5. Maintenance
Regular maintenance ensures the longevity and efficiency of your heater.
- Keep the area around the heater clear of debris, leaves, and other obstructions to ensure proper airflow.
- Periodically inspect all plumbing and electrical connections for any signs of wear or damage.
- Ensure your pool's filtration system is clean and operating correctly to maintain optimal water flow through the heater.
6. Troubleshooting
6.1. Heater Not Heating / Error Codes
If the heater is not heating or displays an error code (e.g., E03), the most common cause is insufficient water flow. The heater is designed with safety mechanisms that prevent it from operating if the water pump/filter is not running or if the flow rate is too low. Always ensure your pool's circulation pump is active when the heater is in use.
- Check that the circulation pump is turned on and functioning correctly.
- Inspect the pool filter for cleanliness and ensure it is not clogged.
- Verify that all valves in the plumbing system are open and allowing proper water flow to the heater.
If the issue persists after checking these points, consult a qualified technician.
