How It Works
The INSNRG Ni 40 transforms salt or minerals (like magnesium or potassium) dissolved in your pool water into chlorine through electrolysis. As water passes through the self-cleaning cell, chlorine is produced to instantly kill algae and bacteria, while a residual sanitizer level remains in the pool to continuously eliminate contaminants. The inbuilt timer and output control let you set operating hours and power levels to match your pool’s size and environmental conditions. When paired with the INSNRG Qi Variable Speed Pump, you can alternate between high-flow circulation and energy-saving low speeds. The Ni 40 also features a backwash mode that stops chlorine production during filter cleaning, preventing excess gas buildup for added safety.
Installation Requirements:
- Glue the cell in-line after the heater, filter, and solar (if installed), ensuring vertical installation.
- Mount the controller 1.2m above ground, preferably out of direct sunlight.
- Maintain salt level between 3,500–4,000 ppm (minimum 2,000 ppm) using approximately 280–320 kg of salt for an 80,000 L pool.
- When adding salt, pour into the pool and brush in; run the chlorinator and filter pump while dissolving, and never pour salt into the skimmer box.

Pool Chemistry Guidelines
For optimal performance of your INSNRG Ni 40, maintaining proper water chemistry is essential. These levels may vary by location, so we strongly advise consulting a local pool professional to ensure your pool is correctly set up. The chart below offers guidelines to enhance performance and extend equipment lifespan. Deviating from these ranges may harm your chlorinator and its effectiveness.
| Important Pool Chemistry Levels |
Range |
| pH |
7.0 to 7.4 (fibreglass pools), 7.2 to 7.8 (other pools) |
| Total Alkalinity |
80 to 120 ppm |
| Total Chlorine |
1.5 to 3.0 ppm |
| Stabiliser (Cyanuric Acid) |
20 to 30 ppm |
| Calcium Hardness |
200 to 250 ppm |
| Salt Level |
3,500 to 4,000 ppm (minimum 2,000 ppm) |
Operating Tips:
- Summer: Run for 8–12 hours daily (e.g., 8 AM–1 PM and 4 PM–9 PM) at 100% output. Extend in extreme heat if chlorine levels drop.
- Winter: Run for 5–6 hours daily at 60–80% output.
- Chlorine Check: Test after the morning run; adjust output to maintain 1.5–3 ppm free chlorine.
- Salt Maintenance: Test salinity annually; add salt as needed, ensuring it never falls below 2,000 ppm. If voltage is below 14V, reduce salt; if above 20V, add more salt.
Frequently Asked Questions:
How often should I run the Ni 40 chlorinator?
From spring to autumn, run for 8–12 hours daily at 100% output; in winter, 5–6 hours at 60–80% output. Adjust based on chlorine levels and environmental conditions.
What salt or mineral levels does the Ni 40 require?
Maintain between 3,500–4,000 ppm (minimum 2,000 ppm). It supports salt or mineral blends (e.g., magnesium) to suit your pool’s needs.
What does “Dry Cell Detected” mean?
It indicates zero or low water flow through the cell. Ensure the pump basket is full, the pump is running, and all leaf baskets and filters are clean.
How long does the chlorinator cell last?
With proper maintenance, the cell can last 5 years or more, backed by a 5-year warranty. The self-cleaning feature reduces calcium buildup, extending its life.
Is the Ni 40 suitable for my pool?
Ideal for pools up to 80,000 L (temperate climates, ave 15°C) or 70,000 L (tropical climates, ave 20°C), delivering consistent sanitization for clean, safe swimming. For help choosing a pool chlorinator click here.
What’s covered by the warranty?
3-year warranty on the power pack, 5-year warranty on the cell. Refer to the manual or contact us for details.
How often should I test my pool water chemistry?
Test weekly during pool use, and monthly in winter if the pool is not in use. Check salt levels annually.
Will I need to clean the chlorinator cell?
The intelligent variable reverse polarity algorithm minimizes manual cleaning by reducing calcium and debris buildup, making maintenance nearly effortless.
Can the Ni 40 work with variable speed pumps?
Yes, it integrates with the INSNRG Qi Variable Speed Pump, allowing flexible pump speeds for optimal circulation and energy savings.
How do I adjust chlorine output on the Ni 40?
Use the up or down buttons to adjust output in 20% increments. Monitor chlorine levels (1.5–3 ppm) and adjust gradually over several days if needed.
Why is maintaining pool water chemistry important for the Ni 40?
Proper chemistry ensures optimal performance and extends the lifespan of your Ni 40. Deviating from recommended levels, like pH 7.0–7.8 or Total Chlorine 1.5–3.0 ppm, can damage the chlorinator and reduce its effectiveness.
Can I set up my pool chemistry myself, or do I need a professional?
While you can monitor levels like Total Alkalinity (80–120 ppm) yourself, ideal chemistry varies by location. We strongly advise consulting a local pool professional to set up your pool correctly.
What happens if my pool chemistry is outside the recommended ranges?
If levels like Stabiliser (20–30 ppm) or Salt (3,500–4,000 ppm) fall outside the suggested ranges, it may harm your Ni 40’s performance, cause corrosion, or reduce sanitization efficiency.
How do I use the Backwash Menu with the Ni 40?
If you have a Sand or Media Filter installed, you will need to periodically clean your filter as per the instructions provided in the relevant manual. Your Insnrg Ni 40 Chlorinator has a Backwash Menu that will assist you to ensure you get the right amount of time to clean your filter and to eliminate the risk of leaving your pump running too long and wasting your expensive pool water.
