4. Setup & Installation
Proper installation is crucial for the efficient and safe operation of your heat pump. It is recommended that installation be performed by a qualified professional.
4.1 Site Selection
- Location: Place the heat pump on a stable, level surface, preferably concrete or a reinforced pad, near the pool.
- Clearance: Ensure adequate clearance around the unit for proper airflow. Refer to Figure 3.2.5 for airflow direction. Maintain at least 50 cm (20 inches) from any walls or obstructions on the intake sides and sufficient vertical clearance for exhaust.
- Drainage: Position the unit where condensate water can drain away freely without causing damage or creating slip hazards.
4.2 Plumbing Connections
- Connect the heat pump to your pool's filtration system after the filter and before any chemical feeders.
- Use appropriate plumbing fittings (e.g., 32/38mm connectors) to ensure a watertight seal.
- Install bypass valves to allow for isolation of the heat pump for maintenance without interrupting pool circulation.
4.3 Electrical Connections
- The heat pump requires a dedicated electrical circuit with appropriate voltage and amperage. Consult the specifications section for details.
- Ensure the power supply is equipped with a Residual Current Device (RCD) or Ground Fault Circuit Interrupter (GFCI) for safety.
- All electrical connections must comply with local electrical codes.
4.4 Initial Startup
- After plumbing and electrical connections are complete, ensure the pool pump is running and water is flowing through the heat pump.
- Turn on the electrical power to the heat pump.
- Follow the on-screen prompts on the digital display or use the mobile app to configure initial settings.
