English
Pay attention to the direction of rotation. If the direction of rota-
tion is incorrect, the unit will not perform as specified and may be
damaged.
Make sure all monitoring devices are connected and have been
tested.
ELECTRICAL hazard!
Electrical current can cause fatal injuries if not
handled correctly! All products with free cable
ends (i.e. without plugs) must be connected by a
qualified electrician.

Rotation direction check

The product is checked and adjusted in the factory to ensure that
the direction of rotation is correct. The connection must be made
according to the wiring code information.
A test run must be performed under general operat-
ing conditions.
6.2.1. Checking the rotation direction
The rotation direction must be checked with a rotating field tester
by a local electrician. For the correct rotation direction, a clockwise
rotating field must be available.
The product is not approved for operation with a
counter-clockwise rotating field.
6.2.2. If the direction of rotation is not correct
When using Salmson switching devices
Salmson switching devices are designed so that the connected
products are driven in the right direction. If the rotation direction
is wrong, 2 phases/leads of the mains supply to the switching
device must be replaced.
With switching devices provided by the customer:
If the rotation direction is wrong, with direct start motors, 2
phases must be swapped. In the case of star-delta start-up mo-
tors, the connections of two windings must be swapped, e.g. U1
with V1
and U2 with V2.
6.3.

Level controller

For correct adjustment, please see the installation and operation
manual for the level control device.
Note the following information:
• When using float switches, ensure that they can move
freely in the operating area.
• Make sure the cables are correctly laid.
• The water level must not fall below the minimum.
• The maximum starts per hour may not be exceeded.
6.4.

operation in explosion hazard areas

The operator is responsible for defining the explosion hazard area.
Only products with ex-approval may be used within an explosion
hazard area.
Products that are ex-approved are labeled on the type plate
as follows:
• ATEX symbol
• Ex-classification, e.g. II 2G EEx d IIB T4
• Ex-certification number, e.g. ATEX1038X
RISk of fatal injury due to explosion!
Products without ex-labeling may not be used in
explosion hazard areas! There is a risk of fatal in-
jury due to explosion! Observe the following when
using the pump in explosion hazard areas:
• The pump and attached accessories (incl. switching
device/plugs) must be approved for use in explosion
hazard areas!
• The power supply cable must be connected outside
the explosion hazard area, or inside a housing with
ignition protection conforming to DIN EN 60079-0!
• Switching devices must be installed outside the
explosion hazard area, or inside a housing with igni-
tion protection conforming to DIN EN 60079-0!
To keep dry motors sufficiently cooled when they
are not submerged, they must be flooded completely
before being switched back on!
6.5.

Start-up

Minor oil leakage in the mechanical shaft seal on delivery is no
cause for concern. However, it must be removed prior to submer-
sion in the pumped liquid.
keep out of the work area of the unit. no persons
are allowed in the work area during start-up or
operation.
Before switching on for the first time, the installation must be
checked as described in the "Installation" section and an isola-
tion check must be carried out according to the "Maintenance"
section.
BEWARE of serious injuries!
In portable installations, the unit can fall over when
it is switched on or during operation. Make sure
that the unit is positioned on a firm foundation and
that the pump pedestal is mounted correctly.
If the unit falls over, it must be switched off before setting it up
again.
For versions with plugs, the plug must have the correct IP protec-
tion class.
6.5.1. Before switching on
Check the following:
• Cable guidance – no loops, slightly taut
• Check the temperature of the pumped liquid and the sub-
mersion depth – see technical data
• If a hose is used on the discharge side, it should be flushed
out with clean water before use to prevent any sediment
causing blockages
• Clean coarse deposits from the pump sump
• Clean the pipe systems on the discharge and intake sides
• Open all valves on the discharge and intake sides
