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 12.1 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 refer to the annex
"Dimensions" (paragraph 12.1 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...).
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.
6.4. Installation
The internal diameter of the delivery pipe must never
be smaller than the diameter of the pump connection
port:

;
ATTENTION: The pump must be lifted and
transported using the handle fitted for this purpose
and not pulled by the electrical power cable.
Place the pump, with vertical axis, at the bottom of
the pit or at the site of installation.
6.5. Stationary installation
6.5.1. Stationary
installation
with
vertical
magnetic float switch
Installation fit a check valve against back flow in the
delivery pipe ball valve (swing valve for GXR).
Provide for the possibility of removing the pump
without having to drain the entire system (if
necessary, fit a gate valve and a union coupling).
With the pump in the resting position secure the
delivery pipe to a rest, suitable for its length and
weight.
If slime deposits are expected to form at the bottom
of the installation pit, a support must be provided to
keep the pump raised.
6.6. Transportable installation
To avoid early deterioration of the pump when used in
stagnant water or in rivers, mount on a flat surface rai-
sed from the ground so that sand or grit is not lifted.
When a plastic delivery pipe or flexible hose is used,
a rope is required for lowering, securing and lifting
the pump.
A
safety rope or chain
of non-perishable material
should always be used to secure the pump.
Never use the electric power cable to
suspend the pump.
In order to avoid the risk of mechanical or
electrical injury all portable pumps should be
securely isolated from electrical power supply
prior to their relocation.
Attach the power supply cable to the delivery pipe or
to the safety rope with cable clamps. The power
cable should not be taut: allow for a certain degree of
slackness to avoid the risk of strain caused by
expansion of the pipe during operation.
If you think the sump may dry, drill a 3 mm hole in the
delivery pipe before the non-return valve, to allow the
air around the rotor to exit par. 12.2. fig. 1.
