priming tubes, the priming of the pump can
require from several seconds to several
minutes, as a function of the characteristics
of the system.
The pump provided with the CUBE is a
self-priming pump capable of suctioning an
empty tube, nevertheless, the pump should
be partially filled with diesel fuel before
turning it on for the first time.
It is left to the technician's experience to
determine the best way to fill the pump.
Simply introduce the cable with the Schuko plug into the
hole at the bottom of the CUBE (see picture aside) and
connect the plug to a grounded outlet of the household
type.
Connect the ground wire to a grounding connection
prepared according to the regulations.
The electrical connections must be performed

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 3 meters;
- the residual air in the tubes has been evacuated.
! Recommendations and warnings
• To correctly check accuracy, always keep to the following instructions:
• Use a precision sample container, featuring a graduated measuring scale, with a capacity
of at least 20 litres.
• Before making the check, always make sure you have eliminated all the air from the system
and then run the fuel until a full and regular flow is achieved.
• Dispense in a continuous way at maximum CUBE flow rate.
• Stop the flow by quickly closing the nozzle.
• Reach the graduated area of the container, avoiding prolonged dispensing at low flow
rates; prefer short dispensing operations at maximum flow rate.
• Compare the reading provided by the container, with that provided by CUBE, after waiting
for all the froth to disappear.
! Recommendations and warnings
Differences up to 0.2 litres out of every 20 litres fall within the guaranteed accuracy of +/- 1%.

The pump filter must be cleaned weekly or more often whenever a
reduction in flow rate is noticed.
The frequency required depends most of all on the quantity of fuel
dispensed, but also on other causes as well, such as dispensing fuel
immediately after refilling the tank, which stirs up sediment which
normally lies at the bottom.
To gain access to the filter:
• Remove the upper part of the Cube (and the side part for the
version CUBE 70), by unscrewing the 6 side screws (see Opening
and Closing the Cube)
• Screw off the 2 screws on the filter cover.
• To clean it, it is sufficient to wash it and blow through it.
- Check weekly and keep the pump body, tubing
and flanges clean to promptly reveal any leaks.
- Keep the dispensing nozzle tube clean and
especially the hole for the excess pressure
probe at the end of the nozzle tube (Fig. 4.2).
- With equal frequency or at least every time the
tank is filled, clean the filter and check valve at
the bottom of the tank.
- Every three months (or more often in case of
doubt) verify the accuracy of the meter.
- Screw off and remove the three cross-head screws
on the left side of the CUBE (Fig. 4.1, screws A).
- Screw off and remove the three cross-head screws
on the right side of the CUBE (Fig. 4.1, screws B).
- Raise the CUBE higher part.
- To reclose it, perform these steps in reverse
order.
