- Air Intake/Outlet: Ensure the air intake and outlet grilles are free from dust and obstructions to maintain efficient airflow.
Troubleshooting
If your heater is not operating correctly, consult the following common issues before contacting support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater does not turn on. | No power supply; tripped circuit breaker; safety cut-out activated. | Check power connection and circuit breaker. Allow unit to cool for 30 minutes, then try resetting the safety cut-outs (if accessible and safe to do so, consult a professional). |
