To ensure operator safety and to protect the pump from potential
damage, workers must be fully acquainted with this instruction manual
before performing any operation.
CUBE dispensers are appliances designed for the private distribution of diesel fuel for
motor transport. Featuring absolute safety and ease of use, CUBE dispensers are extremely
reliable high-performance ready-to-use units that are fast to install. All models in the series
share the solid metal frame and self-priming pumps, while they differ in terms of the types of
flow meter (mechanical or electronic) and the presence on certain models of an electronic
delivery management system.
CUBE's strengths lie in the reliability of the pumping units, the metering precision of product
dispensed, and the high performance of the management systems.
THE PERSONNEL WHO USE THE DISPENSER AND THE TECHNICAL SUPPORT
PERSONNEL MUST BE FAMILIAR WITH THE FIRST AID AND SAFETY RULES
DESCRIBED IN THIS MANUAL.
Keep this technical manual in a place that is familiar and accessible to all the personnel
who have access to the dispenser.

Operation in bypass mode is permied only for short periods (/ minutes max.).
The flow rate value is referred to the following operating conditions:
fluid: diesel fuel
temperature: °C
Suction conditions: the suction line and pump position with respect to the fluid level is such as to create a
. bar vacuum at nominal flow rate.
With different suction conditions higher vacuum values may be created thus reducing the flow rate
considering the same back-pressure values.
To obtain the highest performance it is essential to limit pressure drops on the suction line as far as
possible by observing the following recommendations:
¦ shorten the suction line as much as possible;
¦ avoid elbows and restrictions;
¦ keep the suction strainer clean;
¦ use hose of recommended diameter or larger (see installation).

Before installation, verify that no packing material has been trapped in the tubing.
Prepare suitable stilts or fixing brackets depending on the fixing position of CUBE. The hose
coming from the tank must be aligned to the threaded inlet of the pump filter which is located
under CUBE.
Maximum length
of suction hose
The maximum length of the tubing, the diameter of the tubing, the
difference in height, are parameters that are tightly linked to creating
suction conditions. The laer must not be such as to create backpressure
greater than . bar. It follows as a consequence that, aer respecting
the minimum diameter of the tubing specified in the "Aention" box
below, the length of the tubing decreases as the difference in height that
the diesel fuel must overcome increases and vice versa: in fact, the back
pressure progressively increases by . bar for every meter increase in
the static height of the pump with respect to the level of the diesel fuel in
the tank.
¦ Suction tubing must resist a pressure of at least 10 bar and must be of a diameter NOT LOWER than '';
¦ tubing must be suitable to functioning under backpressure;
¦ use tubing and accessories suitable for use with diesel fuel. Materials that are not suitable
for use with diesel fuel can cause damage to the pump, harm people and cause pollution;
¦ any curves in the suction hoses must be of the widest radius possible to limit the loss of head;
¦ make sure that the suction tubing is clean and free of scum.

Filling the pump The pump provided with CUBE is a self-priming pump capable of
suctioning an empty hose, nevertheless, the pump should be partially
filled with diesel fuel before turning it on for the first time.
It is le to the technician's experience to determine the best way to fill
the pump.
