personnel
All installations must be carried out by authorised and competent personnel
only. Authorised persons must
- install the system in dry and well-ventilated place;
- ensure the correct installation of equipment required for the correct function-
ing of the pump;
- only use accessories that have been supplied with the system.
ATTENTION The use of accessories that are unsuitable and were not provided with the
system is strictly prohibited. Piusi S.p.A. accepts no responsibility for damage
to persons, property or the environment caused by failure to comply with this
requirement.
THE DISPENSING SYSTEM IS FOR PROFESSIONAL USE ONLY.
As per the current legislation, the dispensing system must be used n premises
that are sufficiently well-lit.
The dispensing system has been specifically designed for use in a dry place. If
installed outside, an adequate protective covering must be provided.
Motors are not explosion-proof. DO NOT install SELF SERVICE in places with
danger of explosion.
12.1 POSITIONING
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 instal-
lation:
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

12.3 HYDRAULIC CONNECTIONS
ATTENTION The use of accessories that are unsuitable and were not provided with the
system is strictly prohibited. Piusi S.p.A. accepts no responsibility for damage
to persons, property or the environment caused by failure to comply with this
requirement.
Always follow the below-listed instructions:
- Use pipes and joints suitable for operation in vacuum conditions.
- Use pipes and accessories suitable for treated fluid. Unsuitable materials can
result in serious damage to the pump; they can also cause pollution.
- Do not use conical threaded connectors that could cause damage to the
threaded connector on the pump filter if tightened excessively
- Use wide-radius bends so that pressure losses are reduced to minimum levels.
- Check that suction pipe is perfectly clean and free from scales.
- Install a FOOT VALVE equipped with FILTER at suction pipe end. Place the
foot valve on tank bottom. Foot valve and pipe must have the SAME DIAM-
ETER.
- Before starting installation, make sure that no packing material has been left
in the 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 DIAM-
ETERS of the suction pipe must always be ensured.
MAXIMUM
LENGTH OF
THE SUCTION
PIPES
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 back pressure greater than 0.6 bar. It fol-
lows as a consequence that, after respecting the minimum diameter of the tub-
ing 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.
RECOMMEN-
DATIONS 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 back-pressure.
- 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.

ATTENTION For CUBE MC commissioning, no further power connections are required. All the elec-
tronic 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).
The installer should carry out a plug/socket connection for a quick sectioning
of the electric system in case of failures.
Below are the main connections and the fuses to be replaced by skilled service
technicians only.

13 STARTING
FOREWORD 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).
ELECTRICAL
POWER
SUPPLY
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.
WETTING
THE PUMP
CUBE MC features a self-priming pump that makes first startup easier. To start the appli-
ance, the suction pipe need not therefore be completely full of diesel fuel. For quick prim-
ing, 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.
STATION
CONFIGURATION
Every CUBE MC station can be adapted to the specific requirements of the sta-
tion manager.T o do this the MC control system must be CONFIGURED.
ATTENTION
MC configuration is crucial and must be done by skilled personnel. To perform
this operation, the MC manual must be carefully and thoroughly read.
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
DISENGAGING
THE
“MC” SYSTEM
All the CUBE MC functions are controlled by the MC control system. The MC
system can never the less be disengaged for any startup or maintenance ac-
tivities 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).
ATTENTION
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
In MANUAL mode:
• The MC LCDs could be off or continue
to display whatever was showing at the
time of switch over from AUTO to MAN.
• To start the pump, no PIN CODE is re-
quired; 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.

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.
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:
• 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 chapter “HYDRAULIC CONNECTIONS”.
• 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.
