Madimack InverCHLOR MC400 Salt Chlorine Generator, 40,000 Gallons | MC400NA

Key Benefits + Salt System Compatibility

• Manufacturer sizing of up to 40,000 gallons identifies the MC400 option in the InverCHLOR range.
• Generates chlorine from salt in the pool water to support an ongoing sanitizing routine.
• Inverter output control lets the system adjust production according to its selected operating settings.

• Wi-Fi connectivity and on-unit controls provide access to system settings and status.

Quick Product Summary

The Madimack InverCHLOR MC400 salt chlorine generator, SKU MC400NA, is a pool sanitizing system with a manufacturer rating for pools up to 40,000 gallons. It suits a professionally planned salt-system installation or replacement where the controller, cell, plumbing and electrical requirements have been checked. Match this exact model and SKU before ordering; pool volume, climate and chlorine demand all matter when selecting capacity.

Best For

Owners of permanently installed pools evaluating an InverCHLOR system in the up-to-40,000-gallon class. A pool operating near a system’s maximum volume may need a separate review of sunlight, swimming load and circulation hours before a final selection is made.

Why This Matters

• A salt system produces chlorine; it does not make a chlorine-free pool. Understanding that distinction helps you continue the water testing and balancing needed for effective sanitation.
• Selecting by exact controller and cell version helps prevent wrong-part orders. Similar product names do not establish interchangeability with newer or older InverCHLOR versions.
• Salt concentration, operating time and pool conditions affect chlorine production. A capacity label should support an equipment assessment rather than replace one.

Common Signs You Need This / Use This When

• You are converting a suitable, permanently installed pool to a salt chlorination routine.
• Your existing salt system needs replacement following a diagnosis of the controller, cell and water conditions.
• You want to compare inverter control and remote settings while retaining a regular testing and maintenance schedule.

Compatibility / Fitment Notes

Use MC400NA as the ordering reference and confirm the supplied controller and cell match the MC400 system. Do not assume that another InverCHLOR SKU is identical because its pool-volume rating is similar.

The published 1.5- and 2-inch connection options do not confirm a direct swap into every equipment pad. Have an installer verify cell orientation, plumbing arrangement, required flow and the electrical installation using the manual for this exact version.

Check the pool surface and all connected equipment for suitability for saltwater operation. If you want acid dosing or coordination with other equipment, confirm the required accessories and connections before purchase. The acid feeder is a separate product and should not be assumed to be included with this salt-system listing.

Installation / Use Notes

Have a qualified pool-equipment professional install and commission the system according to the model-specific manual and Madimack’s warranty requirements. Establish balanced water chemistry and verify salinity with suitable testing before the installer sets the operating schedule.

Continue testing free chlorine, pH and salt concentration, adjusting the maintenance routine as conditions change. Inspect the cell as instructed and follow the manufacturer’s cleaning guidance; reverse polarity does not eliminate maintenance or water-balance requirements.

Frequently Asked Questions

What pool size is the InverCHLOR MC400 rated for?

Madimack lists up to 40,000 gallons for MC400NA. Have a professional evaluate chlorine demand, climate, swimming load and operating time before relying on the maximum pool-volume rating.

Does a salt chlorine generator remove the need for chlorine testing?

No. The cell produces chlorine from salt, so free-chlorine testing remains necessary. Continue checking pH, salinity and the other water-balance values recommended for your pool.

Will this replace another brand of salt system?

A replacement may require changes to the controller, cell plumbing, connections and electrical installation. Confirm the complete installation requirements; no universal drop-in fit is implied.

Is the InverCHLOR acid feeder included?

The acid feeder is a separate optional product. It can support dosing through a compatible InverCHLOR system, but its requirements and package contents should be confirmed separately.

What warranty is listed for InverCHLOR?

Madimack’s U.S. schedule lists four years for parts and one year for on-site labor, subject to the full limited-warranty terms. Benchmark Pool Supply is a certified Madimack online dealer.
