Safety Devices; Safety Thermostat - Kärcher SC 4 Iron Kit Operating Instructions Manual

Descaling the boiler
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.
Steam iron
DANGER
 The steam pressure iron is hot and so is
the steam jet.
 Point out to other people the possible
risk of being scalded or burnt. Never di-
rect the steam jet at people or animals
(risk of scalding). Do not touch any
electrical leads or combustible objects
with the hot steam pressure iron.
 The steam pressure iron must not be
used if it has been dropped, shows vis-
ible signs of damage or if it leaks.
WARNING
 The steam pressure iron must be used
and placed on a stabile surface.

Safety Devices

CAUTION
Safety devices protect the user and must
not be modified or bypassed.
Pressure controller
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.
Boiler thermostat
If, in case of a malfunction, there is no wa-
ter in the boiler, the temperature in the boil-
er rises. The boiler thermostat turns off the
heating. Once the boiler is filled, normal op-
eration can continuet.

Safety thermostat

The safety thermostat turns off the appli-
ance if the boiler thermostat and the pres-
sure controller fails and the appliance over-
heats in case of a malfunction.
Please contact your local KÄRCHER cus-
tomer service to arrange for the reset of the
safety thermostat.
Maintenance lock
The maintenance lock acts as a pressure
control valve at the same time. It 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, the pres-
sure control valve, and steam is emitted
through the maintenance lock to the out-
side.
Please contact your local KÄRCHER cus-
tomer service before you put the appliance
into operation again.
