5 PROPER USE OF THE PRODUCT
The vacuum unit has been designed to be installed for the pneumatic transport of pellets or
other biomass fuels with a medium-fine size;
it can move a large amount of air into the pipes connected, allowing the solid fuel to be
transported together with the air.
This product is suitable for working with biomass fuel such as pellets, olive pomace,
crushed shells of dried fruit, corn, but it cannot work with fuels having a very fine
size, or having excessive dimensions and, in any case, having lengths over 40 mm or
diameter greater than 15 mm.
It is recommended to use only ENplus A1 certified pellet.
The vacuum unit must be installed above the boiler tank.
It is equipped with a panel for the regulation and the control of all the system functions
of the fuel pneumatic transport: this panel can be controlled directly from the boiler, if the
manufacturer has provided it (see boiler use manual).
The vacuum unit moves the fuel from the main storage tank to the boiler tank on which it has
been installed continuously and automatically; it is already equipped with a dispenser and all
the systems for the adjustment and the operation safety.
The product is suitable to serve boilers with a maximum power of 100 Kw/h and with a fuel
consumption lower than 25 kg/h.
6 INSTALLATION
It is the installer’s responsibility to verify the presence of any risk of danger in the
installation area and to determine the suitability in accordance with both the applicable
laws and the product characteristics described in this manual.
The installer must also comply with the requirements of this manual as well as inform the user
of the operation and maintenance of the installed products and report any dangers related
to their use.
It is necessary to leave a free space of adequate size all around the product, in order to permit
any repair, maintenance or inspection operation.
The product should not be exposed to atmospheric agents and should not be installed in
areas subject to high humidity, possible flooding, high temperatures and dust presence.

6.2 Positioning
To fix the vacuum unit on the boiler tank follow these cautions:
a) it must be firmly fixed and leveled above the tank loading mouth
b) it does not hinder any manual filling of the tank
c) the dispenser discharge outlet must be inside the tank or at least at the level of the boiler tank lid
d) the dispenser discharge outlet should possibly be located in the center of the tank
e) the dispenser discharge flap must be free to move completely and does not hit anything during its
movement.
6.1 INSTRUCTIONS FOR INSTALLING THE SYSTEMS
Consider that in pneumatic fuel transport systems there are two different types of pipe features:
- sections of pipes where only air and eventually dust pass through
B- sections of pipes where both air and fuel pass through
Mandatory all sections of piping through which the fuel passes must be made with PU or steel pipe and they
must be connected to be antistatic.
We remind you that the lengths of the various pipe sections described in our manuals and catalogs are purely
indicative: when we speak of “available length” we mean the total development of the various sections.
It is always advisable to make mainly straight and horizontal piping sections and, in any case, with the least
number of changes of direction and vertical paths.
For all the sections where fuel passes, it is recommended to follow these simple rules:
the maximum length allowed for the various sections of piping depends on the components chosen for your
system:
1 - the characteristics and technical data provided for each component must always be evaluated in advan-
ce, so that the system works at its best and has the required characteristics.
2 - in two-pipe systems (fuel suction and air return to the silo) the limits on the lengths are generally much
lower and never exceed 10 meters. With some products pipe lenght cannot be more than 3 meters.
3 - in single-pipe systems, the maximum length allowed for the various sections of pipe, despite being limited
by the components chosen for your system, is more generous, but even in these cases it is necessary to
evaluate in advance the characteristics and technical data provided for each component installed.
4 - paths with many curves or with very close curves should always be avoided.
5 - the minimum radius of the curves must be equal to or greater than 0.5 meters.
6 - sections of pipes that include both positive and negative siphons must be avoided.
7 - the sections of horizontal pipes must be kept perfectly leveled.
8 - vertical pipe sections longer than 3.5 meters must always be avoided and at the bases of these the mini-
mum radius of the bends must be equal to or greater than 1 meter
9 - the sections of piping where fuel passes must be well fixed at least every 1.5 meters.
It is recommended to use only pipes, fittings and accessories present in our catalog, as they have been
designed, tested and built specifically for these systems.
Before installation and start-up of the system, it is essential to carefully read the instructions supplied with
the various components and in case of doubts it is advisable to contact specialized personnel.
The realization of the systems and the installation of the components must always meet the safety
standards corresponding to the type of rooms in which they are positioned.

31/05/2021 Rev:1.0.4
6.3 Warning for installations on controlled pressure tanks
It is important to remind that pneumatic transport systems work modifying the state of pressures
in the different components of the installation itself: in particular, during the functioning of our
systems, the negative pressure inside the dispenser ranges from 0,080 to 0,24 bar (-1,16 to -3,48
psi).
Note: when the system is starting, an air suction from the pellet discharge flap placed on the
bottom of the dispenser may occur.
Afterwards, the same may happen during the dispenser filling phase, due to small wood particles
snagged between the fuel outlet and the lower closing flap, which impede the perfect sealing.
These leakages don’t prejudice the system operation, but they could change the negative
pressure inside the boiler tank, with a risk for boiler safety.
Is it possible to fix the situation mainly by programming the working time of the fuel transfer
system only when:
A) The brazier of the boiler is switched off and cold
B) The loading door of the tank is open
C) The communication channel between the fuel tank and the boiler brazier is completely closed
D) The smoke extraction fan of boiler is working at the max power;
E) On the boiler tank is present an electrical valve, with proper dimensions, connected to the fuel
feeding transport system, which allows an easy compensation of the air sucked.
12 3
To facilitate these operations, the vacuum unit is supplied with a template for preparing the
holes.
See figures 1 to 3.
Where it is not possible to place the dispenser discharge outlet inside the tank, a maximum level
sensor must be installed in the tank, connecting it to the panel which controls the system, to
prevent fuel leaks during the loading cycles.

