Operating instructions

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 in-
stalled.
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 piec-
es fallen from the vehicles require a very
high heating capacity. It is necessary to re-
move these deposits.
* 50 m
2
with gas burner (67 kW); 60 m
2
with
oil burner (72 kW); with 4 high-pressure
modules type 908 the washing station sur-
face 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 "Mainte-
nance 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.

Target value: approx. 0.5 l/min per washing tool
Water quantity is higher: Change the node piece in the hand-spray
gun.
몇 WARNING
Risk of injury and damage. If the frost protection water volume is big-
ger than the admissible value, the cleaning tool may move uncon-
trollably due to the exiting water stream. If the frost protection water
volume is too big, replace the union piece in the trigger gun by all
means.
Water quantity is lesser Clean filter for frost protection pump; clean
sieve in throttle, clean pipes, check the rotation direction of the
pump.
