stop.
6.3.5 Automatic mode
This mode allows an automatic setting of the

7. Installation
7.1 Local
Install the booster in a room that provides an
easy access, well ventilated and frost-proof.
Be sure that the dimension of the technical room
door is adequate to enter a booster.
Adequate space must be provided for mainte-
nance work. An easy access to the installation
shall be ensured from at least two sides.
7.2 Assembling
Assembling on well smooth and horizontal floor
with fixing per foundation bolts. Plan insulating
material (cork or reinforced rubber) under the
concrete pad to avoid any emission of water cir-
culating noise.
7.3 Hydraulic connection
ATTENTION! Observe the requirements from the
water supply companies and the local rule into
force.
- The connection of the suction and delivery mani-
folds can be made either on the right or left hand
sides of the installation. It is recommended to
close the ports that are not used with thread caps.
- Valves must be fitted on the manifolds to easily
separate the booster if need be.
- The installation must be fitted with at least one
diaphragm pressure tank to be assembled on the
delivery manifold, 18 and 24 litre capacities, just
beside the booster for higher capacities.
- The existing pipes must be installed free from
stresses. Compensators or flexible connecting
pipes are recommended for this purpose in order
to avoid stresses on the pipe connections and
minimise the transmission of vibrations to the
building installation.
Connection to public water supply
Be sure the installation can withstand the maxi-
mum pump pressure at zero flow plus the public
water mains pressure. Otherwise connect the
pressure relief valve to the booster outlet.
We recommend to install a pressure relief and
regulating valve on the booster inlet, on the
water supply inlet to avoid any pressure varia-
tions at the booster inlet.

Connection on load to a tank
Be sure the installation can withstand the maxi-
mum pump pressure at zero flow plus the public
water mains pressure. Otherwise connect the
pressure relief valve to the booster outlet behind
the tank.
Connection on suction to a tank
Be sure that the losses of head do not exceed
the suction capacity of the pumps. It is recom-
mended to use a foot-strainer valve with a pipe
whose dimension is equal to or higher than the
suction nominal diameter.
7.4 Electrical connection
WARNING! The electrical connection must be
performed according to the local regulations by
an electrical installation engineer approved by
the local utility.
To make the electrical connection, the corre-
sponding installation and operating instructions
and attached electrical circuit diagrams must be
observed. General points to be considered are
listed below:
• the type of current and voltage of the mains
connection must comply with the data on the
type plate and the circuit diagram of the control
unit.
• as protection measure, the booster must be
earthed according to the regulations (i.e. accord-
ing to the local regulations and circumstances);
the connections intended for this purpose are
identified accordingly (see circuit diagram).
Power supply cable
The electric supply cable shall be correctly
dimensioned according to the total booster
power (see type plate).
Connecting the control box on a voltage differ-
ent from the one mentioned in the description is
not possible (see chapter 5.2. technical data).
NOTA: for any further details an electric diagram
is available inside the control box.
ATTENTION! Do not forget to connect the earth
terminal.
Lack of water protection
An input ON/OFF (250v 2A) (Fig. 6) protects the
booster against lack of water, a pressure switch
(Normally Open) or a float switch shall be con-
nected to this input.
ATTENTION! Do not apply external voltage to
the terminals.
