WILO SE 10/2022 V05 DIN A4
English SHUTDOWN/DISPOSAL
During operation, all gate valves in the suction and discharge
pipe must be completely open.
If the slide valves on the suction and discharge sides are
closed during operation, the fluid in the hydraulics housing
is heated up by the pumping movement. This heating
creates strong pressure in the hydraulics housing. The
pressure can result in the hydraulics exploding! Before
switching on the hydraulics, ensure that all the slide valves
are open and open any closed slide valves if necessary.

Shutdown/disposal
NOTICE
Also note all the information regarding
shutdown/disposal in the operating and
maintenance manual for the motor!
• All work must be carried out with the greatest care.
• Proper protective clothing must be worn.
• When carrying out work in basins and/or tanks, the
respective local protection measures must be observed.
A second person must be present for safety reasons.
• Lifting equipment in perfect technical condition and
officially approved lifting gear must be used for lifting
and lowering the hydraulics.
DANGER! Risk of fatal injury due to malfunc-
tion!
Lifting gear and lifting equipment must be in
perfect technical condition. Work may only
commence if the lifting equipment has been
checked and is found to be in perfect working
order. If it is not inspected, there is a risk of
fatal injury!
7.1.
Shutdown
1. Switch the electronic control for the unit to manual
mode.
2. Close gate valve on the suction side.
3.
Manually activate the unit to pump the remaining fluid
into the discharge pipeline.
4. Switch off the motor and secure it against being
switched on again by unauthorised persons.
5. Close gate valve on the discharge side.
6. Work on removal, maintenance and storage can now
commence.
7.2.
Removal
DANGER due to toxic substances!
Hydraulics 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
protective clothing!
CAUTION! Risk of burns!
The housing parts can heat up to well above
40 °C. There is a risk of burns!
• Never touch parts of the housing with your
bare hands.
• After switching them off, let the hydraulics
cool down to ambient temperature.
• Wear heat-resistant protective gloves.
NOTICE
Note that the residual fluid in the hydraulics
housing will escape during removal. Suitable
collector tanks should be positioned to collect
all of the escaping fluid!
1.
Have a qualified electrician disconnect the motor from
the mains.
2.
Drain the residual fluid through the drainage screw on
the hydraulics (Fig. 1, Item 8).
Caution: Collect the fluid in a suitable tank and dispose of
it properly.
3. To remove the hydraulics, you have to loosen the
screwed connections on the suction and discharge ports
and the floor fixation on the hydraulics housing and on
the support.
4. Attach the lifting equipment to the corresponding
attachment points. For horizontal installation,
to do this,
you must first attach
the enclosed transport shackle
(Fig. 2, Item 1)
to the discharge port
. The hydraulics can
then be removed from the operating space.
5. The operating space must be cleaned thoroughly after
the hydraulics is removed, and any drips must be wiped
up.
7.3.
Return delivery/storage
For shipping, the parts must be packed in tear-proof plastic
bags of sufficient size in such a manner that they are tightly
sealed and leak-proof.
For return delivery and storage, please also refer to the
“Transport and storage” section!
