FOR GENERAL VENTILATING USE ONLY. DO NOT USE TO
EXHAUST HAZARDOUS OR EXPLOSIVE MATERIALS AND VAPORS.
TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
a) Never leave burners or 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 burner or surface
element.
TO REDUCE THE RISK OF INJURY TO PERSONS, IN THE EVENT OF
A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING *:
a) 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.
b) NEVER PICK UP A FLAMING PAN - You may be burned.
c) DO NOT USE WATER, including wet dish cloths or towels - a violent steam explosion will
result.
d) Use an extinguisher ONLY IF:
1. You have a Class ABC or Class K fire extinguisher and you already know how to operate it.
2. The fire is small and contained in the area where it started.
3. The fire department is being called.
4. You can fight the fire with your back to an exit.

CLEANING AND MAINTENANCE
CLEANING THE VENTILATION SYSTEMCLEANING THE VENTILATION SYSTEM
Cleaning requirements depend completely on usage and environment. The more high-heat and/or
greasy cooking, the more often the hood and blower will need cleaning.
The grease tray and blower aren’t visible from the outside, so they must be removed for inspection.
After you’ve inspected the tray a few times over the course of six months or a year, you’ll be able to
set a cleaning schedule according to your usage pattern.
HOOD CANOPYHOOD CANOPY
Wipe down the interior and exterior of the hood as needed with a soft cloth and warm soapy
water (liquid dish detergent is acceptable). Do not use acids, abrasives, strong detergents, solvents,
or scouring pads. Stainless steel should be treated with a quality stainless steel cleaner such as
Stainless Steel Magic®. Follow all label instructions. Do not polish across the grain or in circles.
BLOWER HOUSING AND SHIELDBLOWER HOUSING AND SHIELD
To reduce the risk of personal injury, be sure the power is turned off in
the hood before removing the shield(s) and blower housing(s).
The blower captures grease by-products in the blower housing(s) and blower shield(s). The blower
shields require more frequent cleaning than the blower housing, but cooking usage determines how
often each item will need to be cleaned.
Item # Description
1Blower housing with damper(s)
2Blower shield
BLOWER SHIELD REMOVALBLOWER SHIELD REMOVAL
The blower shields are easily removed for cleaning by pulling the blower shield(s) away from the
blower housing in the direction shown above.
Be careful to keep the tray level if the hood has been recently used and the
grease might still be warm.
Inspect and clean the blower shield (Details follow)
BLOWER HOUSING REMOVALBLOWER HOUSING REMOVAL
To remove the blower housing:
1. Unsnap two suitcase latches, one on each side of the housing.
2. Support the housing and pull it away from the blower base.

CLEANING AND MAINTENANCE (CONT.)
BLOWER WHEEL REMOVALBLOWER WHEEL REMOVAL
For instances where the blower wheel must be removed, follow the instructions below.
• Removing the blower wheel requires a 1/8” hex wrench. This may be obtained from your local
hardware store or tool supply.
The wheel is retained by a set screw on the side of the hub of the wheel that tightens up against a
“flat” spot on the motor shaft.
1. Locate the set screw on the side of the hub of the wheel.
2. Insert wrench through the blades of the blower wheel and into the set screw.
3. Loosen the set screw 1/2 turn counterclockwise.
If the wheel is difficult to remove, the area where the motor shaft makes contact with the
blower wheel hub may need to be sprayed with a common penetrating oil such as WD-40®.
After allowing the penetrating oil to soak for a few minutes, push the blower wheel forward
slightly, then gently pull the blower wheel off the motor shaft.
• Use caution to avoid bending or distorting the blower wheel and take care not to move or lose
the metal balancing clips that may be affixed to the wheel.
A soft bristle toothbrush with warm soapy water may be used to clean the blades, or soak the
blower wheel in warm soapy water.
BLOWER WHEEL INSTALLATIONBLOWER WHEEL INSTALLATION
When reinstalling the wheel onto the motor shaft, make sure the set screw makes direct contact
with the “flat spot” on the motor shaft.
1. Slide the blower wheel onto the motor shaft as far as it will go, making sure the back of the
blower wheel does not touch the motor mount screws protruding from the motor.
• If the wheel is too far back, it will rub the motor mount screws, and if it is too far forward, it
will rub the inside of the blower housing.
2. Adjust the blower wheel slightly to find the correct front-to-rear location.
3. Tighten the set screw (clockwise) to lock the blower wheel in the correct position.
For hoods that have more than one blower wheel, make sure that white
blower wheels are matched up with white motor rings, and black blower
wheels are matched up with black motor rings.
The hood will not perform properly if blower wheels and motors are mismatched.

