6.4.1. Suction pipe
The suction pipe must be perfectly airtight and be
led upwards in order to avoid air pockets.
With a booster set located above the water level
(suction lift operation) fit a foot valve with strainer
which must always remain immersed.
EN
With the liquid level on the suction side above the
booster set (inflow under positive suction head) fit
an inlet gate valve.
6.4.2. Delivery pipe
Fit a gate valve in the delivery pipe.
6.4.3. Diaphragm vessel
A diaphragm pressure vessel must always
be installed on the pump outlet.

Necessary to grant a proper booster set
operation.
It is required to store a certain quantity of water to
feed little consumptions without having the pump
to start.
6.4.4. Pressure relief valve
If necessary the customer must be provide, on
the delivery pipe, a pressure relief valve. The
installation must be provided when the maximum
pump pressure, plus the maximum inlet suction
head, exceeds maximum booster set pressure
or exceed maximum pressure of the remaining
components on the delivery pipes.
The valve must be dimensioned to be able to drain
the flow of booster set at the calculated pressure
point ensuring that pump casing pressure does not
exceed 8 bar.
For the installation of the pressure relief valve refer
to the manuals provided with the valve and local
laws.

6.5. Electrical connection

OFF
Electrical connection must be carried out
only by a qualified electrician in accordance
with local regulations.
Follow all safety standards.
The unit must be properly earthed (grounded).
Connect the earthing (grounding) conductor to the
terminal with the marking.
Compare the frequency and mains voltage with the
plate data and connect the in accordance with the
diagrams.

6.6. Power supply connection

Electrical supply must comply with the description
in section 3.
If the electric control box is connected to an
electric plant with a differential switch (ELCB) or a
Ground Fault Circuit Interrupter (GFCI) as a further
protection, these devices must comply the following
characteristics:
Suitable to control leakage current and, in case of
short pulsed leakage current.
These protections must be signed with the
followings symbol (F-type).
