ATTENTION

: Portable electric heaters are designed for spot heating, or as a 

supplementary heat source. They are not intended to be main sources of heat during 

the normal heating season.There may be trace of smoke or odour when unit is first 

operated. Do not be alarmed. This indicates that a drop of oil fell on the heating coil 

during the manufacturing process. It will quickly evaporate and should not re-occur.
