5. Setup and Installation

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

  1. Placement: Choose a stable, level outdoor location near your pool, ensuring at least 2 feet of clear space around the unit for proper airflow.
  2. Connectors: Attach the provided pipe connectors to the water inlet and outlet ports on the heat pump. Ensure a tight seal using thread seal tape if necessary.
  3. Hose Connections: Connect the water hoses from your pool's filter pump system to the heat pump. The water flow should be from the filter pump, into the heat pump's water inlet, and then from the heat pump's water outlet back to the pool. Secure hoses with clamps.
  4. Electrical Connection: Plug the heat pump into a dedicated 110V 60Hz grounded electrical outlet. No additional wiring is required.
  5. Initial Check: Once all connections are made, turn on your pool's filter pump to ensure water flow through the heat pump. Check for any leaks.
