WARNING WARNING

- 2 -

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

1. 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.

2. 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.

3. 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.

4. 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.

5. When cutting or drilling into wall or ceiling, do not

damage electrical wiring and other hidden utilities.

6. Ducted fans must always be vented to the outdoors.

7. Do not use this unit with any other solid-state speed

control device.

8. To reduce the risk of fire, use only metal ductwork.

9. This unit must be grounded. To provide protection

against electric shock, connect to properly grounded outlets only.

10. 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 expenses.

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 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 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

1. For indoor use only.

2. For general ventilating use only. Do not use to exhaust

hazardous or explosive materials and vapors.

3. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.

4. 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.

5. The minimum hood distance above cooktop must not be less than 24”. A maximum of 30” above cooktop is recommended for best capture of cooking impurities.

6. Two installers are recommended because of the large size and weight of this unit.

7. 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.

8. This product is equipped with a thermostat which may start blower automatically. To reduce the risk of injury and to prevent power from being switched on accidentally, switch power off at service panel and lock or tag service panel.

9. Because of the high exhausting capacity of this hood, you should make sure enough air is entering the house to replace exhausted air. Use an appropriate make-up air device or open a window close to or in the kitchen.

10. To reduce the risk of fire and electrical shock, the Best WT32I Series models should only be installed with their own built-in blower(s).

11. Please read specification label on product for further information and requirements.

GROUNDING INSTRUCTIONS This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.

WARNING

Improper grounding can result in a risk of electric shock. Consult a qualified electrician if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded. Do not use an extension cord. If the power supply cord is too short, have a qualified electrician install an outlet near the appliance, in accordance with all applicable codes and standards. Turn off electrical power at service entrance before wiring.

HD0376

Using a level, draw a vertical line up to the ceiling starting from the mounting bracket center.

Position the outlet within the space covered by the decorative flue. Place the outlet at a maximum distance of 24” (from where the cord exits from the hood). If installing a 30”, 36” or 42” width hood, the center of the outlet must be positioned at 2¾” from the center of the future hood location. If installing a 48” width hood, the center of the outlet must be positioned at 3¾” from the center of the future hood location (as illustrated beside). Make sure this does not interfere with a mounting bracket fastening area or with the decorative flue (where the flue touches the wall).

The WT32I Series range hood can be connected to the optional make-up air device (models MD6TR or MD8TR). Position the relay on the wall within the space covered by the lower decorative flue (relay provided in the make-up air device kit).

15. CARE

WARNING

Before servicing or cleaning the unit, switch power off at service panel and lock service panel 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.

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.

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 surface.

Grease Filters

Grease filters should be cleaned monthly. Remove grease filters by pulling down on the metal latch tab. This will disengage the filter from the hood. Tilt the filter downward and remove. Use a warm detergent solution to clean the filters. Let them dry and reinstall them.

Grease filters are dishwasher safe. Clean all-metal filters in the dishwasher using a non-phosphate detergent. Discoloration of the filter may occur if using phosphate detergent or as a result of local water conditions — but this will not affect filter performance. This discoloration is not covered by the warranty.

Interior Blower(s) Cleaning

Remove the filters in order to access the blower(s). Vacuum blower(s) to clean. Do not immerse in water.

Hood Cleaning
