!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 wheels, 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
5
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.
Operate the hood as follows:
BLOWER ACTIVATION/SPEED LEVEL CHANGE/FILTER INDICATOR RESET
When blowers are OFF, press on this push button to turn ON the blowers at the last saved speed.
If there was no speed saved, the blowers will be set on LOW speed.
NOTE: When LOW speed is activated from OFF, the blowers start on MEDIUM speed for a very
short lapse of time, and then resume to LOW speed.
To change the blower speed, press 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 rotating blower
icon appears on left side of LCD screen, with dot(s) under it (slow for LOW with one dot, faster for
MEDIUM with 2 dots and fastest for HIGH with 3 dots).
When blowers are on (no matter the speed level), press and hold this button until the blower icon
disappears from the LCD screen; this will turn off the blowers and save the blower speed chosen.
Heat Sentry™
This hood is equipped with a protective device that activates the blowers when an abnormally high
heat level is detected while the blowers are activated. During the Heat Sentry activation, this device
takes control of the blowers and set them on MEDIUM speed while all dots under the blower icon
blink. However, the lights can be still controlled. The blowers will remain on MEDIUM speed until
the heat is back to normal, they then return to the speed previously selected.
NOTE: When excessive heat is detected, Heat Sentry will shut off both blowers and lights while all
dots under the blower icon will blink faster. Both blowers and lights will remain off until the
ambient temperature cools down; the blowers will then start on MEDIUM speed (the lights
can be controlled again).The blowers will remain on MEDIUM speed until the heat is back
to normal, they then return to the speed previously selected.
NOTE: At range hood start-up or after a power failure, a small icon (1) appears shortly
(for ± 2 seconds) on LCD screen; this is normal.
FILTER CLEANING REMINDER
This icon appears on LCD screen 30 seconds after turning OFF the blowers when it is time to
clean hood and filters (refer to Cleaning and Maintenance on page 7). This happens every time
the blowers are turned OFF until the filter cleaning reminder has been reset. Once the cleaning is
done, reset the filter cleaning reminder by pressing on blower activation push button for 3 seconds
while the icon appears on LCD screen for 30 seconds.

ON LIGHTING/LIGHT INTENSITY CHANGE
Press this button to turn on the lights at the last saved intensity; the light icon appears on right side
of LCD screen and the number of dots below it shows which light intensity is on (one dot for LOW,
two dots for MEDIUM and three dots for HIGH).
To change the light intensity, press button until the desired level is reached (from HIGH intensity,
pressing again will shut off the lights).
When lights are on (no matter the light intensity), press and hold this button until the light icon
disappears from the LCD screen; this will shut off the lights and save the chosen light intensity.
MASTER ON/OFF
Press this button to turn on the ligths and the blowers at the last saved intensity. When either lights
or blowers are ON, pressing this button will memorize the current blower speed and lighting level
prior to shut them OFF.
DELAY OFF
When the blowers are on, press this button to activate the delay function.This icon appears on LCD
screen beside the blower icon to indicate the function is on.The blowers will continue to operate for
10 minutes and then, will shut off automatically (both blower and delay icons will disappear from
LCD screen).When Delay off is activated, it is possible to change the blower speed by pressing on
blower push button without affecting the remaining time of the delay.
To cancel the delay off function before the end of the 10-minute cycle, press this button again.

CLEANING AND MAINTENANCE
7
Cleaning and Maintenance
Proper maintenance of the Range Hood will assure proper performance of the unit.
MOTORS
The motors are permanently lubricated and never need oiling. If the motor bearings make
excessive or unusual noise, replace the motor with the exact service motor. The fan wheel 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 filter performance. This discoloration is not covered by the warranty.
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 WHEELS
The center of the fan wheels 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.
4 ] Install wall cap or roof cap (sold separately); ensure there is no leak in house insulation.
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.
