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 fan, optional filter and 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 fan, filter, if any, and grease-laden surfaces clean.
Always turn hood ON when cooking at high heat.
Use high settings on cooking range ONLY when necessary. Heat the oil slowly on low to
medium setting.
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 fans frequently. Grease should not be allowed to accumulate on fan,
safety screens, and oil containers.

What to Do In The Event Of a Range Top Grease Fire
-SMOTHER FLAMES with a close 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 UPA 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.
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 may cause ignition or an explosion.
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.

UNDER THE CABINET INSTALLATION
SAFETY W ARNING
HOOD MAY HAVE VERY SHARP EDGES; PLEASE WEAR PROTECTIVE GLOVES IF IT
IS NECESSARY TO REMOVE ANY PARTS FOR INSTALLING, CLEANING, OR
SERVICING.
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. Refer to 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.
- Peel protective film off the hood (if any).
- For installing under the cabinets with recessed bottom, attach 4-inch wide wood filler
strips (not included) on each side. Refer to Figure 2.
- Measure and create access opening for electrical wires under the cabinet.
Figure 1 Figure 2

MAINTENANCE
CAUTION: NEVER PUT YOUR HAND INTO THE AREA HOUSING THE FAN WHILE THE
FAN IS OPERATING.
For the optimal level of operation, clean the range hood surface, safety screens, and oil
containers 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 an orange base cleaner to clean the
surface of the hood. Avoid cleaner to get on the control switches. Only spread a light
coating over the surface of the hood and leave on for a few minutes (do not leave on too
long or this may cause damage to hood finish). Use soft towel to wipe off the cleaning
solution, gently rubs any stubborn spots. Use a slightly damp towel to get rid of any
cleaning solution. Use dry soft towel to dry the hood.
3) To bring the glow back into a stainless steel finish, use a stainless steel cleaner.
4) DO NOT allow deposits to remain for long periods of time.
5) DO NOT use ordinary steel wool or steel brushes. Small bits of steel may adhere to the
surface causing rust.
6) 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 cloth.
To Clean Oil Containers, Safety Screens, and Impellers
CAUTION: DRAIN OIL CONTAINER BEFORE OIL CAN OVERFLOW.
1) Normal Cleaning
- Turn on high speed and spray a mild degreaser into the fan. Liquid residue will
accumulate in the oil containers.
2) Cleaning Oil Containers
- Remove the oil container (round) by turning counter-clockwise.
- Remove the oil container (oval) by sliding forward.
- Wash with warm soapy water. Dry completely before returning into place.
- Top rack dishwasher safe.
3) Cleaning Safety Screens
- Remove the safety screen screw and slide the safety screen out.
- Wash with warm soapy water. Dry completely before returning into place.
- Top rack dishwasher safe.

13
To Replace Light Bulb
CAUTION: HALOGEN LIGHT UNIT MAY BE HOT! WAIT UNTIL UNIT IS COOL.
1) Make sure all control switches are off, and range hood is unplugged.
2) Use a flat head screwdriver to pop out the protective covering as shown in Figure 18.
3) Gently pull out the defective light bulb and discard. Light bulbs should be 12V 20W
maximum. Refer to Figure 19. Push bulb securely into light socket.
4) Replace protective cover.
5) Plug in range hood.
