•
During the countdown pressing and holding down START/STOP the pump starts to give injections to
reach the right dosing condition 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.
•
The PRIMING function can be utilized when the pump PASSCODE is activated. To do this press and
hold the START/STOP button, after 3 seconds the pump starts injecting at the priming frequency (150
strokes/min) until you release the START/STOP button. At the end of the sequence the pump will go back to
the previous mode. You will need to enter the password that you have previously used to get access the
different menus.
Special Warnings for the Metering of Sulphuric Acid (max. 50%)
In this case it is essential to bear in mind the following:
•
replace the transparent PVC suction hose with a semi-rigid polyethylene delivery tube.
•
remove in advance all the water present in the pump body, in fact if this is mixed with the sulphuric acid it
generates a strong concentration of gas resulting in the overheating of the area causing damage to the
valves and the pump body.
If the equipment is not attached to the system you can carry out this operation, by activating the pump for a
few seconds (15 -30) holding it upside down with no tubes connected to the fittings, if that is not possible
then disassemble and reassemble the pump body (Fig .10), via the four fixing screws.