TROUBLESHOOTING
If the hood does not perform satisfactorily, check the following:
• Do the blowers run?
• Are the blower wheels installed on the correct motors? (black wheel on black motor, white
wheel on white motor)
• Are the motor and wheel assemblies installed in the correct locations?
• Check the damper doors in blower housing(s) - do they move/open freely?
• Check the dampers/vents to outside - do they open freely, with no obstructions?
• Check for damaged or obstructed ductwork.
MOTOR REPLACEMENTMOTOR REPLACEMENT
To reduce the risk of personal injury, turn off power to the hood at
the breaker or the circuit disconnect before attempting to remove the
blower motor.
MOTOR IDENTIFICATION AND POSITIONINGMOTOR IDENTIFICATION AND POSITIONING
Motors are color-coded; black and white motors have different rotations and must be installed in
the correct positions.
• Housings with a single blower use a white blower and wheel.
• Housings with two blowers use a white blower on the right and black on the left.
Make sure you have the correct motor in each housing position.
• If the replacement blower motor includes a blower wheel, then you can remove the motor and
wheel together. If you will re-use your existing wheel, then you may wish to remove the wheel
before removing the motor.
1. Remove the shield and blower housing as described on
page6.
2. Use a ¼” nut driver to remove the three motor mount
screws that attach the motor to the base.
3. Gently pull the motor forward and down.
4. Disconnect the wiring harness, remove the old motor.
• To avoid damage to the blower wheel, you may wish to
install the motor and then install the wheel onto the motor.
5. Lift the new motor so you can connect the wiring
harness. Be sure to fully engage the electrical
connections and tighten the motor mount screws.
6. Check the blower wheel clearance and adjust
as needed, as described in “BLOWER WHEEL
INSTALLATION” on page8.

EN
GENERAL REQUIREMENTSGENERAL REQUIREMENTS
Observe local codes regarding special duct requirements and placement of duct work against
combustibles.
• Using recommended transitions (included) will ensure proper efficiency.
• Using recommended roof caps or wall louvers (see VENT ACCESSORIES) will ensure proper
efficiency.
• Use foil HVAC tape (not grey cloth duct tape) to seal all joints.
• The hood must be ducted to the outdoors without restrictions.
BLOWER REQUIREMENTSBLOWER REQUIREMENTS
The island dual blower unit (T200 = 550 CFM) used in 36” and 42” systems, outputs through the
included transition to 8” round duct or equivalent. (50 sq. inches)
The 54” system uses a cluster of four blowers (T400 = 1100 CFM) which output through the
included transition to 12” round duct or equivalent. (113 sq. inches)
DUCTING REQUIREMENTS (DO’S AND DON’TS)DUCTING REQUIREMENTS (DO’S AND DON’TS)
• NEVER reduce the duct size. When combining ducts together, the square inch area of
the outlet duct must be equal or greater than the total square inch area of the ducts being
combined.
• Only use smooth galvanized metal duct. Do not use flexible or corrugated duct. This type of
duct will restrict airflow and reduce performance.
• Make the duct run as short and as straight as possible with as few turns as possible.
• Avoid sharp-angled turns. Instead, use smooth, gradual turns such as adjustable elbows or 45
degree angled turns.
• For duct runs over 20 feet, increase the duct diameter by one inch for every ten feet of duct.
• When planning length, a 90 degree elbow is equivalent to 5 feet of duct.
TERMINATION REQUIREMENTSTERMINATION REQUIREMENTS
Airflow must not be restricted at the end of the duct run.
A wall louver or roof cap is required for each duct run.
Every wall louver or roof cap must include a gravity damper to prevent back drafts.
Do not use screen wire or spring-loaded doors on wall louvers or roof caps.
Do not terminate venting into an attic or chimney.

INSTALLATION
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO
PERSONS, OBSERVE THE FOLLOWING:
a) Load-bearing framework in the ceiling is necessary for the installation of an island hood.
Additional framework construction may be required. Do not attach an island hood to a structure
that cannot support twice the weight of the hood and (optional) duct covers. For weights of
hoods, see the Dimensions table on page13, and “Duct Covers” on page16.
b) Installation work and electrical wiring must be done by qualified person(s) in accordance with all
applicable codes and standards, including fire-rated construction.
c) Sufficient air is needed for proper combustion and exhausting of gases through the flue
(chimney) of fuel burning equipment to prevent back drafting. 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 for Heating, Refrigeration, and Air
Conditioning Engineers (ASHRAE) and the local code authorities.
d) When cutting or drilling into ceiling, do not damage electrical wiring and other hidden utilities.
e) Ducted fans must always be vented to the outdoors.
TO REDUCE THE RISK OF FIRE, USE ONLY METAL DUCTWORK.
