Additional Information:
*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.
Magna GEO + UPS26-99 (high speed)
Magna GEO (lowest duty cycle -- highest flow/head)
Magna GEO (highest duty cycle -- lowest flow/head)
