4 SAFETY INSTRUCTIONS
Mains - pre-
liminary checks
before instal-
lation
ATTENTION
You must avoid any contact between the electrical power supply and the
fluid that needs to be FILTERED.
Maintenance
control Before any checks or maintenance work are carried out, disconnect the
power source.
FIRE AND
EXPLOSION
When flamma-
ble fluids are
present in the
work area, such
as gasoline
and windshield
wiper fluid,
be aware that
flammable
fumes can ig-
nite or explode.
To help prevent fire and explosion:
Use equipment only in will ventilated area.
Keep work area free of debris, including rags and spilled or open containers
of solvent and gasoline.
Do not plug or unplug power cords or turn lights on or off when flammable
fumes are present.
Ground all equipment in the work area.
Stop operation immediately if static sparking occurs or if you feel a shock.
Do not use equipment until you identify and correct the problem.
Keep a working fire extinguisher in the work area.
ELECTRIC
SHOCK
Electrocution
or death
FThis equipment must be grounded. Improper grounding, setup or usage of
the system can cause electric shock.
Turn off and disconnect power cord before servicing equipment.
Connect only to a grounded electrical outlets.
Use only 3 wire extension cords in accordance with local electrical codes.
Extension cords should have a ground lead.
Ensure ground prongs are intact on power and extension cords.
Do not expose to rain. Store indoors.
Never touch the electric plug of socket with wet hands.
Do not turn the dispensing system on if the power connection cord or other
important parts of the apparatus are damaged, such as the inlet outlet
plumbing, dispensing nozzle or safety devices. Replace damaged compo-
nents before operation.
Before each use check that the power connection cord and power plug are
not damaged. If damaged, have power connection cord replaced before use
by a qualified electrician.
The electrical connection between the plug and socket must be kept well away
from water.
Unsuitable extension leads can be hazardous, in accordance with current
regulations. only extension cords that are labelled for outdoor use and have
a sufficient conduction path should be used outdoors.
For safety reasons, we recommend that, in principle, the equipment be used
only with a earth-leakage circuit breaker (max 30 mA).
Electrical connections must use ground fault circuit interrupter (GFCI).
Installation operations are carried out with the box open and accessible
electrical contacts. All these operations have to be done with the unit
isolated from the power supply to prevent electrical shock!

11 INTENDED USE
WARNING
Flammable
liquids and explo-
sive atmosphere
The system was not designed for dispensing of diesel, petrol, flammable liquids
with flash point <55°C/131°F, or for operation in environments with potentially
explosive atmosphere. The use in the above mentioned conditions is forbidden.
ATTENTION
Environmental
conditions
The use of the system for purposes different from those specified in section
«Intended use» is strictly forbidden. Do not operate the system for any
purpose other than the purpose described within this manual; all other use
is considered «IMPROPER» and will result in Piusi S.p.A. disclaiming any re-
sponsibility for damage to property, people, animals or to the system itself.
Fluid Permitted DIESEL FUEL at a VISCOSITY from 2 to 5.35 cSt (at a temperature of 37.8°
/ 100°F C). Minimum Flash Point (PM): 55°C / 131°F
ATTENTION
Environmental
conditions
TEMPERATURE: min. –20° C / max +60° C
RELATIVE HUMIDITY: max. 90%
The temperature limits shown apply to the pump components and must be
respected to avoid possible damage or malfunction.
12 INSTALLATION
WARNING
Authorised
installation
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
functioning 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 dam-
age 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 prem-
ises 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
SELF SERVICE should be so positioned as to ensure
an easy removal of detachable panels when access to internal components is required;
compliance with max. distances and difference in height between station and tank;
correct and safe fixing of the body to the ground on a horizontal plane.
Unit position results in the following parameters, characterizing each installation
Hp: priming height
Ls: total length of suction piping – from foot valve to station (in meters)
Correct operation of the units requires full respect of the following limits:
Hp max: not exceeding 3 meters
LS max: not exceeding 15 meters
ATTENTION Place Self Service in a protected place.
In compliance with regulations in force, the dispensing system must be
used in premises that are sufficiently well-lit.

12.2 FIXING
The station should be attached to the ground with screw anchors suitable for M12 screws, to be placed as indi-
cated in the following pictures. The same figure also shows the two possible input positions (hose axis) of the
suction hose, for the two types of connection to UNDERGROUND tank or ABOVE GROUND tank.
Before fixing the unit, make sure that the bearing area for station frame is flat and strong.
To facilitate SUCTION line connection, SELF SERVICE units are equipped both with rear and bottom inlets

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 dam-
age 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
DIAMETER.
- Before starting installation, make sure that no packing material has been
left in the pipes.
SUCTION LINE The diameter of the suction line in the Self Service and Self Service Tank
stations should not be lower than 1” 1/2 Gas.
The connector is 1” 1/2 female Gas.
