6.5 Preparing the installation
DANGER
Risk of fatal injury from falling parts!
The pump itself and pump parts can be extremely heavy. Falling parts pose a risk of
cuts, crush injuries, bruises or impacts, which can be fatal.
• Always use suitable lifting equipment and secure parts against falling.
• Never stand underneath a suspended load.
• During storage and transport, as well as before all installation and assembly work,
ensure that the pump is in a safe position and standing securely.
WARNING
Risk of personal injury and property damage due to improper handling!
• Never set up the pump unit on unfortified surfaces or surfaces that cannot bear
loads.
• Flush the pipe system if required. Dirt can cause the pump to fail.
• Install only after completion of all welding and soldering work and after the pipe
system has been flushed, if required.
• Observe the minimum axial distance of 400 mm between a wall and the fan cover
of the motor.
• Ensure free air access to the heat sink of the electronic module.
ƒ
The pumps must be protected from the weather and installed in a frost/dust-free,
well-ventilated environment that is not potentially explosive. Observe the instruc-
tions in “Intended use” [
} 114] section!
ƒ
Mount the pump in a readily accessible place. This makes it easier to complete in-
spections, maintenance (e.g. mechanical seal change) or replacement in the future.
ƒ
Install a device for attaching hoisting gear above the set-up site of large pumps.
Total weight of the pump: see catalogue or data sheet.
