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 void 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:
1. 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.
2. Always turn hood ON when cooking.
3. Use high settings on cooking range ONLY when necessary.
4. Do not leave cooking range unattended when cooking.
5. Always use cookware and utensils appropriate for the type and amount of food prepared.

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 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, installation by 2 persons 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.

SAFETY WARNING
•HOOD MAY HAVE SHARP EDGES; PLEASE WEAR PROTECTIVE GLOVES IF REMOVING
ANY PARTS FOR INSTALLING, CLEANING, OR SERVICING.
•BE CAREFUL WHEN USING ELECTRICAL SCREWDRIVER, DAMAGE TO THE HOOD MAY

•MAKE SURE TO PREVENT ANY DEBRIS FROM ENTERING THE VENT OPENING TO AVOID
DAMAGE OR MALFUNCTION.
WALL MOUNT INSTALLATION
**Installation videos available at www.koberangehoods.com**
1. Read any provided document(s).
2. Test the range hood by temporarily connecting to an outlet and turning ON the fan and lights.
3. If you run into any problems, contact KOBE Range Hoods.
4. This range hood has top 6” round exhaust.
5. Decide the location of the venting pipe from the hood to the outside. A straight, short vent run will
allow the hood to perform more efficiently. Try to avoid elbows, transitions, and long run as much
as possible as this may reduce the performance of the hood. Make sure that the duct work leads
to the outside.
Before Installation
Venting Requirements

5
6. It is recommended to use metal/aluminum duct/pipe with a
uniform size (ex. 6” round pipe from range hood to the outside).
7. If an elbow is necessary, a minimum of 12” straight run is
necessary before the elbow.
8. Clearance is the distance between the cooktop and the bottom
of the range hood. The recommended minimum clearance for
this model is 26” and the maximum clearance is 30”.
9. It is important to install the hood at the recommended
clearance. Installing too low could result in damage and/or fire
hazard while installing too high may result in reduced
performance and efficiency.
10. The first step is to secure the mounting screws on the wall. It
is important that the screws are hitting the wall studs. If
necessary, install a cross lumber frame in the wall as shown in
figure 1.
11. Attach the mounting screws on the wall, leaving about 1/8 of
an inch between the wall and the end point of the screws since
this is where you will hang your hood. Refer to figure 2.
12. Align the hood-mounting bracket to the screws on the wall and
hook into place. Then tighten the screws to secure the hood to
the wall.
CAUTION: MAKE SURE THE HOOD IS SECURE
BEFORE RELEASING.
13. Attach the vent adapter to the exhaust opening using the 4 x 8
mm screws.
14. Connect the pipe onto the vent adapter and seal the joint with
duct tape. Make sure that it is completely air tight.
15. Attach the two ductcover mounting bracket on the wall as seen
on figure 4.
16. Place the inner duct cover and outer duct cover over the range
hood.
17. Secure the outer duct cover to the range hood body with the 5
x 12 mm screws provided.
18. Pull the inner duct cover up until it aligns properly to the duct
cover mounting bracket, then secure to the duct cover
mounting bracket with 5 x 12 mm screws. Refer to figure 3 and
4.
19. Connect the range hood to an outlet.
20. If hardwired is desired, cut off the plug and connect three wires
(black, white, green) to the outlet wires and cap with wire
connectors. Connect the wires according to color (ex: black to
black).

MAINTENANCE
For optimal performance, clean the range hood surface and baffles regularly.
To Clean Hood Surface
CAUTION: NEVER USE ABRASIVE CLEANERS, PADS, OR CLOTHS.
*** Regular care will help preserve its fine appearance.
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.
For Baffle Filter models only: to Clean Baffle Filter/Oil Tunnel
CAUTION: DRAIN OIL FROM BAFFLE FILTERS, SPACERS & OIL TUNNEL REGULARLY TO
PREVENT OVERFLOW.
1. Remove all the baffle filters, spacers and oil tunnel. Note: Not all models have spacers and oil
tunnels.
2. Using a sponge, wash with warm soapy water. Dry completely before returning into place.
CAUTION: SHARP EDGES (Note: Baffle Filters are top rack dishwasher safe.)
