5. TRANSPORTATION AND HANDLING
The product is packed to maintain the content intact.
During transportation avoid to stack excessive wei-
ghts. Ensure that during the transportation the
packed cannot move.
The transport vehicles must comply, for the weight
and dimensions, with the chosen product (see para-
graph 13.1 dimensions and weights).
5.1 Handling
Handle with care, the packages must not receive
impacts.
Raise the pump-motor unit slowly (fig.1), 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 refer to the annex
"Dimensions" (paragraph 13.1 Annexes).
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
Inspect the device in order to check any
damages which may have occurred during
transportation.
Package material, once removed, must be discar-
ded/recycled according to local laws of the destina-
tion country.
Raise the pump-motor unit slowly (see paragraph 5.1
fig.1), making sure it does not move from side to side
in an uncontrolled way, to avoid the risk of imbalance
and tipping up.
6.4. Installation
These pumps must be installed with the rotor axis
horizontal and feet downwards.
Place the pump as close as possible to the suction
source (with consideration given to the NPSH value).
Provide space around the pump for motor ventilation,
to allow for checking of shaft rotation, for filling and
draining the pump and to allow for collection of the
liquid to be removed.
6.4.1. Foundation
The smaller units are mounted on a
single-piece,
channel-steel baseplate
with a high degree of tor-
sional strength.
Whith this type of construction a foundation is not
indispensable, in the case of units of limited weight
and when light loads are expected through pipelines.
However, a raised foundation will facilitate draining of
pump casing and will provide extra height for safety
