WARNING
FIRE AND
EXPLOSION When ammable uids are present in the work area,
such as gasoline and wind-
shield wiper uid, be aware
that ammable fumes can
ignite or explode. To help
prevent re and explosion:
Use equipment only in will ventilated area.
Eliminate all ignition sources, such as cigarettes
and portable electric lamps.
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 o when ammable fumes are
present.
Ground all equipment in the work area.
Stop operation immediately if static spark-
ing occurs or if you feel a shock. Do not use
equipment until you identify and correct the
problem.
Keep a working re extinguisher in the work
area.
ELECTRIC
SHOCK
F
Electrocution or death This equipment must be grounded. Improper
grounding, setup or usage of the system can
cause electric shock.
Turn o and disconnect power cord before ser-
vicing 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 components
before operation.
Before each use check that the power connec-
tion cord and power plug are not damaged. If
damaged, have power connection cord replaced
before use by a qualied 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 ex-
tension cords that are labelled for outdoor use
and have a sucient conduction path should
be used outdoors.
For safety reasons, we recommend that, in prin-
ciple, the equipment be used only with a earth-
leakage circuit breaker (max 30 mA).
Electrical connections must use ground fault
circuit interrupter (GFCI).

Flow rate (l/min)
NOTE The curve refers to the following operating condi-
tions:
Fluid: DEF
Temperature: 20° C (68 °F)
Suction conditions: The pipe and the pump position
relative to the fluid level is such that a low pressure of
0.3 bar (4 psi) is generated at the nominal flow rate.
Under different suction conditions higher low
pressure values can be created that reduce the flow
rate compared to the same back pressure values. To
obtain the best performance, it is very important to
reduce loss of suction pressure as much as possible
by following these instructions:
• shorten the suction pipe as much as possible
• avoid useless elbows or throttling in the pipes
• keep the suction filter clean
• use a pipe with a diameter equal to, or greater than,
indicated (see Installation).
NOTE By-pass pressure is 1.7 bar (24 psi)
NOTE The wetted materials used in this device are :
stainless steel, plastic and rubber suitable for AdBlue.

I INSTALLATION
NOTICE The pump must never be operated before the delivery
and suction lines have been connected.
PRELIMINARY
INSPECTION - Verify that all components are present. Request any missing parts
from the manufacturer.
- Check that the pump has not suered any damage during trans-
port or storage.
- Carefully clean the suction and delivery inlets and outlets, remov-
ing any dust or other packaging material that may be present.
- Check that the electrical data corresponds to those indicated on
the data plate.
- Always install in an illuminated area.
- Install the pump at a height of min. 80 cm.
I.1 POSITIONING, CONFIGURATIONS AND ACCESSORIES
WARNING FIRE ANDEXPLOSION HAZARD
Themotors are not of theanti-explosive-type.
do not install them where inammable vapours could
be present.
WARNING EQUIPMENT MISUSE HAZARD
It is the responsibility of the installer to provide the
necessary line accessories to ensure the correct and
safe operationofthe pump. Theaccessoriesthat are
not suitable to be used with the previously indicated
material could damage the pump and/or cause
injury topersons,as well ascausingpollution.
NOTICE In the case of installation in the open air, proceed to
protect the pump by providing a protection roof.
The pump can be installed in any position (pump axis
vertical or horizontal)
The pump must be secured in a stable way using the
holes on the bed of the motor and vibration damping
devices.
NOTICE The broad range of pump accessories make it suit-
able for many different uses, installations and ap-
plications. The supporting base can be positioned in
different ways.
NOTE The pump can be installed in any position (pump axis
vertical or horizontal)
NOTICE To maximise performance and prevent damage
that could affect pump operation, always de-
mand original accessories.

EN I.2 NOTES ON SUCTION AND DELIVERY LINES
DELIVERY
EFFECTS ON
FLOW RATE Length and diameter of pipe, ow rate of dispensed liquid, accessories tted, can create back pressures above those allowed.
In this case, the pump mechanical control (bypass) will trip to reduce
the ow rate.
HOW TO REDUCE
EFFECTS ON
FLOW RATE
To avoid these problems, system ow resistances must be reduced
using shorterand/orlargerdiameterpipes, aswellaslineaccessories
with low resistances (e.g., automatic nozzle for higher ow rates).
NOTICE The delivery pipe must have the following technical
characteristics:
- recommended minimum nominal diameter: ¾”
- recommended nominal pressure: 10 bar (145 psi)
SUCTION
FOREWORD Diaphragm positive-displacement pumps are self-priming and
feature good suction capacity.
During the start-up phase, when the suction pipe is empty and the
pump is wet, the electric pump unit is able to suck liquid from a
maximum vertical distance of 2 mt.
NOTE Priming time can last a few minutes. We suggest
performing priming operations without automatic
nozzle and making sure the pump is properly wet.
NOTICE Always install a foot valve to prevent the suction pipe
from being emptied and to keep the pump wet at all
times. In this way, the pump will always start up im-
mediately the next times it is used.
CAVITATION The pump is able to work with vacuums of up to 0.5 bar (7 psi) at the
suction mouth. Over this value, CAVITATION can occur that causes a
fall in ow rate and increase in noise levels.
HOW TO PREVENT
CAVITATION It is important to ensure low vacuums at suction mouth by using: - short pipes with larger or identical diameter to that recommended
- reduce bends to the utmost
- use large-section suction lters
- use foot valves with minimum possible resistance
- keep the suction lters clean because, when they become clogged,
they increase the resistance of the system.
NOTICE The vertical distance between the pump and the fluid
must fall within the 2 mt.(6.5 ft) maximum required
for priming. If the distance is greater, a foot valve
must be installed to allow the suction pipes to fill up
and the diameter pipes must be larger. It is recom-
mended that the pump not be installed at a vertical
distance greater than 2 meters.
NOTICE If the suction tank is higher than the pump, an anti-
siphon valve should be installed to prevent acciden-
tal product leaks. Size the installation to contain the
back pressures caused by water hammering.
NOTICE It is a good system practice to immediately install
vacuum and air pressure gauges at the inlets and
outlets of the pump which allow verification that
operating conditions are within anticipated limits. To
prevent the suction pipes from being emptied when
the pump stops, a foot valve should be installed.
NOTICE
CHARACTERISTICS
OF THE SUCTION
PIPES
The suction pipe must have the following technical
specifications:
- recommended minimum nominal diameter: ¾”;
- recommended nominal pressure: 10 bar (145 psi);
- use pipes suitable for vacuum operation (e.g. with
metal core)
