Installation Guide for the Madimack inverCHLOR 20 Salt and Mineral Pool Chlorinator
Choose the location: Mount the control unit on a wall near the filtration system, at least 3 metres from the pool water.
Prepare the plumbing: Install the cell housing horizontally as the final piece of equipment before the water returns to the pool.
Add salt or minerals: Ensure water balance and dissolve salt fully before powering on the unit (ideal 3000 ppm salt or 4200 ppm minerals).
Set up controls: Configure clock, pool size, mode (Auto/Manual), and salt type via the touchscreen.
Optional pH Doser: Mount separately in a ventilated area using the supplied tubing and connector

Maintenance Tips
Check salt or mineral levels monthly and top up as required.
Clean the chlorinator cell only when mineral scaling is visible.
Use diluted acid (10:1 water to acid) for safe cell cleaning.
Inspect cables, unions, and fittings regularly for corrosion or wear.
Lubricate O-rings and squeeze tubes every six months if using the pH Doser.
Replace squeeze tubes annually to ensure accurate dosing
