WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT USE THIS FAN WITH ANY SOLID-STATE CONTROL DEVICE.
WARNING
TO REDUCE THE RISK OF FIRE ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
a. Use this unit only in the manner intended by the manufacturer, if you have questions, contact the manufacturer.
b. Before servicing or cleaning unit, switch power off 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.
CAUTION
For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors. Take care when using cleaning
agents or detergents. Suitable for use in household cooking area.
WARNING
TO REDUCE THE RISK OF 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 flaming food
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.
e. Keep fan, filters and grease laden surfaces clean.
f. Use high setting on hood only when necessary.
g. Don’t leave hood unattended when cooking.
h. Always use cookware and utensils appropriate for the type of and amount of food being prepared.
WARNING
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE TOP FIRE, OBSERVE THE FOLLOWING:
a. 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.
b. NEVER PICK UPA FLAMING PAN – You may be burned.
c. DO NOT USE WATER, including wet dishcloths or towels – a violent steam explosion will result.
d. Use an extinguisher ONLY if:
1. You know you have a Class ABC extinguisher, and you already know how to operate it.
2. The fire is small and contained in the area where it started.
3. The fire department is being called.
4. You can fight the fire with your back to an exit
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
a. Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards.
Including fire-rated construction.
b. Sufficient air is needed for power combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent
back-drafting. 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.
c. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
d. Ducted fans must always vent to the outdoors.
e. 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 GFI
(Ground Fault Interrupter protected branch circuit).
g. NEVER place a switch where it can be reached from a tub or shower.
h. Make sure the power is off before installing, wiring or maintenancing.

DUCTING
A minimum of 6” round ducting must be used to
maintain maximum air flow efficiency.
Always use rigid type metal ducts only. Flexible
ducts could restrict air flow by up to 50%.
Use calculation worksheet to compute total duct
work.
ALWAYS, when possible, reduce the number of
transitions and turns. If a long duct run is required,
increase duct size from 6” to 7” or 8”.
If turns or transitions are required: Install as far
away from opening and as far apart, between 2,
as possible.
Minimum mount height between range top to hood
bottom should be no less than 28”.
Maximum mount height should be no higher than
36”.
It is important to install the hood at the proper
mounting height. Hoods mounted too low could
result in heat damage and fire hazard; while hoods
mounted too high will be hard to reach and will
loose its performance and efficiency.
If available, also refer to range manufacturer’s
height clearance requirements and recommended
hood mounting height above range. Always check
your local codes for any differences.
Mounting Height (Recirculating or Ducted)
Minimum Ceiling Height 8’1”. Hood mounted 28”
above cooking surface; 64” from floor.
Maximum Ceiling Height 10’ 1”. Hood mounted
36” above cooking surface; 72” from floor.
Duct cover extension kit available for ceiling
heights up to 12 feet. Turn to page 18 for part
number and ordering information.
DAMAGE-SHIPMENT / INSTALLATION:
• Please fully inspect unit for damage before
installation.
• If the unit is damaged in shipment, return the
unit to the store in which it was bought for
repair or replacement.
• If the unit is damaged by the customer, repair
or replacement is the responsibility of the
customer.
• If the unit is damaged by the installer (if other
than the customer), repair of replacement must
be made by arrangement between customer
and installer.

Ductless recirculation is intended for applications where an exhaust duct work is not possible to be installed.
When converted, the hood functions as a recirculating hood rather than an exhaust hood. Fumes and exhaust
from cooking are drawn and filtered by a set of optional charcoal filters. The air is then purified and re-
circulated back within the home.
We recommend toALWAYS exhaust air outside of the home by employing existing or installing new duct
work, if possible. The hood is most effective and efficient as an exhaust hood. Only when the exhaust option
is not possible should you recourse to converting the hood into a recirculating hood.
When converted to be a recirculating hood, a set of charcoal filters are required on top of its standard Metal
Filter set. Order according to its Part number below. The standard Metal Filters are intended to capture
residue from cooking and the optional charcoal filters help to purify fumes exhausted from cooking for re-
circulation.
RECIRCULATING KIT (REQUIRED IF NO DUCTING IS USED)
Kit includes charcoal filters and air diverter plate.

1. Purchase recirculating kit per the part number above.
2. Secure air diverter plate to top support frame. (FIG. F) Open
sides of air diverter plate should face left and right and align
with louver holes on the duct covers. Run 6” ducting from top
of blower housing and secure to air diverter plate. See manual
included with recirculating kit for more detailed instructions.
3. Remove metal mesh filters from hood. Clip charcoal filters onto
each charcoal filter bracket. (FIG. G) The brackets are pre-installed and
located behind the mesh filters.
4. Re-install metal mesh filters.
5. Enable charcoal filter change indicator on control panel. (Refer details
to pg. 13)
6. Charcoal filters must be replaced after every 120 hours of use (or
approximately every 3 to 4 months based on the average of 1 to 2
hrs. of daily cooking time). The microprocessor in the controls when
set, will elapse and count usage time and indicate when charcoal filter
replacement is required every 120 hrs.
