Operating Instructions
The heater is equipped with a thermostat control and a fan delay feature for efficient heating.
- Power On: Ensure the heater is securely plugged into the appropriate 240V, 20A outlet.
- Set Thermostat: Use the thermostat dial on the unit to set the desired temperature. Turn the dial clockwise to increase the heat setting. The heater will cycle on and off to maintain the set temperature.
- Fan Delay: The fan delay feature allows the fan to continue running for a short period after the heating element shuts off. This utilizes residual heat and helps distribute warmth more evenly.
- Overheat Protection: In case of overheating, the heater will automatically shut off. If this occurs, turn off the heater, unplug it, and allow it to cool down before restarting. Inspect for any obstructions to airflow.
