INSTALLATIONH
H1 GENERAL
H2 STATION POSITIONING
H3 MECHANICAL INSTALLATION
CUBE MC can be installed outside. Nevertheless, it is advisable to locate it under the shelter
of a roof to ensure the dispenser's longevity and provide greater comfort during refuelling in
the event of bad weather. The installation of the dispenser must be carried out by skilled
personnel and performed according to the instructions provided in this chapter.
Whenever CUBE MC is not installed under cover, a "display cover" is provided to protected the
display and keyboard.
The CUBE MC stations can be connected both to tanks above ground and tanks under ground.
The positioning of the SELF SERVICE must be such that it is possible to:
- Easily remove the panels to access the inner components when necessary.
- Observe the distances and maximum differences in level between the station and the tank.
- Securely fasten the casing to the ground on a horizontal surface.
Station positioning determines the following parameters, which distinguish each installation:
Hp: Priming height
Ls: Total length of the suction pipe - from the foot valve to the station
(expressed in metres)
To ensure correct station operation, the following limitations must always be kept to:
Hp max: not over 3 metres
LS max: not over 15 metres
Before starting installation, make sure no packaging materials are trapped in the pipes.
Prepare suitable stilts or fixing brackets depending on the fixing position of the CUBE MC.
The tube coming from the tank must be aligned to the threaded inlet of the pump filter which
is located under the CUBE MC.

H4 HYDRAULIC CONNECTIONS
H5 ELECTRICAL CONNECTIONS
H4.1 MAXIMUM LENGTH OF THE SUCTION PIPES
SUCTION LINE
The diameter of the "Ds" suction line must be selected according to the station model and the
position of the station with respect to the tank.
With reference to the "Hp" and "Ls" values indicated at point H2, the following MINIMUM
DIAMETERS of the suction pipe must always be ensured.
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 latter must not be such
as to create backpressure greater than 0.6 bar. It follows as a consequence that, after
respecting the minimum diameter of the tubing specified in the "Recommendations and
Warnings" 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 0.08 bar for every meter increase in the static height of the pump with respect to
the level of the diesel fuel in the tank.
The power connections must be workmanlike performed by skilled personnel, in strict
compliance with the laws applicable in the country of installation and with the instructions on
the wiring diagrams in this manual.
Maximum acceptable electrical parameter variations are ±5%.
RECOMMENDATIONS AND WARNINGS:
- The suction pipe must resist a pressure of at least 10 bar and must be of a diameter
NOT LOWER THAN 1'' 1/4.
- The 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 pipes must be of the widest radius possible to limit the loss of head.
- Make sure that the suction pipe is clean and free of scum.
EN
12
(Translated from Italian)
In all cases, always take the following PRECAUTIONS:
- Use pipes and connections suitable for vacuum operation.
- Use pipes and accessories suitable for use with diesel fuel. Materials that are not suitable
for such use can cause serious damage to the pump or injury to people; they can also be
the cause of pollution.
- Do not use conical threaded connectors that could cause damage to the threaded
connector on the pump filter.
- Use large-radius bends so as to reduce flow resistance to a minimum.
- Make sure that the suction pipe is clean and free of scum.
- At the end of the suction pipe, always fit a FOOT VALVE complete with FILTER. The valve
must be placed on the bottom of the tank and be of the SAME DIAMETER as the pipe.
- Before starting installation, make sure no packaging materials are trapped in the pipes.
! ATTENTION
The CUBE MC dispenser does not feature overload cutouts and, consequently, a
switchboard must be fitted upstream of the CUBE MC complete with residual current
circuit breaker suitable for the type of CUBE MC to be installed.
! ATTENTION

CUBE MC features a terminal board cover. Inside this cover are the terminals which the
installer must connect up to:
- The mains power line
- The RS 485 data line to the PC (optional).
The connector block, accessible through the front panel opening, is already wired up to the
CUBE MC components, according to the block diagram shown below.
1- Remove the right terminal
board cover.
2- Connect the cables as
shown in the diagram.
3- Close the terminal board
cover box again.
NOTE: The parts indicated in the diagram are the only connections to be made by the customer:
- Connection to power mains.
- RS485 output to PC (OPTIONAL).
EN

(Translated from Italian)
The installer should carry out a plug/socket connection for a quick sectioning of the
electric system in case of failures.
! ATTENTION
For CUBE MC commissioning, no further power connections are required.
All the electronic components housed in the MC BOX are already wired up and factory
tested.
It is therefore NEVER necessary for the installer or station manager to open the MC BOX
except to replace the protection fuses housed on the I/O card (see photo below).

