CALIBRATE IQ BLOWER SYSTEM
TM
INTERNAL BLOWER DUCTED UNITS ONLY
After the hood is installed and wired, engage the calibration process (our Guaranteed Performance
System Technology to ensure full-rated airflow is being delivered). Prior to calibration, ensure that all
filters, light bulbs and duct system are installed.
CALIBRATION PROCESS
Hold the calibration button for 3 seconds; calibration button will light up and stay on for up to 13 minutes.
The blower will start and begin the calibration process. When calibration is complete, one of two things
will occur:
1. The blower turns off and calibration button light stays on = Successful calibration. Press the button
to turn off the LED. Note: The LED will also turn off if you select any blower speed on the control.
2. The blower turns off and calibration button light blinks continuously = Too much restriction in the
ductwork is preventing the IQ Blower System™ from achieving the rated airflow. The blower is
automatically set to maximum intensity.
NOTE: Common items that cause restrictions: restricted damper flap (backdraft damper, wall cap,
roof cap), too many elbows, duct size less than 80% of hood outlet, poor transition, use of flex ducting
and/or crushed ducting.
Three options are available if your hood system has too much restriction:
1. Accept airflow as is.
a. Press the calibration button to accept airflow as is. The IQ Blower System™ is nowconfigured to
the highest possible performance. The blinking calibration light goes out. Note: The LED will also
turn off if you select any blower speed on the control.
2. Correct duct restriction, clear the original calibration data, and repeat the calibration process.
a. Correct the duct restriction.
b. Clear the original calibration data by holding calibration button for 10 seconds. The light will blink
3 times to confirm and the blower configuration will go back to default settings.
c. Repeat calibration process from the beginning.
3. Clear calibration data to reset hood to default factory setting and achieve standard high
pressure blower performance.
a. Clear calibration data and reset hood to factory default setting by holding calibration
button for 10 seconds. The light will blink 3 times to confirm and the blower configuration
will go back to default settings.
