6.2.3 Ventilate the unit and piping
• Open all of the slide valves in the pressure pipe.
• Switch on the unit.
The air escapes through the corresponding air
vent valves. If no air vent valves have been in-
stalled, open the taps so that the air can escape!
7 Decommissioning/disposal
All work must be carried out with the greatest
care.
Proper protective clothing is to be worn.
When carrying out work in wells and/or tanks,
the respective local protection measures must be
observed in all cases. A second person must be
present for safety reasons.
Auxiliary lifting devices in perfect technical con-
dition and officially approved lifting gear must be
used for lifting and lowering the unit.
DANGER! Risk of fatal injury due to malfunc-
tion!
Lifting gear and lifting devices must be in a
perfect technical condition. Work may only
commence if the lifting device has been
checked and found to be in perfect working
order. If it is not inspected, there is a risk of
fatal injury!
7.1 Temporary decommissioning
For this type of deactivation, the unit remains
installed and is not cut off from the electricity
supply. In the event of temporary decommission-
ing, the unit must remain completely immersed so
that it is protected from frost and ice. Ensure that
the temperature in the operating space and of the
fluid does not fall below +3 °C.
The unit is thus ready for operation at any time.
For extended downtime, a regular (monthly
to quarterly) 5 minute function test should be
carried out.
CAUTION!
Only perform function runs under the proper
operating and usage conditions. Never run
the machine dry! Violating this can lead to
irreparable damage!
7.2 Decommissioning for maintenance work or
storage
• Switch off the system and secure it against being
switched on again by unauthorised persons.
• Get a qualified electrician disconnect the unit
from the mains.
• Close the slide valves in the pressure pipe down-
stream of the well cover.
You can then begin disassembly.

DECOMMISSIONING/DISPOSAL
DANGER due to toxic substances!
Units that pump liquids hazardous to health
must always be decontaminated before
undertaking any other work! Otherwise there
is a risk of fatal injury! Wear the necessary
protection clothing!
CAUTION! Risk of burns!
The housing parts can heat up to well
above 40 °C. There is a risk of burns! After
switching it off, let the unit cool down to
ambient temperature.
7.2.1 Removal
For more detailed descriptions on disassembling
the unit, see the installation and operating in-
structions of the unit/hydraulics.
In the case of horizontal installation, the water
tank/reservoir has to be drained completely.
Afterwards, the unit can be released from the
pressure pipe and disassembled.
To dismantle the motor, follow the assembly
steps in reverse order.
7.2.2 Return delivery/storage
For shipping, the parts must be packed in tear-
proof plastic bags of sufficient size in such a
