4. Setup and Installation
Proper installation is crucial for the performance and longevity of your heat pump. Follow these steps carefully:

- Electrical Connection: Connect the heat pump to a dedicated, grounded electrical circuit as per local electrical codes. Consult a qualified electrician if you are unsure. Do not use extension cords or adapters.
- Initial Water Flow: Before powering on, ensure the pool pump is running and water is flowing through the heat pump. Check for any leaks.
