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 interrceptor 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). 

–

Figure 3 - items 19 and 23

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. 

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).

Installing the plant

Only for authorised technicians!

sure nozzle with 
steam nozzle if work-
ing temperature is 
above 100 °C.
