Pumped liquids

The machine has been designed and made for pumping water, free from explosive substances and solid particles or fibres, with

a density of 1000 Kg/m³, a kinematic viscosity of 1mm²/s and non chemically aggressive liquids.

ENGLISH

The power supply cable must never be used to carry or shift the pump.

Never pull on the cable to detach the plug from the socket.

If the power cable is damaged, it must be replaced by the manufacturer or by their authorised technical assistance service, so

as to avoid any risk.

Failure to observe the warnings may create situations of risk for persons or property and will void the product guarantee.

RESPONSIBILITY

The Manufacturer does not vouch for correct operation of the electropumps or answer for any damage that they may

cause if they have been tampered with, modified and/or run outside the recommended work range or in contrast with

other indications given in this manual.

The Manufacturer declines all responsibility for possible errors in this instructions manual, if due to misprints or errors in copying. The Manufacturer

reserves the right to make any modifications to products that it may consider necessary or useful, without affecting their essential characteristics.

1. GENERAL

The product is an integrated system composed mainly of a self-priming multi-stage centrifugal electropump, an electronic circuit that controls it

and an expansion vessel. Cooling of the motor with water rather than air ensures less noise in the system.

1.1 Applications

Water systems supply and pressure boosting domestic use. On the

outside the product appears as a parallelepiped that presents 6 faces as

hown in Fig.1.

Face B: A rubber cable gland allows the exit of the power cable to be connected to the power mains.

Face C: the 4 brass threads form the seat for the 4 support feet in the case of vertical installation. The two 1” screw caps can be removed to make

the connections towards the system, depending on the installation configuration you want to adopt. If applicable, connect to the connection marked

ENGLISH

“IN” the system from which you want to draw water (well, cistern,…) and connect the delivery system to the connection marked “OUT”. There is

also a ventilation grid. The 3/8” cap allows drainage of the system in the case of horizontal installation. There is also a ventilation grid.

Face E: the 4 brass threads form the seat for the 4 support feet in the case of horizontal installation. The main function of the 1” cap is drainage

of the system in the case of vertical installation. There are also 2 ventilation grids.

Face F: as indicated by the label to be removed, the 1” cap next to the word “IN” on face C has a dual function: in the case of horizontal installation,

the outlet that is closed by the cap acts as the system’s loading door (see below “loading operations”, par. 2.2.3); in the case of vertical installation,

the same outlet can act as the input hydraulic connection (exactly like the one marked “IN” on face C and as an alternative to it). The other 1” cap

gives access to a second delivery connection that can be used at the same time as or alternatively to the one indicated with “OUT” on face C. The

user interface panel is composed of a display and a keyboard and its function is to set the system, query its status and communicate any alarms.

The door closed by 2 screws gives access to a special maintenance compartment: cleaning of the non-return valve and resetting of the tank

preload pressure.

The system can be installed in 2 different configurations: horizontal (Fig.4) or vertical (Fig.5).

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 and indicate them. The Inverter control ensures different functions, the most important of which, for pumping systems, are

the maintaining of a constant pressure value in delivery and energy saving.

• The inverter is able to keep the pressure of a hydraulic circuit constant by varying the rotation speed of the electropump. In operation without

an inverter the electropump is unable to modulate and, when there is an increase of the request for flow, the pressure necessarily decreases,

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 varying the rotation speed according to the instantaneous request of the utility, the inverter limits the power supplied to the electropump to

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 total capacity of 1 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 reserve which, in the case of small leaks, maintains the pressure in the system for a longer time and spreads out 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 expansion vessel to ensure a water reserve such as to reduce interventions of 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).

The expansion vessel is preloaded with pressurised air through the valve accessible from the special maintenance compartment (Fig.1, Face F).

The preload value with which the expansion vessel is supplied by the manufacturer is in agreement with the parameters SP and RP set as 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

equation is satisfied again (e.g.: SP=2.0bar; RP=0.3bar; release air from the expansion vessel until a pressure of 1.0 bar is reached on the valve).

ENGLISH

Failure to respect the above equation may lead to malfunctions of the system or to premature breakage of the diaphragm inside

the expansion vessel.

Considering the expansion vessel capacity of only 1 litres, any operation to check the air pressure must be performed by connecting

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 pressure value, proceed to check it only at

calibration or if you 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 it open until it no longer gives any water.

The special structure of the expansion vessel ensures its quantity and duration over time, especially of the diaphragm which is

typically the component subject to wear for items of this type. However, in the case of breakage, the entire expansion vessel must

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.

The system is designed to be able to work in environments where the temperature remains between 1°C and 50°C (on condition

that the electric 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

management of 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.

The installation of a filter on intake causes a decrease of the system’s hydraulic performance proportional to the loss of load caused

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.

