Page 11 of 20 HEATPRO HEAT PUMP HP13023770 Rev: E NOTICE - When the piping installation is complete, operate the pool filter pump with the heat pump off. Check the entire piping system for leaks. Observe the filter water pressure gauge for abnormalities or obstructions in the filtering system. Failure to follow the instructions may result in property damage. Flow Rate MODEL: HP20654T & HP20654BT This heat pump is designed for minimal water flow of 30 gpm to ensure sufficient heat removal from the condenser, thus avoiding overheating the unit. Flow rates above 75 gpm will begin to create excessive pressure drop through the condenser and require unnecessarily high pumping energy. MODELS: HP20854T & HP20854BT These heat pumps are designed for nominal water flows of 34 gpm through the condenser. A minimum flow of 30 gpm is required to ensure sufficient heat removal from the condenser, thus avoiding overheating the unit. Flow rates above 75 gpm will begin to create excessive pressure drop through the condenser and require unnecessarily high pumping energy. MODELS: HP21104T These heat pumps are designed for nominal water flows of 47 gpm through the condenser. A minimum flow of 30 gpm is required to ensure sufficient heat removal from the condenser, thus avoiding overheating the unit. Flow rates above 75 gpm will begin to create excessive pressure drop through the condenser and require unnecessarily high pumping energy. External Bypass The heat pump is designed for a maximum flow rate of 75 GPM. An External Bypass Assembly can be added to regulate the flow rate through the heat exchanger to prevent damage. Failure to install an External Bypass Assembly with a flow rate of 75 GPM or higher will void the warranty.
