• All safety devices and emergency cut-outs must be con-
nected and checked to ensure that they work properly.
• Electrical and mechanical adjustments must be made by
specialist staff.
• The product is suitable for use under the specified operat-
ing conditions.
• The work area of the product is not a recreational area and
is to be kept free of people! No persons are allowed in the
work area during start-up or operation.

6.1.
Electrical system
Connect the product and the power supply cables installed as
described in the "Installation" section and in accordance with the
VDE guidelines and applicable national regulations.
The product must be properly protected and grounded.
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.
6.2.
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
Check the following points during level control:
• When using float switches, ensure that they can move
freely in the operating area!
• Check that the cable of the float switch is fixed correctly
on the pressure pipe or wall.
• The water level must not fall below the minimum!
• The maximum starts per hour may not be exceeded.
When using a separate level control device, please consult the
setting information in the installation and operation manual.
6.4.
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.
6.4.1. 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 sliders on the discharge and intake sides
LETHAL explosion hazard
If the shut-off valves on the intake and discharge
side are closed during operation, the fluid in the
hydraulic housing will be heated up by the pumping
movement. Considerable pressure is created in the
hydraulic housing by the heating. The pressure can
cause the unit to explode! Before switching on the
unit, ensure that all the valves are open.
• The hydraulic housing must be flooded, i.e. it should be
completely full of fluid, with no air in it at all. Bleeding can
be carried out using a suitable bleeding device in the sys-
tem, or, if available, with bleeder screws on the discharge
port.
