1.2 Description of the Integrated Inverter
The electronic control integrated in the system is of the type with inverter and it makes use of flow, pressure and temperature sensors, also
integrated in the system.
By means of these sensors the system switches on and off automatically according to the utility’s needs and it is able to detect conditions of
malfunction, to prevent andindicatethem. The Inverter controlensuresdifferentfunctions, themost important of which,for pumpingsystems,are
the maintaining of a constant pressure value in delivery and energy saving.
•The inverteris able to keepthe pressureof a hydrauliccircuit constantby varying the rotation speed of the electropump.In operation without
an inverterthe electropumpis unableto modulateand, when thereis an increaseof the requestfor flow, the pressure necessarilydecreases,
or vice versa; this means the pressures are too high at low flow rates or too low when there is an increased request for flow.
•By varyingthe rotation speedaccordingto the instantaneousrequestof the utility,the inverter limits the power supplied to the electropumpto
the minimum necessary to ensure that the request is satisfied. Instead, operation without an inverter contemplates operation of the
electropump always and only at maximum power.
or the configuration of the parameters see chapters 4-5.
1.3 Integrated Expansion Vessel
The system is complete with an integrated expansion vessel with a totalcapacity of1 litres. The main functions of the expansion vessel are:
•to make the system elastic so as to protect it against water hammer;
•to ensure a water reservewhich, in the caseof smallleaks, maintains the pressurein the systemfor a longer time and spreadsout needless
restarts of the system which otherwise would be continuous;
•when the utility is turned on, ensure the water pressure for the seconds that the system takes to switch on and reach the correct rotation
speed.
It is not a function of the integrated expansionvesselto ensurea waterreserve suchas to reduceinterventionsof the system(requests from the
utility, not from a leak in the system). It is possible to add an expansion vessel with the capacity you prefer to the system, connecting it to a point
on the delivery system (not a suction point!). In the case of horizontal installation it is possible to connect to the unused delivery outlet. When
choosing the tank, consider that the quantity of water released will also depend on the parameters SP and RP that can be set on the system
(chapters 4-5).
Theexpansionvessel is preloaded withpressurisedair throughthevalveaccessiblefromthespecialmaintenancecompartment(Fig.1,Face F).
The preloadvaluewith whichthe expansionvesselis suppliedby the manufactureris inagreementwith the parametersSPand RPsetas default,
and anyway it satisfies the following equation:
Pair = SP – RP – 0.7 bar Where:
- Pair = air pressure value in bar
- SP = Set Point (chapter 5.3.1) in bar
- RP = Reduction of pressure to restart (chapter 5.5.1) in bar
So, by the manufacturer: Pair = 3 – 0.3 – 0.7 = 2.0 bar
If different values are set for the parameters SP and/or RP, regulate the valve of the expansion vessel releasing or letting in air until the above
equationis satisfied again(e.g.: SP=2.0bar; RP=0.3bar; release air fromthe expansionvesseluntil apressureof 1.0 baris reachedon the valve).

ENGLISH
39
Failure to respect the above equation may lead to malfunctions of the system or to premature breakage of the diaphragm inside
the expansion vessel.
Consideringtheexpansionvesselcapacityofonly1litres,anyoperationtochecktheairpressuremustbeperformedbyconnecting
the pressure gauge very rapidly: on small volumes the loss of even a limited quantity of air can cause an appreciable drop in
pressure. The quality of the expansion vessel ensures the maintenance of the set air pressurevalue, proceed to check it only at
calibration or ifyou are sure of a malfunction.
Any operation to check and/or reset the air pressure must be performed with the delivery system not under pressure:disconnect
the pump from the power supply and open the utility nearest to the pump, keeping itopen until itno longer gives any water.
The special structure of the expansion vessel ensures its quantity and duration over time, especially of the diaphragm which is
typicallythe component subject to wear for items of this type. However,in the case of breakage,the entire expansion vesselmust
be replaced and exclusively by authorised personnel.

2. INSTALLATION
The system is designed for indoor use: do not install the system outdoors and/or directly exposed to atmospheric agents.
Thesystemisdesignedtobeabletoworkinenvironmentswherethetemperatureremainsbetween1°Cand50°C(oncondition
thattheelectric power supply is ensured:see par.5.6.8 “anti-freeze function”). Esybox mini operates correctly with a difference
between ambient and liquid temperatures of no more than 30°C (with the ambient temperature higher than the liquid
temperature). Besides this temperature difference, the humidity limit must not exceed 50%, otherwise there is a risk of
condensation forming,which can cause irreparable damage to the electronic board.

