CAUTION:
·
·
Locate the cooking area for minimum cross drafts—away from doors and windows, when possible.
Ducts must be of adequate size and duct runs should be as short as possible. Where turns are necessary,
keep turning radius as large and as smooth as possible.
·
·
The ducting must be air tight. Use a minimum of 2 sheet metal screws at every duct joint. Then, seal the duct
joints with high quality duct tape.
Only use ductwork constructed of materials deemed acceptable by state, municipal and local codes.
1. A qualified person must complete the installation of this appliance.
2. Plan the installation so that all minimum clearances are met or exceeded. Dimensions shown provide minimum
clearances, unless otherwise specified.
3. IMPORTANT: If the Air-O® hood is installed as a liner for a wood hood, proper installation of the hood as a liner
is directly related to the material from which the custom canopy is constructed. You must provide structural
framing and tight backing in the areas in which you are securing the liner inside your custom canopy. Failure to
do so could distort and damage the liner and void the warranty.
IMPORTANT: Hood is 1/8” narrower than widths shown below.
Dimensions
WARNING! Following Are Manufacturer’s Suggestions. Always Observe Local Building Codes.
Hoods installed in custom canopies constructed of combustible materials should be installed with the combustible
material structure a minimum of 36” above the cooking surface. Hoods installed in custom canopies constructed of
non-combustible materials, should be installed with the non-combustible material structure a minimum of 30” above
the cooking surface. Follow all instructions regarding minimum safe clearances and installation location. Failure to
do so may result in a safety hazard or fire. To reduce the risk of fire use only metal ductwork.

PART 2 Electrical Connection
WARNING!
Ensure that the power supply is disconnected before proceeding. Verify that the power supply matches the ratings
found on the appliance data label before proceeding. The complete appliance must be properly grounded at all
times when electrical power is applied. Do not ground the appliance with the neutral (white) house supply wire. A
separate ground wire must be utilized. Failure to complete electrical connections properly may result in damaged
or non-functional systems. Follow instructions carefully to ensure proper installation.
It is the owner’s responsibility to ensure that a qualified person performs the electrical connection of this
appliance. The electrical installation, including minimum supply wire size, must comply with the National
Electric Code ANSI/NFPA 70-1990 (or latest revision) and local codes and ordinances. A copy of this
standard may be obtained from:
National Fire Protection Association, 1 Batterymarch Park, Quincy, Massachusetts 02169-7471
INSTRUCTIONS:
A 15 to 20 amp electrical service is recommended for proper electrical supply. Always observe local building
codes. Always use a dedicated circuit. The Air-O® hood is supplied with a 5.0 amp variable speed fan control.

PART 3 Determining Direction of Vent and Securing the Hood
MOUNTING HOLES
Because the Air-O® Ultra Series rangehood was designed for all applications, no mounting holes have been pre-
drilled. This allows the hood (or liner) to be attached in the areas of the cabinet or wood hood canopy that have
proper wood frame support. The hood should be attached to the wood framing through the top. Remove the filters.
Mark and drill screw holes through the hood as required. Secure the hood by driving screws (provided by others)
through the screw holes. NOTE: DRILLING THROUGH STAINLESS STEEL REQUIRES TITANIUM DRILL BITS.
BE CAREFUL NOT TO DRILL THROUGH THE UL LABEL OR INTO THE HOOD’S ELECTRICAL COMPONENTS.
DETERMINING THE DIRECTION OF VENTING (TOP, REAR AND RECIRCULATE):
TOP VENT
BACK VENT
RECIRCULATION
Top Vent: Range hoods are shipped with the motor and blower installed to vent out the top. However, the vent
covers in the rear vent opening and recirculation vent opening must be taped on all edges to prevent air leaks and
vibration noise. The vent covers are not taped when shipped from the factory because the direction of venting may
be changed. Vent covers placed on the inside of the hood should be neatly foil taped. Duct covers placed on the
outside of the hood can be duct taped. If the rear vent and recirculation vent covers are not already in place,
slightly bow the vent cover and place the side slots over both sides of the vent openings. Tightly fasten the motor &
blower housing to the studs on the hood top. When installed correctly, the motor & blower housing will be
approximately ½” from the back wall of the hood.
Back Vent: Unplug the electrical connection and remove the motor & blower housing from the hood.
IMPORTANT: Remove the vent cover from the rear vent opening. Slightly bow the vent cover removed from
the rear vent opening and place the side slots over both sides of the top vent opening. The vent cover can be
placed on the inside or outside of the hood. We recommend the inside. Vent covers placed on the inside of the
hood should be neatly foil taped. Vent covers placed on the outside of the hood can be duct taped. Vent covers
must be taped on all edges to prevent air leaks and vibration noise. Do not re-use the pieces of duct tape shipped
with the hood. Reposition the blower housing to vent out the back of the hood and align the housing mounting
brackets so that the housing tightly fits against the back wall. Securely fasten the motor & blower housing to the
studs on the hood top. Reconnect the electrical connectors.
Recirculation: Unplug the electrical connection and remove the motor & blower housing from the hood.
IMPORTANT: Remove the vent cover from the front vent opening. Slightly bow the vent cover removed from
the front vent opening and place the side slots over both sides of the top vent opening. The vent cover can be
placed on the inside or outside of the hood. We recommend the inside. Vent covers placed on the inside of the
hood should be neatly foil taped. Vent covers placed on the outside of the hood can be duct taped. Vent covers
must be taped on all edges to prevent air leaks and vibration noise. Do not re-use the pieces of duct tape shipped
with the hood. Reposition the blower housing to vent out the front of the hood and align the housing mounting
brackets so that the housing tightly fits against the front wall. Securely fasten the motor & blower housing to the
studs on the hood top. Reconnect the electrical connectors.
CONNECTING TO THE VENT PIPE:
The hood is equipped with a metal damper. Attach the damper to the hood top or back side of the hood with at
least two screws. Duct tape the edges to the hood. Be careful to not damage or tape over the damper blade.
When connected to the back of the hood (horziontal ventilation), be sure the damper swings open from the bottom
side; the hinge will be on the top. Otherwise, it will NOT close when the motor is off.

