3. Setup Instructions
- Unpacking: Carefully remove the heater from its packaging. Retain packaging materials for future storage or transport.
- Placement: Place the heater on a stable, flat, and heat-resistant surface. Ensure there is at least 1 meter (3 feet) of clear space around the heater from any walls, furniture, curtains, or other combustible materials. Do not place it directly under a power outlet.
- Power Connection: Unwind the power cord completely. Insert the power plug firmly into a standard AC100V 50/60Hz wall outlet. Do not use extension cords or power strips with this appliance.
- Initial Use: During the first few hours of operation, a slight odor may be noticeable. This is normal and will dissipate quickly. Ensure the room is well-ventilated during initial use.
4. Operating Instructions
- Power On: Plug the heater into a suitable power outlet.
- Adjusting Temperature: Rotate the temperature control knob (usually located on the front or top of the unit) clockwise to increase the heat setting and counter-clockwise to decrease it. Start with a lower setting and adjust as needed for comfort. The heater will cycle on and off to maintain the selected temperature.
- Power Off: To turn off the heater, rotate the temperature control knob to the minimum setting or the "OFF" position, then unplug the unit from the wall outlet.
- Safety Features: The heater is equipped with a tip-over switch that automatically turns off the unit if it is accidentally knocked over. It also has overheat protection that shuts off the heater if it gets too hot. If either of these safety features activates, unplug the heater and allow it to cool down before attempting to restart.
5. Maintenance