ENGLISH

The system is suitable for treating drinking water.
The system cannot be used to pump salt water, sewage, inflammable, corrosive or explosive liquids (e.g. petroleum, petrol,
thinners), greases, oils or food productsi.
The system can suck up water with a level that does not exceed the depth of 8 m (he height between the water level and the
pump suction mouth).
If the system is used for the domestic water supply, respect the local regulations of the authorities responsible for the
managementof water resources.
When choosing the installation site,check that:
•The voltage and frequency on the pump’s technical data plate correspond to the values of the power supply system.
•The electrical connection is made in a dry place, far from any possible flooding.
•The earth system must comply with the regulations.
The possible presence of a small amount of water inside the product is a residue of the testing process.
If you are not sure of the absence of foreign bodies in the water to be pumped, install a filter on the system intake that is suitable for catching
impurities.
Theinstallationof afilter onintakecausesadecreaseof thesystem’shydraulicperformanceproportionaltothelossof loadcaused
by the filter itself (generally the greater the filtering power, the greater the fall in performance).
Choose the type of configuration you intend to use (vertical or horizontal) considering the connections to the system, the position of the user
interface panel, and the spaces available according to the indications below.Wall installation is possible, see par.8.2.
2.1 - Vertical Configuration
Screw the 4 rubber feet supplied loose in the package into the brass
seats in face C. Put the system in place, taking into account the
dimensions in Fig.6.
•Thedistanceofatleast10mmbetweenFaceEofthesystemandany
wall is obligatory to ensure ventilation through the grids provided. If
you expect to have to drain the system from its discharge door and
not fromthe system,leave a further distance sufficient to manoeuvre
thedrainage cap.
•The distanceof at least 10mm betweenFace B of thesystem and
anobstructionisobligatorytoletoutthepowersupplycabletothe
mains socket.
•The distance of at least 200mm between Face A of the system
and an obstruction is recommended so as to be able to remove
the door and gain access to the technical compartment.
Figure 6
If the surfaceis not flat, unscrewthe foot that is nottouching and adjust its height untilit contacts the surface so as to ensurethe stability of the
system. The system must in fact be placed in a safe and stable position, ensuring that its axis is vertical:it must notbe in an inclined position.
2.1.1 Hydraulic connections
Make the connectionat input to the systemthrough the mouth on Face F marked“IN” in.Fig.6 (suction connection). Then removethe cap using
a screwdriver.
Make the connectionat output from the systemthrough the mouth on Face F marked “OUT” in Fig.6 (delivery connection). Then remove the cap
using a screwdriver.
All the hydraulic connections of the system to the plant to which it can be connected are of the threaded female type 1” GAS,made of brass.
If you intend to connect the product to the plant with fittings that have a diameter larger than the normal 1” pipe (for example
the ring nut in the case of fittings in 3 pieces), make sure that the 1” Gas male thread of the coupling protrudes at least 25mm
from the above diameter (see Fig.7)

