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 tempo-
rary shutdown, the machine must remain completely sub-
merged 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 opera-
tion. During longer shutdown periods, carry out a regular
(monthly to quarterly) function run for a period of 5 minu-
tes.
Caution!
Only carry out a function run under the proper con-
ditions of operation and use. 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 fol-
lowing information concerning storage:
Beware of hot parts!
When removing the machine, be careful of the tem-
perature 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 pre-
ventive measure against brittleness in elastomer
parts and the propeller and casing coating.
• When storing the machine in a garage please remem-
ber: Radiation and gases which occur during electric
welding destroy the elastomers of the seals.
• During lengthy periods of storage, regularly (for ex-
ample every six months) turn the impeller or propeller
by hand. This prevents indentations in the bearings
and stops the rotor from rusting up.

7.3. Restarting after an extended period of storage

Before restarting the machine, clean it of dust and oil de-
posits. Then carry out the necessary maintenance actions
(see "Maintenance"). Check that the mechanical shaft
seal is in good order and working properly. Once this work
has been completed, the machine can be installed (see
"Installation") and connected to the electricity supply by
a specialist. See "Start-up" for instructions on restarting.
Only restart the machine if it is in perfect condition and
ready for operation.

8. Troubleshooting

The following points must be taken into account to avoid
personal and material damage when troubleshooting
machine failures:
• Correct a failure only if you have qualified staff, i.e.
the individual work must be carried out by trained
specialist personnel, e.g. electrical work must be
carried out by a qualified electrician.
• Always prevent the machine from unintentional
restart by disconnection it from the power supply.
Take appropriate precautionary measures.
• Ensure the safety shut-down of the machinery by a
second person at all times.
• Safeguard mobile machinery parts to prevent inju-
ries.
• Unauthorized changes on the machinery are at
own risk and discharge the manufacturer from any
liability!
