Twin-head pump operation
To ensure the standby pump is ready for operation, operate the standby pump every 24 h
at least once a week.
• Maintenance work: The technician must be familiar with the use of operating fluids and
their disposal.
• Electrical work: Electrical work must be performed by a qualified electrician.
• Installation/dismantling work: The installation/dismantling must be carried out by a
qualified technician who is trained in the use of the necessary tools and fixation materi-
als.
It is recommended to have the pump serviced and checked by the Wilo customer service.
DANGER
Risk of fatal injury due to electrical current!
Improper conduct when carrying out electrical work can lead to death
due to electric shock!
• Any work on electrical devices may only be carried out by a qualified
electrician.
• Before carrying out any work, disconnect the unit from the power
supply and secure it against accidental switch-on.
• Any damage to the pump connection cable should only ever be recti-
fied by a qualified electrician.
• Follow the installation and operating instructions for the pump, level
control device and other accessories.
• Never poke around in the motor openings or insert anything into
them.
• After completing the work, refit previously dismantled protective
devices, for example, terminal box covers or coupling covers.
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 as-
sembly 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 com-
pletely before the pump is started up!
