|---|
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 the 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 a qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction.
• 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 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 to the outdoors.
• 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.
• As an alternative, this product may be installed with the UL-approved cord kit designated for the product, following instructions packed with the cord kit.
• 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:
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.
| • For indoor use only.
• For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
• 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” for electric range or 26” for gas range and at a recommended maximum of 30” above the cooking surface (at installer discretion).
• Always follow 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.
• Always use tools appropriate for the task being performed.
