*UPS26-99 is a constant speed pump; Magna GEO is a variable
speed pump. When both pumps are running, the Magna GEO
operates between duty cycles shown below to maintain
set flow rate or temperature difference.

Mounting
Flow Center is designed for indoor
installation only.
Flow Center must be installed with
the pump's motor shaft horizontal.
Do not install flow center with the
pump's motor shaft vertical.
The terminal box should be located in
one of the following orientations:
