WARNING
WARNING
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 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 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 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. To reduce the risk of fire, use only metal 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
flambeing 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 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 - violent steam explosion will result.
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.
