Installation & Startup

Congratulations on your recent purchase of your Neptune NDC or Pool Pro MineralX Chlorinator. Thank you for supporting Pool Pro Products.

Please take a moment to read through the entire NDC manual or MineralX 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. Pool Pro reserves the right to change the specifications of the hardware and software described herein at any time without prior notice.

Please remember that your Neptune/MineralX 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 NDC and MineralX 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 NDC or Pool Pro MineralX Digital Chlorinator. We wish you many happy years of swimming in your crystal-clear pool.

This manual contains important information about the installation, operation, and safe use of this product. This information should be given to the owner and/or operator of this equipment. When installing and using this electrical equipment, basic safety precautions should always be followed. Failure to follow safety warnings and instructions in this manual can result in serious injury and/or damage to your equipment. Read and follow all warning notices and instructions which are included in this manual.

• The Power Supply internally contains live components. There is a danger of electric shock if opened. If the power cord is damaged then it should be replaced by the manufacturer, their agent or similar.
• To reduce the risk of injury, do not permit young children to use this product unless they have been trained by the person responsible for their safety and they acknowledge their ability to use such equipment. To reduce the risk of accidents or incidents, service on the unit should only be performed by your local pool Professional.
• When mixing acid with water, ALWAYS ADD ACID TO WATER. NEVER ADD WATER TO ACID.
• DO NOT PLUG UNIT IN IF CARTON HAS BEEN WET.
• GAS BUILDUP CAN OCCUR WITH IMPROPER WIRING: To reduce the risk of 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 flowing through the unit.
• Read and keep your NDC manual or MineralX manual in a safe place.
• Increase chlorine production when temperature goes up.
• Use Stabiliser to stabilise chlorine in the swimming pool.
• Ideal salt levels for Neptune NDC models range between 3000-4000ppm, Ideally 3500ppm (parts per million). Salt levels below 3000ppm and above 4000ppm may damage equipment and void any warranty.
• Ideal salt level for Pool Pro MineralX models is 1500ppm for optimum performance.
• Decrease production when temperature goes down – see Section 12.3 WINTER/BLANKET MODE.

Your chlorinator comes with the following items:

Tools required for installation:

Check your salt levels in your pool before starting your unit. See Section 12.5 to perform a SALT TEST.

• For Neptune NDC models: 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.
• For Pool Pro MineralX models: Salt levels and mineral levels should be 1200ppm – 1800ppm (ideally 1500ppm) and no more than 2500ppm. To achieve this TDS with minerals, you may need to add 20-30% more product.
• 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 floor 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 first 8-12 hours (ensure the cell is switched off) 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.

Consult your local Pool Pro Professional to correctly balance your pool water. Follow 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 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/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 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.

• The Neptune NDC and Pool Pro MineralX Chlorinators have 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 off 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 1.5m from the Chlorinator Cell for ease of operation.

• 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.
• Refer to the 2 diagrams on pages 10 and 11 for guidance on how to correctly install the Cell.
• 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 used 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’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.
