Multiple Heat Pump Connections, To Pool

Multiple Heat Pump Connections

All plumbing on multiple heat pump installations must be done in parallel see Figures 9 and 10. An equal flow of water to each heat pump is important for optimum operation.

NOTE: It may be necessary to adjust water pressure switch if a unit is installed below the water level. See page 20 for details on when and how to adjust the pressure switch.

Each heat pump allows a maximum flow rate of 125 gpm and requires a minimum of 30 gpm.
