Zodiac – Ei² iQ pH 20 Evo Salt Chlorinator – 20 g/h

The Zodiac Ei² iQ pH 20 Evo is a salt chlorinator with chlorine production of 20 g/h, for pools up to 90 m³. It includes pH control with an embedded pH pump as standard and works at a recommended salt level of 4 g/L (3,5 – 10 g/L).

How salt water chlorination works

The Ei² iQ pH Evo range consists of an electrolysis cell and a control unit. Salt is dissolved in the pool water, and when the salt solution passes through the titanium plates (electrodes) in the cell, an electric current produces free chlorine.

The chlorinator produces chlorine while the pool’s filtration system (pump and filter) is running. The recommended salinity is 4 g/L, within an operating range of 3,5 – 10 g/L. The cell’s electrodes are cleaned automatically, which prevents incrustations from forming on them.

The large user interface is black with a white information ring and touch buttons. It focuses on essential information, while all setting details can be reached through the touch buttons.

Bluetooth and Wi-Fi are embedded, so the unit can be controlled remotely with the manufacturer’s app. Boost mode gives 100% chlorination for 24 hours, and cover mode reduces chlorination, with adjustable settings, while the pool cover is closed.

PH and ORP regulation

As an Evo version, the range includes pH regulation as standard, with an embedded pH pump and a high quality glass sensor. Redox (ORP) regulation can be added with the optional ORP kit, which uses a high quality gold glass sensor.

The control unit also reads water salinity and temperature. A mechanical flow switch stops chlorine production automatically if there is no flow in the cell.

Cell and installation

The patented Quick Fix cell fits 50 and 63 mm pipes and has high quality titanium plates. Its translucent body makes it easy to check the polarity-reversing electrode. The pack includes the cell installation kit, flow switch kit, wall mounting kit and temperature sensor kit.

The control unit runs from a 230 Vac supply. Mount it upright on a rigid surface in a dry, ventilated area, protected from the weather and never where there is a risk of flooding. The cell goes in a horizontal pipe, following the direction of water flow.

Installation, electrical connection and maintenance are work for a qualified installer, who should follow the full manual from the manufacturer.

Start-up and maintenance

Before starting, the filter should be clean, the water balanced and free of copper, iron and algae, and any pool heating equipment must be compatible with salt in the water. The salt should be fully dissolved, with the filter pump running, before the chlorinator is switched on.

The control unit shows alarms and troubleshooting messages for flow, salt level, temperature, pH and cell condition. The cell and the pH pump need periodic maintenance, and the pH and ORP sensors need calibration. Details are in the manufacturer’s full manual.
