ChloroMatic ® ESC-pH SYSTEM
The ESC-pH unit is a combination of the ESC Chlorinator and a pH Controller. Please refer to the relevant chapter
in this Manual for information on how to operate the chlorinator. It should be noted that there are minor differences
in chlorinator operation as compared with the standard ESC system described in this Manual. The Chloromatic
ESCpH unit does not display the output control setting or include run dry pump protection.
The pH Control system functions are located on the Chloromatic instrument panel in the dark-coloured area
marked “pH CONTROL”.
LED DIGITAL DISPLAY
■ The digital display is used to provide information on the chlorinator output, pH and pH set point.
■ The display will alternately show the chlorine production and pH
■ When the pH Control switch is placed in the SET position the display will show the pH set point
FEED & pH STATUS LEDs
The pH STATUS LED is used to indicate if the pH is within a range of ±0.3pH of the set point. If the pH is more
than 0.3pH above the set point the LED will flash red/green. If the pH is less than 0.3pH below the set point the
LED will flash red.
The FEED STATUS LED is used to indicate the operation of the acid dosing pump:
RED ACID PUMP OFF
GREEN ACID PUMP AVAILABLE
GREEN FLASHING ACID PUMP DOSING
pH CONTROL
The control switch has three positions:
■ RUN – In this position the acid dosing pump will operate according to the value of the pH set point and
measured pH
■ SET – This will allow adjustment of the controller set point using adjustment tool. Turn clockwise to
increase the set point. Note that acid pump is off when adjusting set point
■ OFF – Disables the acid dosing pump and control functions
IMPORTANT NOTES:
1. The ChloroMatic guarantee does not apply to commercial or semi-commercial installations, i.e. where
the system runs more than an average of 8 hours per day over the year. Guarantee on commercial and
semi-commercial installations is 12 months only on both power supply and cells.
2. ALWAYS INSIST ON GENUINE CHLOROMATIC REPLACEMENT PARTS. If it is necessary to replace the
Electrolytic Cell, beware of “look alikes”. Only the Genuine ChloroMatic Cell is designed and warranted to
operate with the ChloroMatic Power Supply.
SERIOUS DAMAGE MAY RESULT TO THE ELECTRONICS INSIDE THE UNIT IF COPY ELECTRODES ARE
USED AND WILL VOID WARRANTY.
