19. CALIBRATE IQ BLOWER SYSTEM™ (CP55IQ & CP57IQT SERIES ONLY)
NOTE: Calibration is for ducted installations only. Do not calibrate non-ducted installations.
After the power pack 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 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:
A. 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.
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, use of flex ducting and/or crushed ducting.
Three options are available if your power pack system has too much restriction:
1. Accept airflow as is. Press the calibration button to accept airflow as is. The IQ Blower System™ is now configured to its 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 power pack to default factory settings and achieve standard high pressure blower performance 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.

18. REINSTALL HYBRID BAFFLE FILTERS
CAUTION
Remove protective plastic film covering hybrid baffle filters before installing them.
It is recommended to install side filters first and finish with center one(s).
1. Insert one end of hybrid baffle filter into the front
