Safety
Have maintenance and repair work carried out by qualified skilled
personnel only!
It is recommended to have the pump serviced and checked by Wilo
after-sales service.
DANGER! Risk of fatal injury!
There is risk of fatal injury from electrical shock when working on
electrical equipment.
• Work on electrical equipment may only be done by electricians
approved by the local electricity supplier.
• Before working on electrical equipment, switch it off and secure it
against being switched on again.
• Follow the installation and operating instructions for the pump,
level control device and other accessories.
DANGER! Risk of fatal injury!
Contact voltage hazardous to human life.
Work on the terminal boxes may only be started once 5 minutes
have passed, due to the dangerous residual contact voltage
(capacitors).
• Before working on the pump, disconnect the power supply and
wait for 5 minutes.
• Check whether all connections (including potential-free contacts)
are voltage-free.
• Never use an object to poke around the openings on the terminal
box and never insert anything into the terminal box!
DANGER! Risk of fatal injury!
Failure to install safety devices on the motor, terminal box or on
the coupling can cause electrical shock or contact with rotating
parts, potentially resulting in life-threatening injuries.
• Before commissioning and after maintenance work, all safety
devices (such as terminal box covers or coupling covers) that were
removed must be reinstalled.
• The tools used during maintenance work on the motor shaft (such
as an open-end wrench) can be flung out if they come into contact
with rotating parts and cause serious or even fatal injuries.
• The tools used during maintenance work must be removed com-
pletely before the pump is started up.
• Keep a safe distance during commissioning.
• Always wear protective clothing, protective gloves and protective
goggles when working.
WARNING! Risk of injury due to the weight of the pump!
The pump itself and pump parts can be extremely heavy. Falling
parts pose a risk of cuts, crush injuries, bruises or impacts, which
may lead to death.
• Always use suitable lifting equipment and secure parts against fall-
ing.
• When performing installation and maintenance work, protect the
pump components against falling.
• Never stand underneath a suspended load.
DANGER! Risk of burns or freezing to the pump when body parts
come into contact with the pump!
Depending on the pump or system operating conditions (fluid tem-
perature), the entire pump can become very hot or very cold.
• Keep a safe distance during operation!
• In the case of high water temperatures and system pressures, allow
the pump to cool down before all work.
