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.
WARNING
To reduce the risk of fire, electric shock, or injury to persons, observe the following:
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 back drafting. 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:
1. Never leave surface units unattended at high settings. Over heat 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 flambéing food (i.e. Crepes Suzette,
Cherries Jubilee, Peppercorn Beef Flambé).
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.

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.
WARNING
To reduce the risk of injury to persons in the event of a range top grease fire, observe the
following:
2. Never pick up a flaming pan - You may be burned.
3. Don’t use water, including wet dishcloths or towels - violent steam explosion will result.
4. Use an extinguisher only if:
 You know you have a Class ABC extinguisher and you already know how to operate it.
 The fire is small and contained in the area where it started.
 The fire department is being called.
 You can fight the fire with your back to an exit.
* Based on “Kitchen Fire Safety Tips” published by NFPA.
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.
CAUTION
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 33" above the cooking surface.
8. Two 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.
11. Please read specification label on product for further information and requirements.

This range hood must be properly grounded. The unit
should be installed by a qualified electrician in
accordance with all applicable national and local
electrical codes.
The minimum hood distance above cook top must not be
less than 24’’. A maximum of 33” above cook top is highly
recommended for best capture of cooking impurities.
Distances over 33” are at the installer and users
discretion.
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.
2. A straight, short duct run will allow the hood to perform most efficiently.
3. Install the Aluminum Flex duct on the vent towards hood location.

1. After evaluating the height of the hood, place the hook
center over installation location. Drill 3 holes of Ø8mm on
a suitable place to fix the mounting brackets.
INSTALL MOUNTING BRACKETS
2. Put the drywall anchors into the holes and fix the
mounting screws (4x40mm) into the anchors, and install
the hook on the wall as shown.
INSTALL SLIDERY DUCT, FIXING SUPPORT
1. Calculate the final height of the U-shaped section, drill 2
holes of Ø8mm on a suitable place in line with the slider
duct fixing support.
2. Put the drywall anchors into the holes and fix the
mounting screws (4x40mm) into the anchors, and install
the hook on the wall as shown.

Note: at least two people will be required to mount the hood.
INSTALL THE HOOD
1. Raise the hood into its mounting position.
2. Align the rectangular opening on the back of
the hood with the wall-mounting bracket. Gently
lower the hood until it securely engages the
bracket.
3. Open the Al. filter and find the two φ8 mm
holes on the back of the hood. Level the hood
with 2 mounting screws (4*30mm) with washer.
Use drywall anchors provided.
4. Measure the height of the glass to the slider duct fixing
support. Adjust the height of the chimney according to the
height. Then use the duct fixing support with two screws
(4x8mm) to fix the chimneys. Shown as in the picture.
5. Put the chimney on the hood, use two screws (4x8mm)
to fix the chimney to the slider duct fixing support.
6. Use the other two screws (4x8mm) to fix the bottom of
chimney.
7. After adjusting the position, open the filter and fix

MAINTENANCE
Proper maintenance of the Range Hood will assure proper performance of the unit.
Filters
The filters must be cleaned approximately
once every 30 hours of operation (when
the central segment on the display goes
on or starts blinking).
Use a warm detergent solution. Grease
filters are dishwasher safe.
Remove filter by pushing filter towards the
back of hood and rotating filter downward.
Duct free (Carbon) Filters-buy separately
The duct free filters should be changed every 6 months. Rotate the filters to remove and replace.
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 mar the surface.
 Don’t allow deposits to remain for long time.
 Don’t use ordinary steel wool or steel brushes. Small bits of steel may adhere to the surface
causing rust.
 Don’t allow salt solutions, disinfectants, bleaches, or cleaning compounds to remain in contact
with stainless steel for extended periods. Many of these compounds contain chemicals which
may be harmful. Rinse with water after exposure and wipe dry with a clean cloth.
Painted surfaces should be cleaned with warm water and mild detergent only.
