INITIAL START-UP
FOREWORD
Check that the quantity of fluid in the suction tank is greater than the amount you wish to transfer.
Make sure that the residual capacity of the delivery tank is greater than the quantity you wish to transfer.
Make sure that the piping and line accessories are in good condition.
ATTENTION
Do not run the pump dry for more than 20 minutes. This can cause serious damage to
its components. Fluid leaks can damage objects and injure persons.
NOTE
Never start or stop the pump by connecting or cutting out the power supply. Prolonged contact
with some fluids can damage the skin. The use of goggles and gloves is recommended.
ATTENTION
Extreme operating conditions with duty cycles longer than 20 minutes can cause the
motor temperature to rise thus damaging the engine. For each duty cycle of 20 minutes, allow for a rest phase
of 20 minutes with motor switched off.
NOTE
During the priming phase, the pump must discharge all the air that is initially present from the
delivery line. Therefore it is necessary to keep the outlet open to permit the evacuation of the air.
WARNING
If an automatic type dispensing nozzle is installed on the end of the delivery line, the
evacuation of the air will be difficult because of the automatic stopping device that keeps the valve closed. It is
recommended that the automatic nozzle be temporarily removed during initial start-up.
IF THE PUMP DOES NOT PRIME
Depending on the system characteristics, the priming phase can last from several seconds to a few minutes. If
this phase is prolonged, stop the pump and verify:
-That the pump is not running completely dry (fill with fluid from the delivery line)
-That the suction pipe guarantees against air infiltration
-That the suction filter is not clogged
-That the suction height is not higher than 2 m
-That all air has been released from the delivery pipe
AT THE END OF THE INITIAL START-UP
When the 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 0.5 bar
-That the delivery back pressure does not exceed the maximum back pressure for the pump.
EVERY DAY USE
USE PROCEDURE
1.
If flexible pipes are used, attach the end of the piping to the tanks. In the absence of an appropriate
slot, solidly grasp the delivery pipe before beginning dispensing.