ENGLISH
41
Figure 7
Thebrassthreadsarehousedin technopolymerseats.When making theconnectionwatertightby adding material(e.g.Teflon,
hemp,...) ensure that the gasket is not too thick: under the action of an adequate tightening torque (e.g. long handled pipe
wrench), the excess material could exert abnormal force on the technopolymer seat, damaging it irremediably.
With reference to its position with respect to the water to be pumped, the installation of the system may be defined “above head” or “below head”. In particular
the installation is defined “above head” when the pump is placed at a level higher than the water to be pumped (e.g. pump on the surface and water in a well);
vice versa it is “below head” when the pump is placed at a level lower than the water to be pumped (e.g. overhead cistern and pump below).
Iftheverticalinstallationofthesystemisofthe“overhead”type,itis recommendedtofitanon-returnvalveinthesuctionsection
of the system; this is to allow the operation ofloading the system (par. 2.1.2).
If the installation is of the “over head” type, install the suction pipe from the water source to the pump in such a wayas to avoid the
formation of goosenecks or siphons. Do not place the suction pipe above the pump level (to avoid the formation of air bubbles in
the suction pipe). The suction pipe must draw at its entrance at a depth of at least 30cm below the water level and must be watertight
along its whole length, as far as the entrance to the electropump.
The suction and delivery pipes must be fitted so that they do not exert any mechanical pressure on the pump.
2.1.2. Loading Operation - Installation above head and below head
Installation “above head” (par. 2.1.1): access the technical compartment and, using a screwdriver,remove the filling cap (Fig.3). Fill the system
with clean water through the loading door, taking care to let the air out. If the non-return valve on the suction pipe (recommendedin paragraph
2.1.1) has been placed close to the system entry door, the quantity of water with which to fill the systemshould be 0,9 litres. It is recommended
to fit the non-return valve at the end of the suction pipe (foot valve) so as to be able to fill it quickly too during the loading operation. In this case
the quantity of water necessary for the loading operation will depend on the length of the suction pipe (0,9 litres + …).
Installation “below head” (par. 2.1.1): if there are no check valves between the water deposit and the system (or if they are open), it loads automatically
as soon as it is allowed to let out the trapped air. So slackening the filling cap (Fig.3) enough to vent the trapped air allows the system to load
completely. You must survey the operation and close the loading door as soon as the water comes out (however it is recommended to fit a check
valve in the section of the suction pipe and to use it to control the loading operation with the cap open). Alternatively, in the case where the suction
pipe is intercepted by a closed valve, the loading operation may be carried out in a similar way to the one described for installation over head.
2.2 - HorizontalConfiguration
Screw the 4 rubber feet supplied loose in the package into the brass
seats in face E. Put the system in place, taking into account the
dimensions in Fig.8.
•The distanceof at least 10mm betweenFace B of thesystem and
anobstructionisobligatorytoletoutthepowersupplycabletothe
mains socket.
•The distance of at least 200mm between Face A of the system
and an obstruction is recommended so as to be able to remove
the door and gain access to the technical compartment.
Figure 8
If the surfaceis not flat, unscrew the foot that is not touching and adjust its height until it contacts the surface so as to ensure the stability of the
system. The system must in fact be placed in a safe and stable position, ensuring that its axis is vertical:it must notbe in an inclined position.
2.2.1 Hydraulic connections
Make the connectionat input to the systemthrough the mouth on Face C marked “IN” in Fig. 8 (suction connection). Then remove the cap using
a screwdriver.Make the connection at output fromthe systemthrough the mouth on Face C marked “OUT 1” in Fig. 8 and/or through the mouth
on Face F marked “OUT 2” in Fig. 8 (delivery connection).
In this configuration either of the 2 mouths can be used as an alternative to the other (depending on the convenience of the installation), or
simultaneously (dual delivery system). Then remove the cap(s) from the door(s) you intend to use with a screwdriver.
All the hydraulic connections of the system to the plant to which itcan be connected are of the threaded female type 1”GAS, made of brass.
See WARNING for Fig.7.

2.2.2 Orientation of the Interface Panel
The Interface Panel has been designed so that it can be oriented in the direction where it is most convenient for the user to read: its square
shape allows itto be rotated from 90° to 90° (Fig.9).

2.2.3 Loading Operation - Installation above head and below head
With referenceto its positionwith respect to the waterto be pumped,the installation of the system may be defined “above head”or “below head”.
In particular the installation is defined “above head” when the pump is placed at a level higher than the water to be pumped (e.g. pump on the
surface and water in a well); vice versa it is “below head” whenthe pump is placed at a level lower than the water to be pumped (e.g. overhead
cistern and pump below).
Installation “above head”: with ascrewdriver, remove thefilling capwhich, for the horizontal configuration, isthe oneon Face F (Fig.1). Fill the system
with clean waterthrough the loading door, taking care to letthe air out: to ensure optimum filling it is convenient to open also the loading door onFace
A (Fig.1), used for filling in the vertical configuration, so as to let all the air out, which otherwise could remain trapped in the system; take care toclose
the openings correctly once the operation is completed. The quantity of water with which to fill the system must be at least 0,7 litri almeno. litres. It is
recommended to fit a non-return valve at the end of the suction pipe (foot valve) so as to be able to fill it quickly too during the loading operation. In
this case the quantity of water necessary for the loading operation will depend on the length of the suction pipe (0,7 litres + …).
Installation “below head”: if there are no check valves between the water deposit and the system (or if they are open), it loads automatically as
soon as it is allowed to let out the trapped air. So slackening the filling cap (Face F - Fig.1) enough to vent the air allows the system to load
completely.You must survey the operation andclose the loading door as soon as thewater comes out (however it is recommended to fit a check
valveinthesectionofthe suctionpipe andto useitto control the loading operation with the cap loose). Alternatively, in the case where the suction
pipe is intercepted by a closed valve,the loading operation may be carried outin a similar way to the one described for installation over head.
3. COMMISSIONING
The suction depth must not exceed 8 m.
3.1 Electrical Connections
To improve immunity to the possible noise radiated towards other appliances it is recommended to use a separate electrical duct to supply the
product.
The line voltage may change when the electropump is started. The line voltage may undergo variations depending on other
devices connected to itand on the quality of the line.
It is recommended to carry out installation as indicated in the manual, in compliance with the laws, directives and standards in
force in the place of use and depending on the application.
The productcontains an inverter inside which there are continuous voltages and currents with high-frequency components (see Table 2).