PART 4 Use and Care
OPERATING CONTROLS:
Always activate the ventilator when using cooking appliances. Activate the ventilator a few minutes before starting
to cook to establish an airflow pattern within the room. Adjust the fan speed as needed. Adjust the dimmable
halogen lights as desired. Eliminate air currents in the hood vicinity by shutting nearby windows and doors, turning
off ceiling fans and adjusting the adjacent heating and air conditioning outlets if necessary. Place your largest pans
on the rear burners whenever possible.
WARNING!
Do NOT operate the blower / ventilator system without the filters in place, or with dirty, grease laden filters.
ENERGY SAVING TIPS:
Do not operate the blower at a speed higher than necessary to remove the cooking exhaust. Running at excessive
speeds removes more air from the inside of the house that must be replaced by outside air. This may be especially
costly when your home’s heating or air conditioning system is in operation. Turn off the unit once the smoke and
cooking odors have been eliminated. Clean filters and grease laden surfaces often to improve efficiency. Always
use lids on cookware to retain heat and moisture. Minimize the amount of liquid used to cook food. Select
cookware of proper size, material and construction for the cooking task being performed.
CARE & CLEANING:
Proper cleaning is necessary to maintain performance and appearance, while also ensuring safe operation.
The frequency of cleaning should be adjusted according to the type and amount of cooking. Best results will be
achieved by cleaning soiled components as soon as possible. Filters must be cleaned regularly. Remove one filter
at a time by inserting a butter knife in the slot and pressing back then downwards. Butter knife filter slots are a
safety feature. The filter should be installed with the butter knife slot on the front lower side.
The filters may be cleaned by hand washing in hot water using a mild detergent solution, or by placing them in a
dishwasher. Dry the filters completely before using again. Stainless steel surfaces should be cleaned with a
solution of mild detergent and warm water. Rinse and dry with a soft lint-free cloth. Charcoal filters are ineffective if
washed and should be replaced periodically. Contact your dealer or Universal Metal Industries for replacement.
CAUTION: If a commercially available stainless steel cleaner is used, it is important to read the labels for chlorine
compounds. Chlorine is a corrosive substance. If these compounds are present, rinse thoroughly and dry with a
soft lint-free cloth. Follow polish manufacturer’s instructions. Always wipe stainless steel surfaces with the grain.
Never wipe across the grain. After cleaning, reinstall the filters carefully. Most common scrubber type pads will
scratch the hood.
HALOGEN LIGHT BULBS:
UM200 hoods are designed for Par 20 halogen lamps. They can be purchased at most home and/or grocery
stores, e.g., Lowe’s, Menards, Fry’s, Kroger, Ace Hardware, Albertsons, True Value, and Home Depot.
