• That the suction height does not exceed 2m. (if the height exceeds 2m, fill the suction hose with fluid);
• That the delivery tube is allowing the evacuation of the air.
When priming has occurred, verify that the pump is operating within the anticipated range, in particular:
• That under conditions of maximum back pressure, the power absorption of the motor stays within the
values shown on the identification plate;
• That the suction pressure is not greater than 0.5bar;
• That the back pressure in the delivery line is not greater than the maximum back pressure foreseen for the
pump.
H. DAILY USE
a. If using flexible tubing, attach the ends of the tubing to the tanks. In the absence of an appropriate slot,
solidly grasp the delivery tube before beginning dispensing.
b. Before starting the pump, make sure that the delivery valve is closed (dispensing nozzle or line valve).
c. Turn the ON/OFF switch on. The by-pass valve allows functioning with delivery closed only for brief
periods.
d. Open the delivery valve, solidly grasping the end of the tubing.
e. Close the delivery valve to stop dispensing.
f. When dispensing is finished, turn off the pump.
ATTENTION!
Functioning with the delivery closed is only allowed for brief periods (2 / 3 minutes maximum). After use,
make sure the pump is turned off.
