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
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 "General
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.

7.3 Restarting after an extended period of storage

Before restarting the machine, clean it of dust and oil
deposits. 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
must remain completely
(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

In order to prevent damage or serious injury while rectifying
machine faults, the following points must be observed:

Only attempt to rectify a fault if you have
qualified personnel. This means each job
must be carried out by trained specialist
personnel, for example electrical work must
be performed by a trained electrician.

Always secure the machine against an
accidental restart by disconnecting it from the
electric system. Take appropriate safety
precautions.

Independent work on the machine is at one's
own risk and releases the manufacturer from
any warranty obligation.