COMMISSIONINGI
I1 ELECTRICAL POWER SUPPLY
I2 WETTING THE PUMP
I3 STATION CONFIGURATION
I4 DISENGAGING THE "MC" SYSTEM
To correctly commission the CUBE MC the sequence of operations indicated below must be
followed and the MC control system functions must be known (see attached manual).
Once the power connections have been made, the CUBE MC can be energised by means of
the master switch to be fitted by the installer on the upstream line. Switching on of the MC
system will be indicated by the lighting up of the two backlit LCDs fitted on the front.
Even when the nozzle is taken out of its seat, the pump WILL NOT start as it has not been
enabled by the MC system.
CUBE MC features a self-priming pump that makes first startup easier. To start the appliance, the
suction pipe need not therefore be completely full of diesel fuel. For quick priming, especially in
the case of installations distinguished by a considerable difference in level between the pump
and the tank, it is however important for the pump to be "wetted", meaning that there must be a
small quantity of diesel fuel inside the impeller chamber.
The pump is supplied adequately "wetted" and ready for use. If however the installer considers
the pump to be totally dry, perhaps due to prolonged storage, he will have to wet it as he thinks
best.
Every CUBE MC station can be adapted to the specific requirements of the station manager.
To do this the MC control system must be CONFIGURED.
After completing configuration, user PIN CODES can be assigned to the persons charged with
using CUBE MC, in accordance with the detailed information in the MC manual.
All the CUBE MC functions are controlled by the MC control system. The MC system can
nevertheless be disengaged for any startup or maintenance activities requiring repeated
pump starting.
In these case, it is often convenient to simplify pump startup by not having to enter any code
and record any dispensing data.
To do this, a JUMPER has been fitted on the card that permits switching from AUTOMATIC
mode (code request to access dispensing) to MANUAL mode (no code request).
EN
15
(Translated from Italian)
MC configuration is crucial and must be done by skilled personnel.
To perform this operation, the MC manual must be carefully and thoroughly read.
! ATTENTION

ON Position OFF Position
In MANUAL mode:
• The MC LCDs could be off or continue to display
whatever was showing at the time of switchover
from AUTO to MAN.
• To start the pump, no PIN CODE is required; the
pump will start as soon as the nozzle is taken off
its seat and will stop when the nozzle is put
back.
• The quantity dispensed by CUBE MC is not
indicated in any way.
To prime the pump:
- Take the nozzle off its seat
- Enter the previously assigned PIN CODE (if the jumper is on)
- Lift the control lever
- The pump will start immediately and will continue running indefinitely until the control lever
is moved to OFF position.
Operate the lever of the automatic nozzle, keeping the spout inside an adequate container or
the same suction tank.
Air will first of all come out of the nozzle and then DIESEL FUEL will gradually begin to flow.
I5 FIRST PRIMING
EN
16
(Translated from Italian)
The jumper is only accessible by opening the front panel and is positioned as shown in the
photo. In this operating mode, MC does not record any data relating to performed
dispensing operations.
BEFORE ACCESSING THIS JUMPER, ALWAYS INTERRUPT THE POWER SUPPLY
! ATTENTION
The first priming of the pump must be done by skilled personnel who must monitor all
the various stages involved.
If only air continues to come out after more than two minutes, STOP THE PUMP and
make sure:
! ATTENTION

