4. Transport and storage
4.1. Delivery
On delivery, check immediately that the ship-
ment is complete and undamaged. If any parts
are damaged or missing, the transport company
or the manufacturer must be notified on the day
of delivery. Claims made after this date cannot be
recognised. Damage to parts must be noted on
the delivery or freight documentation.
4.2. Transport
Only the appropriate and approved lifting gear,
transportation and hoisting gear may be used.
These must have sufficient load-bearing capacity
to ensure that the pump can be transported safe-
ly. If chains are used they must be secured against
slipping.
The personnel must be qualified for the tasks and
must follow all applicable national safety regula-
tions during the work.
The pump is delivered by the manufacturer or
shipping agency in suitable packaging. This nor-
mally precludes the possibility of damage occur-
ring during transport and storage. The packaging
should be stored in a safe place for reuse if the
product is frequently used at different locations.
4.3. Storage
Newly delivered submersible pumps are prepared
in such a way that they can be stored for at least
1 year. The pump should be cleaned thoroughly
before it is put into temporary storage.
The following should be taken into consideration
for storage:
• Place the pump on a firm surface and secure it
against slipping and falling over. Submersible
pumps can be stored vertically or horizontally.
If pumps are stored horizontally in more than 9
layers, ensure that they do not bend.
Otherwise, impermissible bending tensions can
arise in the hydraulics and the pump may be
damaged. Support the hydraulics accordingly.
DANGER due to falling over!
Never set the unit down unsecured. If the
pump falls over, this may lead to injuries!
• Submersible pumps can be stored at tempera-
tures down to -15 °C. The store room must be
dry. We recommend a frost-protected room for
storage with a temperature between 5 °C and
25 °C.
Installation and operating instructions Wilo-Sub TWU 3/High Speed
• The submersible pump is not allowed to be stored
in rooms in which welding work is carried out, be-
cause the resulting gases or radiation can damage
the elastomer components and coating.
• The pump's suction and pressure connections
and the external frequency converter should be
permanently sealed to prevent contamination.
• All power supply cables must be protected
against kinking, damage and moisture ingress.
ELECTRICAL hazard!
Damaged power supply cables can cause fatal
injury! Defective cables must be replaced by
a qualified electrician immediately.
BEWARE of moisture!
Moisture penetrating the cable will damage
both the pump and the cable. For this reason,
never immerse the cable end in the fluid or
any other liquid.
• The submersible pump and the external fre-
quency converter must be protected from direct
sunlight, heat, dust, and frost.
• If the submersible pump and the external fre-
quency converter have been stored for a long pe-
riod of time, they should be cleaned of impurities
such as dust and oil residue before commission-
ing. Check that the impellers move freely.
However, note that the elastomer components
and coatings are subject to natural embrittle-
ment. In case of storage for longer than 6 months,
we recommend checking them and renewing
them if necessary. Please contact the manufac-
turer about this.

4.4. Return delivery

Pumps that are returned to the factory must be
properly packaged. This means that impurities
have been removed from the pump and that it has
been decontaminated if used with fluids that are
hazardous to health.
For shipping, the parts must be packed in tear-
proof plastic bags of sufficient size in such
a manner that they are tightly sealed and leak-
proof. Furthermore, the packaging must protect
the pump from damage during transportation.
If you have any questions, please contact the
manufacturer!
5. Installation
In order to prevent damage to the product or seri-
ous injury during installation, the following points
must be observed:
• Installation work – assembly and installation of
the submersible pump – may only be carried out
by qualified persons. The safety instructions must
be followed at all times.
• The submersible pump must be inspected for
transport damage before any installation work is
carried out.
