WARNING

TO REDUCE THE RISK OF FIRE, ELECTRICAL 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 service

panel 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 accor-

dance 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 equip-

ment 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.

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. Do not use this unit with any separate solid-state speed control device.

8. To reduce the risk of fire, use only steel ductwork.

9. This unit must be grounded.

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

t

hat 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. Crepes

Suzette, Cherries Jubilee, Peppercorn Beef Flambe’).

C. Clean ventil

ating fans frequently. Grease should not be allowed to accumulate on fan or filter.

D. Use proper pan size. Always use cookware appropriate for the size of the surface element.

WARNING

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 indoor use only.

2. To reduce risk of fire and to properly exhaust air, be sure to duct air outside. Do not vent

exhaust air into spaces within walls or ceilings or into attics, crawl spaces, or garages.

3. Take care when using cleaning agents or detergents.

4. Avoid using food products that produce flames under the Range Hood.

5. For general ventilating use only. Do not use to exhaust hazardous or explosive materi-

als and vapors.

6. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall

spray, construction dust, etc. off power unit.

7. 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.

8. For best capture of cooking impurities, the bottom of the hood should be a minimum of

24" and a maximum of 30" above the cooking surface. See page 9 for mounting restric-

tions.

9. Two installers are recommended because of the large size and weight of this hood.

10. This product is equipped with a thermostat which may start blower automatically. To

reduce the risk of injury and to prevent power from being switched on accidentally,

switch power off at service panel and lock or tag service panel.

11. Use with approved cord-connection kit only.

12. Please read specification label on product for further information and requirements.

run delay and blower speed settings.

Light Button, Filter Alarm, Alarm Reset:

• Turns halogen lights on and off. Press once to turn the lights ON to low level.

Press a second time to turn the lights on to a brighter level. Press a third time

to turn the light off.

• When blower is off, this switch remains lit after 30 hours of operation, indicating

a need to replace the charcoal filter.

• After filters are cleaned or replaced, press this button for one-second to reset

the filter alarm.

Blower On-Off, Speed 1

HEAT SENTRY™

Your hood is equipped with a HEAT SENTRY™ thermostat. This thermostat is a

device that will turn on or speed up the blower if it senses excessive heat above

the cooking surface.

1) If blower is OFF, it turns blower ON to HIGH speed.

2) If blower is ON at a lower speed setting, it turns blower up to HIGH speed.

When the temperature level drops to normal, the blower will return to its original

setting.

WARNING

The HEAT SENTRY thermostat can start the blower even if the hood is turned

OFF. When this occurs, it is impossible to turn the blower OFF with its switch.

If you must stop the blower, do it from the main electrical panel.

MAINTENANCE

Proper maintenance of the Range Hood will

assure proper performance of the unit.

Grease Filter

Grease filter should be cleaned when the light

switch flashes or remains lit when the blower

is off (i.e. 30 hours of operation). Use a warm

detergent solution to clean filters. Filters are

dishwasher safe. See page 12 for filter removal

and installation instructions.

Hood Cleaning

Stainless steel is one of the easiest materials to keep clean. Occasional care will

help preserve its fine appearance.

Cleaning tips:

•

Hot water with soap or detergent is all that is usually needed.

•

Follow all cleaning by rinsing with clear water. Wipe dry with a clean, soft cloth to

avoid water marks.

•

For discolorations or deposits that persist, use a non-scratching household

cleanser or stainless steel polishing powder with a little water and a soft cloth.

•

For stubborn cases, use a plastic scouring pad or soft bristle brush together with

cleanser and water. Rub lightly in direction of polishing lines or "grain" of the

stainless finish. Avoid using too much pressure which may mark the surface.

•

DO NOT allow deposits to remain for long periods of time.

•

DO NOT use ordinary steel wool or steel brushes. Small bits of steel may adhere

to the surface causing rust.

•

DO NOT allow salt solutions, disinfectants, bleaches, or cleaning compounds to

remain in contact with stainless steel for extended periods. Many of these com-

pounds contain chemicals which may be harmful. Rinse with water after expo-

sure and wipe dry with a clean cloth.

Painted surfaces should be cleaned with warm water and mild detergent only.

INSTALL THE DUCTWORK

NOTE: To reduce the risk of fire, use only metal ductwork.

1. Choose the location where the exterior blower will be mounted. See illustra-

tions below for mounting location suggestions and restrictions.

2. A straight, short duct run will allow the hood to perform most efficiently.

3. Long duct runs, elbows and transitions will reduce the performance of the

hood. Use as few of them as possible. Larger ducting may be required for best

performance with long duct runs.

4. After the exterior blower has been installed, connect round metal ductwork and

work back towards the hood location. Use duct tape to seal joints between

ductwork sections.

5. An 8” round to 10” round transition (Model 414) is required. For best air

performance, install the adapter as close to the range hood as possible.
