6.5.2. Switching on/off
The standard motor is switched on and off using a
separate operating point (on/off switch, switch-
gear) provided by the customer.
See the information in the operating and main-
tenance manual for the motor.
6.6. Conduct during operation
BEWARE 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!
During operation of the hydraulics, always follow
the locally applicable laws and regulations for
work safety, accident prevention and handling
electrical machinery. To help ensure safe working
practice, 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 pres-
sure 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.
7. Decommissioning/disposal
NOTE
Also note all the information regarding decom-
missioning/disposal in the operating and main-
tenance manual for the motor!
• All work must be carried out with the greatest
care.
• Proper protective clothing is to 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 load-bearing equip-
ment must be used for lifting and lowering the
hydraulics.

DECOMMISSIONING/DISPOSAL
RISK of fatal injury due to malfunctions!
The lifting gear and lifting equipment must
be in a technically sound condition. Work
may only commence if the lifting equipment
has been checked and found to be in perfect
working order. If it is not inspected, fatal
injuries may result.
7.1. Decommissioning
1. Switch the electronic control for the unit to
manual mode.
2. Close gate valve on suction side.
3. Manually activate the unit to pump the remaining
quantity of 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 pressure side.
6. Work on removal, maintenance and storage can
now commence.
7.2. Removal
DANGER due to poisonous 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
physical protection equipment!
BEWARE 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!
NOTE
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.
Attention: 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 pres-
sure ports and the floor fixation on the hydraulics
housing and on the support.
4. Attach the lifting equipment to the correspond-
ing attachment points. To do this, you first have
to attach the enclosed transport shackle to
the pressure port. The hydraulics can then be
removed from the operating space.
