Chap.1 – General Information
Our pressurization groups must be installed in premises protected against bad weather and frost, well ventilated and
in a non dangerous atmosphere. Each of our groups is entirely tested in our establishments.
Upondelivery, check thatthe group hasnot suffered anydamageduring transportation; inthis case, contactimmediately
the retailer. In case of claims, contact immediately the retailer within eight days of purchase.
Chap.2 – Limits of use
Our pressurization groups are constructed for the raising clean water without solid suspended particles or abrasive
materials.
WARNING The group is not suitable for pumping chemically aggressive or
inflammable liquids.
WARNING Avoidanydry-operatingofthemotorpump.

Chap.3 – Hydraulic installation
DANGER
Risk of electrical
discharge.
All the assembly operations must be carried out with group
disconnectedfrom the power grid.
In the case where the pressurization group is fed by a tank, avoid any unpriming phenomena; we recommend to
control the following characteristic data:
- static level (initial level of the well)
- dynamic level (level reached during the group operation)
- flow rate
Fig.2 shows the assembly diagrams normally used.

DANGER
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless they
have been given supervision or instruction concerning use of the appliance by a person
responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.

13
To reduce losses during replenishment it is necessary to install the group as close as possible to the pumping point
and to install a suction pipe with a minor number of curvatures that should have a sufficiently wide radius.
Even the diameter of the pipe should be calculated so as to reduce load losses, what requires dimensions greater
than or equal to those of the motor pump aspiration inlet.
In order to avoid the formation of air locks into the suction pipes, these ones must have a positive gradient, from
bottom to top, avoiding countergradients or “goosenecks”, and there must not any infiltration in the connections.
Connect the delivery collector to the distribution collector by interposing vibration-damping joint.
This connection can be done either on the right side or on the left side of the collector by displacing the blind flange
or the threaded cover.
WARNING It is a good rule to foresee the evacuation of water losses in case of
bad seal of joints, mechanical seal, tanks overflowing.
In the case where there would not be any pumping in close proximity from the group, on the discharge line, the
installation of a test faucet is recommended.
It is necessary to control from time to time the pre - replenishment pressure of membrane vessel that must be 0.2
bar lower than the minimum closing pressure of the pressure switch calibrated lower.
This control must be done without pressure in the installation or with the tanks disassembled.
Chap.4 – Priming of the group
DANGER

WARNING Thegroup needs to be filledupbefore putting it in operation.Thedry-
operationof the motor pump damagesthe hydraulic parts.
In case of aspiration with upper suction head, open storage, aqueduct or water pipe under pressure, prime the group
as follows:
- open all valves and remove the priming plugs on the aspiration collector and on the motor pumps
- open the water supply on-off valve until the evacuation of the liquid
- close again the feed faucet and the pumping plugs
In the case where the group supply is with lower suction head, underground well or tank, prime the group as follows:
- open all valves and to and remove the priming plugs on the aspiration collector and on the pumps
- fill with water through the suction pipe
- make the necessary topping-up through the priming plugs on the pump casing until complete filling-up
- re assemble the plugs

Protection against the dry-operation of the motor pumps (See fig.6)
On the switchboard it is possible to connect a device for control of the level into the tank. (Our groups are delivered
with jumped terminals 4-5-6)
WARNING In this case the group is not protected against dry-operation. It is
therefore necessary to remove the electric jumpers and to connect
them to the control device chosen as follows:
1) float switch
The float must be installed in the tank and connected thanks to two wires to the special terminals on the control board.
2) electronic control with probes
The three probes should be specially placed in the first collection deposit and should be then connected to terminals
inside the board. The COMMON probe must be installed at the lowest level in the tank and anyway always at a level
lower than the minimum level probe (LOW) that prevents from the working of the pilot pump when water descends
below this level. The maximum level probe (HIGH) allows again the working of the pilot pump when the water reaches
this level.
3) Inverted minimal pressure sensor
In the case where the group is fed by a water duct under pressure (for example municipal water system), it is
necessary to install a minimal pressure sensor which prevents from the working of the group if the pressure in the
duct descends below the preset value.
Chap.6 – Starting up
See fig.3-4-5-6-7-8 and diagrams in the distribution board.
Control of the direction of rotation of the pump with inverter drive.
Once all the hydraulic and electric connections have been done for the hydraulic priming of the pumps and collectors,
proceed as follows:
- close all the valves of the distribution system
- open all the valves of the group, included those of the membrane ways
- control the closing of the distribution board hatch
- place the power supply disconnector on I (ON)
DANGER

Explanation of messages (see fig.6)
1) Lack of water in withdrawal tank
The level control signals the lack of water in the withdrawal tank, or low pressure in the feed duct(aqueduct). At the
same time the red LED - BLOCKAGE LEVEL shall be lit. The same thing occurs in case of false contacts or absence
of level control if the relative terminal have not been short-circuited.
2) Blockage inverter
The inverter is blocked. The reason of the blockage is indicated on inverter display whose manual gives detail of the
position intervened. If the reason is accidental: momentary overcharge of the motor pump (example excessive
request of water), or electric too high or too low voltage, by pushing the RESET key situated on the inverter keyboard,
the system be reset. Otherwise cut the voltage off the switchboard for a few seconds and connect it again. In case
of failure, repeat the operation a second time.
If the blockage persists, it is possible to disable the inverter following the instructions reported in the following
chapter.
3) Thermal blockage
In case one the thermal relays protecting against overcharge or lack of power supply of the motor operating directly
(not controlled by the inverter) is tripped, in addition of the message on the display, the red LED (4) ANOMALY is lit
(the same of INVERTER BLOCKAGE). In this case the programs automatically excludes the pump or pumps that
generated the event and the group operates regularly, even if with a reduced rating. In order to reset, after having
verified the accidental origin of the overcharge, press the resetting lever situated on the thermal relays concerned.

Chap.9–Exclusion of the inverter
In case of breakdown of the inverter, while waiting for the appropriated repair intervention, the group can operates
automatically or manually:
1) Automatic operation
The motor pumps are operated by an SFC card on pressure levels.
In this case it is necessary to cut the voltage off the switchboard and open the protective fuse-holder of the inverter
(see fig.3). It is therefore necessary to increase the value of STOP THRESHOLD following the indications reported
in chap.6 – starting up in point Modification of the working pressure established. The value of SET POINT
represents the startup pressure of the first pump. The one of STOP THRESHOLD indicates the value of stop pressure
of the last pump. The difference between these values must be of at least 1 bar.
Example
SET POINT 5.0 bar
STOP THRESHOLD 6,. bar
If tanks under pressure connected to the delivery collector of the group have a sufficient volume, the installation will
get back in function in the pressure range established (one of pumps, the one that should have been started up
controlled by the inverter will remain in stop). If one observes an abnormal operation (frequent starts up and stops
of pumps) it will be necessary to modify the pressure values established for every pump as described in point 2) of
Chap.7.
2) Manual working (see fig.9)
