INTENDED FOR DOMESTIC COOKING ONLY

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 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 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
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 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.

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 24" and a maximum of 30" above the cooking
surface.

8. Two installers are recommended.

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

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.

INSTALL THE DUCTWORK

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

1. Decide where the ductwork will run between the hood and the
outside (Refer to Figure 1).

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.

INSTALL THE HOOD

NOTE: the hood has to be installed, inside the cabinet, at minimum
1” from the rear wall cabinet and at 3” from the front wall cabinet.

The internal height of cabinet has to be minimum 16”.
The hood should be mounted centered over the cook top burners.

1. Remove the grid by moving the 2 slide fasteners “A” forward (Fig.2).

2. Cut a hole in the bottom of the cabinet, using the dimensions shown
(Fig. 3).

3. Adjust the position of the clasping side spring by means of the
proper “B” screw according to the thickness of the bored panel to
which it is going to be anchored (Fig. 4).

4. NOTE: For installations where the Power Pack is less than 30”
above cook top, it is recommended that the Power Pack be
mounted into a metal liner or non-combustible material. This will
allow easier cleaning and provide protection to the cabinetry
(Fig.5A).

5. Insert the hood in the cabinet and lock it by means of the side
spring.

6. Insert the hood in the cabinet (Fig. 5) or metal liner (Fig. 5A) and
secure with the (4) “C” mounting sheet metal screws.

(Fig. 5 - wood bottom installation; recommended thickness 1/2”­3/4”).

(For alternate mounting, use machine screws with washers and
nuts. This alternate mounting method needs to be done prior to
installation of metal liner).

7. In the Non-Ducted Recirculation Configuration, install the Non­ducted recirculation Filter before replacing the grid (see section
“Non-ducted recirculation filter installation”).

8. Replace the grid.
