1. Safety Precautions

⚠️ WARNING

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless supervised by a responsible person.
Children should be supervised to ensure they do not play with the appliance.
Do not cover the heater — overheating hazard.
If the supply cord is damaged, it must be replaced by the manufacturer or qualified service agent.
The heater must not be located immediately below a socket outlet.
Do not share the same socket with other appliances to avoid current overload.
Pull the plug when powering off. Do not pull wires by hand.
Stop power immediately if heater fails or wires are damaged. Do not repair yourself — contact authorized service.
The heater must be installed at least 2.2 m above ground level.
Keep ≥ 150 mm clearance behind the heater; ≥ 1000 mm in front; ≥ 200 mm on each side.
Cut off power and allow surface to cool before cleaning. Do not flush with water.
Do not install in areas with flammable, explosive materials or risk of electric shock.
Do not insert metal or foreign objects into the heater.
Panel surface temperature can exceed 50 °C to 386 °C — do not touch.
Do not splash water onto the heater.

2. Infrared Heater Theory

Far-infrared radiant heaters use a specially coated aluminum panel. The heat generated by the heating element is transferred radiantly to people and objects with maximum efficiency — absorbed by walls, floors, and furniture, just like sunshine. Unlike convection heaters, infrared heating does not circulate air, so dust and particles remain settled, keeping the air clean, fresh, and comfortable.
