3.  Appliance description

The appliance is a wall mounted electric direct heater.
The appliance is suitable as a full heating system in bathrooms, 

for example, or for use between seasons and as a booster heater 

in smaller rooms, such as hobby and guest rooms.
The air in the appliance is heated by a heating element and ex-

pelled via natural convection through the air outlet grille at the 

top. Cool room air flows in through the apertures at the bottom 

of the appliance.
After mounting the appliance on the wall and making the electri-

cal connection using a permanent power supply via an appliance 

socket, the appliance is ready for operation.
