6. Safety devices
This steam cleaner is equipped with several safety
devices which provide multiple levels of safety. The
most important safety devices are described below.
6.1 Pressure controller
The pressure controller maintains the level of
pressure inside the boiler as constant as possible.
When the maximum operating pressure inside the
boiler of 3.2 bar is reached, the heater is switched
off. When steam is drawn off and the pressure
drops, the heater is switched on again.
6.2 Low-water thermostat
As the water in the boiler is used up, the
temperature of the heater increases. The low-water
thermostat switches the heater off and the red low-
water warning lamp (B7) illuminates. The heater is
prevented from switching on again until the boiler
has either cooled down or has been refilled with
water.
6.3 Safety thermostat
If the low-water thermostat fails and the cleaner
overheats, the safety thermostat will switch off the
cleaner. Contact your local Kärcher service agent
so that the safety thermostat can be reset.
6.4 Safety cap
The safety cap seals in the steam pressure as it
builds up inside the boiler. If the pressure controller
is defective and the steam pressure inside the
boiler rises above 5 bar, an overpressure valve
opens inside the safety cap and steam is
discharged into the open. Contact your local
Kärcher service agent before you attempt to use the
cleaner again.
5.2 Care of accessories
Allow all accessories to dry out thoroughly before
you store them for use another time.
Do not stand the floor nozzle (G1), hand nozzle
(F1) and circular brush (E1) on their bristles while
they are cooling down and drying out, otherwise
they could become deformed.
Floor cloth and terry-towelling slip-on have been
pre-washed and can be used immediately with the
steam cleaner.
Dirty floor cloths and terry-towelling slip-ons can be
placed in a washing machine at 60 °C and dried in a
tumble dryer. Do not use a liquid softener as this would
impair the ability of the cloths to pick up dirt.
5.3 What to do if a problem occurs
If a problem occurs with your steam cleaner, con-
tact your local Kärcher service agent (see enclosed
address list).
