- Power/Mode Selection: Locate the control knob on the front panel. Turn the knob to select your desired heating mode:
- OFF: Turns the heater off.
- LOW (600W Radiant): Activates the radiant heating element only, providing gentle, direct heat.
- MED (900W Fan Forced): Activates the fan-forced heating element, circulating warm air.
- HIGH (1500W Radiant & Fan Forced): Activates both radiant and fan-forced elements for maximum heat output.
- Thermostat Adjustment: Use the thermostat dial to set the desired room temperature. Turn the dial clockwise for a higher temperature setting and counter-clockwise for a lower setting. The heater will cycle on and off to maintain the set temperature.
- Initial Operation: When first turned on, a slight odor may be present. This is normal and will dissipate after a few minutes of operation.
Maintenance
Regular maintenance ensures optimal performance and longevity of your heater. Always unplug the heater and allow it to cool completely before performing any maintenance.
- Cleaning:
- Wipe the exterior surfaces with a damp cloth.
- Do not use harsh chemical-based cleaners, abrasive pads, or scouring powders, as these can damage the finish.
- Remove loose dust from the grilles and interior components using a feather duster or a vacuum cleaner with a brush attachment.
- Storage: If storing the heater for an extended period, clean it thoroughly and store it in a cool, dry place, preferably in its original packaging.
Troubleshooting
If your heater is not operating correctly, consult the following table for common issues and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
