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 any questions,
contact the manufacturer at the address or telephone number listed in the warranty.

2. Before servicing or cleaning unit, switch off power at service panel and lock 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 qualified person(s) in accordance
with all applicable codes and standards, including fire-rated construction.

4. Sufficient air is needed for power 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. Do not use this unit with any separate solid-state speed control device.

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:

A . 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.

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 ventilating 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
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 - a 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. 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.

2. Take care when using cleaning agents or detergents.

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

4. For general ventilating use only. Do not use to exhaust hazardous or explosive mate­rials and vapors.

5. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall
spray, construction dust, etc. off power unit.

6. 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.

7. For best capture of cooking impurities, the bottom of the hood should be a minimum of
23-5/8" and a maximum of 30" above the cooking surface.

8. Three installers are recommended because of the large size and weight of this hood.

9. 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.

10 . Use with approved cord-connection kit only.

FUSE REPLACEMENT

IF LIGHTS FAIL TO OPERATE, DISCON­NECT POWER AT THE SERVICE EN­TRANCE. CHECK THE FUSE AND RE­PLACE IF NECESSARY.

1. Remove the grease filters.

2. Unscrew the cap from the fuse holder
and remove the fuse.

3. Replace the fuse with the same size and
amperage (5 x 20mm, 4 amp, 125 volt).

!

CAUTION: Use a fuse greater than 4

amps may damage the transformer.

4. Reinstall the fuse holder cap.

5. Reconnect power at the service entrance.

FUSE

HALOGEN BULBS

This range hood requires four halogen bulbs
(Type T3, 12Volt, 20Watt Max, G-4 Base).

WARNING: Always switch off the elec-

trical supply before carrying out any op­eration on the appliance.

To change bulbs:

1. Open the cover by prying from the proper
slots.

2. Remove the bulb by pulling sideways. (DO
NOT ROTATE).

!

CAUTION: Bulb may be hot.

3. Replace with Type T3, 12Volt, 20 Watt Max, G-4 Base halogen bulb. Do not touch
replacement bulb with bare hands!

!

CAUTION: Use of bulbs greater than 20 watts will cause the fuse to open.

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.

INSTALL THE DUCTWORK

(DUCTED HOODS ONLY)

!

WARNING: To reduce the risk of fire,

use only metal ductwork.

1. Decide where the ductwork will run
between the hood and the outside.

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 longer duct runs.

4. Install a roof or wall cap. Connect round
metal ductwork to cap and work back to­wards hood location. Use duct tape to seal
the joints between ductwork sections.

such a way that the two slots are plugged.
Each bracket must be fixed with (2) 3.9 x 6
mm mounting screws (Fig. 4).

2. Attach the discharge collar onto the hood
(Fig. 5); it must be attached by means of 4
mounting screws (3,9x9,5 mm Pan Head).

3. Remove the tape located on the damper
(Fig. 5).

4. Attach an adequate length of 8” round
steel ducting to the range hood discharge
collar (Fig. 6).
Duct tape all joints to make them secure
and air tight.

5. If the ductwork is placed on the wall (and
not on the ceiling), read the following
instructions:

- disassemble the motor block (included
the plate where it is fixed) unscrewing the
4 screws (Fig. 7).

- rotate motor block in order to have the
duct connector toward the wall.

- use the same screws to fix the motor
block in the new position (Fig. 8).
