Warning
Observe regulations of water supplier.
According to the applicable regula-
tions, the appliance must never be
used on the drinking water supply
without a system separator. Use a
suitable system separator manufactured by
KÄRCHER; or, as an alternative, a system
separator as per EN 12729 Type BA. Water
flowing through a system separator is con-
sidered non-drinkable.
Caution
Always connect the system separator to
the water supply, never directly to the appli-
ance!
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).
ṇ Warning
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
The mains must be connected by an expe-
rienced technician and the requirements of
the IEC 60664-1 must be fulfilled.

Remove the 4 knurled scrwes from the
roof. The screws can be loosened fast-
er when you press the roof from the top.
 Push the chimney pipe upward until the
connection to the burner has been loos-
ened.
 Push the roof towards the door until it
protrudes out of the casing on the oppo-
site side.
 Remove the roof upward. Caution! Do
not damage the chimney
 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 burner.
ƽ
Danger
Risk of electrical voltage. Setting may only
be done by an electrician.

Determining the hardness of tap water:
– through the public water supply works,
– Using hardness testing set, order no.
6.768-004.
 Open the switch box at the operator
panel.
1 Speed potentiometer
 Locate the local water hardness in the
diagram.
 Extend the vertical line upward until the
curve for the corresponding point has
been reached.
 Draw a horizontal line from the intersec-
tion and read the setting value (A).
 Adjust the speed potentiometer to the
value that you have ascertained (A).
