FAN POWERED TERMINAL UNITS • 35S SERIES
NOTES:
• The ECM is pressure independent and
constant volume in operation at factory
or field set point within the shaded area.
Airflow does not vary with changing
static pressure conditions. The motor
compensates for any changes in external
static pressure or induced air conditions
such as filter loading.
• Airflow can be set to operate on
horizontal performance line at any point
within shaded area using the solid state
volume controller provided.
• Fan curves shown are applicable to 120,
208, 240 and 277 volt, single phase
ECM's. ECM's, although DC in operation,
include a built-in AC/DC converter.
Electrical Data
*
The EPIC ECM is a variable horsepower motor.
Refer to Selectworks schedule for actual power
consumption.
FLA = Full load amperage.
All motors are single phase/60 Hz.
