Installation and operating instructions Wilo-Stratos PICO-Z
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.
Warning: Risk of scalding!
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 com-
pletely.
• Close shut-off devices or drain the drinking water
system.
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 con-
trol/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.
