Flow Center is designed for
indoor installaon only.
Flow Center must be installed with
the pump’s motor sha horizontal.
Do not install ow center with the
pump’s motor sha vercal.
The terminal box should be located in
one of the following orientaons:

NOTES: The Magna GEO (vari-
able speed) pump adjusts speed
(when used with controller) to
maintain ow rate or tem-
perature dierence. For Was
based upon a specic ow rate
and pressure drop, go to www.
