AstralPool – E-Next pH 12 Salt Chlorinator – 12 g/h

The AstralPool E-Next pH 12 is a salt chlorinator with built-in pH control, producing 12 g/h of chlorine for pools up to 50 m3. It runs on 230 V ac 50/60 Hz and draws 0.4 A.

How the system works

The E-Next pH range consists of an electrolysis cell and a power supply. Salt is dissolved in the pool water, and as this salty water passes through the cell, an electric current across the titanium plates (electrodes) produces free chlorine.

Chlorine is produced whenever the pool circulation system (pump and filter) is running. The recommended salt level is 5 – 6 g/l, with an operating range of 5 – 12 g/l.

The electrodes clean themselves automatically through polarity reversal, which helps prevent scale forming on them.

PH control and dosing

Unlike the standard E-Next, the pH versions include a built-in pH controller. It shows the measured pH value and the setpoint on the display, and the setpoint is set with a dedicated key on the front panel.

The pH controller switches a dosing pump to correct the water. The peristaltic dosing pump has a constant flow of 1.5 l/h at 1.5 bar and runs on 230 V. The pH sensor is calibrated automatically using calibration solutions.

Separate indicators warn of low and high pH readings.

Alarms and production control

The front panel offers several functions and warnings:

• Flow alarm, shown by all LEDs blinking
• Salinity alarm for low or high salt levels, which helps protect the cell
• pH alarm indicators for low and high values
• Production level selection key with a percentage scale
• Cover input that reduces chlorine production when the pool has an automatic cover (potential-free contact)

Installation and safety

Installation and electrical connection must be carried out by a qualified installer, following the current electrical and accident prevention regulations. The unit runs on 230 V ac 50/60 Hz and must not be altered to run on another voltage.

The equipment must be earthed and fed from a residual current device. A disconnector switch is required for the electrical connection. Disconnect the equipment from the mains before installing or replacing any component.

The power supply has IP24 protection and should not be installed where flooding can occur. As it produces heat, it needs a well-ventilated location, away from flammable materials. The cell has a maximum pressure of 1 Kg/cm2 and a working temperature of 15 – 40ºC max.

Maintenance

The electrolysis cell has a transparent body, so its condition can be checked easily. The pH sensor needs periodic calibration using the calibration solutions, either in fast or standard mode as described in the instruction manual.

Use only spare parts supplied by the manufacturer. If the power cable is damaged, it must be replaced by the manufacturer, its after-sales service or similarly qualified personnel.
