- Page 9 ELECTRICAL CONNECTIONS The EF300 unit is supplied internally prewired and complete with power cable. Standard power supply: 230 V∼, 50 Hz, monophasic. Carefully follow all the rules of electrical safety. Before starting the unit, check that all electrical and plumbing connections have been properly executed.
- Page 10 Internal Connections (for technical personnel only) The unit is provided internally prewired, and all connections of normal use (power supply, dosing pumps, measurement sensors and flow sensor) are available externally via cable or connector. However, if you need to operate on the electronic boards or replace blown fuses, refer to the diagram below.
- Page 11 START-UP At start-up the microcontroller displays for a couple of seconds information about the firmware (type / version), then shows the two measures flashing for all the start-up delay time (if set) and then starts operating accordingly with the configured working mode. VISUALIZATIONS During normal operations, the display shows the two measured values on the top line, while the bottom row switches between the temperature measurement and the status of the two pumps.
- Page 12 Standard Configuration The standard configuration mode allows the customer to set a series of parameters related to the normal functioning of the unit. These parameters can be freely accessed and configured from the front keyboard. Once selected the “Standard Configuration” S T A N D A R D C O N F I G .

- Page 14 measurement returns to an acceptable. If measurement remains outside of the setpoint for a time longer than that set, an alarm is generated, the display shows the message “Al.1” and the pump stops dosing. To reset the alarm and resume to normal operations, press the ON/OFF button or shutdown and restart the unit.
- Page 15 Notes: • Once in configuration mode, if no button is pressed for 30 seconds, the unit automatically returns to the idle mode. • The system is factory configured with default values; you can delete undesired settings and restore the initial configuration, using the “AUTOSET” function (P15). Electrochemical Calibration pH Calibration Rinse the pH electrode with distilled water, then immerse it in the pH 7.01 pH buffer solution.
- Page 16 Calibration of the CAC-CLO-M1 Cell To calibrate the cell, a colorimeter for measuring the chlorine concentration in aqueous solutions is needed (for example with DPD1 method). Run instrument and cell for at least 6 hours with chlorinated water, containing an average chlorine working concentration.
- Page 17 Manual Mode At any time, you can force a manual working mode, useful for a temporary use of the system. If a password has been set (see parameter P16), the system will require it to enable the access to this feature.
- Page 18 CAC-CLO-M1 CELL The supplied cell measures the organic free chlorine concentration in water and is provided complete with a spare electrolyte bottle. The CAC-CLO cells are membrane covered, amperometric, 2-electrode sensors, with the electrodes immersed in a specific electrolyte. They allow to determine the concentration in water of available chlorine.
- Page 19 Legend Electrolyte bottle Membrane-cap Nozzle Vent hole L. Electrolyte filling level Important Notes To avoid measurement errors, the membrane-cap must be correctly screwed till the stop (see picture). The electrolyte easily oxidizes with air. After use, always keep the bottle closed. Do not transfer to other containers.
