OPERATING INSTRUCTIONS (CONTINUED)
OPTIMAL OPERATING CONDITIONS 
To get the most out of your Soleus Air Micathermic heater, follow these helpful hints: 
 
1. All electric heaters are limited to maximum of 1500 watts (per UL and ETL requirements). Due to this 
limitation all electric heaters can heat approximately 150 square feet. Micathermic heaters fit in this 
category, but they are able to provide a more comfortable and consistent heat than other heating 
technologies. 
2. For optimal performance, place the heater in a room and close all windows and doors. This will confine the
heat to the area that needs it most.
3. To save energy and in turn save money in the winter, place the heater in a room or area that needs extra
heat instead of raising the thermostat on your central heating system. This heater will function very well as 
an additional heating source and can easily maintain the temperature in most rooms and attached 
bathrooms. There is no need to increase the heat in the entire house when you only need comfort in the 
room in which you are currently located. 
Overheat Safety Protection
The heater comes equipped with over-
heat safety protection, so it can detect if 
it is overheating and will automatically 
shut off. When the unit temperature 
falls again, power will be resumed. To 
avoid overheating and potential risk of 
fire, DO NOT cover the heater.
