PRIMING FUNCTION
In order to facilitate the priming the pump is equipped with PRIMING function. It's recommended to open the bleed
air by-pass on pump head (for pumps with it) during priming. The air bleed nipple must always be connected with the
return hose to the suction tank.
The activation of this function can occur at any operating menu in the following way:
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:

Press and hold START/STOP button
•
After about 3 seconds the pump starts delivering injections at the priming frequency of 150 imp/min, as
•
long as the operator does not release the START / STOP button. When you press the button the following
screen appears on the display:
Once you release the button, the pump stops 10 sec. countdown starts. At the end the pump switches
•
back to the previous operating mode, in stand-by condition. Pressing the START / STOP button the pump
goes in running mode.
During the countdown pressing and holding down START/STOP the pump starts to give injections to
•
reach the right dosing condiction to existing system pressure. We recommend that you use this procedure
to return the pump in optimal working condition especially if it operates at any proportional mode. During
this phase, you should close of the bleed valve on the pump body. Once you release the button, the pump
will return to stand-by mode.
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.
