- Make sure that the residual capacity of the delivery tank is greater than the
quantity you wish to transfer;
- Make sure that the level of liquid in the tank where the SQUALO pump is
located is sufficient to guarantee the suction;
- Make sure that the piping and line accessories are in good condition.
Do not run the pump dry. This can cause serious damage to its components.
Fluid leaks can damage objects and injure persons.
Do not start the pump unless it has been completely submerged in fluid.
- 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.
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 stop-
ping device that keeps the valve closed. It is recommended that the auto-
matic nozzle be temporarily removed during initial start-up.
Before start up, the suction part of the pump must be primed. Prime by means
of submerging the entire pump in the liquid, this ensures that the sealing sur-
faces are properly lubricated and that the pump can immediately dispense
the liquid.
- Turn the power supply switch upstream from the pump to position I (ON) and
wait until the liquid comes out of the delivery pipe.
- If malfunctions are found, disconnect the pump from the power supply, turn-
ing the power supply switch to position 0 (OFF) and consult the section on
"TROUBLESHOOTING".
When start-up has occurred, verify that the pump is operating within the an-
ticipated 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 delivery back pressure does not exceed the maximum back pres-
sure for the pump.
