WARNING
TO REDUCETHE 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 or your distributor.
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 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 electri-
cal wiring and other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. To reduce the risk of fire, use only steel ductwork.
8. If this unit is to be installed over a tub or shower, it must be marked
as appropriate for the application and be connected to a GFCI
(Ground Fault Interrupter) - protected branch circuit.
9. Never place a switch where it can be reached from a tub or
shower.
10. 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 flambe-
ing food (i.e. Crepes Suzette, Cherries Jubilee, Peppercorn Beef
Flambe’).
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.
TO REDUCETHE RISK OF INJURYTO PERSONS INTHE EVENT
OF A RANGETOP GREASE FIRE, OBSERVETHE 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, EVACUATEAND
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 - violent
steam explosion will result.

WARNING
4. Use an extinguisher ONLY if:
A. You know you have a Class ABC extinguisher and you already
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
unit.
3. If ventilator is installed in an unconditioned space (such
as an attic): Surround the ventilator with thermal insulation - to
minimize possible condensation.
4. Please read specification label on product for further information
and requirements.

WARNING: To reduce the risk of electric shock,
disconnect from power supply before servicing.
To clean blower assembly: Remove access panel, unplug blower
from housing, remove blower mounting nuts, and carefully remove
blower from housing. Use appropriate vacuum attachment or a soft
cloth and mild soap or detergent to clean blower discharge area and
wheel. DO NOT ALLOW WATER TO ENTER MOTOR. Make sure
blower assembly is completely dry before reinstalling.
Motor is permanently lubricated. Do not oil or disassemble motor.
USE AND CARE
Follow wiring instructions packed with range hood, and adhere to
all local and state codes, and the National Electrical Code.
ATTACH POWER CORD TO
HOOD
Some hoods require the use of a separate power cord and strain
relief bushing (included), for proper wiring of in-line blowers.Please
refer to the hood manual for proper installation instructions.
