– The heating appliance of the machine is an ignition plant.
Please follow the local regulations while installing it.
– Use only certified chimneys/exhaust pipes.

Danger
Scalding danger! This symbol must be displayed in each bleeder
area.
While installing a fuel tank for the heating oil in the machine in-
stallation room, please follow the regulations applicable to the
storage of inflammable fluids (can be acquired from Carl Hey-
manns Verlag, Cologne, www.heymanns.com).
Please follow the diagram given below for laying the fuel pipes.
It is necessary to provide a two-channel system - for the forward
and backward flow.
– Maximum starting pressure of the fuel: 0.05 MPa (0.5 bar)
– Maximum under-pressure between fuel filter and pump: 0.04
MPa (0.4 bar)

– Each appliance must be connected to a separate chimney.
– The exhaust system must be designed according to the local
rules and regulations after consulting the concerned chimney
expert.
We recommend the installation of a draught interceptor between
the plant and the chimney.
Note
The chimney draught specifications given in the technical data
must be maintained if you want to achieve the prescribed com-
bustion values.
– 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).

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.
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 28 MPa.
– The insulation of the pipes must be resistant to temperatures
until 155 °C.
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.


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).
 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.
