following table (applicable for 50 and 60Hz):
By sound pressure level is meant the mean value of the
measurements taken at a distance of 1 m from the set in a free
field. For the noise value tolerance, refer to the manual of the
single main electric pump, as it is the main source of noise.

6.4. TESTING
100% of the pressure booster sets are subjected to routine
hydraulic, mechanical and electrical tests before being
packaged. In particular, the operation of the set and each
individual pump is checked, a seal test is performed with the
delivery outlet closed and the rated head is checked.

HANDLING AND STORAGE
7.1. HANDLING (see the attached diagrams fig. B)
Observe the current accident prevention
regulations.
Possible risk of crushing.
Use safety footwear.
ATTENTION
Only use the procedures specified below and
the lifting points provided for handling the
package and the set after the packaging has
been removed.
The pressure booster sets are sent packaged on wooden
pallets and in a cardboard box for smaller sizes; in the case of
larger sets, in addition to the pallet also a wooden crate is used
and additionally covered with nylon film. In the case of obvious
dimensional problems, the intake manifold can be supplied
disassembled. Various packaging systems (by sea or other)
will be used based on specific customer request.
The set must be handled with utmost caution during handling
and transport. Particular attention must be paid when lifting
and putting down the set:
when the set is on a pallet, move it using a lifting carriage.
Pay attention to the weight indicated directly on the pallet.
Check the stability of the pallet on the lifting carriage
before performing lifting or moving operations;
after the pallet and packaging have been removed, only
use the specific hooking points provided on the base for
movement (note: to lift the set off the pallet, remove the
fastening screws that anchor the set to the pallet itself).
For larger sets, there are 4 eyebolts on the base. For
smaller sets, there are 4 holes on the base for lifting using
pipes (not supplied with the set). It is recommended to
use pipes with a section suitable for lifting and to pay
attention when fastening the lifting belts to prevent the set
from falling. For their movement, take the weight indicated
on the pallet into account. Do not anchor on pumps,
motors, manifolds or other accessories. Make sure that
the set is firmly fixed to the provided lifting points before
performing the lifting and moving operations.
Blows, falls or swinging must be avoided, which could cause
non apparent damage. Do not stand near the set while lifting,
handling or setting it down.
7.2. STORAGE
To maintain the full efficiency of the set:
store the product in a covered and dry location away from
heat sources and protected against impacts, dirt and
vibrations;
do not place heavy objects on the packaging;
store the product at an ambient temperature between
+5°C and +40°C (41°F and 104°F) with a relative humidity
of 60%.
8.
INSTALLATION
Installation must be performed by specialised
and qualified personnel (refer to the definition of
qualified personnel in the INTRODUCTION
chapter).
8.1. MECHANICAL FASTENING (see the attached
diagrams fig. C)
The set must be positioned on a flat surface (refer also to
the TECHNICAL CONSTRUCTION CHARACTERISTICS
chapter for the characteristics required for the installation
environment).
The set must be positioned in a protected area with
reserved access where there is sufficient space for
maintenance and removal. It is recommended to maintain
at least three sides free, i.e. the side of the electric control
panel or protection panel (minimum 100 cm of free
space), the side opposite of the panel and the side with
the connections to the delivery and intake lines (minimum
50 cm of free space).
If the set is provided with feet, the set must be placed on
the ground.
The set arrives with the feet disassembled. The
feet must be assembled with the set lifted off
the ground. Therefore pay utmost attention
during this operation to keep the set from
falling.
Use appropriate PPE.
If the set does not have feet, it can be fixed to the ground
by means of anchors using the provided holes.
8.2. CONNECTION TO THE HYDRAULIC SYSTEM (see
the attached diagrams fig. D)
Refer to the images to identify the referenced points (“a”,”b”…).
The pipes must be sized to support the
maximum operating pressure of the set
(CHECK THE PUMP PRESSURE ON THE
PUMP
PLATE
TO
DETERMINE
THE
MAXIMUM PRESSURE AT WHICH THE SET
CAN OPERATE)
If the set arrives with the intake manifold disassembled,
make the connection using a pipe union or counter flange.
Connect the set's intake (“a”) and delivery (“b”) lines to
the system. The unit is supplied with threaded flanges or
flanged connections and with closing caps/flanges for the
manifold side not used for the connection. The dimension
of the connection pipes must be equal to or greater than
the set's intake and delivery manifolds; they must be as
short and straight as possible, and with a path that always
ascends towards the pumps (intake), using as few elbows
as possible, avoiding minimum number of elbows,
avoiding goosenecks that could cause siphons or air
pockets. Please note that in sets with 1 pump, the
manifold is not present and the connection is made
