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.
Signal individual protection device
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.
Raise the pump-motor unit slowly (par. 12.3 g.7),
making sure it does not move from side to side in an
uncontrolled way, to avoid the risk of imbalance and
tipping up.
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
fulll the device requirements (electrical supply, etc...).
The place where the device will be installed must fulll
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
See installation examples, par. 12.3 g. 1 and 2.
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 rota-tion, for lling and
draining the pump and to allow for collection of the liquid
to be removed (especially for draining liquids which are
harmful or have to be removed at temperatures higher
than 60 °C).
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 (par. 12.3 g. 3).
Tighten the pipes or union coupling to the extent
sufcient to ensure a tight seal (par. 12.3 g. 6).
Excessive torque may cause damage to the pump.
When the pipe or union coupling is mounted, keep
the pump casing connection blocked with a second
wrench, making sure the connection is not deformed
by excessive tightening.
The pipe diameters must not be smaller than the pump
connections.
6.4.2. Suction pipe
If the suction pipe is longer than 10 m, use an internal
pipe diameter larger than the pump suction connection.
The suction pipe must be perfectly airtight and be led
upwards in order to avoid air pockets.
With a pump located above the water level (suction lift
operation, par. 12.3. g. 2) t a foot valve with strainer
which must always remain immersed.
If operating with exible hoses use a reinforced spiral
suction hose, in order to avoid the hose narrowing due
to suction vacuum.
With the liquid level on the suction side above the
pump (inow under positive suction head, par. 12.3.
g. 1) t an inlet gate valve.
For suction from a storage tank t an anti-backow
valve. Follow local specications if increasing network
pressure.
Install a strainer on the suction side of the pump to
prevent foreign particles from entering the pump.
6.4.3. Delivery pipe
Fit a gate valve in the delivery pipe to adjust delivery
and head.
Install a pressure gauge.
With a geodetic head at outlet over 15 m t a check
valve between the pump and the gate valve in order to
protect the pump from water hammering.
6.5. Electrical connection
OFF
Electrical connection must be carried out only
by a qualied 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.
