4. Setup & Installation
4.1 Unpacking and Inspection
- Carefully remove the heat pump from its packaging.
- Inspect the unit for any signs of shipping damage. Contact your retailer immediately if damage is found.
- Ensure all components listed in the packing list are present.
4.2 Placement
- Place the heat pump on a solid, level surface, preferably concrete or a sturdy pad.
- Ensure there is at least 20 inches (50 cm) of clear space around the air intake and exhaust sides for optimal airflow.
- Position the unit as close as possible to the pool and filtration system to minimize plumbing runs.
4.3 Water Connection
The heat pump must be connected to your pool's existing filtration system. Water flows from the pool pump, through the filter, then through the heat pump, and finally back to the pool.
- Turn off the pool pump and close any necessary valves.
- Connect the pool water outlet (after the filter) to the heat pump's 'Water In' port.
- Connect the heat pump's 'Water Out' port to the pool return line.
- Use appropriate PVC fittings and sealant to ensure watertight connections.
