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.
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
The pumps must be installed with the rotor axis in the
horizontal position and with the feet under the pump.
Place the pump as close as possible to the suction
source.
Provide space around the pump for motor ventilation,
to allow for checking of shaft rotation.
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 pipe diameters must be the same as the pump
connection diameters.
6.4.2. Suction pipe
The suction pipe must be perfectly airtight and be led
upwards in order to avoid air pockets.
6.4.3. Delivery pipe
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.
If the terminal box is provided with an inlet gland, use
a flexible power supply cord of the H07 RN-Ftype with
section of cable not less than (par. 12.3 TAB 1).
If the terminal box is provided with an inlet bushing,
connect the power supply cord through a conduit.
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 IM, are supplied with a capacitor
connected to the terminals and (for 220-240 V - 50 Hz)
with an incorporated thermal protector.
7. STARTUP AND OPERATION
7.1. Preliminary checks before start-up of the
pump
Do not start-up the device in case of damaged parts.
7.2. First starting
OFF
ATTENTION: never run the pump dry.
Start the pump after filling it with liquid thro-ugh the
delivery port, before connecting the pipe.
Before starting, check that the shaft turns by hand. For
this purpose use the screwdriver notch on the shaft
end on the ventilation side.
With three-phase motors check that the direction
of rotation is in the anticlockwise direction as seen
from the pump casing, clockwise if seen from the motor
fan; otherwise disconnect electrical power and reverse
