ATTENTION!
IT IS THE INSTALLER’S RESPONSIBILITY TO PREFORM THE ELECTRICAL CONNECTIONS WITH
RESPECT FOR THE APPLICABLE REGULATIONS.
Respect the following (not exhaustive) instructions to ensure a proper electrical installation:
• During installation and maintenance, make sure that the electric supply lines are not live.
• Use cables characterized by the minimum cross-sections, nominal voltages and wiring-type adequate to
the electrical characteristics shown in paragraph E2 – ELECTRICAL SPECIFICATIONS and the installation
environment.
• Always close the cover of the strip box before supplying electrical power.
• Check the correct rotation direction of the pump.
If it is inverted, check the polarity of the connection cable.
G. INITIAL START-UP
• Check that the quantity of diesel fuel 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.
• Do not run the pump dry. This can cause serious damage to its components.
• Make sure that the tubing and line accessories and in good condition.
• Diesel fuel leak can damage objects and injure person.
• 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 skin. The use of glasses and gloves is recommended.
ATTENTION!
Extreme operating conditions with working cycles longer than 30 minutes can cause the motor
temperature to rise, thus damage the motor itself.
Each 30-minute working cycle should always be followed by a 30-minute power-off cooling phase.
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 of 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 second 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;
