Differences up to
litres out of every litres
fall within the guaranteed
accuracy of +/- %.
NOTE
Priming
the pump
It is advisable to oversee the first priming phase to make sure that
this is happening in a reasonable amount of time: depending on the
length and fill status of the priming hoses, the priming of the pump
can require from several seconds to several minutes, as a function
of the characteristics of the system.
Calibrating the
meter
Before using the CUBE station,
check METER ACCURACY.
For this purpose, proceed as
follows:
¦ take out the nozzle and start the
pump as described in the above
paragraph;
¦ run the fuel into a calibrated
container.
If this phase is excessively prolonged, stop the pump and verify that:
¦ the pump is not running completely dry;
¦ the suction tubing is air-tight and completely immersed in the fluid to be pumped;
¦ the suction filter is not clogged;
¦ the difference in height for priming is not greater than meters;
¦ the residual air in the hoses has been evacuated.
CUBE is compatible with automatic type nozzles. Air bleeding may prove difficult due to
the automatic stop device, which keeps the valve closed when the line pressure is too low.
Temporarily detach the automatic nozzle during the commissioning procedure.
ATTENTION
If accuracy is NOT satisfactory, proceed to CALIBRATE THE METER:
¦ Bleed all air from the system (pump, hoses, flow meter) by delivering
fluid until obtaining a full and even flow.
¦ Stop delivery by closing the dispenser nozzle without stopping the
pump.
¦ Reset the partial counter by means of the reset knob (see: "how to
dispense fuel" in paragraph ).
