To select a heat setting, press the corresponding switch(es) to the 'ON' position.

5.3 Adjustable Thermostat

The adjustable thermostat allows you to maintain a desired room temperature:

1. Turn the thermostat knob clockwise to the maximum setting.
2. Once the room reaches your desired temperature, slowly turn the thermostat knob counter-clockwise until the heater switches off.
3. The heater will now cycle on and off automatically to maintain the selected temperature.

The built-in fan can be used to circulate heat more quickly throughout the room:

• Press the fan switch to the 'ON' position to activate the fan.
• The fan can be used independently or in conjunction with the heating elements.

6. Maintenance and Cleaning

Regular cleaning helps maintain the performance and longevity of your heater.

• Always unplug the heater from the power outlet and allow it to cool completely before cleaning.
• Wipe the exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners or solvents.

• The powder-coated fins are designed to resist rust, requiring minimal special care beyond general cleaning.
• Clean the air intake and exhaust vents regularly with a vacuum cleaner to remove dust and lint.

7. Storage

When not in use for extended periods, store the heater in a cool, dry place. It is recommended to cover the heater to protect it from dust.

8. Troubleshooting

If your heater is not operating correctly, please check the following before contacting customer support:

• Heater not turning on: Ensure the power cord is securely plugged into a working outlet. Check if the main power switch and heat setting switches are in the 'ON' position. Verify that the thermostat knob is set to a higher temperature than the current room temperature.
• Heater turns off unexpectedly: This may be due to the Overheat Protection or Tip-Over Safety Switch. Ensure the heater is upright and not obstructed. Unplug the heater, allow it to cool for 30 minutes, then plug it back in and restart.
• Insufficient heating: Ensure the correct heat setting (1000W, 1500W, or 2500W) is selected for your room size. Check that the thermostat is set appropriately. Ensure no objects are blocking the heat output or air vents.

If the problem persists after checking these points, please contact customer support.
