommended to install a flat panel at least the
same size to act as a waterproof backing plate.
Mount the Power Pack with the Mounting Bracket, Green Plugs and Screws provided.
The Power Pack should be mounted no further than 1.5 metres from the Chlorinator Cell for
ease of operation.
4.2 Cell Electrode Installation
Connect the Cell Housing horizontally in the return line to the pool (use reducing bushes
supplied if 40mm PVC pipe) using high pressure PVC glue. The Cell Housing can be mounted
vertically but provision must be made for a gas trap.
Direction of water flow through the Cell Housing is not critical although we do recommend entry
from the closed end of the Cell Housing and exit from the end closest to the Cell Locking Ring.
The reason is to cause less water hammer over time on the cell plates.
Check that the O-ring is clean, greased with silicone grease (DO NOT use petroleum-based
jelly) and securely located in the Cell Housing.
Ensure Cell Locking Ring is firmly tightened by hand (DO NOT use a tool to tighten).
Connect the lead from the Cell Electrode to the Cell Plug under the Power Pack ensuring a firm
snap lock connection.
Plug the Power Pack 3 pin plug into a suitable weatherproof RCD protected 10amp outlet and
then plug the pump into the 3 pin AC Socket located at the bottom of the Power Pack.

CX Chlorinator - Salt and Mineral Operation MANUAL Page 8of 33
4.3 Installation Diagram
WARNING: DO NOT plug in if carton has been wet
Important Notes:
The pump rating must not exceed 8amps.
Saltwater may damage electrical components in the Power Pack.
WARNING:
We DO NOT recommend the use of valves on the inlet or outlet of the cell housing. If you do use a
valve, then it is important to ensure that the valve cannot deadhead (lock closed) while the pump is
running. It is the installers responsibility to ensure some form of flow control is installed in this instance,
and it disables the pump.
ALWAYS ensure that pipe work and equipment DO NOT allow gases generated from the cell to collect
and build up in any part of the installation.
It is RECOMMENDED that the Cell Housing be installed horizontally to create a natural gas trap that
acts as a safety device. Installation in any other way may cause explosion, injury or death if the installer
does not allow for gas removal. A venturi pipe is installed/moulded within the Cell Housing design to
eliminate any possible gas build up, although it is always recommended to ensure proper installation to
eliminate this from happening.
The Cell Housing must be installed in the RETURN pipework to the pool. It must always be installed
after the filter, gas heater, solar heating, or heat pump.
DO NOT apply priming fluid to the cell Housing, it is not needed and may react with the plastic.

6.6 SALT TEST
BEFORE ENTERING SALT TEST YOU MUST BE IN THE DDS SCREEN.
[ TDS TEST] button measures the salt level in your swimming pool. A reading will appear on the screen,
allow at least 30 seconds for an accurate reading.
BEFORE PERFORMING A SALT TEST, ENSURE THE CELL IS CLEAR OF ANY CALCIUM
DEPOSITS, AS THIS WILL INSULATE THE ELECTRODES AND IMPACT YOUR READINGS.
See 9.1 Inspecting and Cleaning the Cell Electrode if manual cleaning is required.
The Salt level is tested and displayed as shown to the right.
By pressing (TDS TEST) a salt measurement is taken, and a total TDS
reading is indicated. The ideal TDS reading should be “OK”, approximately
3000-3500ppm.
If "HIGH" is displayed, the salt level is above 4500ppm and the salt level is
too high, and we suggest taking a sample to your local pool Professional for
a more accurate result and further assistance.
Similarly, if the display indicates "LOW" take a sample of pool water to your
pool Professional for more accurate results and advice. For the freshwater
low salt system Model: CX25LS, the ideal or "OK" TDS reading is 1500-
2000ppm.
Low salt levels (below 1000ppm) and high salt levels (above 8000ppm) are difficult to measure and
results may become inaccurate. It may be that your cell needs replacing, contact your local pool
Professional for a more accurate result and further assistance.
The SALT TEST measurement is meant to be a guide only as many factors can impact the result. We
recommend you take your pool water sample to your local pool Professional before adding salt/minerals
or replacing your Cell.
NEVER add more salt if not required. NEVER add salt directly in the skimmer box.
SALT TEST can also be entered by pressing the [OK] button in MAIN MENU and scrolling to SALT

8. WATER CHEMISTRY
The Oasis CX Premium Salt & Mineral Chlorinator unit is designed for use with swimming pool water
balanced in accordance with the Langelier Saturation Index with a pH range of 6.8-7.8.
As previously advised, for best performance and operation of your Oasis CX Premium Salt &
Mineral Chlorinator unit, certain water balances must be maintained within your swimming pool.
Have your water tested regularly. Transport the test water in an opaque container and have the
test done as soon as possible as possible for best results.
8.1 Chlorine
Measurement Interval: Once a week
Ideal Chlorine (Free Chlorine) Levels: 2-3ppm (2-3mg/L) and no more than 4ppm (4mg/L).Adjust the
chlorine output by pressing [+] in DDS to increase the required output set point in 1% increments up to
100%. Pressing [-] will decrease the output in 1% increments to 0%. Running the unit for longer or
shorter hours can achieve the same result.
8.2 Salt
Measurement Interval: Every 4-6 weeks
Ideal Salt Levels: 3000-3500ppm and no more than 4000ppm.
For the FRESHWATER LOW SALT SYSTEM Model: VP25LS, the ideal TDS reading is 1500-
2000ppm.
Although salt is not consumed by the Chlorinator, salt is lost during backwashing, pool overflow,
splashing and on bathers that use it. The correct salt level allows for themost efficient production levels
and electricity consumption.
The salt level SHOULD NOT go below 3000ppm or 1500ppm for the CX25LS model. Operating theunit
with too little salt in the pool will cause damage to your Cell.
Salt is the essential element by which your unit operates. Not enough salt means not enough chlorine
- this simple rule governs the total operation of your Oasis CX Premium Salt & Mineral Chlorinator unit,
and insufficient salt will damage, your Cell. Use ultrafine Salt or premium Salt to keep optimum salt
levels. The unit will operate with good stability on higher salt levels but it is still advisable to run at the
correct level to prevent damage. Salt levels above 4000ppm or 2500ppm in the CX25LS model may
overload the unit and cause excessive heat.
NEVER ADD SALT DIRECTLY TO THE SKIMMER BOX.
This high concentration of salt will pass through your filtration, pump and other pool equipment.
HANDY TIP: The colder the water the lower your output but this does not mean you need more salt.
There will always be less chlorine demand in colder water.
We recommend 3.5kg per 1000 litres of pool water and a 50,000lt new pool needs approximately 175kg
of salt. For the FRESHWATER LOW SALT SYSTEM Model: CX25LS, we recommend 1.5kg per 1000
litre of pool water.
The unit can operate on mineral/magnesium chloride salts and you should allow an extra 20-30% more
product for these type of salts. Salt should always be added to the shallow end of the pool and allowed
to dissolve. DO NOT let the salt settle on the floor of the pool as thismay cause damage to the surface.
Use your pool brush to mix the salt into the water.
Running the pump will mix the water and help the salt to dissolve.
Low salt levels (<1000ppm) will destroy the coating on the Cell and void the warranty.
