Important safety instructions: 

 

Only use the recommended voltage for operating the unit ! 

The heater is not suitable for use outdoors or in other wet or damp environments ! 

Please note that the heater can become very hot during operation, so keep a sufficient distance from 
flammable or easily combustible objects at all times ! 

Do not place the heater directly next to a power socket ! 

Do not use a timer or automatic on/off switch in conjunction with this heater ! 

Never use the heater on moving surfaces, objects or vehicles ! There is a risk that the heater may tip over.  

It is recommended to use a separate power source (socket) only for the supply of the heater. (Please do not 
use multiple sockets to operate the heater) ! 
Furthermore, please ensure that the power cable is always laid with sufficient distance to the heat source. 

Supervise the heater when children are near the appliance ! 

Be aware of electricity, never walk into or insert objects into the appliance ! Never reach near the plug or socket 
with wet hands ! 
Never touch the heater or the power cables with wet hands! 

Do not place any objects on the heater ! 

Do not block the supply and/or exhaust air of the unit and please ensure sufficient space/clearance around the 
unit ! 

Ensure that there is sufficient air supply to the unit, otherwise it can lead to a reduction in performance and, in 
the worst case, to overheating and/or fire ! 

Only qualified personnel or electricians are allowed to open the unit ! 

Make sure that no moisture gets into or onto the unit ! 

Make sure that the power cable is completely unfolded before connecting it to the socket ! 

Make sure that the plug is cleanly and properly connected to the socket before using the appliance ! 

Make sure that highly flammable substances (e.g. gases/oils etc.) are never in the vicinity of the unit ! 

If the connecting cable of this appliance is damaged, it must be replaced by the manufacturer or its after-sales 
service or a similarly qualified person in order to avoid hazards. 

This appliance is not intended to be used by persons (including children) with reduced physical, sensory or 
mental capabilities, or lack of experience and/or knowledge, unless they have been given supervision or 
instruction concerning use of the appliance by a person responsible for their safety. 

If you are not going to use the unit for a long time, switch it off and disconnect the mains plug ! 

 
Please switch off the unit immediately and disconnect it from the mains/power supply if anything 
seems to be wrong !!! In this case, please contact a specialist and do not try to repair the unit 
yourself !!! 

 

Example: 

Fan does not run during operation, you notice sparks or the fuse has blown.
