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 and the duct system are
installed.
CALIBRATION PROCESS Fig. 21.
Open the bottom panel. Hold the calibration
button for 3 seconds and the calibration
button will light up. Close the bottom
panel. The blower will start and begin
the calibration process - which will take
approximately 13 minutes. When calibration
is complete, one of two things will occur:
A. The blower turns off and calibration
button light turns off = Successful
calibration.
B. 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,

2. Correct duct restriction and repeat the
calibration process.
a. To clear the original calibration data,
hold calibration button for 10 seconds.
The light will blink 3 times to confirm
and the blower configuration will go
