nance, transport etc.)! The end-user is respon-
sible for ensuring that all personnel follow these
instructions and guidelines.

2.2. General safety

• When installing or removing the pump, never
work alone in rooms and sump. A second person
must always be present.
• The pump must always be switched off before
any work is performed on it (assembly, disman-
tling, maintenance, installation). The pump must
be disconnected from the electrical system and
secured against being switched on again. All ro-
tating parts must have come to a stop.
• The operator should inform his/her superior
immediately should any defects or irregularities
occur.
• The end-user must shut down the equipment im-
mediately if defects occur that represent a safety
risk. These include:
• Failure of the safety and/or monitoring devices
• Damage to important parts
• Damage to electrical equipment, cables, and
insulation.
• Tools and other objects should be kept in their
designated places to ensure they can be used
safely.
• Sufficient ventilation must be provided in en-
closed rooms.
• When welding or working with electronic devices,
make sure there is no risk of explosion.
• Only use lifting equipment which is legally de-
fined as such and officially approved.
• The lifting equipment must be kept safely
and must be suitable for the conditions of use
(weather, hooking unit, load, etc.).
• Mobile equipment for lifting loads should be
used in such a way that it is guaranteed to remain
stable during operation.
• When using mobile equipment for lifting
non-guided loads, take action to prevent tipping,
shifting, sliding, etc.
• Measures should be taken to ensure that no
person is ever directly beneath a suspended
load. Furthermore, it is also prohibited to move
suspended loads over workplaces where people
are present.
• If mobile equipment is used for lifting loads,
a second person should be present to coordinate
the procedure if required (for example, if the
operator's field of vision is blocked).
• The load to be lifted must be transported so that
no-one will be injured if there is a power failure.
Furthermore, if such work is being carried out
outdoors, it must be cancelled if the weather
conditions worsen.
These instructions must be strictly observed.
Non-observance can result in injury or substan-
tial material damage.