6.3 Connection to the piping network
Both the Ø 50 mm pipes of the vacuum unit must be connected with at least one piece of
antistatic flexible hose with equal diameter, secured with well-fixed hose clamps.
The other end of the antistatic pipe should be connected to the rest of the fuel transport system,
which can still be made with flexible antistatic pipe or steel pipes, also present in the catalogue.
To avoid static currents, the copper strand in the antistatic pipe must always be in contact with
a grounding or other steel pipes belonging to the fuel transport system.
The OUT pipe exhausts dusty air from the central vacuum unit, while the IN pipe transports the
fuel to the unit dispenser.
The air exhaust pipe can be connected with a fuel extraction accessory where provided;
otherwise, it should be connected to the dust collectors present in the catalogue. The maximum
allowed gross length between the fuel withdrawal point and the central vacuum unit is 25 m.
The following elements affect the calculation of the net length of the pipe:
- the type of fuel to be conveyed
- the number of curves inserted in the section where the fuel passes
- the length of the vertical paths inserted in the section where the fuel passes
The maximum allowed length of the exhaust pipe (expulsion) of the air exiting the central unit
is 5 m (single-pipe system)
The maximum allowed length of the air expulsion pipe exiting the central unit, if it returns to the
fuel withdrawal point, is 10 m (double pipe system)
See “system technical data” on our website
6.4 Electrical Connection
Before making the electrical connection, check that the supply voltage corresponds to
the one required and that the electrical system to which the product is connected is
done in compliance with current regulations.
Connect the two wires of the activation line called AUX to the motorized extraction system (if
present).
Check that the two operation consent wires, labeled MICRO, are connected together.
Alternatively, the two wires called MICRO can be connected
- to the control system of the boiler if the latter is predisposed for this.
- to a timer in order to program the operating times
- to a remote automatic activation system
- to a level sensor (see our catalog)
Connect the power cable to a 230 V ac power outlet.

Before proceeding to unit start up, it is opportune to check that the pipes are correctly and firmly fixed
to it, and that electrical connections comply with the current law, as well as the electric system to which
it is connected.
Prepare an empty run to verify the functionality and then, before filling with fuel the storage tank, check
that there are no foreign bodies inside it.
Read all the manuals of the different components of the system before proceeding.
Removethe timerprotective capand turnthepotentiometer anti-clockwisewith ascrewdriver,positioning
it on OFF mode.
Place the main switch over the control panel to 1.
The green “POWER” led on the control panel lights up.
Turn the potentiometer slightly clockwise and wait for the central unit to begin operations and complete
a brief operating cycle.
Adjust the potentiometer at this point, so that the operation time of the central unit is sufficient to fill the
transparent dispenser with fuel till the level indicated by the “MAX LEVEL” adhesive label.
After a few successful operating cycles, refit the protective cap.
In the case of fillings at a lower level there can be no consequences, but fillings far superior to the
optimum level could cause defects and noise in vacuum unit functioning and occlusions in fuel transport
pipes.
It is therefore advisable to adjust the operating times properly, taking care to check them at least at each
refilling of the fuel storage tank.
Now the vacuum unit is operational: an additional potentiometer adjustment may be necessary if you
change, even a little bit, the specific weight or type of the fuel which has to be transported. In these
cases, it is sufficient to readjust the operating time of the vacuum unit so that it is appropriate to fill the
transparent fuel dispenser, at each cycle, to the level indicated by the “MAX LEVEL” adhesive.
If the unit will remain inoperative for a long time, place the light switch on 0 and remove the power supply.

7.1 Alarm light
The control panel of vacuum unit has a red led called “ALARM”: in the case it is illuminated,
the unit and consequently the fuel transport system stop. This blockage may be due to
various causes. The most frequent are:
A - Lack of fuel in the storage tank.
B - Ablockage in the fuel transport pipe does not allow the fuel flow in the dispenser.
C - The fuel inlet pipe is not airtight, so the air suction does not allow the fuel flow into the
dispenser.
D - The fuel discharge door of the dispenser does not close tightly, so there is an air suction
which does not allow the correct flow of the fuel in the dispenser.
In all these cases, after the vacuum unit has run three cycles without fuel suction, the failure
red led will turn on and the vacuum unit will no longer operate until manual reset.
Manual reset to eliminate the alarm should be done after solving the problem that produced
the block: the necessary operation is made by turning the illuminated switch 0-1 off and, after
10 seconds, turning it newly on.
7.2 Thermal switch
The thermal switch’s task is to protect the electrical and electronic parts of the vacuum cleaning
unit from overcurrents and short circuits.
The button of the switch during correct operation will be positioned inside its own seat, while in
the event of a successful protection the button will be released from its seat.
The reset must be done manually by pressing the button, this operation will be effective only if
the cause of the block has been solved.
If blocking occurs repeatedly, the intervention of a specialized technician is necessary.
