ṇ Steam cleaning electric household
appliances
„ If you use the appliance to clean electric
household appliances (e.g. electric kitch-
en ranges) these appliances must be off
circuit (switch off the fuse). Before you
use the appliances again make sure they
have dried completely. Please observe
the notes of the appliance manufactur-
ers!
„ Caution: The device should not be used
to clean electrical appliances such as ov-
en, exhaust, micro-wave, television,
lamps, hair-dryer, electrical heating sys-
tems, etc.
ṇ Maintenance
„ Turn off the appliance and remove the
mains plug prior to any care and mainte-
nance works.
„ Repair works may only be performed by
the authorized customer service.
ṇ
Storage
„ Caution: Never operate or store the ap-
pliance in a horizontal position!
„ Protect the unit from rain. Do not store
outside.
This steam cleaner is equipped with several
safety devices that provide an all-round pro-
tection of the appliance. The most important
safety devices are described in the follow-
ing.
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.
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 lights up. The heating is prevented
from being turned on again until the boiler
has cooled down or refilled with water.
If the boiler thermostat fails and the appli-
ance overheats, then the safety thermostat
turns off the appliance.
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 customer
service before you put the appliance into op-
eration again.
