CLEANING AND MAINTENANCE
CLEANING 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 hood liner is easily visible, and can be cleaned according to visual preferences.
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 LINER
Wipe down the interior of the hood liner 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.
Follow all label instructions. Do not polish across the grain or in circles. Do not use acids,
abrasives, strong detergents, degreasers, solvents, or scouring pads.
BLOWER 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
2Blower shield
SHIELD
The blower shields are easily removed for cleaning by pulling the blower shield(s) toward the front
of the hood.
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 shield. (Details follow)

BLOWER HOUSING
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.
3. While pulling it back, gently “tip” it downward to clear the blower wheel(s).
CLEANING
Clean the shield(s) and/or blower housing(s) in a sink of warm soapy water (liquid dish detergent)
and let soak for a few minutes. Wash with a sponge or dishcloth, rinse and let drain before
reinstalling. Alternatively, the blower housing(s) and blower shield(s) may be placed into a
dishwasher.

CLEANING AND MAINTENANCE (CONT.)
BLOWER 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 (1) that tightens up against
a “flat” spot on the motor shaft. (See illustration on previous page.)
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(2) that may be affixed to the wheel (1).
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 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 motor 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 hood inserts 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.

EN

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 hood behind/above blowers - 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 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 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 in
“Blower Wheel Removal” on page 8.
2. Use a ¼” nut driver to remove the three motor mount
screws that attach the motor to the hood.
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.

DUCTING DO’S AND DON’TS
GENERAL REQUIREMENTS
Observe local codes regarding special duct requirements and placement of duct against
combustibles.
• Using recommended transitions (see VENT ACCESSORIES) will ensure proper efficiency.
• Using recommended roof jacks or wall louvers (see VENT ACCESSORIES) will ensure proper
efficiency.
• Where possible, seal joints with foil HVAC tape (not gray cloth duct tape).
• The hood must be ducted to the outdoors without restrictions.
BLOWER REQUIREMENTS
The single blower unit (WM1L, used in 900 CFM systems) requires 6” round duct or equivalent
(28 square inches), and the dual blower unit (WM2L, used in all systems) requires 8” round duct or
equivalent (50 square inches).
COMBINED DUCT SIZE AFTER A TRANSITION
Single and Dual (WM1L & WM2L) combine to 10” round or equivalent 79 sq. in. AKVT6810
(Optional)
Two Duals (Two WM2Ls) combine to 12” round or equivalent 113 sq. in. AKVT8812 (Optional)
DUCTING REQUIREMENTS
• 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 REQUIREMENTS
Airflow must not be restricted at the end of the duct run.
A wall louver or roof jack is required for each duct run.
Every wall louver or roof jack must include a gravity damper to prevent back drafts.
Do not use screen wire or spring-loaded doors on wall louvers or roof jacks.
Do not terminate venting into
an attic or chimney. YES
