5. Setup
Follow these steps to prepare your radiator for use:
- Attach the Wheels: Carefully turn the radiator upside down. Attach the four wheels to the designated slots at the bottom of the unit. Ensure they are securely fastened.
- Position the Radiator: Place the radiator upright on a stable, level surface. Ensure there is adequate clearance around the unit (at least 50 cm from walls, furniture, and curtains) to allow for proper heat circulation and prevent fire hazards.
- Plug In: Insert the power plug into a suitable grounded electrical outlet. Ensure the outlet is rated for the heater's power consumption (2000W).
6. Operating Instructions
6.1. Power On/Off
- To turn on the radiator, rotate the 3-stage power switch to one of the power settings (I, II, or III). The power indicator light will illuminate.
- To turn off the radiator, rotate the 3-stage power switch to the '0' (off) position. The power indicator light will turn off.
6.2. Temperature Control (Thermostat)
- The stepless thermostat allows you to set your desired room temperature.
- Rotate the thermostat dial clockwise to increase the temperature setting and counter-clockwise to decrease it.
- The radiator will cycle on and off to maintain the set temperature, optimizing energy consumption.
6.3. Power Level Selection
The 3-stage power switch offers different heating outputs:
- Setting I: Low heat output (e.g., 800W) for gentle heating or maintaining temperature.
- Setting II: Medium heat output (e.g., 1200W) for moderate heating.
- Setting III: High heat output (2000W) for rapid heating of larger spaces.
Select the appropriate power level based on your heating needs and room size.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your radiator.
- Cleaning: Always unplug the radiator and allow it to cool completely before cleaning. Wipe the exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners or solvents. Do not immerse the radiator in water.
- Storage: If storing the radiator for an extended period, ensure it is clean and dry. Store it in a cool, dry place, preferably in its original packaging, to protect it from dust and damage.
8. Troubleshooting
Refer to the table below for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Radiator does not turn on. | No power supply; Power switch is off; Overheating protection activated; Anti-tip switch activated. | Check power outlet and plug; Turn power switch to I, II, or III; Unplug and let cool for 30 minutes; Ensure radiator is upright on a flat surface. |
| Radiator is on but not heating. | Thermostat set too low; Room temperature already reached. | Increase thermostat setting; The radiator will cycle on when the room temperature drops below the set point. |
| Radiator makes unusual noises. | Normal expansion/contraction of metal during heating/cooling. | This is normal and not a fault. If noises are excessive or unusual, contact support. |
| Radiator smells burnt. | Dust accumulation on heating elements; New unit burning off manufacturing residues. | Unplug and clean thoroughly; Initial smell is normal for new units and should dissipate after a few hours of use. Ensure good ventilation. |
