Multifunction pump
The metering pump can operate in either Proportional or manual mode. At the first power on you can choose the
operating configuration of the equipment.
With reference to the following table, the operator can select the mode that best suits his metering needs: only some of
the many programming menus will be made available, so you get a simplification and speeding up of the device
commissioning.

Once the configuration is set, scrolling the menu with the RIGHT () and LEFT () arrow keys, confirm the choice with
the START / STOP button. For an eventual reconfiguration it is necessary to do a TOTAL RESET.
Injection Calibration Procedure
For accurate metering, in the eOne and MF Plus models we have implemented the option to automatically or manually
set the actual flow rate for each injection. The following describes the practices that must be observed for "AUTOMATIC"
calibration:


Fill a graduated cylinder with the additive to be dosed by the pump and immerse the suction tube in it.

Connect the delivery pipe of the metering pump to the plant to be treated.

From the "SETTINGS" menu select the function "FLOW CAPACITY" and select the "AUTOMATIC" mode.

Press the DOWN ARROW button to proceed to the priming of the metering pump which will begin to emit
injections, until the pump body and the two suction and discharge pipes are full.

Once finished priming press the DOWN ARROW button.

Select the frequency of calibration procedure by press RIGHT AND LEFT ARROW buttons (standard value is
150 imp/min.).

Press DOWN ARROW button. The pump will run for one minute.

Once the injections are finished the metering pump will have suctioned a certain amount of additive whose
quantity can be calculated by means of the scale on the cylinder.

The amount of suctioned fluid, for example: 110 ml, should be set on the display and via the ARROW DOWN
button the selected value will be confirmed.

The logic of the pump will run the following operation:
value of additive suctioned / number of impulses delivered = flow rate of each injection
(110 / 150 = 0.73)

the factory-set value of 0.45 ml will become 0.73 ml.
