Use guide and deflector plates for the pumped liquid intake. If
the water jet reaches the surface of the water, air will be intro-
duced into the pumped liquid. This will lead to unfavorable cur-
rent and pumping conditions for the unit. As a result of
cavitation, the product does not run smoothly and is subjected
to increased wear.
5.4 Installation
Danger of falling!
When installing the product and its accesso-
ries, work is sometimes performed directly at
the edge of the basin or shaft. Carelessness
and/or wearing inappropriate clothing could
result in a fall. There is a risk of fatal injury!
Take all necessary safety precautions to pre-
vent this.
The following information must be observed when installing the
product:
- This work must be carried out by a qualified person and elec-
trical 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 (installation
plans, layout of the operating area, intake ratios) is complete
and correct.
If the motor housing is to be taken out of the pumped
liquid during operation, the operating mode for
emerged operation should be followed. If this operat-
ing mode is not specified, operation with an emerged
motor housing is strictly forbidden.
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 cross section of the cable used is
sufficient for the required cable length (see the cata-
log and planning documents or consult Salmson cus-
tomer service for more information).
- Please 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 danger of poisonous or asphyxiating gases
forming, the necessary countermeasures must be taken!
- Please also observe the applicable national accident preven-
tion regulations and trade association safety provisions.
- The coating is to be examined before installation. If defects
are found, these must be rectified before installation.

A suspension unit must be installed for wet installation. This
must be ordered separately from the manufacturer. The pipe-
line system on the discharge side is connected to this. The con-
nected pipe system must be self-supporting, i.e. it may not be
supported by the suspension unit. The operating area must be
laid out so that the suspension unit can be installed and oper-
ated without difficulty.
1 Install suspension unit in operating area and prepare the
product for operation on a suspension unit.
2 Check that the suspension unit is firmly fixed and functions
properly.
3 Have an electrician connect the product to the power supply
and check the direction of rotation in accordance with the
chapter entitled "Start-up".
4 Secure the product to the load-carrying equipment, lift and
lower slowly on to the guide pipes in the operating area. Hold
the electric power cables slightly taut when lowering. When
the product is connected to the suspension unit, make sure
that the electric power cables are secured adequately against
falling off and damage.
5 The correct operating position is reached automatically and
the discharge port is sealed by its own weight.
6 For new installation: Flood the operating area and bleed the
discharge pipe.
7 Start the product in accordance with the chapter entitled
"Start-up".
Beware of damaging threads!
Threads can be damaged by excessive
screwing and different flanges.
Therefore, please note:
Only use M16 thread bolts with a maximum
length of 12...16 mm.
The maximum
SVO 205) / 25 Nm (SCA/SVO 206).
Only use flanges confirming to DIN 2576 form
B (without sealing strip).
This requirement is fulfilled by the use of
Salmson accessories.

This installation type makes optional positioning in the operat-
ing area possible because the product is set down directly at
the place of use. A pedestal is integrated in the hydraulics for
this purpose. This ensures the minimum floor clearance and a
secure position on a firm foundation. For use on a soft founda-
tion, a hard base must be used to prevent the machine from
subsiding. A discharge hose is connected on the discharge
side.
