5.1 Power On/Off
- To Power On: Plug the heater into a power outlet. The thermostat display will illuminate.

5.2 Setting the Temperature
The NCU-2Te digital thermostat allows you to set your desired room temperature:

5.3 Convection Heating Principle
This heater operates on the principle of natural convection. Cold air enters the bottom of the unit, is heated by the internal element, and rises out through the top vents, circulating warmth throughout the room without the need for a fan. This results in silent operation and even heat distribution.
6. Maintenance
The NOBO NTL4N 20 heater is designed for minimal maintenance. Regular cleaning will help ensure optimal performance and longevity.
- Cleaning: Before cleaning, always unplug the heater and allow it to cool completely. Wipe the exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Dust Removal: Periodically vacuum the air intake and exhaust vents to remove any accumulated dust.
- Storage: If storing the heater for an extended period, ensure it is clean and dry. Store it in a cool, dry place, preferably in its original packaging.
