7 Shut-down/disposal
All work must be carried out with the greatest care.
Proper protective clothing must be worn.
When carrying out work in basins and/or containers,
the respective local protection measures must be
observed in all cases. A second person must be present
for safety reasons.
Only hoisting gear that is in a technically perfect condi-
tion and load-carrying equipment that has been offi-
cially approved may be used for lowering and raising
the product.
Risk of fatal injury due to malfunctions!
Load-carrying equipment and hoisting gear must
be in a perfect technical condition. Work may
only commence if the hoisting gear has been
checked and found to be in perfect working
order. If it is not inspected, danger to personnel
may result!

7.1 Temporary shutdown

For this type of shutdown, the product remains
installed and is not cut off from the electricity supply.
For temporary shutdown, the product must remain
completely submerged so that it is protected from frost
and ice. Ensure that the temperature of the pumped
liquid and in the operating area does not fall below
+3 °C.
This ensures that the product will be ready for opera-
tion at all times. 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
operating and usage conditions. Never run the
machine dry! This can result in irreparable dam-
age!
7.2 Final shutdown for maintenance work or stor-
age
The system must be switched off and the product
must be disconnected from the mains by an electrician
and secured against being switched on again without
permission. Units with plugs must be unplugged (do
not pull the cable). Work on removing the product,
maintenance and storage can then commence.
Beware of poisonous substances!
Products that pump fluids which are hazardous
to health must always be decontaminated before
undertaking any other work! There is otherwise
a risk of fatal injury! Wear the necessary protec-
tive clothing for this work!

Beware of burns!
The housing parts can heat up to well above
104 °F (40 °C). There is a danger of burns! After
switching off, let the product cool down to
ambient temperature.
7.2.1 Removal
Products in portable wet installations can be lifted out
of the pit after being disconnected from the mains
power supply and emptying the discharge pipe. You
may have to disconnect the hose first. The use of
appropriate hoisting gear may also be necessary here.
The operating area must be emptied for stationary wet
installation. The unit must then be disconnected from
the discharge pipe and lifted out of the shaft with
hoisting gear. Make sure the power supply cable is not
damaged while doing this!
7.2.2 Return delivery/storage
For shipping, the parts must be packed and sealed in
sufficiently large, non-tearing plastic sacks to prevent
leakages. Shipping must be carried out by carriers who
have been briefed accordingly.
In this regard, please also refer to the chapter
"Transport and storage".
7.3 Starting up again
Clean the product of dust and oil deposits before
starting up again. Then carry out all the maintenance
tasks as described in the chapter entitled "Mainte-
nance".
Once this work has been completed, the product can
be installed and connected to the electricity supply by
an electrician. This work must be carried out in accor-
dance with the "Installation" chapter.
The product must be switched on as described in the
"Start-up" chapter.
The product may only be restarted if it is in per-
fect condition and ready for operation.
