The heat pump integrates with your existing pool filtration system. The recommended water flow rate for optimal performance is 3000-4000 GPH. A ball valve may be required to regulate the flow depending on your pump's output.

• Connect the heat pump in line after your pool filter and before the water returns to the pool.
• Ensure all connections are secure and watertight.
• Note: Adapters such as 1.25" & 1.5" hose adapters, 1.5-inch PVC adapters, and 40mm to 1.5" hose adapters are typically not included and may be required for your specific setup.
