English SHUTDOWN/DISPOSAL
6.6. Conduct during operation
CAUTION! Risk of burns!
The housing parts can heat up to well above
40 °C (104 °F). There is a risk of burns!
• Never touch parts of the housing with your
bare hands.
• After switching the pump off, let it cool down
to ambient temperature first.
• Wear heat-resistant protective gloves.
During pump operation, always follow the locally
applicable laws and regulations for work safety,
accident prevention and handling electrical
machinery. To help ensure safe working prac-
tice, the responsibilities of employees should be
clearly specified by the operator. All personnel
are responsible for ensuring that regulations are
observed.
During operation, all gate valves in the inlet line
and pressure 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.
6.7. Vibration measurement (Fig. 11)
WARNING! Rotating parts!
During operation, the coupling and the two
drive shafts rotate. Danger of serious injuries
to legs and arms. A vibration measurement
may only be carried out if the coupling guard
is firmly installed!
CAUTION! Risk of burns!
The housing parts can heat up to well above
40 °C (104 °F). There is a risk of burns! Wear
heat-resistant protective gloves.
Depending on the medium and the duty point,
vibrations may occur at the pump. These vibra-
tions act as forces and torques on the connection
ports and are dissipated into the foundation via
the floor fixation. Furthermore, unacceptable
vibrations promote faster wear of the pump bear-
ings, the mechanical seal and the coupling.
The vibration measurement must be carried out
at the duty point with the machine running.
1. Place the measuring point on the first measuring
point “M1”: top side of bearing housing (vertical
vibration)
2. Place the measuring point on the second meas-
uring point “M2”: laterally on the bearing housing
(horizontal vibration)
3. The measured value may not exceed
4.5 mm/s eff. (0.18 in/s). If the value is higher
than this, consult the Wilo customer service.
7. Shutdown/disposal
NOTICE
Also note all the information regarding
shutdown/disposal in the operating and main-
tenance manual for the motor and the coupling!
• All work must be carried out with the greatest
care.
• Proper protective clothing is to be worn.
• When working in enclosed spaces, the respective
local protection measures must be observed. A
second person must be present for safety
reasons.
• Only lifting equipment that is in a technically
perfect condition and lifting gear that has been
officially approved may be used for lowering and
raising the pump.
DANGER! Risk of fatal injury due to
malfunction!
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 pump to manual mode via the
electronic control.
2. Close gate valve on suction side.
3. Manually activate the pump to pump the remain-
ing quantity of fluid into the pressure pipe.
4. Switch off the system and secure it against being
switched on again by unauthorised persons.
5. Close gate valve on the pressure side.
6. Work on removal, maintenance and storage can
now commence.
7.2. Removal
DANGER due to toxic substances!
Pumps 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 (104 °F). There is a risk of burns!
• Never touch parts of the housing with your
bare hands.
• After switching the pump off, let it cool down
to ambient temperature first.
• 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!
