1. IMPORTANT WARNINGS/SAFETY INSTRUCTIONS
Congratulations on your recent purchase of your Neptune Digital Salt and Mineral
Chlorinator. Thank you for supporting Pool Pro Products.
Please take a moment to read through the entire manual before installing your new
unit.Yourchlorinatormustbeinstalledandoperatedasspecied.Whileeverye󰀨ort
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. Pool Pro reserves
therighttochangethespecicationsofthehardwareandsoftwaredescribedhereinat
any time without prior notice.
Please remember that your Neptune 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, and 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.
The Neptune Digital Chlorinator models are reverse polarity units designed to
automatically change direction every 4-16 hours (depending on your setting). This
change of polarity causes the calcium to dislodge and keep the cell plates clean.
Occasional cleaning of the electrode plates may still be necessary.
Thank you again for choosing a Neptune Digital Chlorinator. We wish you many happy
years of swimming in your crystal-clear pool.

personal injury the Power Pack is designed so that the Electrolytic Cell will only
receive power when the pool pump is on. Otherwise, dangerous chlorine gas
build-up can occur. If the pump is not installed to the AC Socket (pump outlet) on
the Power Pack, then the installer must ensure that the Electrolytic Cell is never
energizedwhenthepoolpumpisOFF,orwaterisnotowingthroughtheunit.
●Read and keep your user manual in a safe place.
●Increase chlorine production when temperature goes up.
●Use Stabiliser to stabilise chlorine in the swimming pool.
●Ideal salt levels range between 3000-3500ppm (parts per million). Salt levels below
3000ppm and above 4000ppm may damage equipment and void any warranty.
●Decrease production when temperature goes down - see Section 12.3 WINTER/
BLANKET MODE.

4. PREPARING THE POOL
Check your salt levels in your pool before starting your unit. See Section 12.5 to
perform a SALT TEST.
Salt levels should be 3000-4000ppm (ideally 3500ppm). Salt levels below
3000ppm and above 4500ppm may damage equipment and void any warranty. To
achieve this TDS with minerals, you may need to add 20-30% more product to the
pool water. Contact your local pool Professional for further assistance.
Salt levels above 5000ppm on these models 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 equipment. Remove automatic pool cleaner from the pool before
adding salt or other chemicals.
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.
For salt only: We recommend adding 3.5kg of pool salt per 1000 litres of pool water.
For minerals/magnesium chloride: Allow an extra 20-30% of the product to achieve
the correct TDS for these types of salts. Follow the instructions on the product
packaging and/or consult your local pool Professional.
Salt and minerals should always be added to the shallow end of the pool and allowed
todissolve.Donotletthesalt/mineralssettleontheoorofthepoolasitmaycause
damage to the surface. Use your pool brush to mix the salt/minerals into the water.
Running the pump will mix the water and help the salt/minerals to dissolve.
Onlyrunthepumpintherst8-12hours(ensurethecellisswitchedo󰀨)toallowthe
salt/minerals to dissolve.
By pressing [SALT TEST] a salt measurement is taken, and a total TDS reading is
displayed. The ideal TDS reading should be an LCD display of “OK”, approximately
3000ppm – 4000ppm. 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.

instructions on the packaging of each chemical. Always add chemicals to water, never
add water to chemicals.

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installer’sresponsibilitytoensuresomeformofow
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/
molded 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lter,gasheater,solarheating,orheatpump.
DONOTapplypriminguidtotheCellHousing,itisnotneededandmayreactwiththe

7. INSTALLING THE CHLORINATOR POWER PACK
The Neptune Digital Salt and 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o󰀨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at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 1.5m from the Chlorinator Cell for
ease of operation.
8. INSTALLING THE CELL
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ow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rmlytightenedbyhand(DONOTusedatooltotighten).
Connect the lead from the Cell Electrode to the Cell Plug under the Power Pack
ensuringarmsnaplockconnection.
Plug the Power Pack’s 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.

menu. Press to select pH Control Mode.