3.2 Configuration of the Integrated Inverter
The system is configured by the manufacturer to satisfy most installation cases operating at constant pressure.The main parameters set in the
factory are:
•Set-Point (desired value of constant pressure) SP = 2.7 bar / 39 psi.
•Reduction of pressure to restart RP = 0.3 bar / 4.3 psi.
•Anti-cycling function: Disabilitata.
However, these parameters and others can be set by the user according to the system.See par. 4-5 for the specifications.
For the definition of the parameters SPand RP, the pressure at which the system starts has the value:
Pstart = SP – RP For example:2.7 – 0.3 = 2.4 bar in the defaultconfiguration
The system does not work if the utility is at a height higher than the equivalent in metres of water column of the Pstart (consider 1 bar = 10 m
water column): for the default configuration, if the utility is at a height of at least 27m the system does not start.
3.3 -Priming
Theprimingofapumpisthephaseduringwhichthemachineattemptsto fillthebodyandthesuctionpipewithwater.Iftheoperationissuccessful
the machine can work regularly.

ENGLISH
44
Once the pump has been filled (par. 2.1.2, 2.2.3) and the device has been configured (par. 3.2), it is possible to connect the electricpower supply
after having opened atleast one utility on delivery for the first 10 seconds.
If a flow of water is detected in delivery, the pump is primed and starts its regular work. This is the typical case of installation below head (par.
2.1.2, 2.2.3). The utility opened in delivery from which the pumped water is coming out can be closed.
If a regular flow in delivery is not detected after 10 seconds, the system asks for confirmation to enter the priming procedure (typical case of
installation above head par.2.1.2, 2.2.3). Or:
Figure 11.1: Priming PopUp (1) Figure 11.2: Priming PopUp (2)
When “˄” is pressedthe pump enters the priming procedure:it starts working for a maximum time of 5 minutes during which the safety block for
dry operation is not tripped.The priming time depends on various parameters,the most influential of whichare the depth of the water level from
which it is drawing, the diameter of the suction pipe, the water-tightness of the suction pipe. On condition that a suction pipe is used that is no
smaller than1” and that it is well sealed (with no holesor joins from which it can take in air), the product has been studied to manage to prime in
waterconditions upto 8m in depthin a time of lessthan 5 minutes.As soonas the productdetects a regularflow in delivery, it leavesthe priming
procedure and starts its regular work. The utility opened in delivery from which the pumped water is coming out can be closed. If after 5 minutes
of the procedure the product is still not primed, the interface display sends a failure message. Disconnect the power supply, load the product
adding new water, wait10 minutes and repeat the procedure fromthe moment you put the plug in the socket.
Press “˅“ to confirm that you do notwant to startthe priming procedure. The product remains in alarm status.
Operation
Once the electropump is primed, the system starts regular operation according to the configured parameters: it starts automatically when the tap is
turned on, supplies water at the set pressure (SP), keeps the pressure constant even when other taps are turned on, stops automatically after time
T2 once the switching off conditions are reached (T2 can be set by the user, factory value 10 sec).
4. THE KEYPAD AND THE DISPLAY
The user interface is composed of a keypad with 320x240 pixel LCD
display and with POWER, COMM, ALARM warning leds as can be
seen in Fig.12.
The display shows the values and the statuses of the device, with
indications on the functionality of the various parameters.
The functions of the keys are summed up in Table 5.
