14. Lower half of housing

The transportable low-sulphur heating-oil or diesel driven hot air generator is ideal for heating and drying well ventilated rooms in industry, agriculture, construction and recreation (camping) The appliance is to be used only for its prescribed purpose. Any other use is deemed to be a case of misuse. The user/operator and not the manufacturer will be liable for any damage or injuries caused as a result thereof. Please note that our appliance has not been designed for use in commercial, trade or industrial applications. Consequently, our warranty will be voided if the appliance is used in commercial, trade or industrial applications or for other equivalent activities.

4. Mode of operation

The hot air generator is equipped with a compressor, for suction of fuel out of the tank by creating a vacuum. The suctioned fuel is directed to a blowpipe nozzle. At the nozzle, a mixture of air and fuel is created. The air and fuel mixture is ignited electrically in the combustion chamber. The fan blows air into the combustion chamber, which, after being heated, gets blown out at the front. The thermostat knob can be adjusted to create the right temperature. After this temperature has been reached the appliance is automatically switched off, and if the temperature should drop again, it is automatically switched back on. A photo cell permanently monitors the combustion process and turns the appliance on or off if there are irregularities. If overheating occurs, the appliance will also switch off. If this is the case, please contact customer service. The electrical components are protected by a miniature fuse (fusible insert). If there is a fault in the miniature fuse, please contact customer service.
