4.6- Start-up
Unscrew the filler screw (2) on the pump housing.
Using a receptacle, fill the suction hose and pump casing until overflowing occurs (do not throw water /
gasoil on the electrical parts).
Put the screw (2) back in place and screw it sufficiently tight to prevent air intake.
If the water/gasoil level drops in the pump body, or if discharge does not occur, re-check the suction hose
assembly and proceed to again priming the pump body.
Ensure that there is no water/gasoil on the electrical parts of the pump and that there is no leakage.
Operate the pump to check there is no leakage.
In the priming phase, the pump must blow the air initially present in the entire installation out of the
delivery line. Therefore it is necessary to keep the outlet open to permit the evacuation of the air.
ATTENTION: If an automatic type dispensing nozzle is installed at the end of the delivery line, the
evacuation of the air will be difficult because d the automatic stopping device that keeps the valve closed
when the line pressure is too low. It is recommended that the automatic dispensing nozzle be temporarily
disconnected during the initial start-up phase.
The priming phase can last from several seconds to a few minutes, as a function of the characteristics of
the system. If this phase is prolonged, stop the pump and verify:
- That the pump is not running completely dry;
- That the suction tubing is not allowing air to seep in;
- That the suction filter is not clogged;
- 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 far
the pump.
4.7- Before use
- Check that the residual quantity of water/gasoil in the suction tank is greater than the amount you wish
to transfer.
- Do not run the pump dry. This can cause serious damage to its components.
- Make sure that the tubing and line accessories are in good condition.
- Diesel fuel leaks can damage objects and injure persons.
- Never start or stop the pump by connecting or cutting out the power supply.
- Do not operate switches with wet hands.
- Prolonged contact with diesel fuel can damage the shin.
- The use of safety goggles and gloves is recommended.
ATTENTION: Extreme operating conditions with working cycles longer than 2 hours can cause the
motor temperature to rise, thus damaging the motor itself.
Each 2 hours working cycle should always be followed by a 30 minute power-off cooling phase.