• This is not working dry, but is at least "wetted" with diesel fuel.
• The suction pipe prevents any air from infiltrating and that this is completely submerged.
• The filters are not blocked.
• The suction and/or supply lines are not blocked.
• Installation (level difference, diameter and pipe length) is within the limits indicated at point H4.
• The disconnection valve is closed.
Continue dispensing until the flow is regular and air free.
Position the control lever in OFF position:
- The pump stops.
Place the nozzle back in its seat.
Before using the CUBE MC station, check the METER ACCURACY.
For this purpose, proceed as follows:
• Enter a previously enabled USER PIN code.
• Run the fuel into a calibrated container.
• Compare the quantity of dispensed diesel fuel using a calibrated container.
If accuracy is NOT satisfactory, proceed to CALIBRATE THE METER according to the
instructions in the specific manual.
I6 METER CALIBRATION
EN
17
(Translated from Italian)
Differences of up to 1/10 of a litre affecting the dispensing of 20 litres of fluid fall within
the guaranteed accuracy of +/- 0.5%.
! ATTENTION
To correctly check accuracy, always keep to the following instructions:
• Use a precision sample container, featuring a graduated 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 continuously at CUBE MC maximum flow rate
• Stop the flow by quickly closing the nozzle.
• Reach the graduated area of the sample container, avoiding prolonged dispensing at
low flow rate, but rather performing short dispensing operations at maximum flow rate.
• Compare the reading provided by the container, with that provided by CUBE MC,
after waiting for all the froth to disappear.
! ATTENTION

DAILY USEL
L1 FUEL DISPENSING
Thanks to the MC control system, all the CUBE MC models provide access to authorised
users only.
MC acknowledges User authorisation by means of two alternative systems:
- The entering of a 4-figure SECRET CODE (PIN CODE).
- The fitting of an electronic key (OPTIONAL).
The configuration of the MC system permits requiring the User to enter further optional data
(vehicle licence plate, mileage, quantity to be dispensed).
See MC manual (M0103) for details.
If these options are not set, MC recognises an authorised PIN CODE and immediately enables
the pump to dispense fuel.
The pump will start (if previously enabled) just as soon as the control lever is moved to ON
position, while it switches off as soon as the control lever is moved to OFF position.
No further manual operation is required to start or stop the pump.
In the case of the simplest configuration (no optional data required), the fuel dispensing
procedure is the following:
1 Enter PIN CODE
If the MC recognises an authorised code, it displays the following messages and enables the pump.
EN
18
(Translated from Italian)
Fuel MUST ONLY be dispensed under the careful control of the User.
! ATTENTION
Such enabling does not result in immediate pump startup. The pump is in fact
controlled by a switch (positioned in the nozzle seat) operated by the user.
! ATTENTION
All the users to whom a PIN CODE is assigned must be adequately instructed and be
at least acquainted with the contents of this chapter.
! ATTENTION

2 Move the control lever to ON position (see photo on page 16)
MC operates the pump.
3 Operate the nozzle lever to start the dispensing operation
MC indicates the dispensed quantity.
4 After terminating the dispensing operation, rewind the hose around the hose carrier,
move the control lever to OFF position and put the nozzle back in its seat.
MC stops the pump.
ROUTINE MAINTENANCEM
CUBE MC has been designed so as to require minimum maintenance. For utmost station
efficiency and safety, the following inspection and ROUTINE maintenance operations should
however be regularly performed.
Check the pump, the pipes and other internal components of the station and keep them clean.
Make sure there are no leaks in the flanged or threaded connections and that the hoses are

If there is a power cut or the pump stops, the operator has to put the nozzle back in the
unit seat. Remember that the nozzle can be opened only when the spout is in the tank.
! ATTENTION
The dispensing operation can be interrupted as required. If the interruption continues
for over a certain time (which can be set as required by the station manager during MC
configuration) the pump is stopped and disabled. To continue dispensing fuel, the
various steps will have to be repeated starting from no. 1.
! ATTENTION
Never operate the nozzle lever before placing this in the fuel container

Keep the dispenser pipe and nozzle clean and make sure especially that:
- The pipe is in perfect condition and has not been damaged by vehicle transit.
- The threaded connections are tight and not leaking.
- The swivel connections (at dispenser exit and on the nozzle) are turning freely and do not
show leaks.
- Keep the dispensing tube and nozzle clean and check that the automatic stop feeler hole
at the end of the spout is always clean.
The MC system is maintenance free. To control it however, refer to the dedicated M0103
manual provided.
CUBE MC features a number of filters having different functions. The inspection and cleaning
(or replacement) of each filter is crucial to ensure:
- The protection of the various station components (pulser, pump, nozzle).
- Station performance remains high over the years (maximum flow rate).
- Protection of the engines using the dispensed diesel fuel.

(Translated from Italian)
Dirty or partially blocked filters can increase flow resistance and cause a considerable
reduction in the maximum flow rate of the pump.
Dirty or blocked pump suction filters also cause a big increase in vacuum during
suction and this in turn can make the pump particularly noisy.
