Dispose of the cleaning fluid in accordance with the disposal regulations. SETTING OF THE ALTO AUTOMATIC SCALE ALARM SYSTEM The automatic scale alarm system is set at the factory to water hardness class 2. Should an adjustment be necessary, proceed as follows: Measure the water hardness or ask your water supply company. Set the number of drops per minute (see table) at the metering device (Fig. 13). Hardness °dH Drops/min. class 1 soft 0-7 10 2 mediumhard 7-14 20 3 hard 14-21 30 4 very hard >21 40 1°dH = 1,25°e = 1,79°f 1) Option / model variants 11 DX 845 W / DX 865 / DX 985 / TitanEnergy / TitanEnergy X GB DESCALING Descaling agents cause burns. Avoid contact with the skin, eyes and clothes. Wear appropriate protective clothing (e.g. gloves, face mask, apron). Only approved scale removers may be used for descaling. Use Alto Stone-EX, No. 81236 +With regular use of Alto Anti-Stone, descaling will normally not be necessary. Incorrect operation of the machine or the use of non-approved cleaning agents can cause deposits in the pipework system. Scaling is caused by the water hardness and is indicated by a gradual increase in the water pressure displayed on the pressure gauge. If the working pressure is exceeded by 10 bar (with the Vario- Press trigger gun open), the system must be descaled. Procedure: Unscrew the high-pressure nozzle from the spray lance and place separately in the Alto scale remover. Draw in Alto scale remover via the metering valve by hanging a cleaning agent hose into the scale remover bottle and setting the metering valve to maximum concentration. Hold the spray lance in a separate container to collect the discharged liquid. Switch on the high-pressure pump. Actuate the trigger gun. Alto scale remover is drawn in and emerges from the spray lance foaming vigorously after approx. 1 minute. Switch off the high-pressure pump and allow the scale remover to work for approx. 15 minutes. Flush out the pump system well with clean water. After approx. 2 minutes, a steady jet of water must emerge at the water outlet tube. If this is not the case, repeat the descaling procedure. Screw the high-pressure nozzle onto the spray lance. FROST PROTECTION If the high-pressure cleaner is stored in a room in which temperatures of below 0° C can occur, antifreeze must first be flushed through the pump. During the flushing process, actuate the trigger gun 2 or 3 times. In order to avoid any risk, the machine should preferably be stored for a short period in a heated room before it is put into service again. 1) Option / model variants 12 DX 845 W / DX 865 / DX 985 / TitanEnergy / TitanEnergy X GB CAUSE REMEDY ‡ Display does not light up, machine does not start ‡ Display flashes rapidly (5x per second), motor has cut out and will not start again ‡ Display is lit continuously ‡ Display is lit continuously ‡ Display flashes slowly (1x per second) ‡ Display flashes rapidly (5x per second), burner will not start again ‡ Machine stops and starts intermittently with the trigger gun open ‡ Machine stops and starts intermittently with the trigger gun closed ‡ Pressure too low ‡ Cleaning agent is not drawn in > Fault in the mains cable > Motor overheated > Anti-Stone concentrate container empty > Fuel tank empty > Contamination or water in fuel > Burner sooted > Inadequate water inlet > Cleaning agent tank empty > Pressure and volume controller or VarioPress trigger gun set too low > Flame sensor sooted > Fault in ignition or fuel system > High-pressure nozzle soiled > Machine scaled > Trigger gun leaking > High-pressure hose, high-pressure screw fitting or pipework leaking > Cleaning agent tank empty > High-pressure nozzle worn > Pressure and volume controller or VarioPress trigger gun set too low > Filter in water inlet clogged > High-pressure pump drawing in air > Suction or pressure valve of highpressure pump soiled or defective > Cleaning agent tank empty > Sludge in cleaning agent tank > Suction valve at cleaning agent inlet soiled Have electrical connection checked Clean or replace clogged highpressure nozzle Set the VarioPress control knob on the trigger gun to a higher pressure Possible phase failure; have electrical connection checked Top up anti-scale concentrate container Top up fuel tank Clean fuel tank and pipework Have burner setting checked Use water hose with at least 1/2" diameter, clean filter in water inlet Top up cleaning agent tank Set pressure and volume controller or VarioPress control knob on the trigger gun to a higher pressure Remove and clean Call service technician Clean or replace high-pressure nozzle Descale according to the instructions Inspect the trigger gun Retighten screw fittings, replace high-pressure hose or pipework Top up cleaning agent tank Replace high-pressure nozzle Set pressure and volume controller or VarioPress control knob on the trigger gun to a higher pressure Clean filter Repair leaks Clean or replace valves Top up cleaning agent tank ...
