– 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 attached at every tapping

point.

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

combustion 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.

ATTENTION

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.

DANGER

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.

Install Cekon plug on the connection cable of the appliance.

Insert Cekon plug into the socket.

To switch off the stationary high pressure cleaner, the Cekon plug

must be easily accessible so that it can be removed from the

mains.

Before using for the first time, cut off the tip of the lid of the oil

tank on the water pump.
