1. Power On/Off: Press the Power button () to turn the heater on or off. The red indicator light will illuminate when the unit is powered on.
2. Select Heat Setting: Use the SET button to cycle through heat settings: LO (Low), HI (High), or specific temperatures (65°, 70°, 75°, 80°F). The selected setting will be displayed.
3. Set Desired Temperature (EnergySmart Thermostat Mode): When a specific temperature (65°, 70°, 75°, 80°F) is selected, the heater will operate in EnergySmart Thermostat mode. It will cycle on and off to maintain the set temperature, optimizing energy usage. The display shows the current room temperature and the set temperature.
4. Set Timer: Press the Timer button () to set the auto-off timer. You can select intervals from 2 to 12 hours. The heater will automatically shut off after the set time.
5. Energy Usage Indicator: The EnergySmart indicator lights will show the current energy consumption (Low, Medium, High) based on the heater's operation.

Note: Oil-filled radiator heaters take time to heat up the internal oil and then radiate heat into the room. Allow approximately 30 minutes for the unit to reach its full operating temperature and begin effectively warming the space.

Maintenance

Regular maintenance ensures optimal performance and longevity of your heater.

• Cleaning: Always unplug the heater before cleaning. Use a soft, damp cloth to wipe the exterior surfaces. Do not use abrasive cleaners or solvents. Ensure no water enters the interior of the heater.
• Dust Removal: Periodically use a vacuum cleaner with a brush attachment to remove dust from the grilles and fins.
• Storage: When not in use, store the heater in a cool, dry location. You can use the integrated cord wrap for neat storage of the power cord.
• No Internal Maintenance: The oil in this heater is permanently sealed and never needs refilling. Do not attempt to open the heater or perform any internal maintenance.

Troubleshooting

If your heater is not operating correctly, consult the following common issues:

• Heater does not turn on:
  • Ensure the power cord is securely plugged into a working 120V outlet.
  • Check if the household circuit breaker has tripped.
  • Verify the power button is pressed and a heat setting is selected.
• Heater turns off unexpectedly:
  • The Tip-Over Switch may have been activated. Ensure the heater is on a stable, level surface.
  • The Overheat Protection may have been activated. This occurs if the heater becomes too hot. Unplug the unit, allow it to cool for 30 minutes, and ensure there are no obstructions blocking the air intake or exhaust grilles.
  • The timer may have reached its set duration.
• Heater is not heating the room sufficiently:
  • Ensure the desired temperature setting is higher than the current room temperature.
  • Check that the heater is on the High heat setting if maximum warmth is desired.
  • Verify that the room size is within the recommended heating coverage (up to 250-300 sq ft).
  • Ensure doors and windows are closed to prevent heat loss.
