DANGER
Danger of death from falling parts!
The pump itself and pump parts can have a very high net weight. Falling
parts pose a risk of cuts, crush injuries, bruises or impacts, which can be
fatal.
• Always use suitable lifting accessories and secure parts against falling.
• Never stand below a suspended load.
• During storage and transport, as well as before all installation and as-
sembly 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.
•
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 instructions in "In-
tended use" [" 120] section!
•
Mount the pump in a readily accessible place. This makes it easier to complete inspec-
tions, maintenance (e.g. mechanical seal change) or replacement in the future.
•
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.
WARNING
Personal injury and property damage due to improper handling!
Transport lugs mounted on the motor housing can tear out if the load is
too heavy. This can lead to serious injuries and damage to the product!
• Never transport the entire pump with the transport lugs attached to
the motor housing.
• Never use the transport lugs attached to the motor housing to separ-
ate or pull out the motor impeller unit.
•
Only lift the pump with approved lifting gear (e.g. block and tackle, crane). See also
"Transport and storage" section.
•
Transport lugs mounted on the motor housing are only permitted for transporting the
motor!
NOTICE
Simplify subsequent work on the unit!
• To ensure the entire unit does not have to be emptied, install shut-off
valves upstream and downstream of the pump.
