is not of suitable quality. The system must
only be supplied with water in drinking water quality.
The plant may be used for diverting combustible gases only in the open.
If the plant is to be housed under a roof or
in a closed room, then it must be connected
to a chimney to provide an outlet for the exhaust gases. If the plant is to be connected
to a chimney, then the burner needs to be
adjusted and the exhaust values must be
checked by the concerned chimney cleaner.
ATTENTION
The system is frost-safe up to -20°C under
the conditions outlined in the section
"Frost-protection" and must be shut down if
the temperatures fall below this limit.

3 Inspection opening
Close the lid of the filling nozzle.
Fill fuel till the filling level display indi-
cates full level.
Note:
Ensure that no fuel overflows and goes into
the inspection opening. This fuel can be
taken for a leakage during subsequent inspection.
Close the filling nozzle.
ATTENTION
Risk of functional disturbances. While filling
the softening salts, use only the softening
salt in the tablet form listed in the chapter
"Accessories".
Open the salt tank.
Fill the softening salt right until the top.
Close the salt tank.
Note:
An empty salt tank will cause a malfunction!
Fill the salt tank at the latest when water is
visible in the salt tank while removing the
lid. Filling the salt container to the top does
not mean that there will be an increase in
salt consumption.
When the system is functioning properly,
the ratio of salt consumption to water consumption remains constant.
We recommend documenting the salt and
water consumption in an operations log.

몇 WARNING
Risk of accident due to ice formation. In
case of ice formation the plant must be
closed off to prevent ice-related accidents.
Note:
The following functions are guaranteed:
– Unrestricted washing with the high-
pressure spray lance up to -15°C.
For systems with 4 washing stations it is
recommended to lock one washing sta-
tion at temperatures below -10 °C (for
systems with 4 high-pressure modules
type 908 already at a warmer tempera-
ture).
– Restricted washing operations using
washing brush at temperatures sub-
zero temperatures.
During restricted washing, all washing
brushes must be checked for ice-forma-
tion at regular intervals. Foam wash
with frozen washing brushes can dam-
age the vehicle. Take the following
steps if the washing brushes are frozen:
– The system is frost-safe up to -20°C.
The device must be shut down at tem-
peratures below -20°C in accordance
with the instructions in "Shutdown in
case of frost".

Frost protection
14 EN
- 13
Note:
The pre-requisites for frost protection are:
– The main switch must be in position 1.
– The doors of the system must be
closed.
– Uninterrupted power, water and fuel
supply must be ensured.
– Water supply must also be protected
against freezing.
– The fuel supply must be protected
against frost (e.g. heating cartridge in
the tank, trace heating),
– Instructions for assembling and installa-
tion are given in chapter "Installing the
plant".
– The hot air ventilators have been set
correctly.
– All maintenance steps according to
"Maintenance and Care" have been
carried out correctly.
– All cleaning tools are placed back in the
storage compartment.
– The trigger guns with frost protection
holes that are part of the system are installed.
Note:
The washing place heating can function
properly provided the washing area has
been built properly according to the
KÄRCHER recommendations.
The heating power is sufficient for a heated
washing station surface of 50/60* m
2
. If the
heated surface exceeds this value, the frost
protection cannot be guaranteed.
Snow layers and large volumes of ice pieces fallen from the vehicles require a very
high heating capacity. It is necessary to remove these deposits.
* 50 m

with gas burner (64 kW); 60 m2 with
oil burner (72 kW); with 4 high-pressure
modules type 908 the washing station surface must be further reduced.
Before the onset of the frost period,
maintenance tasks must be carried out
"every year before the onset of the forst
period" according to section "Maintenance and Care".
Carry out the following tasks for keep-
ing the frost protection intact.
Note:
Maintenance not being done on time or
from experts will mean, that there is no
guarantee concerning frost damage.
