2.3 Safety instructions
Electrical current
DANGER! Electrocution hazard!
Immediate danger to life if live components are touched.
• Only allow qualified electricians to work on the electrical system.
• Before commencing work, switch off the power supply and secure it against
being switched on again.
• Never open the control module (6) and never remove control elements.
• Have defective connecting cables replaced immediately by a qualified
electrician.
Magnetic field
WARNING! Risk of fatal injury from magnetic field!
Highly magnetic components are fitted inside the pump; they can cause fatal
injury to people with medical implants if the pump is dismantled.
• Never remove the rotor.
Hot components
WARNING! Risk of burns!
Pump housing ( 1) and glandless pump motor (3) may become hot and result in
burns on contact.
• During operation, touch the control module (6) only.
• Allow the pump to cool down before commencing any work.
Hot fluids
WARNING! Risk of burns!
Hot fluids can result in scalding. Before installing or removing the pump, or
undoing the housing screws (2), note the following:
• Allow the drinking water system to cool down completely.
• Close shut-off devices or drain the drinking water system.
Damage to electronic components
CAUTION! Damage to electronic components!
Pulsed mains voltage can lead to damage to electronic components!
• Only operate the pump with sinusoidal AC voltage as stated on the rating plate
(4).
• Never operate the pump with phase angle control.
• When switching the pump on or off using an external control unit, deactivate
any voltage pulsing (e.g. phase angle control).
• For applications where it is not clear whether the pump is operated with pulsed
voltage, get the control/ system manufacturer to confirm that the pump is
operated with sinusoidal AC voltage.
• Switching the pump on/off via triacs/solid-state relays must be examined on a
case-by-case basis.
