Electrical Connection - Kärcher HDS 9/16-4 ST Gas Instructions Manual

Type C43
Gas appliance with combustion air inlet and exhaust system to be
connected to an exhaust system.
Type C53
Gas appliance with separate combustion air inlet and exhaust
system. The inlets are located in different pressure ranges.
Note: The chimney draught specifications given in the technical
data must be maintained if you want to achieve the prescribed
combustion values.
Drainage of condensate
The condensate pipes must be siphoned directly at the conden-
sate connection. The siphon height must be 30 cm. The siphon is
included in the scope of delivery. The condensate pipe must not
be firmly connected to the drainage system. The condensate
must first flow out freely into a funnel or a neutralisation container.
Before installing, please check the load-bearing capacity of
–
the wall. The fastening material delivered with the plant is
suitable for concrete walls. Use suitable anchor plugs and
screws for hollow component walls, brick walls and gas con-
crete walls - for e.g. injection anchor (for drilling diagram see
the specifications sheet).
Figure 3 - items 19 and 25
–
The appliance should not be directly attached to the network
of water and high pressure pipes. It is mandatory to install the
connecting hoses.
Figure 3 - A
–
A shut-off tap must be installed between the main water sup-
ply and the connecting hose.
Installing the high pressure connections
All national laws and regulations about installation of electrical
appliances must also be followed when installing high pressure
lines.
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.
Install the detergent tank
Figure 3 - Pos. 20
The tanks are to be installed in such a way that the lower level
mirror of the detergent should not be more than 1.5 m under the
machine floor and the upper level mirror should not be located
above the machine floor.
Figure 3 - B and item 19
 The water inlet is to be connected to the main water supply
using an appropriate water hose.
The water supply must have a minimum output of 1300 l/h at
–
minimum 0.1 MPa.
The water temperature must lie below 30 °C.
–
Caution
The highest allowed net impedance at the electrical connection
point (refer to technical data) is not to be exceeded. In case of
confusion regarding the power impedance present on your con-
nection, please contact your utilities provider.
Note: Operating procedures create short term power sinkings.
During unfavorable net conditions other devices might be dis-
turbed.
For connection values, see technical data and type plate.
–
The electrical connections must be done by an electrician ac-
–
cording to IEC 60364-1.
Current-carrying parts, cables and appliances in the working
–
area must be installed in a defectless state and must be pro-
tected against water sprays.
To avoid accidents due to electrical faults we recommend the use
of sockets with a line-side current-limiting circuit breaker (max.
30 mA nominal tripping current).
Firmly installed electrical connection
 Establish the electrical connection.
A main switch that can be locked (figure 3 - item 6) is to be in-
stalled at a safe and easily accessible place to switch off the sta-
tionary high pressure cleaner.
The contact opening of the main switch must be minimum 3 mm.
