of the function of the appliance. When
steam is not being used, engage the
steam lock.
To continue steam delivery, return the
switch to its original position.
• Always use the appliance with the sa-
fety cap supplied or an original replace-
ment part. Using non-original Polti sa-
fety caps can lead to accidents.
• When accessing the pressurised boiler
(removing the cap, filling up), ensure
that the appliance has been switched
off at the power switch and disconnec-
ted from the mains for at least one
hour, allowing it to cool. There is a risk
of accidents while the boiler is a swit-
ched on/hot and pressurised.
• Do not connect the appliance with the
safety cap removed. Carefully tighten
the safety cap before plugging in and
turning on the appliance.
• Before turning on the appliance, check
that there is nothing blocking the
mouth of the boiler (filler bottle, funnel,
or other objects), and that the safety
cap is closed.
• Check that the safety cap is correctly ti-
ghtened; if steam is escaping from the
cap, switch off the boiler, unplug the
power cable, wait for one hour for the
appliance to cool, and then unscrew.
Check the condition of the safety cap
and seal. If the cap is in good condition,
screw it back on completely. If steam
continues to escape from the cap, take
the appliance to the nearest authorised
service centre.
• Periodically check the condition of the
safety cap and seal. Impact and being
dropped may compromise the safety of
the cap. Replace with an original spare
part or replace the seal.
• If the cap spins freely, this indicates that
the boiler is still pressurised and there-
fore hot. Never force the cap open,
whether the appliance is switched on or
the boiler is switched off and the ap-
pliance is disconnected from the mains.
Always wait for the boiler to cool, ope-
ning the cap without force.
• Do not use tools to unscrew the cap. If
the cap cannot be removed, even once
the appliance has cooled, go to your
nearest authorised service centre.
• WARNING
Never fill the boiler as
soon as the safety cap has been opened
when the boiler is still hot, even if the
appliance is unplugged from the mains.
On contact with the hot, empty boiler,
cold water will evaporate producing a
spray of steam which can cause burns.
Only fill the boiler when cold and al-
ways keep your face away from the boi-
ler mouth when filling.
• The use of non-original Polti caps and
disregard for the instructions in this ma-
nual constitutes improper use. Polti
S.p.A. declines all liability for any acci-
dent deriving from any improper use of
this appliance.
