Page 7: Hydraulic Connections
HYDRAULIC CONNECTIONS Check that the suction line does not exceed the maximum height of 1.5 m from the tank bottom. Unscrew the pipe-wrench nut and remove the two protective caps from fittings (in the case a pump head needs to be removed, it is recommended to reuse the protective caps, to prevent any leakage from the pump body). -
Page 8: Priming
PRIMING Slightly open the bleed valve and set the manual operation at the maximum dosing frequency, to facilitate priming of the pump. When the product to be dosed protrudes from the purge tube, close the valve. Sometimes it is more effective slightly loosen the bleed valve, wait 4-5 seconds, close it, wait a few seconds and repeat the operation. -

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. Connector for front board flat cable µProcesor Power... -
Page 10: Operation Of The Electronic Unit
During manual working mode, the display shows on the top line the pump to which the information refers, while the bottom row shows the pump status and working frequency. For example: “Pump 2 manual” “ON 78i/min” In these conditions, pressing the ⇓ or ⇑ button, you can respectively decrease or increase the working frequency, while the ON/OFF button allows to enable / disable the pump. -
Page 11: List Of Configuration Parameters
List of Configuration Parameters In this section are listed all the configuration parameters. It is recommended to fill the last column with the values set for your application. PAR. Description Min Value Max Value Default Value Set Value Functioning Type Pump 1 ON-OFF / Proportional ON-OFF Setpoint Pump 1... - Page 12 PARAMETER 05 WORKING FREQUENCY OF PUMP 1 If the pump is configured for ON-OFF mode, this parameter is the working frequency of the pump. If the pump is configured for proportional functioning, this parameter states the maximum working frequency of the pump (when the measurement is far from the set threshold).

Page 13: Electrochemical Calibration
Warning! The inversion of this parameter compared to the default setting can determine the functioning of the device even in the absence of flow! PARAMETER 19 pH EQUILIBRIUM This parameter allows to set a maximum waiting time before activating the chlorine adjustment, during which only the pH adjustment is active. -

Redox Calibration 1) Rinse the electrode with distilled water, then immerse it in the calibration solution (e.g. 220 mV) 2) Press the CAL key to enter the menu mode and use the ⇑ / ⇓ I N 2 C A L I B R A T . keys to select the option “IN2 CALIBRATION”... -
Page 15: Errors/Alarms
ERRORS AND ALARMS Every error or anomaly detected by the system generates an alarm message on the display: LEV1 / LEV2 The level sensor 1 or 2 detected a low level of the liquid to be dosed; restore the level into the related tank FLOW The flow sensor detected an anomaly that can be due to low pressure into the hydraulic circuit... -

pH and Redox Electrodes Typically, it is recommended to clean the electrodes when the response is slow or measurements are not reliable, and when they have been used for a long time, especially in aggressive solutions, pollutants, very acidic or very alkaline environments.
