Safety Devices - Kärcher DE 4002 Bedienungsanleitung

Safety Devices

Safety devices serve for the protection of
the user and must not be put out of opera-
tion or bypassed with respect to their func-
tion.
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.
Water shortage thermostat
When the water in the boiler becomes ex-
hausted, the temperature of the heating in-
creases. The low-water thermostat turns off
the heating, and the red low-water indicator
lamp "water shortage" lights up. The heat-
ing is prevented from being turned on again
until the boiler has cooled down or been re-
filled with water.
Safety thermostat
If the low-water thermostat fails and the ap-
pliance overheats, the safety thermostat
turns off the steam cleaner.
Please contact your local KÄRCHER cus-
tomer service to arrange for the reset of the
safety thermostat.
Safety lock
The safety lock seals the boiler against the
steam pressure that builds up in the boiler.
If the pressure controller is defective and
the steam pressure in the boiler rises above
5.7 bar, a pressure 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.

Notes on the operation
Cleaning of Textiles
Prior to treatment with the steam cleaner,
always check the reaction of the textiles in
an inconspicuous location: Steam heavily
at first, then let dry and then check for col-
our or shape changes.
Cleaning of Coated or Lacquered
Be careful when you clean kitchen and liv-
ing room furniture, doors, parquet, lac-
quered or plastic-coated surfaces. The
wax, furniture polish, plastic surfaces or
paint can come loose or stains can be cre-
ated. Therefore, always clean these surfac-
es with a steamed cloth only.
Cleaning of Glass
In case of low outside temperatures, espe-
cially in the winter, warm up the window
pane by slightly steaming the entire glass
surface. This will prevent tensions on the
surface which might lead to glass break-
age.
