IMPORTANT SAFETY INSTRUCTIONS
- PLEASE READ THIS SECTION CAREFULLY BEFORE INSTALLATION -

 : 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

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

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.


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.

Preparation before Installation
NOTE: TO AVOID DAMAGE TO YOUR HOOD,
PREVENT DEBRIS FROM
ENTERING THE VENT OPENING.
x Decide the location of the venting pipe
from the hood to the outside. Refer to
Figure 1.
x A straight, short venting run will allow
the hood to perform more efficiently.
x Try to avoid as many transitions,
elbows, and long run as possible. This
may reduce the performance of the
hood.
x Temporarily wire the hood to test for
proper operation before installing.
x Peel protective film off the hood (if any).
x Make sure the cabinet has full access
opening for the hood as shown on
Figure 2.
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 on Table 1 and
measurements on page 11 mark the
leveling point for hood-mounting bracket
inside the cabinet.
2. Secure two hood mounting screws (not
provided) inside the cabinet leaving 1/8”
away from the cabinet as shown on Figure
3.
3. Loosen hood-mounting brackets at the
back of the hood, adjust brackets and
tighten screws as shown in Figure 4.
4. Refer to Figure 5. Align hood-mounting
bracket to the mounting screws inside the
cabinet and hook hood into place. Secure
and tighten the mounting screws.
CAUTION: MAKE SURE THE HOOD IS
SECURE BEFORE RELEASING.

Cleaning Hood Surface

 : 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 Baffle Filters
CAUTION: DRAIN BAFFLE FILTERS BEFORE OIL WILL OVERFLOW.
1. Remove the baffle filters by sliding forward and pull downward.
2. Wash with warm soapy water. Dry completely before returning into place.
(Note: Baffle Filters are top rack dishwasher safe.)

To Replace Light Bulb
CAUTION: HALOGEN LIGHT UNIT MAY BE HOT! WAIT UNTIL UNIT IS COOL.
NOTE: DO NOT TOUCH HALOGEN LIGHT WITH BARE HANDS, WHICH MIGHT CAUSE OVER
HEAT AND SHORTEN THE LIFT OF LIGHT BULBS.

The range
hood is not
venting out
correctly.
The range hood is installed outside of
the manufacture recommended
clearance.

and cook top to 27” to 30”. For Island range
hood, the clearance between the range hoods
and cook top is 30” to 36”.
There is no make-up air inside the
house.
Open the window to enhance the performance
of the range hood by creating a sufficient make-
up air.
Obstacle blocking the pipe work. Remove all obstacles from the duct work.
The pipe size is smaller than the
suggested pipe size.
Change the ducting according to the
manufacture suggestion.
Cold air is
coming into the
home.
The pipe connection is not properly
sealed.
Check the pipe installation.
The damper is not properly installed or
is missing from the installation.
