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 the 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 a
qualified person(s) in accordance with all applicable codes
and standards, including fire-rated construction.

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 guideline and safety standards such as those
published by the National Fire Protection Association (NFPA),
and the American Society of Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE), and the local code au­thorities.

5. This product may have sharp edges. Be careful to avoid cuts
and abrasions during installation and cleaning.

6. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.

7. Ducted fans must always be vented to the outdoors.

8. Use only metal ductwork.

9. Do not use this fan with any solid-state speed control device.

10. As an alternative, this product may be installed with the UL­approved cord kit designated for the product, following in­structions packed with the cord kit.

11. This unit must be grounded.

TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:

1. 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.

2. Always turn hood ON when cooking at high heat or when
flambéing food (i.e. Crepes Suzette, Cherries Jubilee, Pep­percorn Beef Flambé).

3. Clean ventilating fans frequently. Grease should not be al­lowed to accumulate on fan or filter.

4. Use proper pan size. Always use cookware appropriate for
the size of the surface element.

TO REDUCE THE RISK OF INJURY TO PERSONS IN THE
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 CAREFUL TO
PREVENT BURNS. If the flames do not go out immediately,
EVACUATE AND CALL THE FIRE DEPARTMENT.

WARNING

2. NEVER PICK UP A FLAMING PAN — You may be burned or
spread the fire.

3. DO NOT USE WATER, including wet dishcloths or towels - a
violent steam explosion will result.

4. Use an extinguisher ONLY if:

A. You know you have a Class ABC extinguisher, and you

already know how to operate it.
B. The fire is small and contained in the area where it started.
C. The fire department is being called.
D. You can fight the fire with your back to an exit.

* Based on “Kitchen Firesafety Tips” published by NFPA.

CAUTION

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 impeller, keep drywall spray, construction dust, etc.,
off power unit.

4. Do not use over cooking equipment greater than 60,000
BTU/hr.

5. 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.

6. A maximum height of 24” above the cooktop is recommend­ed for best capture of cooking impurities. The bottom of the
hood MUST NOT BE LESS than 18” above the cooktop.

7. Please read specification label on product for further infor­mation and requirements.

NOTE If hood is to be installed non-ducted:

Purchase non-ducted filter (Model BPQTF) from your
local distributor or retailer.

Installer: Leave this manual

with the homeowner.

Homeowner: Cleaning, Maintenance and

Operating instructions on page 2.

OPERATION

Always turn the hood ON before cooking in order to establish an
air flow in the kitchen. After turning off the range, let the hood run
for a few minutes to clear the air.

This range hood is equipped with the latest in capacitive touch
technology. The buttons do not move, but are touch sensitive.
When a touch is understood, the control will emit a sound.

1. Touch any button to “wake up” the control.

FAN

2. Touch fan button to turn fan on to low speed.

3. Touch fan button again for medium speed, high
speed, and fan off.

The graduations under the fan icon in the LCD screen

will illuminate to indicate the current fan speed setting.

LIGHT

2. Touch light button to turn light on to dim setting.

3. Touch light button again for medium, bright, and
light off.

The graduations under the light icon in the LCD

screen will illuminate to indicate the current light
intensity setting.

DELAY OFF

This feature allows the fan to run for 10 minutes, then
automatically shut the fan off. Use this feature to clear
the air after you are finished cooking.

1. While fan is operating, touch the delay off button.
The button will flash while the delay off feature is
active.

FILTER CLEAN

The filter clean reminder will flash when it is time to
clean or replace the filter, based on your individual
use pattern.

To reset filter clean reminder indicator, touch and hold
button for three seconds.

HEAT SENTRY

The heat sentry continuously monitors temperature and will
automatically turn the fan on to high speed when the temperature
is above normal.

The fan button will flash while heat sentry is active.
After the temperature returns to normal, the heat sentry will return

the fan to it’s previous setting.

LIGHT BULBS

The light bulbs included with this hood are the latest in LED
cooktop illumination technology - offering bright lighting and
lasting up to 10 times as long as a normal bulb. While they are
available as service parts, these bulbs are designed to last the
life of the hood.

CLEANING & MAINTENANCE

Proper maintenance of the Range Hood will assure proper
performance of the unit.

Motor

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 filter should be cleaned frequently. Use a warm
dishwashing detergent solution. Grease filter is 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 3-6
months. Replace more often if your cooking style generates extra
grease, such as frying and wok cooking.

3 Choose a straight, short duct run to allow the hood to

perform most efficiently. Long duct runs, elbows and
transitions will reduce the performance of the hood. Use
as few of them as possible. Larger ductwork may be
required for best performance with longer duct runs.

4 Install wall cap or roof cap. Connect metal ductwork to

cap and work back towards the hood location. Use duct
tape to seal the joints between ductwork sections.
