– mechanic of Kärcher
– or an from Kärcher authorized individu-
al
ṇ
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, plane surface with firm base
admeasuring 1040 x 725 mm.
– For electrical connection refer to techni-
cal specifications.
– By customer, lockable, access for the
wash customer emergency - off- main
switch.
– Light at the washing area according to
the national requirements, in order to
assure safe working for the customer
when dark.
– Power and water supply according to
the measuring sheet.
– Drain water shaft and required drain
water disposal.
– Drill fixing holes according to the meas-
ure sheet.
Unpack the equpiment and dispose of the
packing material properly.
 Line up the equipment on the level ar-
ea.
 Fix with the material included. Use the
inclosed spacer and set up the equip-
ment horizontal.

2 Unterlegplatte 5 mm (4x) Unterlegplatte
2 mm (4x)
3 Washer 10,5 (4x)
4 Hexagon screw M10 (4x)
 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
external side of the plant.
 Connect high pressure hose to hand
spray gun
 Connect ray tube to hand spray gun
 Tighten all covering nuts firmly by hand.
Note
Impurities in the inlet water can damage the
unit. Kärcher recommends the use of a wa-
ter filter (see "accessories").
To ensure frost protection of the plant, the
water inlet must be protected against freez-
ing (through insulation and accompanying
heating).
Caution
Risk of damage to the plant if water supply
is not of suitable quality. Use water only of
potable quality as water supply to the plant.
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.
ƽ
Danger
Risk of electric shock!
The mains must be connected by an expe-
rienced technician 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.
ṇ
Warning
The highest allowed net impedance at the
electrical connection point (refer to techni-
cal data) is not to be exceeded. In case of
confusion regarding the power impedance
present on your connection, please contact
your utilities provider.

Unscrew the 4 screws on the cover of
the switching cabinet and remove the
cover.
 Connect the wire to the electrical switch
cabinet.
Note
After completion, check that the electrical
connection has the correct three-phase
connection.

Check the rotation direction of the high
pressure pump. With correct direction
of rotation a strong airflow can be felt
out of the exhaust opening of the burn-
er.
ƽ
Danger
Risk of electrical voltage. Setting may only
be done by an electrician.
Note
The following water hardness settings are
done at the time of delivering the plant:
 Determining the hardness of tap water:
– through the public water supply works,
– Using hardness testing set, order no.
