Note:
The equipment may only be installed by
– KÄRCHER service engineers
– persons authorized by KÄRCHER
몇 WARNING
Please ensure that there are no exhaust
emissions near the air inlets.
Sufficient ventilation is very important and
exhaust gases must be ventilated as in-
structed by local regulations.
The following requirements are necessary
in order to install the equipment:
– Horizontal, even foundation according
to separate drawing (ask for it at
KÄRCHER).
– For electrical connection refer to techni-
cal specifications.
– For water connection refer to technical
specifications.
– Ensure adequate insulation / heating
for water and fuel pipes while operating
in winter.
– Drain water shaft and required drain
water disposal.
– Adequate lighting at washing place to
ensure safe working for the customers
using the washing system.
Unpack the equpiment and dispose of the
packing material properly.
 Align the system on an even and hori-
zontal installation site using the adjust-
ing screws on the base frame.
 Place the exhaust nozzle from outside
on the roof and fasten it from inside us-
ing the enclosed screws.
 Connect the high pressure hose to the
system.
 Connect high pressure hose to hand
spray gun
 Connect spray lance to trigger gun.
 Tighten all covering nuts firmly by hand.
To disconnect from the drinking water net-
work, a system separator type BA, catego-
ry 4 must be installed between the system
and the drinking water network. In addition
to that, the local regulations must be ad-
hered to.
Note:
Impurities in the inlet water can damage the
system. Kärcher recommends the use of a
water filter (see "accessories").
ATTENTION
Risk of damage to the plant if water supply
is not of suitable quality. The system must
only be supplied with water in drinking wa-
ter quality.
Quality requirements for tap water:
For connection values refer to technical
specifications.
 Insert the inlet hose from the bottom
through the plant opening and connect
it.
When a water distributor block 4. type of
water is used, processed water can also be
used with certain washing programmes.
Requirements on the quality for processed
water:
 DANGER
Risk of electric shock!
The mains must be connected by an expe-
rienced electrician and the requirements of
the IEC 60664-1 must be fulfilled.
The plant must be secured through a wrong
current protection switch with a triggering
current lesser than or equal to 30 mA.
Note:
A clearly noticeable EMERG STOP switch
must be installed in the supply line to the
system, which can be used to turn the en-
tire system off.
 After connecting the ssytem, check the
rotating direction of the warm water cir-
culation pump and the circulation pump
for heating the washing place (option-
al).
Note:
The maximum permissible vacuum in the
fuel pipe (measured between the fuel filter
and the fuel pump) is 0.4 bar.
The underpressure depends on:
– Length of pipe
– Suction height
– Fixtures, branchings and angles in the
suction pipe (dotted line in the diagram)
– Pipe cross-section (from +4°C the heat-
ing oil EL will separate the paraffin that
will then get deposited on the insides of
the pipe)
– Viscosity of the heating oil (depending
on temperature)
Measures against very high level of under-
pressure are:
– Minimum inner diameter of pipe 6 mm
– Short, straight pipes (as far as possible)
– Maximum viscosity 4...6 cSt at 20°C
– In extreme cases, use separate fuel
pipe with pump
– Pre-heat the heating oil; use heating for
the suction pipe
– Use heating oil with additives (flow pro-
moters) (winter heating oil) if there is
risk of frost
