DJUSTING THE AIR FLOW
(1500
UNITS
)
The 1500I-ECM and 1500E-ECM are equipped with ECM motors that can be programmed to maintain various
different airflows. The 1500I-ECM and 1500E-ECM have three selectable speeds (High, Medium, and Low).
Each of these speeds can be further adjusted to obtain the desired airflow. This is done on the ECM circuit
board located within the electrical box.
Both motors contain a separate ECM circuit board to allow for independent adjustment of the motors. The
“adjust” taps will change the airflows on all three of the speeds. Please note that this unit has been factory set
to obtain 1500 cfm at 1” w.g. external static pressure. Adjustment of the high speed settings will produce
higher flows only in situations where the external static pressure is below 1” w.g.
