TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR
INJURY TO PERSONS, OBSERVE THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer. If
you have questions, contact the manufacturer at the address or
telephone number listed in the warranty.
2. Before servicing or cleaning unit, switch power off at service panel
and lock service disconnecting means to prevent power from
being switched on accidentally. When the service disconnecting
means cannot be locked, securely fasten a prominent warning
device, such as a tag, to the service panel.
3. Installation work and electrical wiring must be done by qualified
personnel in accordance with all applicable codes and standards,
including fire-rated construction codes and standards.
4. Sufficient air is needed for proper combustion and exhausting of
gases through the flue (chimney) of fuel burning equipment to
prevent backdrafting.Follow the heating equipment manufacturer’s
guidelines and safety standards such as those published by the
National Fire Protection Association (NFPA) and the American
Society for Heating, Refrigeration and Air Conditioning Engineers
(ASHRAE) and the local code authorities.
5. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. Do not use this unit with any solid-state speed control device.
8. To reduce the risk of fire, use only metal ductwork.
9. This unit must be grounded.
10. When applicable local regulations comprise more restrictive
installation and/or certification requirements, the aforementioned
requirements prevail on those of this document and the installer
agrees to conform to these at his own expenses.
TO REDUCETHE RISK OF A RANGETOP GREASE FIRE:
a) Never leave surface units unattended at high settings. Boilovers
cause smoking and greasy spillovers that may ignite. Heat oils
slowly on low or medium settings.
b) Always turn power pack ON when cooking at high heat or when
flambeing food (i.e.: Crêpes Suzette, Cherries Jubilee, Peppercorn
Beef Flambé).
c) Clean ventilating fans frequently. Grease should not be allowed to
accumulate on fan, filters or in exhaust ducts.
d) Use proper pan size. Always use cookware appropriate for the
size of the surface element.
1. For indoor use only.
2. For general ventilating use only. Do not use to exhaust hazardous
or explosive materials and vapors.
3. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off power
unit.
4. Your power pack motor has a thermal overload which will
automatically shut off the motor if it becomes overheated. The
motor will restart when it cools down. If the motor continues to
shut off and restart, have the power pack serviced.
5. The minimum hood distance above cooktop must not be less than
24”. A maximum of 30” above cooktop is recommended for best
capture of cooking impurities.
6. Two installers are recommended because of the large size and
weight of this unit.
7. To reduce the risk of fire and to properly exhaust air, be sure to
duct air outside — Do not exhaust air into spaces within walls or
ceiling or into attics, crawl space or garage.
8. This product is equipped with a thermostat which may start blower
automatically. To reduce the risk of injury and to prevent power
from being switched on accidentally, switch power off at service
panel and lock or tag service panel.
9. Because of the high exhausting capacity of this unit, you should
make sure enough air is entering the house to replace exhausted
air by opening a window close to or in the kitchen.
10. To reduce the risk of fire and electrical shock, the Best CP55IQ
& CP57IQT Series models should only be installed with their own
built-in blowers, and the Best CP57E Series models must only
be installed with Best exterior blower models EB6, EB9, EB12
or EB15; or Best in-line blowers models ILB3, ILB6, ILB9, ILB11.
Other blowers cannot be substituted.
11. Please read specification label on product for further information
and requirements.
12. This power pack is equipped with a RF receiver (optional remote
control sold separately). Changes or modifications not expressly
approved by the party responsible for compliance could void the
user’s authority to operate this product. The remote control has
been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules and the Canadian
ICES-003. These limits are designed to provide reasonable
protection against harmful interference in a residential installation.
The remote control generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of
the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected
WARNING
! CAUTION
TO REDUCE THE RISK OF INJURY TO PERSONS INTHE
EVENT OF A RANGE TOP GREASE FIRE, OBSERVE
THE FOLLOWING*:
1. SMOTHER FLAMES with a close-fitting lid, cookie sheet or metal
tray, then turn off the burner. BE CAREFULTO PREVENT BURNS.
IF THE FLAMES DO NOT GO OUT IMMEDIATELY, EVACUATE
AND CALL THE FIRE DEPARTMENT.
2. NEVER PICK UP A FLAMING PAN — You may be burned.
3. DO NOT USE WATER, including wet dishcloths or towels — This
could cause a violent steam explosion.
4. Use an extinguisher ONLY if:
A. You own a Class ABC extinguisher and you know how to
operate it.
B. The fire is small and contained in the area where it started.
C. The fire department has been called.

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.
