6.2 Maintenance intervals
Every six months:
Visual inspection of the power supply cable
Visual inspection of the cable holder and the cable bracing
Visual inspection of accessories, e.g. the suspension device and hoisting gears
6.3 Maintenance tasks
Visual check of power supply
The power supply line must be examined for bubbles, cracks, scratches, chafed areas and/or crushed sections. If
damage is found, the power cable must be exchanged immediately.
The cables may only be changed by the manufacturer or an authorized/certified service workshop. The
machine may not be used again until the damage has been adequately rectified.
Visual examination of the cable holders (carabiners) and the cable bracing
When the machine is used in basins or pits, the lifting cables/cable holders (carabiners) and the cable bracing are
subject to constant wear. Regular inspections are necessary in order to prevent the lifting cables/cable holders
(carabiners) and/or cable bracing from wearing out and to prevent the electricity cable from being damaged.
The lifting cables/cable holders (carabiners) and the cable bracing are to be immediately replaced if any
signs of wear appear.
Visual inspection of accessories
Inspect accessories such as suspension units and hoisting gear to check whether they are secured in a stable
manner. Loose and/or defective accessories should be repaired immediately or replaced.
7. Shutdown
7.1 Temporary shutdown
For this type of shutdown, the machine remains installed and is not cut off from the electricity supply. For
temporary shutdown, the machine must remain completely submerged so that it is protected from frost and ice.
Make sure the operating room and the pumped fluid cannot be covered by ice.
This ensures that the machine is always ready for operation. During longer shutdown periods, carry out a regular
(monthly to quarterly) function run for a period of 5 minutes.
Caution!
Only carry out a function run under the proper conditions
of operation and use (see “Product
Description”). Never run the machine dry. This can result in irreparable damage!
7.2 Final shutdown / storage
Switch off the system, disconnect the machine from the electricity supply and dismantle and store it. Note the
following information concerning storage:
Beware of hot parts!
When removing the machine, be careful of the temperature of the housing components. These can heat
up to well above 40°C. Let the machine cool down to ambient temperature before you touch it.
Clean the machine.
Store it in a clean, dry place, protect the machine against frost.
Place it down vertically onto a firm foundation and secure it against falling.
Seal the intake and discharge ports of pumps with suitable material (such as foil).
Support the electric connecting lead on the cable lead-in to help avoid a permanent deformation.
Protect the ends of the electric power cable from moisture.
Protect the machine from direct sunshine as a preventive measure against brittleness in elastomer
parts and the propeller and casing coating.
When storing the machine in a garage please remember: Radiation and gases which occur during
electric welding destroy the elastomers of the seals.
During lengthy periods of storage, regularly (for example every six months) turn the impeller or
propeller by hand. This prevents indentations in the bearings and stops the rotor from rusting up.
