36 English 5.906-590.0 Rev. 01 (05/17)From the fresh water container, water is pumped into thesteam boiler using the boiler pump.The water is heated.When operating the steam switch on the handle, thevalves on the steam boiler open.The steam flows through the socket into the connected ac-cessory.The steam boiler temperature is monitored. The steamboiler is switched off by the pressure switch when the nom-inal pressure has been reached.A pressure relief valve protects the steam boiler. Over-pressure media (water / steam) are dissipated via a hoseand a drilled hole in the base support.As long as the suction mode is switched off, both heaterswill run (2kW & 1kW), USA device (1.2kW & 0.4kW). If thesuction turbine is switched on, the 1kW heater will switchoff. This ensures a higher network utilisation during thepure steam operation.1 Solenoid valveright2 Water pump3 Solenoid valveleft4 Boiler pumpIf cold water is set at the handwheel, the water pump willdeliver water through the steam hose and to the connectedup accessories in combination with the right-hand solenoidvalve.If warm water is set at the handwheel, the water pump willdeliver water, which is mixed with steam from the boiler inorder to heat it up, in combination with the right-hand sole-noid valve. To do that, the left-hand solenoid valve on theboiler opens.The water/chemical pump only delivers chemicals if thedetergent/vacuuming operation operating mode has beenselected on the control panel rotary switch.The left-hand solenoid valve is opened in this selection po-sition.030 Function
