READ AND SAVE THESE INSTRUCTIONS
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 discon-
necting 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 ac-
cordance 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 metal 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.
This appliance is equipped with a cord having a grounding wire with a grounding plug.
The plug must be plugged into an outlet that is properly installed and grounded.
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.
Do not use an extension cord. If the power supply cord is too short, have a qualified
electrician install an outlet near the appliance.

!
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 30" above the cooking surface. See “Install Mounting
Bracket” section for mounting restrictions.
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.
11. Please read specification label on product for further information and requirements.
WARNING
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 flambéing food (i.e. Crepes
Suzette, Cherries Jubilee, Peppercorn Beef Flambé).
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.
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 imme-
diately, 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 - 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 oper-
ate 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 Fire Safety Tips” published by NFPA.

OPERATION
Controls
The hood is operated using the (5) push buttons located on the underside of the
hood. Fig. 1.
Ten Minute Delay
Press Blower Speed 1, Blower Speed 2, or Blower Speed 3 for two seconds when
the blower is running at the selected speed. The LED below the button will start
blinking to display the delay function. After ten minutes the blower will automatically
turn off. If you change the speed while the timer is running, the function will not
deactivate. To deactivate the function, press the button with the blinking LED for two
seconds. Note: The delay is not available for Blower Speed 4.
Filter Alarm
After 30 hours of blower operation, the grease filter alarm is activated and all of the
LED indicators will turn on. The alarm is activated when the motor is off and the
LEDs will remain on for 30 minutes. To deactivate the alarm, press any of the control
buttons for two seconds while the LEDs are on.
After 120 hours of blower operation the charcoal filter alarm is activated and all
of the LED indicators will blink, indicating the charcoal filters need to be replaced.
The alarm is activated when the motor is off and the LEDs will remain on for 30
minutes. To deactivate the alarm, press any of the control buttons for two seconds
while the LEDs are on.
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.
1) If blower is OFF - it turns blower ON to HIGH speed.
2) If blower is ON at a lower speed setting - it turns blower up to HIGH speed.
When the temperature level drops to normal, the blower will return to its original
setting.
WARNING
The HEAT SENTRY™ thermostat can start the blower even if the hood is turned
OFF. When this occurs, it is impossible to turn the blower OFF with its switch.
If you must stop the blower, do it from the main electrical panel.

HALOGEN BULBS
This range hood requires six halogen bulbs (Type T3,
12 Volt, 20 Watt Max, G4 Base).
WARNING: Always switch off the electrical
supply before carrying out any operation on the
appliance.
To change bulbs:
1. Remove the glass lens by removing the (3) mount-
ing screws. Fig. 2.

3. Open the cover by prying from the proper slots. Do
not touch replacement bulbs with bare hands!
4. Replace with Type T3, 12 Volt, 20 Watt Max G4 Base halogen bulbs.
CLEANING AND 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 Filters
The grease filters should be cleaned frequently, typically when the filter alarm turns on. 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 6 months. Replace more often if
your cooking style generates extra grease, such as frying and wok cooking. See “INSTALL
FILTERS” section, on page 15, for removal and installation instructions.
Stainless Steel Cleaning
DO:
• Regularly wash with clean cloth or rag
soaked with warm water and mild soap
or liquid dish detergent.
• Always clean in the direction of original
polish lines.
• Always rinse well with clear water (2 or 3
times) after cleaning. Wipe dry completely.
• You may also use a specialized household
stainless steel cleaner.
DON’T:
•
Use any steel or stainless steel wool or any
other scrapers to remove stubborn dirt.
• Use any harsh or abrasive cleansers.
• Allow dirt to accumulate.
• Let plaster dust or any other construction
residues reach the hood. During construc-
tion/renovation, cover the range hood to
make sure no dust sticks to the stainless
steel surface.
Avoid: When choosing a detergent
• Any cleaners that contain bleach will attack stainless steel
• Any products containing: chloride, fluoride, iodide, bromide will deteriorate surfaces rapidly.
• Any combustible products used for cleaning such as acetone, alcohol, ether, benzol, etc.,
are highly explosive and should never be used close to a range.
