!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 flambeing food
(i.e.: Crêpes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).
c) Clean ventilating fan 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.
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.
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.
D. You can fight the fire with your back to an exit.
* Based on “Kitchen Fire Safety Tips” published by NFPA.
!CAUTION
• For indoor use only.
• For general ventilating use only. Do not use to exhaust hazardous or explosive materials
and vapors.
• To avoid motor bearing damage and noisy and/or unbalanced fan blade, keep drywall
spray, construction dust, etc. off range hood.
• 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.
• For best capture of cooking fumes, the bottom of the hood MUST NOT BE LESS than 18”
and at a maximum of 24” above the cooking surface.
• Always follows the cooking equipment manufacturer’s requirements regarding the
ventilation needs.
• 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.
• When installing, servicing or cleaning the unit, it is recommended to wear safety glasses
and gloves.
• Please read specification label on product for further information and requirements.

INSTALLATION MANUAL
OPERATION

Operation
Always turn your hood on before you begin cooking to establish an air flow in the kitchen.
Let the blower run for a few minutes to clear the air after you turn off the range.This will help keep
the whole kitchen cleaner and fresher.
The LED modules included with these hoods are the latest in LED cooktop illumination technology
specially esigned to operate in the elevated temperatures of cooking - offering bright lighting and
lasting up to 25 times as long as a standard bulb and greater reliability than typical replacement LED bulbs.
Operate the hood as follows:
FILTER CLEANING REMINDER
When it is time to clean the hood and filters (refer to Cleaning and Maintenance on page 6), the
3 blower button LED indicators will flash slowly for 30 seconds after turning the blower OFF.This will
happen every time the blower is turned OFF until the filter cleaning reminder has been reset. Once
the cleaning is done, reset the filter cleaning reminder indicators by pressing on blower button for
3 seconds during the 30 seconds the 3 blower button LED indicators flash slowly.
BLOWER BUTTON
When blower is OFF, press this button to turn ON the blower at the last saved speed. If there was
no speed saved, the blower will be set on LOW speed.
NOTE: When LOW speed is activated from OFF, the blower starts on MEDIUM speed for a very
short lapse of time, and then resume to LOW speed.
To change the blower speed, press on this button again until the desired speed is reached (from
LOW to MEDIUM to HIGH speed to OFF). Each time a blower speed is activated, a beep is heard
and LED indicators light up to show the corresponding speed chosen (lower LED for LOW speed,
lower and center LEDs for MEDIUM speed and all LEDs for HIGH speed).
When blower is on (no matter the speed level), press and hold this button until the beep sound
ends; this will turn off the blower and save this blower speed to memory.
LIGHT BUTTON
When lights are OFF, press once on this button to turn ON the lights at the last saved setting. If
there was no light setting saved, the lights will be set on LOW intensity. Press another time to set
the lights on HIGH intensity. Pressing another time after the HIGH setting will turn OFF the lights.
Each time the lights are turned ON, a beep is heard and LED indicators light up to show the
corresponding intensity chosen (lower LED for LOW and both LEDs for HIGH).
When lights are on (no matter the lighting level), press and hold this button until the beep sound
ends; this will turn off the lights and save the chosen light intensity.

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 fan blade should
also be replaced.
GREASE FILTERS
The grease filters should be cleaned frequently. Use a warm dishwashing detergent solution.
Grease filters are dishwasher safe.
Clean all-metal filters in the dishwasher using a non-phosphate detergent. Discoloration of the
filters may occur if using phosphate detergents, or as a result of local water conditions - but this
will not affect filters performance. This discoloration is not covered by the warranty. To minimize or
prevent discoloration, hand wash filters using a mild detergent.
NON-DUCTED RECIRCULATION FILTERS
The non-ducted recirculation filters should be changed every 3 to 6 months. Replace more often
if your cooking style generates extra grease, such as frying and wok cooking. Refer to installation
instructions included with non-ducted recirculation filters.
FAN BLADE
The fan blade should be cleaned frequently.Use a clean cloth soaked with warm detergent solution.
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 construction/
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.
PAINTED FINISH CLEANING:
Clean with warm water and mild detergent only. If discoloration occurs, use a finish polish such
as automotive polish. (DO NOT use rough abrasive cleaner or porcelain cleaner.)

NOTE: Distances over 24” are at the installer and user discretion.
1 ] Determine whether hood will discharge vertically (3¼” x 10” or 7” round),
or horizontally (3¼” x 10” only).
2 ] Decide where the ductwork will run between the hood and the outdoors.
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. When possible, use at least 2 foot straight runs before any turns. Larger ductwork
may be required for best performance with longer duct runs.
NOTE: To use 6” round ducting, install a 3¼” x 10” to 6” round transition (not included). The
performances may be affected.
4 ] Install wall cap or roof cap (sold separately). Connect metal ductwork to cap and work back
towards the hood location. Use 2” metal foil duct tape to seal the joints between ductwork
sections.
