WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

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.
Before servicing or cleaning unit, switch power off at service panel and lock 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.
Installation work and electrical wiring must be done by qualified personnel in accordance with all applicable codes and standards, including fire-rated construction codes and standards.
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.
When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
Ducted fans must always be vented d outdoors.
To reduce the risk of fire or electric shock, do not use this unit with any additional solid-state speed control device.
To reduce the risk of fire, use only metal ductwork.
This unit must be grounded.
All tempered glass can experience spontaneous breakage. If broken, tempered glass falls out of it’s opening in interlocking clumps. Tempered glass can, on occasion, break into large shards rather than the classic tiny piece pattern.
When applicable local regulations comprise more restrictive installation and/or certification requirements, the aforementioned requirements prevail on those of this document and the installer agrees to conform to these at his own expense.

TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:

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.
Always turn hood ON when cooking at high heat or when flambeing food (i.e.: Crêpes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).
Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan, filters or in exhaust ducts.
Use proper pan size. Always use cookware appropriate for the size of the surface element.

WARNING
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING*:

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.
NEVER PICK UP A FLAMING PAN — You may be burned.
DO NOT USE WATER, including wet dishcloths or towels — This could cause a violent steam explosion.
Use an extinguisher ONLY if:
You own a Class ABC extinguisher and you know how to operate it.
The fire is small and contained in the area where it started.
The fire department has been called.
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 impellers, keep drywall spray, construction dust, etc. off power unit.
Your hood motor has a thermal overload which will automatically shut off the motors if it overheats. The motors will restart when cooled down. If the motor(s) continues to shut off and restart, have the hood serviced.
The minimum hood distance above cooktop must not be less than 24″. A maximum of 30″ above cooktop is highly recommended for best capture of cooking impurities. For a gas range, the bottom of the hood MUST NOT BE LESS than 30” above cooktop.
Two installers are recommended because of the large size and weight of this unit.
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.
Because of the high exhausting capacity of this unit, you should make sure enough air is entering the house to replace exhausted air by opening a window close to or in the kitchen.
Use with approved cord-connection kit only.
Please read specification label on product for further information and requirements.

INSTALL DUCTWORK

Plan where and how the ductwork will be installed.
The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow. Refer to the table at the bottom of this page to help you plan the most efficient installation.
Install wall or roof cap; once done, ensure there is no leak in house insulation. Connect metal ductwork to cap and work back towards the hood location. If 6” round ducts are installed, use a 3¼” x 10” to 6” transition positioned, if possible, 18” away from the adapter/damper. Use 2” metal foil duct tape to seal the joints.
We recommend to install the hood at a minimum distance of 24” from an electric range and of 30” from a gas range.
Distances over 30” are at the installer and users discretion.

LED LIGHTING

The lighting of this hood is produced by two LED modules (included).

CARE

HYBRID FILTERS AND BOTTOM PANEL

The hybrid filters and the bottom panel should be cleaned frequently. Use a warm detergent solution.
Remove hybrid filters by pushing them towards the back of hood and rotating downward.
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 — this will not affect filter performance. This discoloration is not covered by the warranty. To minimize or prevent discoloration, hand wash filters using a mild detergent.

STAINLESS STEEL

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 hood to make sure no dust sticks to stainless steel surfaces.

GLASS PANEL

Hot water with mild soap or glass cleaner is all that is usually needed.
When using mild soap, rinse with clear water. Wipe dry with a clean, soft cloth to avoid water marks.

Avoid when choosing a detergent:

Any cleaners that contain bleach. They will attack stainless steel.
Any products containing chloride, fluoride, iodide, bromide. They will deteriorate surfaces rapidly.
Any combustible products used for cleaning such as acetone, alcohol, ether, benzol, etc. They are highly explosive and should never be used close to a range.

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.

CAUTION
After a power failure or during the range hood power up, a 5-second booting sequence is executed. Wait for the control backlighting to turn off before use.

DELAY BUTTON/CONTROL LOCK (DOUBLE FUNCTION BUTTON):
When a blower speed is selected, press this button to activate the delay function. The delay button will light to its high intensity, then to its mid intensity to indicate this function is activated; the selected blower speed button will alternate every 2 seconds from its high intensity to its mid intensity. The blower will continue to operate for 5 minutes and will stop automatically. Selecting an other speed while the delay function is activated will not deactivate the function or reset the timer. To cancel the delay function, press the delay button once again, or press the selected speed button which will also turn the blower off.
When blower is off, it is possible to lock the control interface in order to clean the glass panel.
To lock the control interface: Press and hold the button for 2 seconds. The button will light to its high intensity and flash three times, it will then stay on its mid intensity to indicate that the control interface is locked.
To unlock the control interface: Press and hold the button for 2 seconds. The button will light to its high intensity and flash 3 times, it will then fade out to its low intensity to indicate that the control interface is unlocked.
SPEED SELECTION BUTTONS:
Press the button corresponding to the desired blower speed (from 1 for low speed to 4 for high speed). The chosen speed button will light to its high intensity then fade to its mid intensity. To turn off the blower, press once more on the corresponding blower speed button; the button light will fade to its low intensity
NOTE: When blower is off, pressing on blower speed 1 button will cause the blower to start on second speed for a very short lapse of time,
and then resume on speed 1.
NOTE: To decrease the maximum airflow from 600 CFM to 300 CFM, follow the instructions of the 300 CFM CRT kit (included with the
unit, envelope no. 23894, or order SV23894 part).
MASTER ON/OFF:
When blower and lights are off, press this button to turn the hood on to the last memorized speed level. If there is no memorized speed level, speed will be set at level 1 and light intensity at 3. To turn off the blower and the light simultaneously, press this button once.
HEAT SENTRY™: The hood is equipped with a HEAT SENTRY thermostat. If blower is ON at a lower speed setting and excessive heat is
detected above the cooking surface, it turns the blower up to third speed. When the temperature level drops to normal, the blower will return to its original setting.
NOTE: When Heat Sentry is activated, the “DELAY OFF” function is inactivated.
LIGHT BUTTON/BACKLIGHTING COLOR (DOUBLE FUNCTION BUTTON):
This button allows three different lighting levels according to your needs. Press once for full intensity, twice for intensity level 2, and once more for nightlight. To turn off the lights, press once more.
If desired, when the lights are on, press and maintain the light button for 1 second; lights will be turned off.
NOTE: When only the lights are ON to any intensity and no interaction with the hood is detected for a 10-second period, the 7 buttons backlighting will fade to its low intensity, acting as a night light feature.
When lights are off, pressing and holding this button for 1 second will switch the backlighting color from white to blue or from blue to white (default backlighting color is white) and memorize it. The button will flash three times to indicate that the color change has been made.
NOTE: Due to the particular sensitivity of the control interface, keep the glass panel clean as dirt and condensation may cause erratic operation of the hood blower and/or lighting. If this situation occurs, wipe the glass panel and wait 90 seconds. Then, adjust the blower and/or lighting at your convenience.
