DANGER
Risk of fatal electrical shock! Generator or turbine operation during
pump flow!
Even without the electronic module (without electrical connection), there may be
dangerous contact voltage at the motor contacts!
• Check for absence of voltage and cover or cordon off adjacent live parts!
• Close the shut-off devices upstream and downstream of the pump!
DANGER
Potentially fatal injury due to electronic module not being installed!
A life-threatening voltage may be present at the motor contacts!
Normal operation of the pump is only permitted with the electronic module installed.
• Never connect or operate the pump without the electronic module mounted!
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.
DANGER
Risk of fatal injury due to ejected tools!
The tools used during maintenance work on the motor shaft can be thrown away if
they come into contact with rotating parts. Injuries and even death are possible!
• The tools used during maintenance work must be removed completely before the
pump is started up!
WARNING
There is a risk of burns or freezing upon coming into contact with the
pump/system.
Depending on the pump and system operating conditions (fluid temperature), the
entire pump can become very hot or very cold.
• Keep a safe distance during operation!
• Allow the system and pump to cool to room temperature!
• Always wear protective clothing, protective gloves and protective goggles when
working.
18.1
Air supply
Check the air supply to the motor housing and electronic module at regular intervals.
Dirt impairs the cooling of the motor. If necessary, remove dirt and restore unrestricted
air supply.
18.2
Maintenance tasks
DANGER
Risk of fatal injury from falling parts!
Falling pumps or individual pump components may result in life-threatening injuries!
• During installation work, secure pump components against falling down with
suitable lifting gear.
