Curves are manufacturer’s reported averages using water at 68°F [20°C].
Flow center is
designed for indoor
installation only.
Flow center must
be installed in an
upright position as
shown to the right.
The pump terminal
box should be
located in one of the
following orienta-
tions:
Motor: 208-230V, 50/60 Hz, single phase, 2-pole, ETL
C/US
approved (meets UL and CSA
requirements), electronically protected, insulation class F, 0.09 to 1.7 Amps (at 230V)

NOTES: The Magna GEO
(variable speed) pump
adjusts speed (when used
with controller) to maintain
flow rate or temperature
difference. For Watts based
upon a specific flow rate and
pressure drop, go to
www.geo-flo.com, and use
the pump sizing calculator.
