WARNING
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 panel 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 a qualified person(s) 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 separate solid-state speed control device.
8. To reduce the risk of fire, use only steel ductwork.
GROUNDING INSTRUCTIONS
This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk
of electrical shock by providing an escape wire for the electric current.
WARNING - Improper grounding can result in a risk of electric shock.
Consult a qualified electrician if the grounding instructions are not completely understood, or if doubt
exists as to whether the appliance is properly grounded.
TO REDUCE THE RISK OF A RANGE TOP 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 hood ON when cooking at high heat or when flambeing food (i.e. Crepes Suzette,
Cherries Jubilee, Peppercorn Beef Flambe’).
C. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.
D. Use proper pan size. Always use cookware appropriate for the size of the surface element.

!
CAUTION
1. For indoor use only.
2. To reduce risk of fire and to properly exhaust air, be sure to duct air outside. Do not vent exhaust
air into spaces within walls or ceilings or into attics, crawl spaces, or garages.
3. Take care when using cleaning agents or detergents.
4. Avoid using food products that produce flames under the Range Hood.
5. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and
vapors.
6. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray,
construction dust, etc. off power unit.
7. Your hood 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 hood serviced.
8. For best capture of cooking impurities, the bottom of the hood should be a minimum of 24" and a
maximum of 36" above the cooking surface.
9. Two installers are recommended because of the large size and weight of this hood.
10. 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.

The motor is permanently lubricated and never needs oiling. If the motor bearings make
excessive or unusual noise, replace the motor with the exact service motor. The impeller
should also be replaced.
Grease Filter
The grease filters should be cleaned frequently. Use a warm detergent solution. Grease
filter are dishwasher safe.
Clean all-metal filters in the dishwasher using a non-phosphate detergent. Discoloration
of the filter may occur if using phosphate detergents, or as a result of local water
conditions - but this will not affect filter performance. This discoloration is not covered by
the warranty. See “INSTALL FILTERS” section for removal and installation instructions.
Non-ducted Recirculation Filter
The non-ducted recirculation filter should be changed every 6 months. Replace more
often if your cooking style generates extra grease, such as frying and wok cooking. See

OPERATION
Controls (Fig.1)
The hood is operated using the (5) push buttons located on the front edge of the hood. The
Light On/Off buttons turn the lights on and off.
The Blower Off / - button decreases the blower speed each time pressed. Depress and
hold the button for 2 seconds to turn the blower off.
The Blower On /+ button turns the blower on and increases the blower speed each time
pressed. There are four different speed settings: Low, Medium-Low, Medium-High and High.
The Blower LED Indicators illuminate to indicate the selected blower speed.
The Delay button activates the delay-off feature. When the blower in on and the button is
pushed, the blower will continue to operate at the current speed setting for 10-minutes
before automatically turning itself off. The LED (on the right) flashes during operation.
The LED (on the right) is also used as a filter clean reminder. It will flash after 30 hours of
operation - indicating the need to clean the filters.
The Filter Clean Reset button is used to reset the 30-hour filter timer. After filters are
cleaned or replaced, press button once to reset the filter clean alarm.
HEAT SENTRY™
Your hood is equipped with a HEAT SENTRY™ thermostat. This thermostat is a device that
will turn on or speed up the blower if it senses excessive heat above the cooking surface.

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.
