5.4. Start-Up

The „Start-up" chapter contains all the important instruc-
tions for the operating personnel for starting up and oper-
ating the machine safely.
The following specifications must be adhered to and
checked:
• Type of installation
• Operating mode
• Minimum water coverage / max. submersion
If the machine has not been operated for some time,
check these specifications again and rectify any faults
you find!
The operation and maintenance handbook must al-
ways be kept either by the machine or in a place spe-
cially reserved for it where it is accessible for operat-
ing personnel at all times.
In order to prevent damage or serious injury during start-
up of the machine, the following points must be observed:
• The machine may only be started up by qualified
personnel. The safety advice must be followed at all
times.
44 | EngliSH
• Every person working on the machine must have re-
ceived, read and understood this operating and main-
tenance manual. This must also be confirmed with a
signature in the machine operator list.
• Activate all safety devices and emergency stop ele-
ments before start-up.
• Electrical and mechanical settings may only be made
by specialists.
• This machine may only be used under the working
conditions specified in this handbook.

5.5. Preparatory measures

The machine has been designed and constructed using
the very latest technology. Under normal working condi-
tions it will operate reliably and for long periods. The one
condition for this is that all instructions and advice are ob-
served.
Minor oil leakage in the mechanical shaft seal on delivery
is no cause for concern. However, it must be removed
prior to submersion in the pumped liquid.
Please check the following:
• Cable guidance – no loops, slightly taut
• Check the temperature and submersion depth of the
pumped liquid – see machine data sheet
• 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
• The pump sump must be cleaned for wet installation
• Clean the discharge and intake side pipe system and
open all sliders
• The pump housing must be flooded, i.e. it should be
completely full of fluid, with no air in it at all. Bleeding
can take place using a suitable bleeding device in the
system, or, if available, with bleeder screws on the
discharge port.
• Check that all accessories, the pipe system and sus-
pension unit are properly fitted
• Check all level control and dry-run protection systems
An insulation test and filling level check must be car-
ried out prior to start-up.

5.6. Electrical system

Observe the relevant local and national regulations when
laying out and selecting the electric lines as well as when
connecting the motor. The motor must be protected by
a motor protection switch. Have the motor connected in
accordance with the „Wiring connection" data sheet. Pay
attention to the direction of rotation. If the direction of ro-
tation is incorrect, the machine will not perform as speci-
fied, and under certain circumstances, can become dam-
aged. In accordance with the machine data sheet, check
the operating voltage and make certain that the current
consumption remains uniform during all phases. Make
sure that all temperature sensors and monitoring devices,
such as the sealing chamber monitor, are connected and
that their function is tested. For details on this, see the
wiring diagram.
Beware of electrical current!
Incorrectly performed electrical work can result in
fatal injury. This work may only be carried out by a
qualified electrician.
