Where is the model number located on my range?
On most Range Hoods the model number is located on a sticker on the inside of the hood. You may need to remove the filter in order to see the model number.
How do I clean my range hood?
MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE SERVICING THE UNIT. Clean your range hood with a mild detergent, such as dish washing liquid, and dry with a soft cloth. NEVER USE ANY ABRASIVE PADS OR SCOURING POWDERS. Completely dry before restoring power. NEVER IMMERSE ELECTRICAL PARTS IN WATER. The fan assembly can be vacuumed when build up (dirt, lint, etc.) accumulates over time.
How do I get a copy of the instruction sheets?
Instruction sheets can be downloaded from this web site. Please go to the "Product" section and navigate to your particular model or use the search feature at the top of the page to type in your model number.
Why do I need a range hood?
The function of a range hood is to prevent flare ups from the cooking surface from burning or in extreme case catching the cabinets above the cook top on fire. Range hood can also provide ventilation, helping to clear the cooking area of smoke, steam, odors, and grease generated from the cooking surface.
For under cabinet range hoods or hoods mounted against a wall the minimum air flow (CFM) is 40 CFM per linear foot. So a 36" range hood should provide a minimum of 120 CFM of exhaust. This is a mimum. the recommended amount is 100 CFM per linear foot. For a range hood mounted from the ceiling (island mounted range hood), the rates are higher. A minimum of 50 CFM and a recommended rate of 150 CFM per linear foot
NOTE: Always consult any applicable building codes in your area in regards to minimum and maximum air flow rates. Certian states may require additional items such as make-up air for larger CFM range hoods (typically over 300 CFM).

What is the difference between a ducted range hood and a ductless or duct free one?
As the name implies a ducted range hood ventilates the air in the cooking area outside through ductwork. A ductless or duct free range hood filters the air through a charcoal odor filter and recirculates the air back into the cooking area. A ducted range hood will be more effective and efficient at ventilating the cooking area, but in situations where ductwork is not an option a ductless range hood is a good alternative.
What is a Sone?
A sone is an internationally recognized unit of loudness. The sones translate laboratory decibel readings into numbers that correspond to the way people sense loudness. Double the sone is double the loudness. In everyday terms, one sone is equivalent to the sound of a quiet running refrigerator in a quiet kitchen. The lower the sone, the quieter the exhaust fan is.
I noticed ductless range hoods do not have CFM or Sone ratings, why?
With a ductless range hood, because the air is being recirculated and there is no actual ventilation taking place, there is no standard for measuring the CFM or the sone rating.

Is the width on the range hood's description, the actual size?
NO. The actual size of the range hood will be slightly less than the generic description of the range hood. For instance a 30" range hood will most likely measure 29-7/8". Refer to your particular model for the exact width.
How do I clean my grease filter and how often?
Your grease filter should be washed in hot water with detergent once a month. Make sure the filter is completely dry before reinstalling. Replace the grease filter if it becomes damaged, or too dirty to clean.
Can I clean my charcoal odor filter?
NO. Charcoal odor filters cannot be washed and must be discarded and replaced when they become noticeably dirty, have stopped filtering the odors, or at least once per year.
How high should my range hood be mounted from the cooking surface?
Air King recommends that the range hood be mounted between 20" and 30" from the cooking surface for maximum performance. As always - make sure to consult and adhere to your local and National codes when installing a Range Hood.

What is the best way to duct my range hood?
To maximize your range hood's performance, match your duct size to the original size of the fan’s ducting, use the shortest amount of ducting possible and keep the ducting as straight as possible. ALWAYS USE METAL DUCTWORK and avoid flexible ducting when possible.
Can I replace an old range hood or microwave with a new one?
YES. To help make the transition easy, make sure you know if the current unit is ducted or ductless, and if it is ducted, which way the ducting is running and the size. This will help you choose a proper replacement. When replacing a microwave, you will want to consider the height of the microwave compared to the height of the range hood and you might need to make height adjustments to insure proper ventilation.
Do I have to exhaust the range hood to the outdoors?
YES. If installing a range hood that has duct work connected to it (any hoods that do NOT recirculate the air back into the room), 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. A build up of humidity and grease could cause damage and/or a fire risk to your home.

My hood is operating but the air is moving slower than normal?
Check the filter for build up and clean or replace if needed. If the difficulty still persists, check for obstructions in the ductwork. A common obstruction is build up in the roof or wall cap such as birds nests or other debris.
My hood is making a rattling noise?
This is probably attributed to one of the following:
1. The motor is loose - turn off power to the unit, remove the filter and check that all screws are fully tightened around the motor.
2. The ductwork connection is loose - turn off power to the unit and check that the ductwork connect to the hood is tight. Add ducting tape if necessary.
What is make up air?
When the range hood ventilates air out of the room, the amount of air ventilated needs to be replaced, this is called make-up air. If there is not enough make up air, the range hood's performance will be diminished.
2. Make sure a speed has been selected at the range hood's controls.
3. Turn off power to the range hood and check that all wires are properly connected. Refer to your specific model's installation instructions for proper wiring instructions.
How do I order replacement parts?
Replacement parts can be ordered from the parts department by calling 1-800-465-7300 Monday thru Thursday 8am to 4pm, Friday 8am to 3pm Eastern Standard Time.
