Safety
▪ When working at a height of more than 1 m (3 ft) above the ground, use scaffolding
with a safety harness.
▪ Cordon off the working area around the scaffolding.
▪ Disconnect the device from the mains and secure it against being switched on again
without authorisation.
▪ All rotating parts must be at a standstill.
▪ Make sure that there is no risk of explosion when carrying out any work with electrical
devices.
▪ Only use properly functioning hoisting gear.
▪ Keep away from the hoisting gear's swivel range when hoisting the product.
▪ Toxic or asphyxiating gases may build up when working in closed rooms or buildings.
Ensure there is sufficient ventilation and observe protective measures according to
work regulations (examples):
– Measure the gas concentration before entering.
– Carry a gas detector with you.
– etc.
▪ The work area in which the device is used is not a recreational area. No persons are al-
lowed in the work area during operation.
▪ Wear protective equipment in accordance with the notice of the work regulations.
▪ The operator must immediately report any faults or irregularities to their line manager.
▪ If hazardous defects occur, the operator must immediately deactivate the device:
– Malfunction of safety and monitoring devices
– Damage to housing parts
– Damage to electrical equipment
▪ The propeller must not bump into fixtures or walls in the operating space. Observe
defined clearances to fixtures and basin walls in accordance with consulting docu-
ments.
▪ If the water level significantly fluctuates, ensure the required water immersion using
level monitoring.
▪ Under normal operating conditions, the sound pressure level of the device is below
85 dB(A). However, the actual sound pressure level depends on several factors:
– Installation depth
– Installation type
– Utilisation
– Immersion depth
▪ Risk of injury through crushing and hot operating fluid. Wear the following protective
equipment:
– Closed safety goggles
– Protective gloves
– Safety shoes
▪ Always carry out maintenance tasks outside the operating space.
▪ Only carry out maintenance tasks mentioned in these installation and operating in-
structions.
▪ Use only original parts from the manufacturer for maintenance and repairs. Use of parts
other than the original parts releases the manufacturer from any liability.
▪ Collect any drips of fluid and operating fluid immediately and dispose of them according
to locally applicable guidelines.
Changing operating fluid
In the event of a motor defect, pressure of several bar can build up in the sealing
chamber! This pressure is released when the screw plugs are opened. If screw plugs are
opened without due caution, they can be ejected at high speed! To avoid injuries, ob-
serve the following instructions:
▪ Adhere to the prescribed sequence of work steps.
▪ Unscrew the screw plugs slowly, but never unscrew them completely. As soon as pres-
sure is released (audible whistling or hissing of air), stop turning the screw plug any fur-
ther.
WARNING! Hot operating fluids can also spray out when pressure is released. This
can result in scalding! To avoid injuries, allow the motor to cool down to the ambient
temperature before carrying out any work!
▪ When the pressure has been completely released, fully unscrew the screw plug.
The seal housing is filled with white oil. Replace the operating fluid during regular main-
tenance work and dispose of it according to the local guidelines.
