Assembly
ATTENTION
Always keep the installation site of the system well ven-
tilated to protect the machine against over-heating.
–
The appliance should not be directly attached to
the network of water and high pressure pipes. It is
mandatory to install the connecting hoses.
–
A shut-off tap must be installed between the main
water supply and the connecting hose.
Installing the high pressure connections
For installation, please follow the specifications of the
VDMA sheet 24416 "High pressure cleaners; fixed high
pressure cleaning systems; concepts, requirements, in-
stallation, testing" (the German version can be procured
from Beuth Verlag, Cologne, www.beuth.de).
–
The pressure loss in the pipe connections must lie
below 1.5 MPa.
–
The completed pipe connections must be checked
using 32 MPa.
–
The insulation of the pipes must be resistant to
temperatures until 100 °C.
Water supply
ATTENTION
Risk of damage to the plant if water supply is not of suit-
able quality.
Note: Impurities in the inlet water can damage the unit.
Kärcher recommends a water filter with a mesh width of
< 80 µm.
Quality requirements for tap water:
pH value
6.5...9.5
electrical conductivity
< 2000 µS/cm
removable materials
< 0.5 mg/l *
filterable materials (grain size be-
< 20 mg/l
low 0.025 mm)
Hydrocarbons
< 20 mg/l
Chloride
< 300 mg/l
Calcium
< 85 mg/l **
Total hardness
< 15 °dH **
Iron
< 0.5 mg/l
Manganese
< 0.05 mg/l
Copper
< 0.02 mg/l
free of bad odours
* Test volume 1litre, Settling time 30 minutes
** decalcification measures are necessary if the values
are higher
The water inlet is to be connected to the main water
supply using a water hose.
–
The water supply must have a minimum output of
4000 l/h for HDC 40/XX, 6000 l/h for HDC 60/XX,
8000 l/h for HDC 80/XX at minimum 0.15 MPa.
–
Appliances without prepressure pump: The water
temperature must lie below 60 °C.
–
Machines with prepressure pump: The water tem-
perature must lie below 85 °C.
Electrical connection
Note: Operating procedures create short term power
sinkings. During unfavorable net conditions other devic-
es might be disturbed.
ATTENTION
The highest allowed net impedance at the electrical
connection point (refer to technical data) is not to be ex-
ceeded. In case of confusion regarding the power im-
pedance present on your connection, please contact
your utilities provider.
–
For connection values, see technical data and type
plate.
–
The electrical connections must be done by an
electrician according to IEC 60364-1.
–
Current-carrying parts, cables and appliances in
the working area must be installed in a defectless
state and must be protected against water sprays.
DANGER
To avoid accidents due to electrical faults we recom-
mend the use of sockets with a line-side current-limiting
circuit breaker (max. 30 mA nominal tripping current).
