Kärcher CW 3 Manual

30 EnglishPrespraying (remove insects)Foam is applied to the front half of the vehicle by the presprayingnozzles. The foam is generated from water, prespraying agentand compressed air.Intensive BasicPre-cleaning chemicals are applied to the vehicle by stationarynozzles.The foam is generated from water, prespraying agent and com-pressed air.Wheel rim foamCompressed air is used to spray a water-cleaning agent mixtureonto the wheel rims via 2 stationary foam nozzles.High-pressure washThe high-pressure wash removes coarse dirt from the surface ofthe vehicle. High-pressure cleaning minimises the danger ofscratching from sand grains or similar abrasives and makes a sig-nificant contribution to preserving the paintwork during cleaning.Various different versions are available:● Working pressure 16 bar (1.6 MPa)● Working pressure 60 bar (6 MPa)● Working pressure 70 bar (7 MPa), on-board high-pressurepump (in the portal)Foam waxFoam wax is applied to the vehicle by the drying aid nozzles be-fore the drying process.Cold waxWater mixed with wax is sprayed onto the vehicle via the cold waxnozzles. Two different types of cold wax (wax 1 and wax 2) canbe selected.Cleaning agent heaterThe cleaning agent heater is located in the cleaning agent supplyin pillar 2.Frost protection deviceThe washing bay can be equipped with a frost protection device:If there is a danger of frost, the water is blown out of the pipingsystem automatically.This blowing process is controlled by a thermostat.Reverse osmosis systemDemineralised water (from an on-site system or optionally avail-able reverse osmosis system) or fresh water dosed with dryingaid is sprayed onto the vehicle via the drying aid nozzles.Foam polishingA compressed air foamed mixture of water and cleaning agent issprayed onto the vehicle via 2 stationary nozzles. This is followedby a polishing procedure with the washing brushes.Safety switchSafety switches are required if the required safety clearances be-tween the washing bay and permanent fixtures (e.g. walls, pillars,sinks) cannot be maintained. The safety switches prevent per-sons from being crushed between the system and the wall.The washing bay stops immediately if a safety switch touches anobstacle.NoteIf the system is stopped by a safety switch, determine the causeif this hand have the safety switch reset by an authorised techni-cal specialist.Splash guardThe splash guard protects the areas adjacent to the washing sta-tion from sprayed dirt and splash water emitted by the rotatingside brushes.The splash guard is attached to the outer surfaces of the chassisand suspension as well as the pillars.Bollard protectionThe purpose of the bollard protection is to ensure central align-ment of the vehicle. They prevent the vehicle from being parkedtoo far away from the centre.Remote resetThe Reset function allows the wash gantry to be moved to the in-iial position remotely with a command via an interface. The func-tion can be enabled via a separate parameter in the systemcontrol.● This function must only be enabled in countries or at locationswhere this function is permitted.● Video surveillance must be installed on site, covering the en-tire area of the washing hall or the entire travel path of the sys-tem, and any regulations applicable in the country/municipalitywhere the system is installed must be applied.● The person who performs the remote reset must first ensurevia the video surveillance that there are no persons in the trav-el path of the system. If a person then requests the command,that person must confirm that the system and its travel pathare completely free by acknowledging a safety notice (e.g.pop-up window).● The person who integrates the system into his system, e.g. viathe Internet, is responsible for the required security or cyber-security and a risk assessment must be carried out on the sys-tem.Gate controlThe on-site gate control is actuated by the passenger vehicle por-tal controller with the correct signals according to the washing se-quence.A distinction is made between summer gate control and wintergate control.Summer gate control● The gates are open before washing starts.● The vehicle can drive in.● The gates are closed when washing starts.● The gates are opened when washing ends and remain open.Winter gate control● The entry gate is closed before washing starts and must beopened to allow the vehicle to drive in. This is done by e.g. in-serting a wash card into the wash card reader.● The gates are closed when washing starts (e.g. by pressingthe "Start" button on the wash card reader).● The gates are opened when washing ends and are closedagain after the vehicle has exited.Control elementsEmergency offIn the event of danger to persons, equipment or animals, the sys-tem must be switched off immediately by pressing the "EMER-GENCY OFF" button."EMERGENCY OFF" buttons are located:● On the wash card/code reader.● On the control panel.● Optionally at the washing hall entrance if the control panel orwash card/code reader are not located at the entrance.Main switchThe main switch is located at the main supply distributor.Set the main switch to "1" to switch the system on.ABS payment systemAt the key switch on the main supply distributor, see Supply dis-tributorcan be used for selecting the operating stations fromwhich washing programs can be started.● Position 0: Programme start not possible● Position 1: Programme start possible at the wash card/codereader● Position 2: Programme start possible at the wash card/codereader and at the control panel
