Curves are manufacturer’s reported averages using water at 68°F [20°C].
Flow center is
designed for indoor
installaon only.
Flow center must
be installed in an
upright posion as
shown to the right.
The pump terminal
box should be
located in one of the
following orienta-

Motor: 208-230V, 50/60 Hz, single phase, 2-pole, ETL
C/US
approved (meets UL and CSA
requirements), electronically protected, insulaon 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
ow rate or temperature
dierence. For Was based
upon a specic ow rate and
pressure drop, go to
www.geo-o.com, and use
the pump sizing calculator.
