Sound Pressure; Transport And Storage - Wilo EMU KS Serie Notice De Montage Et De Mise En Service

• It is strictly prohibited to pump explosive or highly
flammable liquids in pure form!
Danger - explosive liquids!
It is strictly prohibited to pump explosive liquids
(gasoline, kerosene, etc.). The products are not
designed for these liquids!

2.12 Sound pressure

Depending on the size and capacity (kW), the prod-
ucts produce a sound pressure of approximately 70 dB
(A) to 110 dB (A).
The actual sound pressure, however, depends on sev-
eral factors. These include, for example, the installation
depth, configuration, fastening of accessories and
pipeline, operating point, immersion depth, etc.
Once the product has been installed, we recommend
that the operator make an additional measurement
under all operating conditions.
Caution: Wear ear protectors!
In terms of the applicable laws and regulations,
ear protection must be worn if the sound pres-
sure is greater than 85 dB (A)! The operator is
responsible for ensuring compliance with these
regulations!

3 Transport and storage

3.1 Delivery
Upon receipt of the delivery, it is immediately checked
for damage and completeness. If any parts are dam-
aged or missing, the transport company or the manu-
facturer must be informed on the day of delivery.
Claims made after this date cannot be recognized.
Damage to parts must be noted on the delivery or
freight documentation.
3.2 Transport
Only the appropriate and approved fastening devices,
transportation means and lifting gear may be used.
These must have sufficient load-bearing capacity to
ensure that the product can be transported safety. If
chains are used they must be secured against slipping.
The personnel must be qualified for the tasks and must
follow all national safety regulations in effect during the
work.
The product is delivered by the manufacturer / ship-
ping agency in suitable packaging. This normally pre-
cludes the possibility of damage occurring during
transport and storage. The packaging should be stored
in a safe place for reuse if the product is frequently
used at different locations.
Beware of frost!
If drinking water is used as a coolant/lubricant,
the product must be protected against frost dur-
ing transport. If this is not possible, the product
must be drained and dried out!

3.3 Storage
Newly supplied products are prepared so that they can
be stored for at least 1 year. The product should be
cleaned thoroughly before it is put into temporary
storage!
The following should be taken into consideration for
storage:
• Place the product on a firm surface and secure it
against slipping and falling over. Wastewater and sew-
age submersible pumps are stored vertically.
Danger from falling over!
Never set down the product unsecured. If the
product falls over, injury can occur!
• Our products can be stored at temperatures 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.
Products that are filled with drinking water can
only be stored in frost-free rooms, at no less than
3 °C, for up to 4 weeks. If longer storage is
intended, the products should be emptied and
dried out beforehand.
• The product may not be stored in rooms where weld-
ing work is conducted as the resulting gases and radi-
ated heat can damage the elastomer parts and
coatings.
• Any suction or discharge ports should be closed tightly
before storage to prevent impurities.
• The current supply cables should be protected against
kinking, damage, and moisture.
Beware of electrical current!
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 damages both
the product and cable. Therefore, never immerse
cable ends in the pumped liquid or other liquids.
• The machine must be protected from direct sunlight,
heat, dust, and frost. Heat and frost can cause consid-
erable damage to propellers, rotors and coatings!
• The rotors or propellers must be rotated at regular
intervals. This prevents the bearing from locking, and
the film of lubricant on the mechanical shaft seal is
renewed. This also prevents the gear pinions (if pres-
ent on the product) from locking and also renews the
lubricating film on the gear pinions (preventing rust
film deposits).
Beware of sharp edges!
Sharp edges can form on rotors, propellers and
hydraulic openings. There is a risk of injuries!
Wear protective gloves.
• If the product has been stored for a long period of time
it should be cleaned of impurities such as dust and oil
deposits before start-up. Rotors and propellers should
