IMPORTANT SAFETY INSTRUCTIONS
-PLEASE READ THIS SECTION CAREFULLY BEFORE INSTALLATION -
WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR PERSONAL
INJURY, OBSERVE THE FOLLOWING:
1) Installation and electrical wiring must be done by qualified professionals and in accordance with all
applicable codes and standards, including fire-rated construction.
2) When cutting or drilling into wall or ceiling, be careful not to damage electrical wiring or other hidden
utilities.
3) Ducted fans must be vented to the outside.
a) Before servicing or cleaning unit, open the light panel and SWITCH POWER OFF AT SERVICE
PANEL.
b) Clean all grease laden surfaces frequently. To reduce the risk of fire and to disperse air
properly, make sure to vent air outside. DO NOT vent exhaust air into wall spaces, attics, crawl
spaces or garages.
NOTE
-
This warranty is invalid without an authorized agent’s receipt or if unit is
damaged due to misuse, poor installation, improper use, mistreatment,
negligence or any other circumstances beyond the control of KOBE
RANGE HOODS authorized agents. Any repair carried out without the
supervision of KOBE RANGE HOODS authorized agents will
automatically void the warranty.
-
KOBE RANGE HOODS will not be held responsible for any damages to
personal property or real estate or any bodily injuries whether caused
directly or indirectly by the range hood.
WARNING: TO REDUCE THE RISK OF PERSONAL INJURY IN THE EVENT OF A
RANGE TOP GREASE FIRE:
•Keep all fan, baffle/spacer/filter/oil tunnel/oil container and grease-laden surfaces clean. Grease
should not be allowed to accumulate on fan,baffle/spacer/filter/oil tunnel/oil container.
•Always turn hood ON when cooking.
•Use high settings on cooking range ONLY when necessary.
•Do not leave cooking range unattended when cooking.
•Always use cookware and utensils appropriate for the type and amount of food prepared.
•Use this unit only in the manner intended by the manufacturer.
•Before servicing, switch power off at service panel and lock service panel (if possible) to prevent
power from switching on accidentally.
•Clean ventilating fan frequently.

What to Do In The Event Of a Range Top Grease Fire
• SMOTHER FLAMES with a tight fitting lid, cookie sheet, or metal tray, and then turn off the burner.
KEEP FLAMMABLE OR COMBUSTIBLE MATERIAL AWAY FROM FLAMES. If the flames do not
go out immediately, EVACUATE THE AREA AND CALL THE FIRE DEPARTMENT or 911.
• NEVER PICK UP A BURNING PAN –You May Get Burned.
• DO NOT USE WATER, including wet dishcloths or towels –a violent steam blast will result.
• Use an extinguisher ONLY if:
a) You have a Class A, B, C extinguisher and know how to operate it.
b) The fire is small and contained in the area where it started.
c) The fire department has been called.
d) You can fight the fire with your back to an exit.
What to Do If You Smell Gas
- Extinguish any open flame.
- Do not try to turn on the lights or any type of appliance.
- Open all doors and windows to disperse the gas. If you still smell gas, call the Gas Company and
Fire Department right away.
CAUTION
1) For general ventilation use only. Do not use to exhaust hazardous or explosive materials and
vapors.
2) To reduce the risk of fire, use only metal ductwork. Sufficient air is needed for proper combustion
and exhausting of gases through the flue (chimney) to prevent back drafting.
3) 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 code authorities.
4) Activating any switch on may cause ignition or an explosion.
5) Due to the size and weight of this hood, two people installation is recommended.
ELECTRICAL SHOCK HAZARD – Can result in serious injury or
death. Disconnect appliance from electric power before servicing.
If equipped, the fluorescent light bulb contains small amounts of
mercury, which must be recycled or disposed of according to
Local, State, and Federal Codes.

Preparation before Installation
NOTE: TO AVOID DAMAGE TO YOUR HOOD,
PREVENT DEBRIS FROM ENTERING
THE VENT OPENING.
- Decide the location of the venting pipe from
the hood to the outside. (Figure 1)
- A straight, short venting run will allow the
hood to perform more efficiently.
- Try to avoid as many transitions, elbows,
and long run as possible. This may reduce
the performance of the hood.
- Temporarily wire the hood to test for proper
operation before installing.
- Important: Peel any protective film off the
hood.
- Use duct tape to seal the joints between
pipe sections.
- If necessary, prepare back wall frame with
cross framing lumber for secure installation.
Refer to Table 1 and measurements on
Page 12 to decide the level of the lumber.
(Figure 2)
- Loosen hood-mounting brackets at the back
of the hood, adjust brackets and tighten
screws as shown in Figure 3.
- If necessary,remove the rubber stand on
the back of the hood and discard.
Hood Installation
CAUTION: If required to move the
cooking range to install the hood, turn
off the power on an electric range at the
main electrical box. SHUT OFF THE
GAS BEFORE MOVING A GAS RANGE.
1. Using references in Table 1 and
measurements on Page 12, mark the

Cleaning Hood Surface
CAUTION: NEVER USE ABRASIVE CLEANERS, PADS, OR CLOTHS. DO NOT USE
PAPER TOWEL ON STAINLESS STEEL.
For optimal operation, clean range hood and all baffle/spacer/filter/oil tunnel/oil container regularly.
*** Regular care will help preserve the appearance of the hood.
1. Use only mild soap or detergent solutions. Dry surfaces using soft cloth.
2. If hood looks splotchy (stainless steel hood), use a stainless steel cleaner to clean the surface of the
hood. Avoid getting cleaning solution onto or into the control panel. Follow directions of the stainless
steel cleaner. Caution: Do not leave on too long as this may cause damage to hood finish. Use
soft towel to wipe off the cleaning solution, gently rub off any stubborn spots. Use dry soft towel to
dry the hood.
3. DO NOT allow deposits to accumulate or remain on the hood.
4. DO NOT use ordinary steel wool or steel brushes. Small bits of steel may adhere to the surface and
cause rusting.
5. DO NOT 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 lint free cloth.
To Clean Aluminum Filters
1. Remove all the aluminum filters.
2. Wash with warm soapy water. Dry completely before returning into place.
