SPECIAL WARNINGS FOR THE METERING OF SULPHURIC ACID (MAX. 50%)
In this case it is essential to bear in mind the following:
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.
OPERATIONAL INSTRUCTIONS (COMMISSIONING)
Control Panel
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.
