IF THE PUMP
DOES NOT PRIME
AT THE END OF
THE INITIAL
START-UP
L EVERY DAY USE
USE PROCEDURE 1 If flexible pipes are used, attach the ends of the piping to the
tanks. In the absence of an appropriate slot, solidly grasp the
delivery pipe before beginning dispensing.
2 Before starting the pump make sure that the delivery valve is
closed (dispensing nozzle or line valve)
3 Turn the ON/OFF switch on
4 Open the delivery valve, solidly grasping the pipe
5 While dispensing, do not inhale the pumped product
6 Should you spill any fluid while dispensing, bank it with earth or
sand to absorb it and limit its spreading
7 Close the delivery valve to stop dispensing
8 When dispensing is finished, turn off the pump
NOTICE
M0307
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 mt. (6.5 ft)
- that all air has been released from the delivery pipe.
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 0.5 bar (7 psi)
- that the delivery back pressure does not exceed the
maximum back pressure for the pump.
The by-pass valve allows functioning with delivery
closed only for short periods (max. 3 minutes)
To avoid damaging the pump, after use, make sure
the pump is off.
In case of a power break, switch the pump off straight
away.
Should any sealants be used on the suction and
delivery circuit of the pump, make sure that these
products are not released inside the pump.
Foreign bodies in the suction and delivery circuit of
the pump could cause malfunctioning and breakage
of the pump components.
In case of prolonged dry-running of the pump, the
suction circuit may be empty and suction may be-
come difficult. If so, fill the suction circuit with dem-
ineralised water
