5.9.2 Bypass Flow Piping Method

A bypass flow system is recommended under one or more of the following conditions:
•
If the total system flow is greater than the amount required by the indirect heat exchanger.
•
If pool or spa water system exceeds 95°F in temperature, a bypass flow configuration is
used to cool down the return flow in order to prevent tripping the high limit switch and to
prevent water with temperatures over 115°F from entering the pool or spa system.
•
Multiple unit installations.
An example of the configuration and necessary components for a bypass flow system are shown
in Figure 5-5b.
