4. Operating Instructions
Once the heater is securely installed and connected to power, follow these steps to operate it:
- Start Your Vehicle: For optimal performance and to avoid draining your vehicle's battery, it is recommended to operate the heater while the engine is running.
- Turn On the Heater: Locate the power switch on the heater (typically a red rocker switch) and flip it to the 'ON' position.
- Adjust Airflow: The heater provides warm air quickly, often within 30 seconds. Direct the airflow towards the desired area, such as the windshield for defrosting or the cabin for general heating. The unit features two air outlets for even heat distribution.
- Defrosting: For defrosting windows, position the heater to blow warm air directly onto the icy or foggy glass. The precise temperature control helps melt snow and ice efficiently.
- Turn Off: When you no longer need heating, flip the power switch to the 'OFF' position and unplug the unit from the 12V socket.
