- 14– The heating appliance of the machine is an ignition plant.Please follow the local regulations while installing it.– Use only certified chimneys/exhaust pipes. DangerScalding danger! This symbol must be displayed in each bleederarea.While installing a fuel tank for the heating oil in the machine in-stallation room, please follow the regulations applicable to thestorage 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 forwardand backward flow.– Maximum starting pressure of the fuel: 0.05 MPa (0.5 bar)– Maximum under-pressure between fuel filter and pump: 0.04MPa (0.4 bar)Suction pipe length in mSuction height in mPossible suction pipe length in pipes with NW 8– Each appliance must be connected to a separate chimney.– The exhaust system must be designed according to the localrules and regulations after consulting the concerned chimneyexpert.We recommend the installation of a draught interrceptor betweenthe plant and the chimney.NoteThe chimney draught specifications given in the technical datamust be maintained if you want to achieve the prescribed com-bustion values.– Before installing, please check the load-bearing capacity ofthe wall. The fastening material delivered with the plant issuitable for concrete walls. Use suitable anchor plugs andscrews for hollow component walls, brick walls and gas con-crete walls - for e.g. injection anchor (for drilling diagram seethe specifications sheet).– Figure 3 - items 19 and 23The appliance should not be directly attached to the networkof water and high pressure pipes. It is mandatory to install theconnecting hoses.– Figure 3 - AA shut-off tap must be installed between the main water sup-ply and the connecting hose.All national laws and regulations about installation of electricalappliances must also be followed when installing high pressurelines.– 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 temperaturesuntil 155 °C.Figure 3 - Pos. 20The tanks are to be installed in such a way that the lower levelmirror of the detergent should not be more than 1.5 m under themachine floor and the upper level mirror should not be locatedabove the machine floor.Figure 3 - B and item 19 The water inlet is to be connected to the main water supplyusing an appropriate water hose.– The water supply must have a minimum output of 1300 l/h atminimum 0.1 MPa.– The water temperature must lie below 30 °C.CautionThe highest allowed net impedance at the electrical connectionpoint (refer to technical data) is not to be exceeded. In case ofconfusion 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 workingarea 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 useof sockets with a line-side current-limiting circuit breaker (max.30 mA nominal tripping current).Installing the plantOnly for authorised technicians!GeneralReplace high pres-sure nozzle withsteam nozzle if work-ing temperature isabove 100 °C.Fuel tank for heaterFuel pipesSmoke pipe!Wall mountInstalling the high pressure connectionsInstall the detergent tankWater supplyElectrical connection35EN
