몇 CAUTION
Do not screw the safety lock onto the
appliance during decalcification.
Do not use the steam cleaner as long as
there is decalcifying agent in the boiler.
Be careful when filling and draining the
steam cleaner with the decalcifying so-
lution. The decalcifying solution can
corrode sensitive surfaces.
몇 CAUTION
Symbols depending on unit type.
Please read the operating in-
structions!
몇 CAUTION
Safety devices protect the user and must
not be modified or bypassed.
The pressure controller keeps the boiler
pressure during the operation as constant
as possible. The heating is turned off if the
maximum operating pressure of 4 bar is
reached in the boiler and is reactivated in
case of a pressure drop in the boiler due to
steam tapping.
The safety thermostat turns off the appli-
ance if the pressure controller fails and the
appliance overheats in case of a malfunc-
tion. Please contact your local KÄRCHER
customer service to arrange for the reset of
the safety thermostat.
The safety lock seals the boiler against the
steam pressure that builds up in the boiler.
If the pressure controller is defect and the
steam pressure in the boiler rises, a pres-
sure control valve in the safety lock opens,
and steam is emitted through the lock to the
outside.
Please contact your local KÄRCHER cus-
tomer service before you put the appliance
into operation again.
