5.4 Preparatory work
The machine was designed and assembled in accordance with the latest technical standards so that it will work
reliably for a long time under normal operating conditions. This requires you to heed all requirements and notes.
Small oil leaks at the floating-ring type shaft seal following delivery are uncritical, but they must be removed before
lowering or submersion into the pumping medium.
Please check the following points:
• Cable routing – no loops, slightly tautened
• Check temperature of the pumping medium and submersion depth – see machine data sheet
• If a hose is used on the discharge side, this must be rinsed using clear water before use to prevent any
deposits leading to blockages.
• The discharge pipe system must be cleaned and all gate valves opened.
• The pump housing must be flooded i.e. it must be completely filled with the medium and not contain any air
whatsoever. Venting can be carried out using suitable venting devices in the system or, if available, through
venting screws on the discharge muff.
• control unit Check the accessories and pipe system for a tight and correct fit
• Check any level controls and/or dry-run protection
5.5 Electric system
The appropriate local and VDE regulations must be heeded for the routing and selection of electric cables and
connection of the motor. The motor must be protected by a motor protection switch. Have the motor connected
in accordance with the circuit diagram in the control unit installation and operating instructions. Watch out for the
correct direction of rotation. If the direction of rotation is not correct, the machine will not produce the given output
and may become damaged under unfavourable circumstances.
Risk caused by electric current! There is a danger to life if current is not handled properly. All pumps with
free cable ends must be connected by a qualified electrician.
An expert check before initial operation must guarantee that the electrical protective measures required
are in place. Earthing, neutral connection, isolating transformer, residual current- or voltage-operated
protective switches must comply with the regulations issued by the electricity board responsible.
The voltage specified in the technical data must correspond to the mains voltage on site.
Make sure that the electrical plug-type connectors are in the flood-protected area or are protected from
humidity. Mains supply cables and plugs must be checked for damage before use.
The end of the connection cable must not be submersed in the water since otherwise water can get into
the motor connection chamber.
Electrical connections must be made in accordance with the regulations of the local electricity board or VDE.
The supply voltage and frequency can be found on the type plates of the pump and the control unit. The voltage
tolerance must be within a range of +6% to -10% of the mains voltage. Care must be taken that the data specified
on the type plates correspond with the power supply available. The lifting stations do not require any further motor
protection.
The pump motors have a thermal switch installed in the motor windings which switches the pump off in the event
of the motor overheating or being subjected to excessive load. No further motor protection is required.
