If you are using level controllers, make sure that the minimum
water coverage is present. Air pockets must not be allowed to
enter the hydraulic housing or the pipeline system, and they must
be removed with suitable bleeding equipment or by inclining the
product slightly (with a portable installation). Protect the product
from frost.
5.2. Types of installation
• Vertical stationary wet installation with suspension device
• Vertical portable wet installation with pump pedestal
5.3. The operating area
The operating area must be clean, free of coarse solids, dry, frost-
free and, if necessary, decontaminated. It must also be suitable for
the respective product. When working in shafts, a second person
must be present for safety reasons. If there is risk of poisonous or
asphyxiating gases forming, the necessary precautions must be
taken!
When installing in shafts, the size of the shaft and the cool-down
time of the motor must be determined by the system planner,
depending on the ambient conditions prevailing during operation.
To keep dry motors sufficiently cooled when they
are not submerged, they must be flooded completely
before being switched back on!
It must be ensured that hoisting gear can be fitted without any
trouble, since this is required for assembly and removal of the
product. It must be possible to reach the product safely in its
operating and storage locations using the hoisting gear. The ma-
chine must be positioned on a firm foundation. For transporting
the product, the load-carrying equipment must be secured to the
lifting eyelets provided.
Electric power cables must be laid out in such a way that safe op-
eration and trouble-free assembly/dismantling are possible at all
times. The product must never be carried or dragged by the power
supply cable. When using switching devices, they must have the
appropriate protection class. Switching devices must always be
mounted in such a way that they are protected from flooding.
When used in an explosive atmosphere, it must be ensured that
the product and all accessories are approved for this purpose.
The structural components and foundations must be of sufficient
stability in order to allow the product to be anchored securely
and functionally. The operator or the supplier is responsible for
the provision of the foundations and their suitability in terms of
dimensions, stability and strength.
Never let the machine run dry. The water level must never fall
below the minimum. Therefore, we recommend installing a level
control system or a dry-run protection system where there are
great variations in the level.
Use guide and deflector plates for the pumped liquid intake. If the
water jet reaches the surface of the water, air will be introduced
into the pumped liquid. This will lead to unfavorable current and
pumping conditions for the unit. As a result of cavitation, the
product will not run smoothly and will be subjected to increased
wear.
5.4. Installation
DAnGER of falling!
When installing the product and its accessories,
work is sometimes performed directly at the edge
of the basin or shaft. Carelessness or wearing
inappropriate clothing could result in a fall. There
is a risk of fatal injury! Take all necessary safety
precautions to prevent this.
The following information must be observed when installing
the product:
• This work must be carried out by a qualified person and
electrical work must be carried out by an electrician.
• Lift the unit by the handle or lifting eyelets, never by the
power supply cable. When using chains, they must be con-
nected with a shackle to the lifting eyelets or the carrying
handle. Fastening devices must be technically approved.
• Check that the available planning documentation (instal-
lation plans, layout of the operating area, intake ratios) is
complete and correct.
NOTE
• If the motor housing is to be taken out of the pumped
liquid during operation, the operating mode for
emerged operation should be followed.
• Never let the machine run dry. We recommend that
dry-run protection be installed. If fluid levels deviate
dramatically, a dry-run protection must be installed.
• Check whether the cable is long enough for its
cross-section and its installation type. (For more in-
formation, consult the catalog, the planning manuals
or Salmson customer service).
• Observe all regulations, rules and legal requirements for
working with and underneath heavy suspended loads.
• Wear appropriate protective clothing/equipment.
• A second person must always be present when working in
shafts. If there is risk of poisonous or asphyxiating gases
forming, the necessary precautions must be taken!
• Please also observe the applicable national accident pre-
vention regulations and trade association safety provi-
sions.
• Inspect the coating before installation. If defects are
found, these must be rectified before installation.
5.4.1. Stationary wet installation
A suspension unit must be installed for wet installation. This must
be ordered separately from the manufacturer. The pipeline system
on the discharge side is connected to this.
The connected pipe system must be self-support-
ing, i.e. it may not be supported by the suspension
device.
The operating area must be laid out so that the suspension device
can be installed and operated without difficulty.
