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 iisted 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
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 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 pre-
vent 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 Iocal code authorities.

5. When cutting or drilling into walI or ceiling, do not damage electri-
cal wiring and other hidden utiIities.

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 spiilovers that may ignite. Heat oils
slowly on low or medium settings.

2. Always turn hood ON when cooking at high heat orwhen cooking
flaming foods.

3. Clean ventilating fans frequently. Grease should not be allowed to
accumulate on fan or fiIter.

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.

1. For generaI ventilating use only. Do not use to exhaust hazard-
ous or explosive materials and vapors.

2. To avoid motor bearing damage and noisy and/or unbalanced
impe!Iers, keep drywaiI spray, construction dust, etc. off power

unit.

3. For best capture of cooking impurities, your range hood shouid
be mounted so that the top of the hood is 24-30" above the cook-

ing surface.
