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 the service disconnecting means to prevent power from

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 a qualified
person(s) 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
guideline and safety standards such as those published by the
National Fire Protection Association (NFPA), and the American
Society of 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. To reduce the risk of fire or electric shock, do not use this range
hood with an additional speed control device.
7. Ducted fans must always be vented to the outdoors.
8. To reduce the risk of fire, use only metal ductwork.
9. This unit must be grounded.
TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
1. 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.
2. Always turn hood ON when cooking at high heat or when cooking
flaming foods.
3. Clean ventilating fans frequently. Grease should not be allowed to
accumulate on fan or filter.
4. Use proper pan size. Always use cookware appropriate for the
size of the surface element.

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.

ready know how to operate it.
B. The fire is small and contained in the area where it started.
C. The fire department is being 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 general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
2. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off power