Page 18 www.poolpro.com.au
2. Press or to adjust the setting between ON or OFF, then press to save.
To set the run time of the pH Controller:
The run time is programmed automatically when setting up the volume of the swimming
pool in the chlorinator. The system calculates how many minutes per day your Neptune
pH Controller runs based on the volume of your pool. This can be changed manually.
1. “RunTime”willash.Press to enter the Run Time settings. To adjust the run
time press or then press to save (and return to the Main Screen) or
press to exit without saving.
NOTE: Some states use undiluted acid to feed the pH Controller (i.e. there is no
container with a 1:3 mix). In this case the operator needs to manually change the run
time from the displayed result to an approximate 1/4 of this reading. For example if
15min/day is displayed then change this to 4min/day.
To set the demand or prime quantity of the pH Controller:
The demand or prime quantity can be manually adjusted from 0-5000ml. This function
is useful for priming tubes after an acid drum change, or adding the required acid from
your acid demand test.
IMPORTANT: Enter the exact amount from your test result in ml (e.g. 500ml) and the
system automatically adds 4 times that amount, thereby allowing for the
1:3 ACID:WATER mix ratio in the acid drum.
If you are now back in the Main Screen, go back into the pH Control Mode:
1. Press the button to enter the Main Menu. Press or to scroll through the
menu. Press to select pH Control Mode. Press or to scroll to Demand
or Prime and press .
2. Press or to adjust the ml quantity then press to save. The peristaltic
pumpstartsturningandatime-basedreadingstartsashingandcountingdown.If
desired, you can lower the time by pressing then pressing toconrm.
3. If the tubes/lines are primed, you can stop the peristaltic pump by pressing
while in the DOSE TIME LEFT menu, until the time left reaches 0, then press to
conrm.Press to return to the Main Screen.

General Maintenance
1. Never cover the chlorinator unit with towels or similar. The chlorinator has air vents
to keep it cool. Covering the vents may cause damage to the chlorinator.
2. The chlorinator should always be in an undercover area away from the elements.
3. The chlorinator should never be in a closed shed or similar environment near
chemicals or fertilisers. Fumes from chemicals and fertilisers may cause damage to
the chlorinator and may void the warranty.
4. Annually check all plug connections are tight and in sound condition.
Cell Maintenance
The cell may require cleaning if it contains debris or is being used in an area with hard
water. Hard water can cause calcium build-up on the cell, the sensor, or the cell plates.
1. Press the button to OFF.
2. Switcho󰀨thechlorinatorandunplugatthepowerpoint.
3. Unscrew the cell’s locking ring and remove the cell’s electrode.
4. Check for pool debris, especially after backwashing. Check for calcium build-up on
the electrode. Do not scratch or bend the cell plates.
5. If calcium build-up is present, use Pool Pro Cell Cleaner to clean the cell. We do
not recommend the use of Hydrochloric Acid to clean the cell.
6. Check the cell’s O-Ring is clean, greased with silicone grease (never use
petroleum based lubricants) and securely located in the cell housing.
7. Reinstall the cell into the housing and hand tighten the locking ring securely.
8. Plug the chlorinator into the power point and press the button to turn the
chlorinator on. The chlorinator will return to its previous settings.
Power Pack Maintenance
1. Ensure the chlorinator is plugged into a weatherproof RCD protected 10amp outlet.
2. Ensure the pool pump is plugged into the bottom AC socket of the chlorinator unit.
3. Check all plugs and cords for damage. If any are damaged, they must be replaced
bythemanufacturerorasimilarqualiedperson.Ifthechlorinatorishardwired,a
qualiedelectricianisrequired.
4. Periodicallyturnthechlorinatoro󰀨andapplyaninsectsurfacesprayontheWALL
or POST that the chlorinator is mounted to, to keep insects from entering the
chlorinator unit. DO NOT spray directly into the air vents or on the chlorinator unit.
Allow adequate time for the spray to dry, before turning the chlorinator back on.
