3. Receiving the product
3.1 Transporting the product
The individual components of the pump must be
packed carefully to prevent any damage to the
surface protection during transportation.
Warning
Make sure that the pump cannot roll or fall
over.
Warning
Before attempting to lift or otherwise
handle the individual components of the
pump, observe any local regulations that
set limits for the weight of the components
to be lifted manually by individuals, i.e.
handled without the use of lifting
equipment.
All lifting equipment must be rated for the purpose
and checked for damage before any attempts to lift
the components are made. The lifting equipment
rating must under no circumstances be exceeded.
3.2 Inspecting the product
On delivery, the pump and any accessories supplied
with it must be checked for transport damage. This
also applies when the equipment is delivered to the
installation site.
If the pump or any accessories have been damaged
during transportation, contact your local Grundfos
company before continuing to install the equipment.
Do not dismantle a damaged new component for
further inspection, unless instructed by your local
Grundfos company.
The packaging material must be disposed of
according to local regulations.
3.3 Storing the product
The pump must be stored in a dry location in which
the temperature is not subject to major fluctuations.
If the pump has been stored for more than one year,
the gearbox oil must be changed. The oil must be
changed even if the pump has never been in use.
This is necessary because of natural aging of
mineral oil lubricants.
4. Installing the product
During installation, the pump must only be lifted
when using the suspension point.
The lifting equipment supplied with the pump as well
as the wire used for lifting and lowering the pump
into the tank must not be used as universal lifting
equipment.
Never hang the pump by the supply cable.
Caution
Never let the pump run while hanging in
the lifting equipment.
4.1 Positioning
Correct positioning of the pump is essential to
ensure trouble-free operation and long life. The
following guidelines must be observed:
•
If more pumps are installed in the same tank,
they must not generate opposite flows.
•
The distance from the centre of the pump to the
tank bottom (H
) must be equal to the impeller
min
diameter. See fig. 1.
•
The distance from the top of the pump rack to the
liquid surface (H
ABOVE
following two requirements:
– For pumps with vortex shield, the distance
must at least be equal to the impeller diameter.
– For pumps without vortex shield, the distance
must at least be equal to 1.5 times the impeller
diameter. See fig. 1.
