ATTENTION
The curve refers to the following operating conditions:
Fluid Diesel Fuel
Temperature 20 o C
Suction Conditions The tube and the pump position relative to the fluid level is such
that a pressure of 0.3 bar is generated at the nominal flow rate.
Under different suction conditions higher pressure values can be created that reduce the
flow rate compared to the same back pressure values.
To obtain the best performance, it is very important to reduce loss of suction pressure as
much as possible by following these instructions:
• Shorten the suction tube as much as possible
• Avoid useless elbows or throttling in the tubes
• Keep the suction filter clean
• Use a tube with a diameter equal to, or greater than, indicated (see Installation)

pump and its accessories. • Do not use conical threaded joints that
could damage the threaded pump
• Before connecting the delivery tube, openings if excessively tightened.
SUCTION TUBING:
- Minimum recommended nominal diameter: 1-1/4" (model E80)
1-1/2" (model E120)
- Nominal recommended pressure: 10 bar
- Use tubing suitable for functioning under suction pressure
DELIVERY TUBING
- Minimum recommended nominal diameter: 1"
- Nominal recommended pressure: 10 bar
ATTENTION
It is the installer's responsibility to use tubing with adequate characteristics.
The use of tubing unsuitable for use with Diesel fuel can damage the pump, injure
persons and cause pollution.
Loosening of the connections (threaded connections, flanging, gasket seals) can cause
serious ecological and safety problems.
Check all the connections after the initial installation and on a daily basis after that.
Tighten the connections, if necessary.

install an electric panel, upstream from the pump's power supply line, equipped with an
appropriate residual current operated circuit breaker.

ATTENTION
Extreme operating conditions can raise the motor temperature and, consequently,
cause the thermal protection switch to stop it.
Turn off the pump and wait for it to cool before resuming use.
The thermal protection automatically turns off when the motor is sufficiently cool.

out of the delivery line.
ATTENTION
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 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 • That the suction height is not greater than

Functioning with the delivery closed is only allowed for brief periods (2-3 minutes maximum).
After use, make sure the pump is turned off.
LACK OF ELECTRIC POWER:
A lack of electric power, with the consequent accidental stopping of the pump, can be cau-
sed by:
- A safety device tripping
- A drop in line voltage
In either case, act as follows:
a. Close the delivery valve
b. Attach the end of the delivery to the slot provided on the tank
c. Turn the ON/OFF switch to the OFF position.
Resume operations as described in Paragraph L - DAILY USE, after determining the cause of
the stoppage.