• The distance of at least 10mm between Face E of the system and any

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 from the system, leave a further distance sufficient to manoeuvre

the drainage cap.

• The distance of at least 10mm between Face B of the system and

an obstruction is obligatory to let out the power supply cable to the

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 surface is 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 not be in an inclined position.

2.1.1 Hydraulic connections

Make the connection at input to the system through the mouth on Face F marked “IN” in. Fig.6 (suction connection). Then remove the cap using

a screwdriver.

Make the connection at output from the system through 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

Figure 7

The brass threads are housed in technopolymer seats. When making the connection watertight by 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).

If the vertical installation of the system is of the “over head” type, it is recommended to fit a non-return valve in the suction section

of the system; this is to allow the operation of loading 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 way as 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 (recommended in paragraph

2.1.1) has been placed close to the system entry door, the quantity of water with which to fill the system should 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 - Horizontal Configuration

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 distance of at least 10mm between Face B of the system and

an obstruction is obligatory to let out the power supply cable to the

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 surface is 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 not be in an inclined position.

2.2.1 Hydraulic connections

Make the connection at input to the system through the mouth on Face C marked “IN” in Fig. 8 (suction connection). Then remove the cap using

a screwdriver. Make the connection at output from the system through 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 it can be connected are of the threaded female type 1” GAS, made of brass.

See WARNING for Fig.7.

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 it to be rotated from 90° to 90° (Fig.9).

Figure 9

• Disengage the 4 screws at the corners of the panel using the accessory tool.

• Do not remove the screws completely, just disengage them from the thread on the product body.

• Be careful not to drop the screws into the system.

• Move the panel away, taking care not to pull on the signal transmission cable.

• Reposition the panel in its seat at the preferred angle taking care not to pinch the cable.

Tighten the 4 screws with the wrench.

2.2.3 Loading Operation - Installation above head and below head

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).

Installation “above head”: with a screwdriver, remove the filling cap which, for the horizontal configuration, is the one on Face F (Fig.1). Fill the system

with clean water through the loading door, taking care to let the air out: to ensure optimum filling it is convenient to open also the loading door on Face

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 to close

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 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 loose). 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.

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 it and 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 product contains 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 SP and 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 default configuration

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

The priming of a pump is the phase during which the machine attempts to fill the body and the suction pipe with water. If the operation is successful

the machine can work regularly.

ENGLISH

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 electric power supply

after having opened at least 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 pressed the 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 which are 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 than 1” and that it is well sealed (with no holes or joins from which it can take in air), the product has been studied to manage to prime in

water conditions up to 8m in depth in a time of less than 5 minutes. As soon as the product detects a regular flow in delivery, it leaves the 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, wait 10 minutes and repeat the procedure from the moment you put the plug in the socket.

Press “˅“ to confirm that you do not want to start the 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.

Figure 12

The MODE key allows you to move on to the next items in the same menu. Holding it down for at least 1 sec allows you to skip

to previous menu item.

The SET key allows you to leave the current menu.

Decreases the current parameter (if it is an editable parameter).

ENGLISH

Increases the current parameter (if it is an editable parameter).

Table 5

Holding down the “˄” key or the “˅” key allows the automatic increase/decrease of the parameter selected. After the “˄” key or the “˅” key has

been held down for 3 seconds, the automatic increase/decrease speed increases.

When the ˄ key or the ˅ key is pressed the selected value is modified and saved immediately in the permanent memory (EEprom).

If the machine is switched off, even accidentally, in this phase it does not cause the loss of the parameter that has just been set.

The SET key is only for leaving the current menu and is not necessary for saving the changes made. Only in particular cases

described in the following paragraphs are some values updated by pressing “SET” or “MODE”.

Warning leds

possible to change them. The password management system is in the “technical assistance” menu and is managed by means of the parameter PW.

4.6 - Enabling and disabling the motor

In normal operating conditions, pressing and then releasing both the “˄” and “˅” keys causes the blocking/release of the motor (self-holding even after

switching off). If there is a fault alarm, the operation described above resets the alarm. When the motor is disabled this status is shown by the blinking

white LED. This command can be activated from any menu page except RF and PW.

5. MEANING OF THE INDIVIDUAL PARAMETERS

The inverter makes the system work at constant pressure. This regulation is appreciated if the hydraulic plant downstream from

the system is suitably sized. Plants made with pipes with too small a section introduce load losses that the equipment cannot

compensate; the result is that the pressure is constant on the sensors but not on the utility.

Plants that are excessively deformable can create the onset of oscillations; if this occurs, the problem can be solved by adjusting

the control parameters “GP” and “GI” (see par 5.6.3 - GP: Proportional gain coefficient and 5.6.4 - GI: Integral gain coefficient)

5.1 User Menu
