4.5. Individual protection devices
During installation, starting and maintenance it is
suggested to the authorized operators to consider
the use of individual protection devices suitable for
described activities.
During ordinary and extraordinary maintenance
interventions, safety gloves are required.

HAND PROTECTION
(gloves for protection against chemical,
thermal and mechanical risks).
5. TRANSPORTATION AND HANDLING
The product is packed to maintain the content intact.
During transportation avoid to stack excessive weights.
Ensure that during the transportation the box cannot
move.
It is not necessary to use any special vehicle to
transport the packaged device.
The transport vehicles must comply, for the weight and
dimensions, with the chosen product (see technical
catalogue dimensions and weights).
5.1. Handling
Handle with care, the packages must not receive
impacts.
Avoid to impact onto the package materials that could
damage the pump.
If the weight exceeds 25 Kg the package must be
handled by two person at the same time.
6. INSTALLATION
6.1. Dimensions
For the dimensions of the device (see technical
catalogue).
6.2. Ambient requirements and installation site
dimensions
The customer has to prepare the installation site in
order to guarantee the right installation and in order to
fulfill the device requirements (electrical supply, etc...).
The place where the device will be installed must fulfill
the requirements in the paragraph 3.2.
It's Absolutely forbidden to install the machine in an
environment with potentially explosive atmosphere.
6.3. Unpacking
i
Inspect the device in order to check any
damages which may have occurred during
transportation.
Package material, once removed, must be discarded/
recycled according to local laws of the destination
country.
6.4. Installation
Minimum and maximum immersion depth within the
marks on the fig. 12.3.
The pump must be installed vertically, with the pump
casing submerged in the liquid handled and with the
motor in a well ventilated location, protected from the
weather.
The motor is not submersible.
Make sure all necessary precautionary
measures are taken to avoid minor or serious
accidents which may be caused by toxic
exhalation at the site of installation.
Provide clearance around the unit for motor ventilation,
for easier inspection and maintenance.
6.4.1. Pipes
Ensure the insides of pipes are clean and unobstructed
before connection.
ATTENTION: The pipes connected to the pump
should be secured to rest clamps so that they
do not transmit stress, strain or vibrations to the
pump.
The inside diameter of the pipe-work depends on the
desired flow.
The pipe diameters must never be smaller than the
pump connection ports.
6.4.2. Delivery pipe
Fit a gate valve in the delivery pipe to adjust delivery,
head, and absorbed power.
Install a pressure gauge.
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
name-plate data and connect the supply conductors
to the terminals in accordance with the appropriate
diagram inside the terminal box cover.
ATTENTION: never allow washers or other
metal parts to fall into the internal cable
opening between the terminal box and
stator. If this occurs, dismantle the motor to
recover the object which has fallen inside.
Place the power supply cable and all electrical
components above the top grade level of the liquid.
If the terminal box is provided with an inlet gland, use
a flexible power supply cord of the H07 RN-F type with
section of cable not less than (par. 12.2 TAB 1).
If the terminal box is provided with an inlet bushing,
connect the power supply cord through a conduit.
For use in swimming pools (not when persons are in
the pool), garden ponds and similar places, a residual
current device with IΔN not exceeding 30 mA must be
installed in the supply circuit.
Install a device for disconnection from the mains
(switch) with a contact separation of at least 3 mm in
all poles.
With a three-phase motor install an overload protection
device with curve D appropriate for the rated current
of the pump.
Single-phase B-VTM, are supplied with a capacitor
connected to the terminals and (for 220-240 V - 50 Hz)
with an incorporated thermal protector.
