1.5 Unit operation
Main subassembly I - Drive motor with high-pressure pump, safety control block with automatic pressure
switch-off feature, flow monitor and high-pressure blower burner with fuel pump
• The float valve controls the water supply.
• The high-pressure pump sucks water out of the water box and transports the water under pressure to
the high-pressure nozzle.
• The safety control block with automatic pressure switch-off feature and safety valve ensures pressure
monitoring and limitation.
• The automatic calcification alarm G meters the anti-calcification concentrate.
• The metering valve is used to add cleaning and care agents and to rinse the intake system.
Main subassembly II - Heat exchanger with temperature monitor
• The heat exchanger with high-pressure blower burner produces hot water.
• The fuel is supplied via a fuel pump driven by the pump motor.
• The thermostat monitors the working temperature.
• The flow monitor switches the oil burner off in the case of a water shortage.
• The thermal fuse acts as an additional safety element against overheating.
Water quantity, pressure and temperature are steplessly adjustable.
